摘要

A video encoding device includes an intra prediction unit for performing intra prediction on an image, a frequency transform/quantization unit for frequency transform and quantizing a prediction error based on the intra prediction performed by the intra prediction unit, an entropy encoding unit for entropy-encoding a transform quantization value generated by the frequency transform/quantization unit, an edge detection unit for detecting edge information on an image block of the minimum frequency-transform block size of the image, and edge information storage unit for storing the edge information detected by the edge detection unit.
