Zusammenfassung: | PURPOSE: To provide an image encoder which decreases the code quantity of an encoding system for a moving picture and a still picture and shortens the arithmetic time by omitting encoded data by utilizing characteristics of the eyes of a human. CONSTITUTION: A feature extracting means 3 extracts features of an image from the luminance component of input image data. When one of a high- luminance, a low-luminance, and a high-frequency component is detected, (c) terminals as movable terminals of a 1st decision means 5, a 2nd decision means 8, a 3rd decision means 11, and a 4th decision means 14 consisting of switch means are connected to (a) terminals where no arithmetic operation is performed at the time of the arithmetic operation for color components and zero is inputted from a terminal 9 for zero input to omit encoding arithmetic operation for the color components, thereby shortening the arithmetic operation time and decreasing the code quantity. |
