Abstract: A temperature detector configured for use in a mobile terminal includes a lens, a collimator hole, and an infrared sensor that are arranged on an optical path. The lens is configured to converge ambient light, and the ambient light includes target area light and another area light. The collimator hole is used to obtain the target area light by screening and block the other area light. That is, the collimator hole screens the incident ambient light, and allows only the target area light to reach the infrared sensor.

Abstract: This application discloses an image sensor, which includes a color film layer. The color film layer includes a plurality of color film units, the color film unit includes at least one color-determined subunit and at least three transparent subunits, and a color of the color-determined subunit is determined. The color-determined subunit is configured to filter out a portion of the received light, and the transparent subunit is configured to allow light to pass through. A ratio of a quantity of the at least one color-determined subunit to a quantity of the plurality of subunits is less than 1/2. Because the transparent subunit can allow light to pass through, and most of light incident to the color film layer can be received by a photodiode, light sensitivity of the image sensor can be effectively increased without increasing an area of the color film layer or increasing a size of the photodiode.
