Office Action

§102
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 . 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 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. Priority Receipt is acknowledged of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement The information disclosure statement (IDS) submitted on 02/08/2024 has been considered by the examiner. The submission is in compliance with the provisions of 37 CFR 1.97. Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Claim Rejections - 35 USC § 102 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 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 following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1 – 2, 4 – 8, and 10 – 11 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kaifu (US PgPub No. 20130135543). Regarding claim 1, Kaifu teaches a dimming apparatus (figure 1) comprising: a dimming element that adjusts an amount of light reaching an imaging element from a subject at a time of imaging (figures 1 – 2 item 31) according to an applied voltage (figures 3A – 5B); a driver that applies a drive voltage to be inverted to the dimming element (figure 1 item 34 and figure 4 drive voltage V1 going from high value towards 0); and a controller that controls the driver, wherein the controller controls the driver to change a drive frequency of the drive voltage according to a preset length of an exposure time of the imaging element (figure 1 item 33 controlling item 34 and figure 4 change the transmittance over time of exposure; also paragraphs 0056 and 0065). Regarding claim 2, as mentioned above in the discussion of claim 1, Kaifu teach all of the limitations of the parent claim. Additionally, Kaifu teaches wherein the controller increases the drive frequency as the exposure time is longer (figure 1 item 33 controlling item 34 and figure 4 change the transmittance over time of exposure as needed; also paragraphs 0056 and 0065). Regarding claim 4, as mentioned above in the discussion of claim 1, Kaifu teach all of the limitations of the parent claim. Additionally, Kaifu teaches wherein the controller synchronizes the drive voltage with a drive signal of the imaging element (figure 1 item 22 sends signal to item 33, item 33 sends signal to item 34 for driving item 31). Regarding claim 5, as mentioned above in the discussion of claim 4, Kaifu teach all of the limitations of the parent claim. Additionally, Kaifu teaches wherein the controller changes the drive voltage before or after a predetermined time of a change in the drive signal of the imaging element (figure 4 also figure 1 item 22 sends signal to item 33, item 33 sends signal to item 34 for driving item 31; figure 1 item 33 controlling item 34 and figure 4 change the transmittance over time of exposure; also paragraphs 0056 and 0065). Regarding claim 6, as mentioned above in the discussion of claim 4, Kaifu teach all of the limitations of the parent claim. Additionally, Kaifu teaches a light shielding element that shields light reaching the imaging element from the subject at the time of imaging, wherein the controller synchronizes the drive voltage with a timing of light shielding by the light shielding element (figures 2, 5A – 5B, 7, 9, and 13 - 16; item M). Regarding claim 7, as mentioned above in the discussion of claim 1, Kaifu teach all of the limitations of the parent claim. Additionally, Kaifu teaches a light shielding element that shields light reaching the imaging element from the subject at the time of imaging, wherein the controller controls a timing of shielding of the light by the light shielding element, and changes the drive voltage while the light shielding element shields the light (figures 2, 5A – 5B, 7, 9, and 13 - 16; item M; figure 1 item 22 sends signal to item 33, item 33 sends signal to item 34 for driving item 31). Regarding claim 8, as mentioned above in the discussion of claim 4, Kaifu teach all of the limitations of the parent claim. Additionally, Kaifu teaches wherein the controller sets an output time interval of a drive signal of the imaging element to be longer than a sum of a read time and the exposure time of the imaging element (paragraphs 0040, 0059, and 0070; the image quality improvement processing section 43 performs the predetermined image quality improving process on the picked-up image signal S1 to generate the picked-up image signal Sout subjected to the image quality improving process). Regarding claim 10, as mentioned above in the discussion of claim 1, Kaifu teach all of the limitations of the parent claim. Additionally, Kaifu teaches wherein the dimming element includes a liquid crystal element that adjusts an amount of transmitted light according to an applied voltage (abstract and figures 1 – 2 item 31; liquid crystal dimming device). Regarding claim 11, as mentioned above in the discussion of claim 1, Kaifu teach all of the limitations of the parent claim. Additionally, Kaifu teaches an imaging apparatus (figure 1 image pickup unit 1) comprising: the dimming apparatus according to claim 1 (please look at claim 1 above); and an imaging element that captures an image of a subject to generate image data (figure 1 item 22; capture image). Allowable Subject Matter Claims 3 and 9 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: The following is a statement of reasons for the indication of allowable subject matter for claim 3: “wherein the controller sets a drive frequency of the drive voltage to be higher than a predetermined frequency when the exposure time is equal to or longer than a predetermined time, and sets the drive frequency to the predetermined frequency or less when the exposure time is shorter than the predetermined time” in combination with the other limitations in the claim and the parent claim is not discussed or suggested in any of the prior art that was searched. The following is a statement of reasons for the indication of allowable subject matter for claim 9: “wherein the controller determines an exposure time for a moving image and an exposure time for a still image, changes a drive frequency of the drive voltage according to a length of the exposure time for a moving image at a time of shooting a moving image, sets the drive frequency of the drive voltage to be higher than a predetermined frequency when the exposure time for a still image is equal to or longer than a predetermined time at a time of shooting a still image, and does not invert the drive voltage when the exposure time for a still image is shorter than the predetermined time” in combination with the other limitations in the claim and the parent claim is not discussed or suggested in any of the prior art that was searched. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. MORITA (US patent No. 20170108725) teaches a dimming element in image capture system. CHEN (US patent No. 20240272469) teaches a dimming element in image capture system. OOISHI (US patent No. 20240331651) teaches a dimming element in image capture system.
