Object detection is performed for an image acquired by imaging using an array sensor in which a plurality of imaging elements are arranged one-dimensionally or two-dimensionally, some of the imaging elements are configured as color-filter-disposed pixels in which a color filter is disposed in an incident optical path, and color information acquisition points are formed by the color-filter-disposed pixels. Then, coloring processing in a pixel range of a detected object is performed by referring to color information acquired at the color information acquisition points corresponding to the inside of the pixel range of the detected object.

A lens unit (120) shows longitudinal chromatic aberration and focuses an imaged scene into a first image for the infrared range in a first focal plane and into a second image for the visible range in a second focal plane. An optical element (150) manipulates the modulation transfer function assigned to the first and second images to extend the depth of field. An image processing unit (200) may amplify a modulation transfer function contrast in the first and second images. A focal shift between the focal planes may be compensated for. While in conventional approaches for RGBIR sensors contemporaneously providing both a conventional and an infrared image of the same scene the infrared image is severely out of focus, the present approach provides extended depth of field imaging to rectify the problem of out-of-focus blur for infrared radiation. An imaging system can be realized without any apochromatic lens.
