A detector includes a substrate; two first regions, each first region having a linear shape, and the two first regions being separated from each other on the substrate and arranged in parallel; and a pixel region provided between the two first regions and including a plurality of pixels, the pixel region including a plurality of second regions perpendicular to the two first regions, each of the two first regions including a peripheral circuit portion, each of the plurality of second regions including a driver line, and a width of each of the plurality of second regions being equal to or less than a width of a single pixel.
摘要:
Disclosed are an image sensor and a local binning method in which binning is applied selectively. For example, binning is applied to pixels having low illumination and binning is not applied to non-low illumination pixels. Information on pixels having low illumination for a first image frame may be stored and used to perform binning with respect to areas of a second image frame corresponding to low illumination pixel areas determined with respect to the first image frame.
