Abstract

PURPOSE:To make a charge transfer element multipurpose, by using the charge transfer element as an image pickup element at an image pickup time and by using the charge transfer element as a temporary memory element at a signal reproducing time. CONSTITUTION:In case that charge transfer element 10 is used as an image pickup element, vertical shift register 2 becomes the image pickup part, and vertical shift register 3 becomes the storage part. At this time, a band-compressed signal can be obtained from terminal 5a by extending the clock period for read. In case that element 10 is used as a temporary memory elememt, registers 2 and 3 are used as the storage part. A band-compressed signal is supplied to terminal 1a of input register 1, and the period of write clocks is extended at this time, and next, written contents are transferred to register 3 and are read out by normal clocks thus obtaining the original band-expanded signal at terminal 5a.
