ABSTRACT:
Correction tables store correction data. Based on the correction data, a linear interpolation circuit generates data in accordance with a data value of input image data. A latch circuit group latches each piece of output data of the linear interpolation circuit in synchronization with a rising edge of a block signal. A selector selects correction data based on an address signal and outputs the correction data to an adder circuit. The adder circuit adds delayed image data to the selected correction data, thus generating corrected image data. Accordingly, an error among channels, which is caused by phase expansion, can be corrected.
