27. An image sensor comprising light-sensitive pixels including color pixels and monochrome pixels covering an area of the image sensor, wherein:
-
the color pixels include first color pixels that are color-coded to be sensitive to a first color, and second color pixels that are color-coded to be sensitive to a second color different from the first color, the monochrome pixels are not color-coded, the light-sensitive pixels are arranged in a checkerboard pattern in which the color pixels alternate with the monochrome pixels in each row along a row direction and in each column along a column direction, and in which the first color pixels alternate with the second color pixels in two diagonal directions that extend obliquely to the row direction and the column direction, and the first color and the second color are red and green respectively, or red and yellow respectively, or yellow and blue respectively, or yellow and green respectively, or green and blue respectively. - View Dependent Claims (28)
