Document Type and Number:
Japanese Patent JP2512447
Kind Code:
B2
Abstract:
PURPOSE:To increase the saturated state of the photoelectric conversion of a solid-state image pick-up element by dividing one field period of a television signal mode into plural ones, accumulating one picture with a solid-state image pick-up element in respective time sections, adding the image output for plural pictures at the time of reading and converting it to the time base of one field. CONSTITUTION:To a solid-state image pick-up element 1, a clock pulse phi2f of a usual two-fold frequency is given from a clock pulse generating device 8, and a photoelectric converted picture element output is successively transferred from the solid-state image pick-up element 1 at the high speed of one picture (for one field) 1/120 seconds. A transferring output is sample-held by a sample holding circuit 2, and thereafter, the output is converted to the digital value by an A/D converter 3. To the sample holding circuit 2 and the A/D converter 3, the clock pulse phi2f is inputted. The image signal of two continuous screens (for one field) is distributed and written, further, reading is started by the same timing and the reading is completed in 1/60 seconds. The image signal from memories 4 and 5 is guided and added to an adder 6 during each reading.
