Claim Text:
1. An imaging apparatus, comprising: an image sensor with a light receiving surface which includes two-dimensional arrays of at least three visible light pixels and an infrared pixel, the visible light pixels having sensitivity in different visible light wavelength ranges, the infrared pixel having sensitivity in the infrared wavelength range; a coded aperture which is disposed on the light receiving surface side of the image sensor and blocks, using a predetermined shape in a partial aperture area of a whole aperture area, light in one of the wavelength range in which the at least three visible light pixels have sensitivity and the wavelength range in which the infrared pixel has sensitivity, while directly transmitting light in the other wavelength range through the whole aperture area; and a processor for processing an image obtained by the image sensor, wherein the processor has a depth map generator for generating a depth map based on pixel signals obtained from the pixels, of one of the at least three visible light pixels and the infrared pixels, corresponding to the light in the one wavelength range which the partial aperture area of the coded aperture has blocked and the light which the coded aperture directly transmitted in an area other than the partial aperture area, and on the pixel signals obtained from the other pixels corresponding to the light in the other wavelength range which the whole aperture area of the coded aperture has directly transmitted, wherein the processor is further configured: to generate a blurred image as an interpolated image of the visible light image obtained through the visible light pixels, by using, as a reference image, an image obtained through the infrared pixel; and to generate, using the depth map, an image by changing the depth of field of the blurred image, and wherein the coded aperture acts on light in the wavelength range in which the infrared pixel has sensitivity.
