Encoding apparatus and encoding method

摘要

An encoding apparatus includes an encoding unit that encodes an image to be encoded; a generating unit that generates a local decoded image from the encoded image; a difference calculation unit that calculates difference values between pixels included in the local decoded image and pixels included in the image to be encoded; and a modifying unit that determines pixels from the local decoded image based on the difference values, and modifies the determined pixels.

1. An encoding apparatus comprising:
a processor; and a memory storing a program which, when executed by the processor, causes the encoding apparatus to: encode an image to be encoded; generate a local decoded image from the encoded image; calculate difference values between pixels included in the local decoded image and pixels included in the image to be encoded; select one of the calculated difference values, wherein the selected difference value is a value which is most frequent in the calculated difference values; and correct each pixel of the local decoded image based on the selected difference value.
