  • Transforming Light Signals Into Electric Signals (AREA)

Abstract

PURPOSE: To obtain a good reproduced picture suppressing a blooming phenomenon when the brightness of an object is fluctuated greatly, by controlling a photosensitive time and a transfer time automatically correspondingly to the light receiving quantity of a charge transfer element.
CONSTITUTION: In CCD1, signals which are transferred from photosensitive area 11 to accumulating area 12 in the first frame are led into read register 13 successively. Then, a part of this output is supplied to video averaging equipment 5, and the averaged video voltage of the output is compared with the reference voltage of reference voltage generator 7 by comparator 6, and the difference output is supplied to control signal generator circuit 8. Voltage control oscillator 81 leads out frequency signals proportional to the input level from comparator 6 and supplies them to frequency divider 82, counter 83, read clock generator 84, accumulating area clock generator 85 and photosensitive area gate generator 86. As a result, clocks and gate signals are supplied to CCD1, and a photosensitive time and a transfer time are controlled according to the light receiving quantity of CCD
