摘要： 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.

A display is provided for simultaneously displaying at least a part of a video image which corresponds to the first video signal, and also for displaying a state of the multiplexing operation being performed by the multiplexing circuitry under the control of the control circuitry. Preferably, only a peripheral portion of the image is faded in the view finder. Alternatively, a bar graph on the side of the image in the view finder indicates the degree of fading the image is subjected to.

摘要： An image pickup apparatus including a photoelectric conversion element, first, a shutter speed for still-image pickup is set. Next, an image-pickup frame rate is set on the basis of the shutter speed for still-image pickup. Then, an operation of the photoelectric conversion element is controlled such that picked-up images are output at the set image-pickup frame rate. When the image-pickup frame rate that is set is higher than a moving-image-reproducing frame rate, a frame for use in a moving-image reproduction is generated from a plurality of frames of the picked-up images and reproduction is performed at the moving-image-reproduction frame rate.
