Camera module and image recording method

摘要

According to one embodiment, a camera module includes a first sub-camera module, a second sub-camera module, and an imaging circuit serving as a position correcting unit. The position correcting unit corrects a position of an image at a cross point of imaging lenses. The position correcting unit corrects the position of the image acquired through the image-capture by the second sub-camera module.

1. An image recording method, comprising:
determining a distance to a subject that is a cross point of a first sub-camera module and a second sub-camera module; imaging an adjustment chart arranged on the cross point by the first sub-camera module and the second sub-camera module; generating a green image composed from a RAW image of the adjustment chart acquired from the first sub-camera module; generating a green image composed from a RAW image of the adjustment chart acquired from the second sub-camera module; calculating a correction coefficient used for a coordinate conversion of an image from the green image obtained from the second sub-camera module, wherein the green image acquired by the first sub-camera module is defined as a reference; executing a focus adjustment of a first imaging optical system provided to the first sub-camera module and a second imaging optical system provided to the second sub-camera module; and performing the coordinate conversion, using the correction coefficient, to the image acquired by the second sub-camera module, wherein a lens extended amount of a second imaging optical system is uniquely determined with a determination of a lens extended amount of the first imaging optical system.
