Electronic apparatus, and method and computer-readable medium for the same

Abstract

An electronic apparatus including an input unit configured to separate image data into pixel blocks and serially input luminance data and color difference data of each pixel block as individual pieces of block data, respectively, a quantization unit configured to serially convert each piece of the block data into quantized data, an encoding unit configured to serially convert each piece of the quantized data into encoded data, a color generation unit configured to generate compressed color image data using the encoded data, and a monochrome generation unit configured to generate compressed monochrome image data using the encoded data by performing one of deleting particular pieces of encoded data corresponding to the color difference data from a data sequence of the encoded data generated through the conversion by the encoding unit, and replacing the particular pieces of encoded data with encoded data corresponding to monochrome color difference data.
