Kind Code:
B2
Abstract:
To provide a picture encoding device with high compression rate by always performing intra prediction and inter prediction in a direction with high prediction accuracy without changing a scanning direction, and provide a picture decoding device corresponding to the picture encoding device.SOLUTION: A picture decoding device 501 for decoding a signal of an encoded image includes: a mode determination unit 602 for determining whether or not a direction of an image was converted; a decoding unit 603 for decoding the image; and an image conversion unit 610 for performing conversion of the decoded image for recovering the determined conversion.SELECTED DRAWING: Figure 6
