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.

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.

摘要： A signal processing apparatus processes an image signal outputted from an image sensing device which has a plurality of photoelectric conversion elements covered with a color filter and which can be driven in a first reading method of separately reading signals from the respective photoelectric conversion elements and a second reading method of adding signals generated by the photoelectric conversion elements by at least two signals corresponding to the photoelectric conversion elements of a same color then outputting the added signals. The signal processing apparatus comprises a switch that switches between the first reading method and the second reading method, and a correction unit that passes signals inputted from the image sensing device without correcting positions of barycenters of the inputted signals when the first reading method is set, and corrects positions of barycenters of the inputted signals when the second reading method is set.
