Abstract
An image sensor capable of canceling crosstalk without reduction of a signal to noise ratio (SNR) to improve a sensitivity includes a plurality of light detection units and a filter array including a plurality of filters, with each of the plurality of filters being deposited on a corresponding one of the light detection units. The filter array includes a green filter used to transmit a green component of an incident light, a yellow filter used to transmit a yellow component of the incident light, and a cyan filter used to transmit a cyan component of the incident light.
Claims9
An image sensor comprising:
- a plurality of light detection units;
- and
- a filter array including a plurality of filters, each of the plurality of filters being deposited on a corresponding one of the light detection units,
- wherein the filter array comprises:
- a green filter used to transmit a green component of an incident light;
- a yellow filter used to transmit a yellow component of the incident light;
- and
- a cyan filter used to transmit a cyan component of the incident light.
An image sensor comprising:
- a plurality of light detection units which includes a green detection unit having a green pixel, a yellow detection unit having a yellow pixel, a cyan detection unit having a cyan pixel, a first white detection unit having a first white pixel and a second white detection unit having a second white pixel;
- a filter array including a plurality of filters, each of the plurality of filters being deposited on a corresponding one of the light detection units,
- wherein the filter array comprises:
- a green filter used to transmit a green component of an incident light;
- a yellow filter used to transmit a yellow component of the incident light;
- a cyan filter used to transmit a cyan component of the incident light.
- a first white filter used to transmit the incident light;
- and
- a second white filter used to transmit the incident light;
- and
- an operation unit, wherein the operation unit comprises a red signal operation unit which generates a red signal where cross-talk is canceled, a blue signal operation unit which generates a blue signal where cross-talk is canceled and a green signal operation unit which outputs a green signal from an electrical signal output from the green pixel.
