ABSTRACT:
The amount of edge enhancement outputted from an amount-of-edge-enhancement computing circuit is determined on the basis of the degree of sharpness of the edge independently of a zoom magnification. In the meantime, in an enhancement coefficient computing circuit, an enhancement coefficient according to the zoom magnification is computed. In a multiplier, the output from the amount-of-edge-enhancement computing circuit (the amount of edge enhancement) is multiplied by the output from the enhancement coefficient computing circuit (the enhancement coefficient). The resultant amount of edge correction is outputted from the multiplier. Accordingly, the amount of edge correction outputted from the multiplier takes a value according to the zoom magnification. According to this arrangement, enhancement processing which does not bring about overcorrection or unprocessing can be applied to the edge portion of an image enlarged by electronic zoom. In consequence, it is possible to enhance the apparent resolution of the image enlarged by electronic zoom.
