Abstract
An image sensor includes multiple pixel groups arranged in a row included in a pixel array, the row including multiple pixels respectively allocated to the multiple pixel groups. The image sensor further includes multiple row drivers configured to respectively control operations of the pixels respectively allocated to the pixel groups in the row, and multiple readout circuits configured to respectively read out pixel signals output by the pixels respectively allocated to the pixel groups in the row.
Claims17
An image sensor comprising:
- a plurality of pixel groups arranged in a plurality of rows included in a pixel array, the pixel array comprising a plurality of pixels respectively allocated to the plurality of pixel groups;
- a plurality of row drivers configured to respectively control operations of the plurality of pixels respectively allocated to the plurality of pixel groups in the row, wherein each pixel group of the plurality of pixel groups connects to one corresponding row driver of the plurality of row drivers;
- and
- a plurality of readout circuits configured to respectively read out pixel signals output by the plurality of pixels respectively allocated to the plurality of pixel groups in each of the plurality of rows,
- wherein the plurality of row drivers are further configured to respectively generate corresponding row control signals to control operations for controlling pixels included in each row among the plurality of rows, and
- wherein the plurality of row drivers are activated at different frames to control operations of corresponding pixels.
