Patent ID: 8854513

Claim:
An imaging device comprising: a first imaging element configured to receive a first image light component and output a first color electric signal; a second imaging element configured to receive a second image light component and output a second color electric signal; a third imaging element configured to receive a third image light component and output a third color electric signal; a first gain controller including a first thermistor to vary a first output from the first gain controller, the first gain controller configured to vary a first gain of the first color electric signal in accordance with variations of a temperature of the first imaging element and an ambient temperature; and a second gain controller including a second thermistor to vary a second output from the second gain controller, the second gain controller configured to vary a second gain of the second color electric signal in accordance with variations of a temperature of the second imaging element and the ambient temperature, wherein a number of times the third image light component is reflected by a prism to the third imaging element is less than a number of times the first image light component and second image light component are reflected by the prism to the first imaging element and the second imaging element respectively, and wherein the first imaging element is a sensor to receive the first image light component, the second imaging element is a sensor to receive the second image light component and the third imaging element is a sensor to receive the third image light component being a green image component.
