Abstract
According to one embodiment, a camera module includes a plurality of sub-camera modules. The sub-camera modules include imaging elements and imaging lenses. At least two of the sub-camera modules include the imaging lenses, subject distances of which when best-focused are set different from each other.
Claims19
A camera module comprising:
- a plurality of sub-camera modules including imaging elements that pick up subject images and imaging lenses that make light captured from a subject incident on the imaging elements;
- a resolution restoring unit that carries out resolution restoration processing for the subject images;
- a subject-distance estimating unit that estimates subject distances of the subject images;
- and
- a matrix selecting unit that selects a deconvolution matrix based on the subject distances estimated by the subject-distance estimating unit, wherein
- at least two of the sub-camera modules include the imaging lenses, subject distances of which when best-focused are set different from each other, the subject distances being distances between the sub-camera modules and the subject, and
- the resolution restoring unit carries out, based on the deconvolution matrix selected by the matrix selecting unit, the resolution restoration processing for each of image data obtained by the sub-camera modules.

An image processing apparatus comprising:
- a resolution restoring unit that carries out resolution restoration processing for subject images picked up by a plurality of sub-camera modules;
- a subject-distance estimating unit that estimates subject distances between the sub-camera modules and a subject;
- and
- a matrix selecting unit that selects a deconvolution matrix based on the subject distances estimated by the subject-distance estimating unit, wherein
- the resolution restoring unit carries out, based on the deconvolution matrix selected by the matrix selecting unit, the resolution restoration processing for each of image data obtained by the sub-camera modules.

An image recording method comprising:
- picking up subject images with a plurality of sub-camera modules including at least two sub-camera modules, subject distances of which when best-focused are set different from each other, the subject distances being distances between the sub-camera modules and a subject;
- carrying out resolution restoration processing for the subject images;
- estimating the subject distances of the subject images;
- selecting a deconvolution matrix based on the estimated subject distances;
- and
- carrying out, based on the selected deconvolution matrix, the resolution restoration processing for each of image data obtained by the sub-camera modules.
