Abstract
A The CMOS image sensor includes a pixel array including pixels arranged in a matrix of rows and columns and a row selection unit configured to generate selection signals for simultaneously or concurrently selecting at least two rows from the rows of the pixel array in response to a received row address. An analog-to-digital conversion unit is configured to convert pixel data output from the at least two rows selected from the pixel array into a digital video signal and output the digital video signal. The pixel array outputs the pixel data in response to the selection signals.

An image sensor comprising:
- a pixel array including a plurality of pixels arranged in a matrix of rows and columns;
- a row selection unit configured to generate selection signals for concurrently or simultaneously selecting at least two rows from the rows of the pixel array in response to a received row address;
- and
- an analog-to-digital conversion unit configured to convert pixel data output from the at least two rows selected from the pixel array into a digital video signal and output the digital video signal;
- wherein
- the pixel array outputs the pixel data in response to the selection signals.
