Abstract
A pixel array including; color filter array (CFA) cells, each respectively including CFA blocks, each CFA block including color pixels, and the color pixels include a sub-block. The sub-block includes at least one first color pixel sensing a first color, at least one second color pixel sensing a second color different from the first color, and at least one third color pixel sensing a third color different from the first color and the second color.
Claims20
A pixel array comprising:
- color filter array (CFA) cells, each respectively including CFA blocks, each CFA block including color pixels, and the color pixels include a sub-block,
- wherein the sub-block includes at least one first color pixel sensing a first color, at least one second color pixel sensing a second color different from the first color, and at least one third color pixel sensing a third color different from the first color and the second color.
An image sensor comprising:
- a pixel array including color filter array (CFA) cells, each CFA cell including CFA blocks, each CFA block including color pixels, and color pixels of each CFA block including a sub-block, wherein the sub-block includes at least one first color pixel sensing a first color, at least one second color pixel sensing a second color different from the first color, and at least one third color pixel sensing a third color different from the first color and the second color;
- a row driver configured to generate control signals that control the generation of pixel signals by the color pixels of the pixel array;
- a read circuit configured to generate pixel data from the pixel signals;
- and
- a controller configured to control the row driver and the read circuit.
2 more elements
An image sensor pixel array, comprising:
- a plurality of color filter array (CFA) cells, each including a 2-by-2 arrangement of CFA blocks,
- wherein each CFA block includes color pixels having a same color arranged in a boundary region of the CFA block surrounding a sub-block, wherein the sub-block includes at least one first color pixel sensing a first color, at least one second color pixel sensing a second color different from the first color, and at least one third color pixel sensing a third color different from the first color and the second color.
