MONOCULAR 3D-IMAGING DEVICE, SHADING CORRECTION METHOD FOR MONOCULAR 3D-IMAGING DEVICE, AND PROGRAM FOR MONOCULAR 3D-IMAGING DEVICE

摘要

Shading characteristics unique to a monocular 3D-imaging device can be corrected. A focal length is obtained (step S11), and a table that corresponds to the focal length is obtained (steps S12, S13, S14...) from a plurality of stored one-dimensional correction tables. Shading is corrected (step S15) using the obtained one-dimensional correction table. Specifically, a random pixel is selected from main pixels, a correction value that corresponds to the position of the selected pixel is read from the obtained one-dimensional correction table for the main pixels, and shading is corrected according to the correction value and the pixel value of the random pixel. This process is implemented for all the main pixels and subpixels. A two-dimensional SD correction unit (67B) corrects the shading (step S16) for the shading-corrected (step S15) data in the regular manner by using a two-dimensional correction table.
