The present disclosure relates to an imaging apparatus, an image sensor, and an image processor capable of reducing a load on an image processing unit related to image recognition processing.An imaging apparatus according to a first aspect of the present disclosure includes: an image sensor adapted to output image data including pixel signals generated in accordance with incident light by photoelectric conversion elements vertically and horizontally arranged on an imaging surface, adapted to divide the imaging surface into a plurality of areas, and adapted to generate image recognition support information for each of the areas on the basis of the pixel signals generated by the photoelectric conversion elements belonging to the area; and an image processing unit adapted to apply predetermined image processing to the image data output from image sensor by using the image processing support information output from the image sensor. The present disclosure is applicable to, for example, a camera having a face detection function.
