Abstract
An image sensor supporting a normal sampling mode and a 1/N sampling mode for transmitting image data detected by a plurality of unit image sensors and stored in a plurality of latch circuits to a data processor using a plurality of transmission lines, wherein N is a natural number greater than 2, the image sensor including a horizontal address generator configured to generate horizontal addresses corresponding to addresses of the plurality of latch circuits, and to generate, based on the horizontal addresses, a first channel selection control signal and a second channel selection control signal of which activation times at least partially overlap.
Claims21
An image sensor supporting a normal sampling mode and a 1/N sub-sampling mode, the image sensor comprising:
- a sample and hold array including a plurality of latch circuits configured to store image data detected by a plurality of unit image sensors included in an image sensor array;
- a 2-channel transmission line block configured to connect image data output from the plurality of latch circuits to four transmission lines;
- and
- a horizontal address generator for generating a first channel selection control signal and a second channel selection control signal configured to control ON/OFF and ON/OFF times of a plurality of switches, according to a horizontal address corresponding to addresses of the plurality of latch circuits,
- wherein times during which the first channel selection control signal and the second channel selection control signal corresponding to the ON/OFF times of the switches are activated at least partially overlap, and N is a natural number greater than 2.
