DRIVING CIRCUIT FOR SOLID-STATE IMAGE PICKUP ELEMENT AND ITS DRIVING METHOD

摘要

PURPOSE: To provide a driving circuit of a solid-state image pickup element and a driving method capable of projecting the information of the entire picture elements on the monitor of interlace without using an A/D converter or a frame memory or the like. CONSTITUTION: In this driving circuit 12 for driving the CCD solidstate image pickup element 11 of an entire picture element read system, in a first field, the signal charge of even numbered lines is read to a first horizontal transfer register 4 and the signal charge of odd numbered lines is read to a second horizontal transfer register 5 respectively. The vertical transfer clocksϕV1-ϕV3 of three phases for reading the signal charge of the odd numbered lines to the first horizontal transfer register 4 and reading the signal charge of the even numbered lines to the second horizontal transfer register 5 respectively in a second field are supplied to a vertical transfer register 2 and the lines (odd numbered / even numbered) of the signal charge to be read to the horizontal transfer registers 4 and 5 of two channels are switched for each exposure cycle (field).
