ABSTRACT:
An interpolation calculation circuit for improving the image quality for recording and display is provided. The interpolation calculation circuit interpolates a necessary pixel on the basis of interpolation calculation (cubic interpolation processing) by an approximate expression of an interpolation coefficient of at least 3rd-order. This cubic interpolation processing is applied to basic processing of an electronic camera, i.e., 3-CCD processing, format conversion, and image enlargement/reduction. In consideration of the operation load on the electronic camera, cubic interpolation processing is performed in accordance with the image sensing mode or the like only when it is necessary, thereby controlling whether execution of interpolation processing is enabled/disabled.
