Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 24 June 2026 has been entered. Response to Amendment Applicant’s response, filed 24 June 2026, to the last office action has been entered and made of record. In response to the amendments to the claims, they are acknowledged, supported by the original disclosure, and no new matter is added. Amendments to the independent claims 1, 13, and 16 have necessitated a new ground of rejection over the applied prior art. Please see below for the updated interpretations and rejections. Response to Arguments Applicant’s arguments with respect to amended independent claims 1, 13, and 16 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 1, 3-9, 11-13, 15-16, and 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US 2022/0083797, effectively filed 28 December 2018), herein Kim, in view of McElvain et al. (US 2021/0243352, effectively filed 7 September 2018), herein McElvain, Jung et al. (US 2016/0267333), herein Jung, and Watanabe et al. (US 2022/0232182, effectively filed 10 May 2019), herein Watanabe. Regarding claim 1, Kim discloses a target recognition method, comprising: performing first image processing on first image data to obtain first artificial intelligence (AI) input data (see Kim [0082]-[0084] and [0092]-[0094], where image enhancement processing is performed on received images to improve recognition rate of an object included in the received image, where deblur, denoise, wide dynamic range (WDR) or high dynamic range (HDR), color tone mapping, and demosaicing image processing may be performed, and the preprocessed image is input to an input layer of an artificial neural network for object recognition); performing target recognition on the first AI input data to obtain first target recognition results (see Kim [0087]-[0089] and [0092]-[0094], where the preprocessed image is input to an input layer of an artificial neural network for object recognition). Kim does not explicitly disclose wherein the first image data comprises first raw image data from an image sensor; performing second image processing on second image data to obtain second AI input data, wherein the second image data comprises second raw image data from the image sensor, and wherein a first exposure duration corresponding to the first AI input data is different from a second exposure duration corresponding to the second AI input data, or a first dynamic range corresponding to the first AI input data is different from a second dynamic range corresponding to the second AI input data. McElvain teaches in a related and pertinent auto exposure method for a spatially-multiplexed-exposure (SME) high-dynamic-range (HDR) image sensor (see McElvain Abstract), where raw image data, including long exposure, middle exposure, and short exposure pixel values characterized by long, middle, and short exposure times, are retrieved from the SME HDR image sensor and preprocessed to remove pixel values that fail to meet one or more quality requirements (see McElvain [0071]-[0075], [0095]-[0097] and [0105]-[0106]), where long exposure pixel values and short exposure pixel values may be separately filtered to remove long exposure pixel values that are saturated and short exposure pixel values that are significantly affected by noise (see McElvain [0073]), synthesizing the long, middle, and short exposure pixel values into an HDR histogram and iteratively performing processing steps to optimize the exposure times for the image sensor (see McElvain [0075]-[0084] and [0106]-[0109]), and generate an HDR image from the captured image data after iterations of the auto exposure processing (see McElvain [0085]). At the time of filing, one of ordinary skill in the art would have found it obvious to apply the teachings of McElvain to the teachings of Kim, such that the received images are captured with an image sensor as taught by McElvain, including long, middle, and short exposure pixel data, and that the image enhancing processing is performed separately on each of the corresponding long, middle, and short exposure pixel data and used to generate a corresponding HDR image. This modification is rationalized as an application of a known technique to a known method ready for improvement to yield predictable results. In this instance, Kim discloses a base method for recognizing an object in an image, where received images are preprocessed to improve the recognition rate of an object included in the received image, where deblur, denoise, wide dynamic range (WDR) or high dynamic range (HDR), color tone mapping, and demosaicing image processing may be performed, and that the preprocessed image is input to an input layer of an artificial neural network for object recognition. McElvain teaches a known technique of capturing raw image data, including long exposure, middle exposure, and short exposure pixel values characterized by long, middle, and short exposure times, from a spatially-multiplexed-exposure (SME) high-dynamic-range (HDR) image sensor, preprocessing the long exposure, middle exposure, and short exposure pixel values to remove pixel values that fail to meet one or more quality requirements, and generating an HDR image from the captured image data after iterations of the auto exposure processing. One of ordinary skill in the art would have recognized that by applying McElvain’s techniques would allow for the method of Kim to capture the received images with an SME HDR image sensor as taught by McElvain, including long, middle, and short exposure pixel data, and that the image enhancing processing is performed separately on each of the corresponding long, middle, and short exposure pixel data and used to generate a corresponding HDR image to be input to the artificial neural network for performing object recognition, predictably leading to an improved method for recognizing an object in an image, where long, middle, and short exposure pixel data are captured by an SME HDR image sensor to be enhanced and used to generate an improved HDR image for improved recognition rate of an object. While Kim and McElvain disclose that the term “image” may include a plurality of images or video (see Kim [0040]) and further performing auto exposure of captured video streams where an HDR image is produced for each frame of the captured video stream (see McElvain [0170]-[0173]); Kim and McElvain do not explicitly disclose wherein the first AI input data is a video frame image generated from the first raw image data; and wherein the second AI input data is a video frame image generated from the second raw image data. Jung teaches in a related and pertinent system and method for forward vehicle detection using multi-exposure camera (see Jung Abstract), where a long and short exposure frames are selected from among a sequence of multi exposure frames captured from a multi-exposure camera (see Jung [0032], [0037] and [0042]-[0044]), and the long and short exposure frames are processed to label candidate BLOB regions to perform BLOB detection and tracking (see Jung Fig. 5, Fig. 6, [0037], and [0048]-[0056]). At the time of filing, one of ordinary skill in the art would have found it obvious from Jung’s teachings in view of the combined teachings of Kim and McElvain, that multi exposure image frames captured from video streams are used as input to perform object detection and tracking, where the multi-exposure frames are preprocessed to improve the recognition rate of an object. This modification is rationalized as some teaching, suggestion, or motivation in the prior art that would have led one of ordinary skill to modify the prior art reference or to combine prior art reference teachings to arrive at the claimed invention. In this instance, Kim and McElvain teach a method for recognizing an object in an image, where received images, including long, middle, and short exposure images are captured with a SME HDR image sensor, and image enhancing processing is performed on the corresponding long, middle, and short exposure pixel data and used to generate a corresponding HDR image to be input to the artificial neural network for performing object recognition, where an image can be a plurality of captured images or video, and that auto exposure of captured video streams where an HDR image is produced for each frame of the captured video stream. Jung further teaches that long and short exposure frames are selected from among a sequence of multi exposure frames captured from a multi-exposure camera, where the long and short exposure frames are processed to label candidate BLOB regions to perform BLOB detection and tracking. One of ordinary skill in the art would understand from the combined teachings of Kim, McElvain, and Jung that multi exposure image frames captured from video streams can be used as input to perform object detection and tracking, where the multi-exposure frames are preprocessed to improve the recognition rate of an object. While Kim teaches that the preprocessed image is input to an input layer of an artificial neural network for object recognition (see Kim [0087]-[0089] ad [0092]-[0094]); Kim, McElvain, and Jung do not explicitly disclose performing target recognition separately on the first AI input data to obtain first target recognition results and on the second AI input data to obtain second target recognition results; and generating target information representing a final target recognition result by combining the first target recognition results and the second target recognition results. Watanabe teaches in a related and pertinent image recognition device and method (see Watanabe Abstract), where a camera image sensor captures short and long exposure images to generate a high dynamic range image and recognize a subject in the captured image (see Watanabe [0024] and [0029]-[0033]), and that a recognition unit, including first and second deep neural network (DNN) units, can process the short and long exposure images to recognize the subject captured in the short and long exposure images to improve the accuracy in recognizing the subject by avoiding secondarily generated artifacts from the HDR image generation process (see Watanabe [0040]-[0052]), where the disclosed embodiment is understood to process the short exposure image with the first DNN unit and generate first recognition results information in parallel with processing the long exposure image with the second DNN unit and generate the second recognition results (see Watanabe Fig. 2 and [0055]-[0057]), and a final recognition result information is determined based on both the first and second recognition result information (see Watanabe Fig. 2 and [0058]). At the time of filing, one of ordinary skill in the art would have found it obvious to apply the teachings of Watanabe to the teachings of Kim, McElvain, and Jung, such that the object recognition rate can be further improved by also processing the preprocessed long, middle, and short exposure images by respective object recognition neural networks for each preprocessed exposure images and determining a final recognition result based on the combined recognition result information from the respective object recognition neural networks for each preprocessed exposure images. This modification is rationalized as an application of a known technique to a known method ready for improvement to yield predictable results. In this instance, Kim, McElvain, and Jung disclose a base method for recognizing an object in an image, where received images, including long, middle, and short exposure images are captured with a SME HDR image sensor, and image enhancing processing is performed on the corresponding long, middle, and short exposure pixel data and used to generate a corresponding HDR image to be input to the artificial neural network for performing object recognition. Watanabe teaches a known technique of using a first and second deep neural network to process short and long exposure images in parallel to recognize the subject captured in the respective short and long exposure images and determining a final recognition result information based on both the first and second recognition result information to improve the accuracy in recognizing the subject by avoiding secondarily generated artifacts from the HDR image generation process. One of ordinary skill in the art would have recognized that by applying Watanabe’s techniques would allow for the method of Kim, McElvain, and Jung to further input the preprocessed long, middle, and short exposure images, along with the HDR preprocessed image, to respective object recognition neural networks and determine a final recognition result based on the combined recognition result information from the respective object recognition neural networks for each preprocessed exposure images, predictably leading to an improved method for recognizing an object by further inputting preprocessed long, middle, and short exposure images to the object recognition neural network to account for possibly generated artifacts in the inputted HDR image and further improving the object recognition rate. Regarding claim 3, please see the above rejection of claim 1. Kim, McElvain, Jung, and Watanabe disclose the target recognition method of claim 1, further comprising receiving, from the image sensor, an image data stream, wherein before performing the first image processing and the second image processing, the target recognition method further comprises splitting the image data stream to obtain the first image data and the second image data (see McElvain [0170]-[0173], where raw image data can be retrieved from a frame of a video stream captured by the SME HDR image sensor, including long exposure pixel values, short exposure pixel values, and middle exposure pixel values; see Watanabe [0029]-[0030], where the imaging unit can capture, in one frame period, images with different sensitivities, corresponding to short exposure images and long exposure images).

see McElvain [0004] and [0056], where an image with a longer exposure time is captured to get good image data for darker portions of the scene, and that the SME HDR image sensor captures long and short exposure pixel data for generating HDR imagery; where the combined teachings suggests preprocessed long exposure image data is processed by the object recognition neural network to perform object recognition); obtaining, based on the fourth AI input data, third target information corresponding to the intermediate area (see McElvain [0071]-[0075], [0095]-[0097] and [0105]-[0106], where raw image data, includes long exposure, middle exposure, and short exposure pixel values characterized by long, middle, and short exposure times, are retrieved from the SME HDR image sensor and preprocessed to remove pixel values that fail to meet one or more quality requirements; see Watanabe [0040]-[0052], where the exposure images are further processed by the DNN units to recognize the subject captured in the short and long images; where the combined teachings suggests to further include preprocessed middle exposure images to the object recognition neural network to improve object recognition rates); and obtaining, based on the first AI input data, fourth target information corresponding to an area other than the bright area, the dark area, and the intermediate area in the target scene (see Kim [0087]-[0089] and [0092]-[0094], where the preprocessed image, including WDR or HDR processing, is input to an input layer of an artificial neural network for object recognition; where the combined teachings suggests HDR preprocessed images generated from long, middle, and short exposure image data is processed by the object recognition neural network to perform object recognition). Regarding claim 13, it recites an apparatus performing the method of claim 1. Kim, McElvain, Jung, and Watanabe teach an apparatus performing the method of claim 1. Please see above for detailed claim analysis, with the exception to the following further limitations: a memory configured to store instructions (see Kim [0095]-[0102], where the disclosed teachings can be implemented by executing software instructions stored on a computer readable medium, such as random-access memory (RAM), read-only memory (ROM), or other medium that can carry or store desired program code); and a processor coupled to the memory and configured to execute the instructions to perform the method of claim 1 (see Kim [0095]-[0102], where the instructions may be executable by one or more processors to perform certain aspects of the disclosed teachings) Please see the above rejection for claim 1, as the rationale to combine the teachings of Kim, McElvain, Jung, and Watanabe are similar, mutatis mutandis. Regarding claim 15, see above rejection for claim 13. It is an apparatus claim reciting similar subject matter as claim 3. Please see above claim 3 for detailed claim analysis as the limitations of claim 15 are similarly rejected. Regarding claim 16, it recites a computer program product comprising instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause a target recognition apparatus to perform the method of claim 1. Kim, McElvain, Jung, and Watanabe teach a computer program product comprising instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause an apparatus to perform the method of claim 1 (see Kim [0095]-[0102], where the disclosed teachings can be implemented by executing software instructions stored on a computer readable medium, such as random-access memory (RAM), read-only memory (ROM), or other medium that can carry or store desired program code, by one or more processors). Please see above for detailed claim analysis. Please see the above rejection for claim 1, as the rationale to combine the teachings of Kim, McElvain, Jung, and Watanabe are similar, mutatis mutandis. Regarding claim 18, see above rejection for claim 16. It is a computer program product claim reciting similar subject matter as claim 3. Please see above claim 3 for detailed claim analysis as the limitations of claim 18 are similarly rejected. Regarding claim 19, see above rejection for claim 16. It is a computer program product claim reciting similar subject matter as claim 4. Please see above claim 4 for detailed claim analysis as the limitations of claim 19 are similarly rejected. Regarding claim 20, see above rejection for claim 19. It is a computer program product claim reciting similar subject matter as claim 5. Please see above claim 5 for detailed claim analysis as the limitations of claim 20 are similarly rejected.
