According to one embodiment, a camera module includes an image sensor, a main lens system and a sublens group. The sublens group is provided in an optical path between the main lens system and the image sensor. The sublens group forms an image piece for every pixel block. The image piece corresponds to a part of a subject image. The sublens group is integrated with a support structure. The support structure serves to support the sublens group above the image sensor.

An image recording device that records captured image data according to an embodiment of the present invention includes: an image sensor that acquires image data; a memory that holds measured PSF data indicating a PSF of at least one area of the image sensor virtually divided into a plurality of areas; and a restoring unit that restores the image data by using the measured PSF data. The measured PSF data is acquired from captured data acquired by capturing an adjustment chart for virtually dividing the image sensor into a plurality of areas by the image recording device.

According to one embodiment, an APC photodetector accepts a light beam branched from a light beam toward a recording medium by a branching mirror and detects intensity of a light beam supplied from a light source, a light quantity adjusting element adjusts the intensity of the light beam, and the intensity of the light beam incident to the APC photodetector is changed in a continuous manner or a stepwise manner by the light quantity adjusting element. Therefore, when the single APC photodetector detects recording and reproducing light beams, the recording and reproducing light beams can fall within a dynamic range of the APC photodetector.
