An object of the present invention is to provide an imaging apparatus capable of obtaining a sufficient resolution in a picture signal for zooming in on an output signal of an image pickup device by means of an electronic zoom process and a control method thereof. To attain this object, a timing generator generates a timing signal for controlling timing for reading charges to an image pickup device and the timing for mixing or transferring the charges. A zoom control portion determines a scaling factor for, by signal processing, expanding or reducing picture data generated based on the output signal of the image pickup device. The zoom control portion also determines the number of mixed pixels and a cutout range of the charges in the image pickup device. A vertical scaling factor control portion controls the timing generator so that mixture of the charges and charge transfer will be compliant with the number of mixed pixels and the cutout range respectively as determined by the zoom control portion.

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.
