Image processing apparatus, image processing method, and camera module with shading correction

摘要

According to one embodiment, an image processing apparatus includes a shading correction unit. The shading correction unit executes at least one of the use of shading correction parameters calculated in accordance with exposure information for capturing a subject image and the adjustment of a center position in a two-dimensional direction which is used as the basis of the shading correction in accordance with the exposure information.

主权项

1. An image processing apparatus comprising:
a shading correction unit which calculates a correction amount for shading correction on a subject image; an auto white balance/auto exposure arithmetic unit which calculates a coefficient for auto white balance adjustment and a coefficient for auto exposure adjustment; and a digital amplifier coefficient circuit which calculates a digital amplifier coefficient on the basis of the coefficients calculated by the auto white balance/auto exposure arithmetic unit and the correction amount calculated by the shading correction unit, and multiplies the digital amplifier coefficient by an image signal obtained by capturing the subject image, wherein the shading correction unit executes at least one of use of shading correction parameters calculated in accordance with exposure information which is the coefficient for auto exposure adjustment in the calculation of the correction amount, and adjustment of a center position in a two-dimensional direction which is used as the basis of the shading correction in accordance with the exposure information.
