Patent ID: 8681251

Claim:
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 states and activation times of a plurality of switches, according to a horizontal address corresponding to addresses of the plurality of latch circuits, wherein: each of the latch circuits includes an output terminal connected to the four transmission lines via four switches, the first channel selection control signal controls the states of the switches for connecting two adjacent latch circuits, from among the plurality of latch circuits, to two of the four transmission lines, the second channel selection control signal controls the states of the switches for connecting two adjacent latch circuits adjacent to the latch circuits selected by the first channel selection control signal, from among the plurality of latch circuits, to the remaining two transmission lines, and times during which the first channel selection control signal and the second channel selection control signal corresponding to the activation times of the switches are activated at least partially overlap, and N is a natural number greater than 2.
