Abstract:
1. An image sensor, comprising: a sensing device including a pixel array having a plurality of unit pixels, the sensing device being configured to generate pixel data in response to an incident light signal having information of an image of an object and information of an ambient light; an image data generation unit configured to generate image data corresponding to the object based on the pixel data; and an illuminance data generation unit configured to generate illuminance data corresponding to the ambient light based on the pixel data, the plurality of pixels including first pixels, the pixel data including first data generated based on light incident on the first pixels, both the image data and the illuminance data being generated based on the first data, wherein the pixel array includes a plurality of ambient light sensing units each of which includes at least two adjacent unit pixels among the plurality of unit pixels, wherein the illuminance data generation unit is configured to select effective sensing units among the plurality of ambient light sensing units by performing a crop operation and a sub-sampling operation on the pixel array, and configured to generate the illuminance data based on effective pixel data, which correspond to the effective sensing units, among the pixel data, and wherein the illuminance data generation unit includes, the sensing device being configured to control an exposure time of the plurality of unit pixels based on the exposure control signal.
