Abstract
An image encoding apparatus includes a compressor that generates a bitstream including encoded data corresponding to values of original pixels, based on one of encoding modes, and a reconstructor that generates values of reference pixels by reconstructing the bitstream. In a first mode of the encoding modes, the compressor generates the bitstream based on a difference value between each of the values of the original pixels and a reference value which is based on at least one of the values of the reference pixels. In a second mode of the encoding modes, the compressor generates the bitstream based on an average value of at least two of the values of the original pixels.
