Document Type and Number:
Japanese Patent JP2916620
Kind Code:
B1
Abstract:
An image sensor with sampling control system including a sensor unit 1 having a number of pixel circuits arranged in matrix, a memory unit 2 having a number of memory circuits 12 arranged in matrix, each memory circuits being corresponding to respective pixel circuits, a first horizontal shift register 9 writing a pixel read-out pattern into said memory circuits in accordance with an externally supplied sample selection signal, a first vertical shift register 8 for generating signals for writing and reading said pixel read-out pattern into and out of said memory circuits, a second vertical shift register 7 driven in synchronism with said first vertical shift register 8 for supplying a pixel value read-out signal to said pixels circuits, a second horizontal shift register 3 for outputting pixel values selected in accordance with the pixel read-out pattern, a third horizontal shift register 4 for outputting all pixel values, and a switch unit 6 for selectively reading the pixel values out of any one of said second and third horizontal shift registers in accordance with a node signal.
