Patent number: 8983219Abstract: An image processing apparatus which re-encodes encoded data, encoded with a pixel block having a predetermined number of pixels as a coding unit, while suppressing degradation of image quality, with a higher compressibility. For this purpose, when an encoded-image-data input unit inputs JPEG encoded data with an 8×8 pixel block as a coding unit, a redundancy estimation unit performs encoding on the encoded data, and sets an encoded data amount obtained by the coding, as a target code amount for a recompressor to perform coding in accordance with JPEG 2000 coding. The inputted encoded data is decompressed by a decompressor, and the recompressor generates encoded data in the previously-determined target code amount. The code amount control is performed by deleting the encoded data in bit planes in an order from a least significant bit plane toward a high-order bit plane.Type: GrantFiled: January 31, 2012Date of Patent: March 17, 2015Assignee: Canon Kabushiki KaishaInventors: Hiroki Kishi, Yuki Shiraishi, Naoki Ito

Patent number: 8577096Abstract: An encoding apparatus encodes an image by tile in a smallest possible size while suppresses segmentation of a specific region in the image into tiles. Vertical lines at left and right ends of n-th face region are defined as boundary candidate vertical lines Lh(n) and Lm(n), and horizontal lines at upper and lower ends of the n-th region, as boundary candidate horizontal lines Lu(n) and Ls(n). A divider determines a horizontal line of another region existing within the range of the horizontal lines Lu(n) and Ls(n) of the n-th region as a line to be deleted. Further, the divider determines a vertical line of another region existing within the range of the vertical lines Lh(n) and Lm(n) as a line to be deleted. This processing is performed to the final region, then image data is divided using horizontal and vertical lines except the lines determined as lines to be deleted.Type: GrantFiled: December 9, 2009Date of Patent: November 5, 2013Assignee: Canon Kabushiki KaishaInventors: Yuki Shiraishi, Takeshi Yamazaki

Patent number: 8396308Abstract: Resolution interpolation data is generated by relatively simple processing. This enables image encoding by simple and quick processing to attain high image quality and high compression performance. To do this, a tile divider extracts tile data of 32×32 pixels from encoding target original image data. A resolution converter samples one pixel of a block of 2×2 pixels in the tile data, thereby generating reduced tile data of a reduced image. An interpolation data generator generates interpolation data to be used to generate tile data having the original resolution from the reduced tile data. Based on the interpolation data of a tile of interest, an encoding method selector outputs a control signal indicating which one of lossless encoding and lossy encoding should be executed for the reduced tile data. A code stream generator outputs the generated encoded data and interpolation data as encoded image data.Type: GrantFiled: November 17, 2009Date of Patent: March 12, 2013Assignee: Canon Kabushiki KaishaInventors: Hiroshi Kajiwara, Yuki Shiraishi, Naoki Ito, Hirokazu Tamura

Patent number: 8331705Abstract: This invention generates efficient encoded data to restore original image data from reduced image data. An input unit inputs block data of 2×2 pixels from original image data. A converter generates reduced image data having a size smaller than the original image data by sampling one pixel data at a preset position in the input block data. A generator generates encoded data to restore three non-sampling target pixel data in each block data so as to restore the original image data from the reduced image data generated by the resolution converter. To do this, the generator determines whether all non-sampling target pixels in a block of interest are restorable from a sampling target pixel in the block of interest or from sampling target pixels in three blocks adjacent to the block of interest, and generates and outputs three kinds of additional information based on the determination result.Type: GrantFiled: November 17, 2009Date of Patent: December 11, 2012Assignee: Canon Kabushiki KaishaInventors: Yuki Shiraishi, Hiroshi Kajiwara, Naoki Ito, Hirokazu Tamura
