Patent ID: 7412079

Claim:
An image processing apparatus comprising: input means for inputting a moving image signal; extracting means for extracting a portion of the moving image signal for a plurality of frames input by the input means; encoding means for encoding the portion of the moving image signal extracted by the extracting means using intraframe coding and interframe predictive coding; and control means for detecting motion of an image in an area outside the portion of the moving image signal input by the input means and for controlling a time for performing encoding using the intraframe coding performed by the encoding means in accordance with a result of detection of the motion, wherein the control means detects that the image in the area outside the portion in a present frame moves inside the portion in a consecutively following frame; and wherein the control means controls the encoding means to encode the image signal in the present frame using the interframe predictive coding and to encode the image signal in the consecutively following frame using the intraframe coding.
