Abstract
The present invention is directed to a terminal apparatus in which the in-frame compression factor of an image obtained by a camera is increased to restrict frame thinning when the camera is moved. A control circuit 60 performs control of a movable table 12. When a TV camera 10 is moved, the quantization table used in a quantization circuit 26 is changed over, whereby a higher compression factor of the coding conducted by a DCT circuit 24 and the quantization circuit 26 is achieved. Thus, a predetermined compression factor can be achieved without performing frame thinning.
