Abstract:
1. An area sensor which detects color information and an input position of visible light by sensing an input image of the visible light on a detection target surface, said area sensor comprising: at least one first sensor which includes a first light sensor element configured to sense an intensity of light of a first combination of two primary colors from among red, blue, and green; at least one second sensor which includes a second light sensor element configured to sense an intensity of light of a second combination of two primary colors from among red, blue, and green, the two primary colors being different from the two primary colors constituting the first combination; a position detecting section configured to detect color information and an input position of visible light by causing the at least one first sensor and the at least one second sensor to sense respective input images of the visible light on a detection target surface; and three color filters which are a red color filter, a blue color filter, and a green color filter, wherein the first light sensor element includes an optical filter which blocks visible light and includes a color filter from among the three color filters, and the color filter transmits light of a first primary color which is other than the two primary colors constituting the first combination, and the second light sensor element includes an optical filter which blocks visible light and includes a color filter from among the three color filters, and the color filter transmits light of a second primary color which is other than the two primary colors constituting the second combination.
