Claim:
1. An image processor configured to compress image data and output compressed image data, the image processor comprising: a first compression circuit configured to generate compressed current data based on image data of a current frame, a second compression circuit configured to generate compressed previous data based on image data of a previous frame, a first uncompression circuit configured to generate decompressed current data based on the compressed current data; a second uncompression circuit configured to generate decompressed previous data based on the compressed previous data; an overdrive processing arithmetic circuit configured to generate overdriven data based on the decompressed current data and the decompressed previous data; a correction circuit configured to generate corrected overdriven data by correcting the overdriven data; a third compression circuit configured to generate compressed corrected overdriven data based on the corrected overdriven data; and a third uncompression circuit configured to generate decompressed corrected data based on the compressed corrected overdriven data; a transmission circuit configured to transmit the compressed corrected overdriven data according to a comparison result of the decompressed current data and the decompressed corrected data.
