Abstract
An imaging device that includes a first color filter, a second color filer and an image sensor. The first color filter includes a first plurality of color filter regions that transmit a color of a first set of colors. The second color filter includes that transmit a color of a second set of colors. The second set of colors is different from the first set of colors. The image sensor detects light that passes through both the first color filter and the second color filter and generates an image signal.
Claims15
An imaging device comprising:
- a first color filter configured to receive light and transmit a first portion of the light, the first color filter comprising a first plurality of color filter regions, wherein each color filter region of the first plurality of color filter regions transmits a color of a first set of colors;
- a second color filter configured to receive the first portion of the light transmitted through the first color filter and transmit a second portion of the light, the second color filter comprising a second plurality of color filter regions, wherein each color filter region of the second plurality of color filter regions transmits a color of a second set of colors, wherein all the colors of the second set of colors are different from all the colors of the first set of colors;
- and
- an image sensor configured to detect the second portion of the light transmitted through the second color filter and to generate an image signal, wherein the first color filter comprises cyan, magenta, yellow and white color filter regions of equal areas, and wherein the second color filter comprises red, blue, green and infrared color filter regions.
