Abstract
A signal processing apparatus according to an embodiment of the present invention includes: a compression processing unit that performs compression processing on n-bit data; a bit-number conversion unit that converts m-bit input image data into n-bit data (where n<m) by performing round-up or round-down processes on the lower (m−n) bits of the m-bit input image data, and feeds the obtained n-bit data to the compression processing unit; and a conversion processing control unit that selects either one of the round-up process and the round-down process to be performed on each datum of the n-bit data in accordance with a predefined rule on the basis of the position of a frame to which the datum belongs and the position in the frame at which the datum is located, and instructs the bit-number conversion unit to perform the selected round-up process or round-down process.
