Abstract
An image encoding apparatus includes an input unit that receives image data; a prediction unit that calculates a predicted pixel value of a pixel of interest to be processed in the image data; a prediction error calculating unit that calculates a prediction error value by using an actual pixel value and the predicted pixel value of the pixel of interest; a main encoder that encodes the prediction error value with information including a number of bits and an error value, the main encoder encoding, as the error value, only one or more most significant bits corresponding to a number of effective bits when the number of bits exceeds the number of effective bits; and an additional encoder that encodes one or more least significant bits of the prediction error value, excluding the one or more most significant bits corresponding to the number of effective bits, as an additional error value.
