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.
Claims 1, 6-7, and 12 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chang (US Pub. 20160360198 A1).
Regarding claim 1, Chang discloses an image processing device comprising: circuity configured to (Chang; Fig. 7, Para. [0077]. A video processing system/method is used for video coding.):
parse size identification data from a bitstream to identify whether a maximum block size of an orthogonal transform block is 64 or 32 (Chang; Para. [0077-78]. Size data from a bitstream is determined/parsed to determine a maximum block size of transform block being 64 or 3, also see Para. [0033].);
on condition that the size identification data parsed indicates the maximum block size of the orthogonal transform block is 32, generate a residual signal by applying inverse orthogonal transformation processing to transform coefficients obtained by decoding the bitstream according to identification data that identifies whether adaptive color conversion processing for adaptively converting a color space of the image or inverse adaptive color conversion processing for adaptively reversing the color space of the image is enabled (Chang; Para. [0077-78]. For size data determined indicating a maximum block size of a transform block being 32, a residual block is generated by using inverse transform processing to coefficients from bitstream decoding in accordance with size information indicating whether ACT processing or inverse ACT processing is enabled or not, also see Para. [0059-60].); and
apply inverse adaptive color conversion processing to the residual signal (Chang; Para. [0077-78]. Inverse adaptive color transform is used for residual blocks.).
Claim 6 is directed to an image processing method, comprising a sequence of processing steps corresponding to the same as claimed in claim 1, and is rejected for the same reason of anticipation as outlined above.
Regarding claim 7, Chang discloses an image processing device comprising: circuity configured to (Chang; Para. [0107-108]. A video processing system includes circuitry for video coding.):
identify whether adaptive color conversion processing for adaptively converting a color space of the image or inverse adaptive color conversion processing for adaptively reversing the color space of the image is enabled, only when a size identification data identifies that 32 is applied as a maximum block size of an orthogonal transform block (Chang; Para. [0077-78]. For size data indicating 32 being used as a max block size of a transform block, adaptive color transforming or inverse adaptive color transforming for a color space is determined to be used or not.); and
encoding the image to generate a bitstream containing the identification data (Chang; Para. [0077-78]. Images are encoded to generate a bitstream including identification data.).
Regarding claim 12, Chang discloses an image processing method, comprising (Chang; Para. [0107-108]. A video processing system includes circuitry for video coding.):
determining whether a size identification data identifies that 32 is applied as a maximum block size of an orthogonal transform block; and
in response to 32 bring applied as the maximum block size of the orthogonal transform bloc, identify whether adaptive color conversion processing for adaptively converting a color space of the image or inverse adaptive color conversion processing for adaptively reversing the color space of the image is enabled (Chang; Para. [0077-78]. For size data indicating 32 being used as a max block size of a transform block, adaptive color transforming or inverse adaptive color transforming for a color space is determined to be used or not.); and
encoding the image to generate a bitstream containing the identification data (Chang; Para. [0077-78]. Images are encoded to generate a bitstream including identification data.).
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 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 2-5 and 8-11 are rejected under 35 U.S.C. 103 as being unpatentable over Chang (US Pub. 20160360198 A1) in view of Ko (US Pub. 20220141465 A1).
Regarding claim 2, Chang discloses the size identification data (Chang; See remarks regarding claim 1 above.).
But it does not specifically disclose the size identification data is set as a sequence parameter set of the bitstream.
However, Ko teaches the size identification data is set as a sequence parameter set of the bitstream (Ko; Para. [0198-199]. Size data is set as a sequence parameter set of a bitstream.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to modify the video processing system of Chang to adapt a signaling approach for transform block size, by incorporating Ko’s teaching wherein parameters on the sequence parameter set level are used to signal transform information, for the motivation to signal present conditions pertaining to a color component of transform blocks (Ko; Abstract.).
Regarding claim 3, while Chang is silent, Ko teaches the size identification data is set as a syntax of sps_max_luma_transform_size_64_flag (Ko; Para. [0198-199]. Syntax elements, e.g. sps_max_luma_transform_size_64_flag, is used.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to modify the video processing system of Chang to adapt a signaling approach for transform block size, by incorporating Ko’s teaching wherein parameters on the sequence parameter set level are used to signal transform information, for the motivation to signal present conditions pertaining to a color component of transform blocks (Ko; Abstract.).
Regarding claim 4, while Chang is silent, Ko teaches the identification data is referenced only when a value of sps_max_luma_transform_size_64_flag is set to 0 (Ko; Para. [0264, 266-26]. An identification data is used for sps_max_luma_transform_size_64_flag being 0.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to modify the video processing system of Chang to adapt a signaling approach for transform block size, by incorporating Ko’s teaching wherein parameters on the sequence parameter set level are used to signal transform information, for the motivation to signal present conditions pertaining to a color component of transform blocks (Ko; Abstract.).
Regarding claim 5, while Chang is silent, Ko teaches arithmetically decode the bitstream to generate quantized transform coefficients (Ko; Para. [0087-88]. A bitstream is arithmetically decoded to generate quantized transform coefficients. Chang; Para. [0055-59]. A bitstream is arithmetically decoded to generate quantized transform coefficients.); and
inversely quantize the quantized transform coefficients to generate the transform coefficients (Ko; Para. [0087-88]. Quantized transform coefficients are inversely quantized to generate transform coefficients. Chang; Para. [0055-59]. A bitstream is arithmetically decoded to generate quantized transform coefficients.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to modify the video processing system of Chang to adapt a processing approach for transform block, by incorporating Ko’s teaching wherein quantization and entropy coding is performed, for the motivation to signal present conditions pertaining to a color component of transform blocks (Ko; Abstract.).
Regarding claim 8, Chang discloses the size identification data (Chang; See remarks regarding claim 1 above.).
But it does not specifically disclose the circuitry is configured to set the size identification data as a sequence parameter set of the bitstream.
However, Ko teaches the circuitry is configured to set the size identification data as a sequence parameter set of the bitstream (Ko; Para. [0198-199]. Size data is set as a sequence parameter set of a bitstream.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to modify the video processing system of Chang to adapt a signaling approach for transform block size, by incorporating Ko’s teaching wherein parameters on the sequence parameter set level are used to signal transform information, for the motivation to signal present conditions pertaining to a color component of transform blocks (Ko; Abstract.).
Regarding claim 9, while Chang is silent, Ko teaches the circuity is configured to set the size identification data as syntax of sps_max_luma_transform_size_64_flag (Ko; Para. [0198-199]. Syntax elements, e.g. sps_max_luma_transform_size_64_flag, is used.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to modify the video processing system of Chang to adapt a signaling approach for transform block size, by incorporating Ko’s teaching wherein parameters on the sequence parameter set level are used to signal transform information, for the motivation to signal present conditions pertaining to a color component of transform blocks (Ko; Abstract.).
Regarding claim 10, while Chang is silent, Ko teaches the circuity is configured to set the identification data only when a value of sps_max_luma_transform_size_64_flag is set to 0 (Ko; Para. [0264, 266-26]. An identification data is used for sps_max_luma_transform_size_64_flag being 0.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to modify the video processing system of Chang to adapt a signaling approach for transform block size, by incorporating Ko’s teaching wherein parameters on the sequence parameter set level are used to signal transform information, for the motivation to signal present conditions pertaining to a color component of transform blocks (Ko; Abstract.).
Regarding claim 11, while Chang is silent, Ko teaches the circuity is further configured to: apply orthogonal transformation processing to a residual signal for each orthogonal transform block as a processing unit (Ko; Para. [0087-88]. Transform processing is used for a residual block for each transform block. Chang; Para. [0055-59]. Transform processing is used for a residual block for each transform block.);
quantize transform coefficients to generate quantized transform coefficients (Ko; Para. [0087-88]. Transform coefficients are quantized to generate quantized transform coefficients. Chang; Para. [0055-59]. Transform coefficients are quantized to generate quantized transform coefficients.); and
arithmetically encodes the quantized coefficients to generate the bitstream (Ko; Para. [0087-88]. Quantized coefficients are arithmetically encoded to generate a bitstream. Chang; Para. [0055-59]. Quantized coefficients are arithmetically encoded to generate a bitstream.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to modify the video processing system of Chang to adapt a processing approach for transform block, by incorporating Ko’s teaching wherein quantization and entropy coding is performed, for the motivation to signal present conditions pertaining to a color component of transform blocks (Ko; Abstract.).
