    摘要: An imaging apparatus restores a deteriorated image to a high-resolution image when the deteriorated image is restored based on a PSF image captured by an optical system. An imaging apparatus includes an optical system, and a PSF capturing unit that acquires point spread function (PSF) information captured by the optical system and outputs corrected PSF information. A subject capturing unit acquires subject information captured by the optical system and outputs the subject information; and an image restoration unit performs a restore operation for restoring the subject information, based on the corrected PSF information and the subject information. The PSF capturing unit subtracts a correction luminance value from the PSF information, and outputs the corrected PSF information. The correction luminance value is greater by a luminance value Is than a luminance value Nf of fixed value noise that does not fluctuate with time.

    摘要: A plurality of lenses 102a to 102d arranged in the same plane form a plurality of subject images on a plurality of imaging regions 104a to 104d. Vertical line directions and horizontal line directions of the pixel arrangement in the respective plurality of imaging regions are equal to one another among the plurality of imaging regions. Further, at least one pair of subject images received by at least one pair of imaging regions having a parallax in the vertical line (or horizontal line) direction among the plurality of imaging regions are shifted from each other by a predetermined amount in the horizontal line (or vertical line) direction. By performing pixel shifting in a direction perpendicular to the direction in which a parallax is generated, it always is possible to obtain a high-resolution image even when the subject distance varies.

    摘要: A plurality of imaging optical lenses (301a to 301c) form a plurality of subject images on a plurality of imaging regions (302a to 302c), respectively. When viewed along a direction parallel with optical axes, at least one straight line connecting corresponding points in at least one pair of the subject images that are formed by at least one pair of the imaging optical lenses is inclined with respect to a direction in which pixels are arranged in the imaging regions. In this way, a high-resolution image always can be obtained regardless of the subject distance.
