Abstract:
This invention provides an image processing device that can perform shading correction while accurately identifying a light source. An imaging device (1) is provided with the following: a trial shading-correction unit (315) that performs trial shading correction on image data for each of a plurality of types of light source on the basis of correction information stored in a correction-information storage unit (311) for each light-source type; a correction-information selection unit (316) whereby the results of the shading correction performed by the trial shading-correction unit (315) for each light-source type are compared to each other and correction information corresponding to an appropriate shading-correction result is selected from among the correction information stored by the correction-information storage unit (311) per light-source type; and a shading correction unit (317) that performs color-shading correction on the image data on the basis of the correction information selected by the correction-information selection unit (316).
