3. The apparatus according to claim 1, wherein the target code amount results from subtraction of the second code amount from a code amount assigned to the process unit.
4. The apparatus according to claim 1, wherein the first encoder predictively encodes a pixel to be encoded based on a pixel adjacent to the pixel to be encoded.
5. The apparatus according to claim 1, wherein the output selector outputs flag information indicative of whether to output the encoding result from the first encoder or the encoding result from the second encoder before outputting an encoding result for the second pixel group.
6. The apparatus according to claim 4, wherein, for a pixel adjacent to a process unit next to a current process unit, a first reference pixel based on the encoding result from the first encoder coincides with a second reference pixel based on the encoding result from the second encoder.
