Solid-state image pickup device

Abstract

Abstract PURPOSE:To obtain still images and animations of good quality easily and stably by generating and storing a photoelectric charge corresponding to an optical image in photo sensors on odd and even lines simultaneously and transferring the photoelectric charge of each line to each vertical shift register simultaneously and taking out it with the first and the second horizontal shift registers to form and output a horizontal line signal of one frame. CONSTITUTION:The photoelectric charge corresponding to the optical image is generated and stored simultaneously in individual photo sensors 1 on odd and even lines corresponding to odd and even fields in a prescribed period TX in one frame and is transferred simultaneously to vertical shift registers 2. An odd line electric charge A out of the transferred electric charge is read out directly through the first horizontal shift register 3, and an even line electric charge B is stored and held temporarily in a storage register 6 after passing the first horizontal shift register 3 and is read out through the second horizontal shift register 7. As the result, the degradation of the image quality due to the deviation of exposure timing between odd and even fields is eliminated to obtain good still image.
