Title: Preamplifier for solid-state image pickup element
Inventor: FUSE SHOICHI
IPC: H04N5/335
Filed: 1991-08-22
Abstract: PURPOSE:To prevent the deterioration of a picture quality due to the asymmetry of signal edges, at the time of the rising and falling of a video signal. CONSTITUTION:In an image pickup device using the solid-state image pickup element, a preamplifier using a correlation duplex sampling method is used for removing a reset noise being a defect at the time of detecting a charge by a floating diffusion amplifier. The time constants of the charge and discharge of capacitors 24 and 31 of a clamp circuit and a sample-and-hold circuit are different, and then the signal edge at the time of the rising and falling of the video signal are asymmetrical, and as the result the picture signal deteriorates. Thus, a signal supply to the capacitors 24 and 31 is operated by using constant current circuits 45 and 50, so that the time constants of the charge and discharge of the capacitors 24 and 31 can be equal. Thus, the signal edges at the time of the rising and falling of the video signal can be symmetrical.
