Title: Solid-state image pickup device provided with photometric function
Inventor: IMAI MASAHARU
IPC: H04N5/335
Filed: 1983-09-09
Abstract: PURPOSE:To make photometry of an incident image possible on the way of image pickup by repeating read of a signal for photometry during image pickup to operate an integrated value or a mean value or detect a maximum value, and stopping a reading means of the signal for photometry to read out a signal corresponding to the optical input of each picture element when this value reaches a prescribed value. CONSTITUTION:The output signal of a reading circuit 57 is applied only to odd- numbered picture elements to read non-destructively only these picture elements. This non- destructive read signal is processed by an integrating or averaging circuit 58, and its integrated value or mean value is always compared with a prescribed value by a comparison discriminating circuit 59. When non-destructive read of odd-numbered picture elements is repeated several times and it is discriminated by the circuit 59 that the integrated value or mean value reaches the prescribed value, a control signal is sent immediately from a control circuit 60 to a destructive reading circuit 53, and destructive read is performed. In this case, signals of all picture elements subjected to destructive read become image pickup information. Output signals obtained by non-destructive read preceding destructive read are used as a photometric signal of an image pickup array.

Abstract: PROBLEM TO BE SOLVED: To make it possible to make the frequencies and phases of a pixel clock and a sampling pulse coincident by forming a signal, of which the phase coincides with the phase of a clock synchronizing signal and of which the frequency is specified times the frequency thereof, to the sampling pulse. SOLUTION: A synchronizing signal processing circuit 7 forms and outputs the pixel synchronizing signal sampling pulse at the timing at which the pixel synchronizing signal Sp is sent from a computer 1 by counting the number of pulses of the horizontal synchronizing signal S2 after the vertical synchronizing signal S3 is sent thereto. A clock gate circuit 8 samples the pixel synchronizing signal Sp from a video signal S1 and sends this signal to a phase comparator 9 by allowing the passage of the video signal S1 when this pixel synchronizing signal sampling pulse is sent thereto. The phase comparator 9 compares the frequencies and phases of the output signal of a frequency divider 11 and the pixel synchronizing signal only when the pixel synchronizing signal sampling pulse is sent thereto. An S/H circuit 3 samples and holds the analog video signal S1 by its output signal.
