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 .
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 09/26/2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner.
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 (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 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.
Claims 1-9 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ishikawa et al.

Regarding claims 2 and 7, a point having the different type of color (i.e. blending coefficients) is a point that is different, by a predetermined threshold or more, in at least one of hue, saturation, or brightness from a point adjacent in the second direction (page 4, paragraph 0071, lines 5-7).
Regarding claims 3 and 8, a central side of the calibration image (Figure 4A, element 500b) has lower brightness than an outer side of the calibration image (Figure 4A, elements 500a and 500c).
Regarding claims 4 and 9, a projection device (Figure 2, element 100), comprising: an output image adjustment device (Figure 2, elements 116a, 116b and 116c) and an image creation unit (Figure 2, element 120) that creates the calibrated image (i.e. corrected image).
Regarding claim 5, an image adjustment method (i.e. DLP method; page 3, paragraph 0049, lines 2-3), comprising, by at least one processor (Figure 2, elements 114a, 114b and 114c): projecting, onto a projection target (Figure 3C, element 502), a calibration image including groups of points (i.e. corrected images; Figure 3C, elements 500a, 500b and 500c) representing coordinates (i.e. correction patterns) in a first direction (Figure 3B, element M) and a second direction (Figure 3B, element N) intersecting the first direction, each of the points having a same type of color as a point adjacent in the first direction and a different type of color from a point adjacent in the second direction (page 15, paragraph 0220, lines 2-6); capturing the calibration image projected onto the projection target (page 3, paragraph 0054, lines 1-3); and adjusting coordinates of a calibrated image (i.e. corrected image) to be projected based on captured image data (Figure 2, element 118) of the captured calibration image (i.e. corrected image).
Regarding claim 6, an output image adjustment device (Figure 2, elements 116a, 116b and 116c), comprising: a projection unit (Figure 2, elements 150a, 150b and 150c); an imaging unit (Figure 2, element 170) that captures the calibration image (i.e. corrected image) projected onto the projection target (Figure 3C, element 502); a memory (Figure 2, element 112); and at least one processor (Figure 2, elements 114a, 114b and 114c) coupled to the memory (Figure 2, element 112), wherein the at least one processor (Figure 2, elements 114a, 114b and 114c) is configured to: project, onto a projection target (Figure 3C, element 502) by the projection unit (Figure 2, elements 150a, 150b and 150c), a calibration image (i.e. corrected image) including groups of points (i.e. corrected images; Figure 3C, elements 500a, 500b and 500c) representing coordinates (i.e. correction patterns) in a first direction (Figure 3B, element M) and a second direction (Figure 3B, element N) intersecting the first direction, each of the points having a same type of color as a point adjacent in the first direction and a different type of color from a point adjacent in the second direction (page 15, paragraph 0220, lines 2-6), capture, by the imaging unit (Figure 2, element 160), the calibration image projected onto the projection target (page 3, paragraph 0054, lines 1-3); and adjust coordinates (i.e. correction patterns) of a calibrated image (i.e. corrected image), which is projected by the projection unit (Figure 2, elements 150a, 150b and 150c), based on captured image data (Figure 2, element 118) captured by the imaging unit (Figure 2, element 170).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Wu (US Pub. No. 2020/0244934 A1) discloses a projection system including a first projection device and a first image capturing device is provided. The first projection device projects a first projection image. The first projection image includes a plurality of different color lights and has color blocks of different brightnesses formed by the plurality of different color lights. The first image capturing device captures the first projection image to generate a first captured image. The first image capturing device includes a first processor. The first processor converts the first captured image into a first converted image according to a first conversion matrix. A color gradation adjustment operation is performed on the first converted image to output an adjustment signal, and the first projection device adjusts the projected first projection image according to the adjustment signal. An image color correction method is also provided.
Helt (US Pub. No. 2016/0165200 A1) teaches method for determining the operation of an image projector for projecting images onto a screen of a projection room. In particular, the method is implemented by computing means and comprises the following steps: driving the projector so as to project onto the screen a test card comprising a distribution of patterns of different hues, acquiring an image of the test card on the screen by a picture taking apparatus, and applying a processing of the image acquired, so as to determine at least one deviation of chrominance of the image acquired with respect to a predefined number of colors.
Kobayashi (US Pub. No. 2005/0243286 A1) shows an image processing system which can more exactly correct the distortion in an image by reducing the influence of color in an area onto which the image is projected, a projector is provided with a correction section which corrects image signals to adjust a distortion of an image; an image projection section which projects an image based on the image signals; a sensing section which senses the projected image to generate sensing information; a luminance-distribution analyzing section which generates coordinate information indicating a peak position which is the brightest position in the sensed projected image, based on the total luminance value for each pixel line forming the sensed projected image based on the sensing information; and a correction-amount deriving section which determines the distortion in the projected image and derives the amount of correction for the correcting section, based on the coordinate information.
