20100124380 | IMAGE ENCODING APPARATUS AND METHOD OF CONTROLLING THE SAME - 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. | 05-20-2010 |

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. | 06-10-2010 |
