Abstract: When a signal output by a solid-state image sensing device is clamped to a predetermined reference potential, a high voltage generated in a transfer suspension period after the clamping as generally supplied to an A/D converter is generated. A sample/hold output Va is clamped to a clamp level Vref over a period of time between a halfway point of time of a signal of a picture element preceding ahead by one line and the end of an inhibit period of transfer clocks of a signal output by an empty transmission unit via a first clamp pulse and a sample/hold output for the second picture element, or a subsequent one of an OPB unit is clamped to the clamp level via a second clamp pulse to prevent a signal output from exceeding a reference voltage from being supplied to an A/D converter at a later stage.

Abstract: An adaptive peak value detector, wherein the peak value for a peak hold section is detected, the peak hold section being selected by a peak hold control circuit. A solid-state imaging sensor generates pixel signals representative of an image and the peak value of portions of the pixel signals is detected. The exposure time of the sensor is adjusted as a function of the detected peak value and auto-focusing of the image for the camera is carried out on the basis of the image received during the adjusted exposure time.
