Abstract
An image pickup device is capable of picking up images while electrically enlarging the same. In enlarging image pickup, horizontal transfer pulses H.sub.1, H.sub.2, a reset pulse R, a clock signal CLK, sampling pulses SP.sub.1, SP.sub.2 and so on having the periods twice as long as those in the normal image pickup are generated from a horizontal transferring circuit in a timing pulse generating circuit. Thereby, charges stored in a CCD image sensor (6) are horizontally transferred by these signals. A vertical transfer circuit sets vertical transfer pulses V.sub.1 to V.sub.4 at arbitrary timings during 1H of a video period to output the same once in every 2H and outputs high speed vertical transfer pulses in two periods in a vertical blanking period and outputs a reading pulse TG between the first high speed vertical transfer period and the next high speed vertical transfer period. The charges stored in the CCD image sensor are then transferred in the vertical direction in response to these signals. Consequently, a selected area of the screen of the normal image pickup can be enlarged and picked up.
