Title: Solid-state image pickup device
Inventor: TAKAI TSUTOMU
IPC: H04N5/353
Filed: 1990-08-27
Abstract: PURPOSE:To obtain a video signal having quality capable of being reproduced as a picture even when a dark object with deficient luminous quantity is picked up by controlling automatically an exposure time of an image pickup element in addition to the iris control of a lens. CONSTITUTION:A luminance level detection circuit 15 monitors a level of a luminance signal outputted from a D/A converter circuit 9 and it is informed to an exposure time control circuit 14. The exposure time control circuit 14 controls a CCD drive circuit 12 when a level of a luminance signal reaches a prescribed level or below to vary an output interval of a field shift pulse in response to the level of a luminance signal Y and opens the iris of a lens 1 via an iris control circuit 13. However, when the output interval of the field shift pulse is set longer, since the output interval differs from the normal interval, a signal stored in a memory circuit 8 is used to interpolate the original signal while the output signal is not obtained.

IPC: H04N5/14
Filed: 1990-08-28
Abstract: PURPOSE:To realize the peak detection which has a high accuracy by this discovery by comparing an input voltage with the hold voltage of a hold capacitor, and charging the capacitor when the hold voltage doesn't get to the input voltage according b a peak to be detected is a maximum value or a minimum value. CONSTITUTION:A hold capacitor 1 is charged by currents supplied from a current source 3. The hold voltage of the capacitor 1 is outputted through a buffer circuit 4, and applied to the negative input terminal of a comparator 2. On the other hand, the input voltage is clamped by a clamp circuit 6 so that the reference level can be a prescribed level, and applied to the positive input terminal of the comparator 2. The comparator 2 turns the current source 3 into an active state when the input voltage is larger than the hold voltage of the capacitor 1 in order to charge the capacitor 1. When the hold voltage comes to be equal to the input voltage by the charge to the capacitor 1, the current source 3 stops the supply of the currents.
