There is provided a transmitter which is capable of compressing incoming image with a relatively small delay time and transmitting the compressed image data to a receiver. Image data TD contains at least i pixel values of pixels arranged in line along a single direction, each pixel value being expressed in n bits. A transmitter Tx for compressing such image data and transmitting the image data to a receiver Rx via a transmission path N comprises a blocking section 1, a data compression section 2, and a data sending section 3. The blocking section 1 takes every p pixel values among the i pixel values in the image data to form a data block, and sequentially outputs a plurality of said data blocks DB each including the p pixel values. The data compression section 2 reduces an amount of data from each data block DB outputted from the blocking section 1 and thereby outputs a compressed block CBr. The data sending section 3 sends the compressed block CBr outputted from the data compression section 2 onto the transmission path N.
