IMAGING APPARATUS, AND LENS UNIT

PROBLEM TO BE SOLVED: To alleviate an error influence of a correction filter by adjusting an aberration correction amount in accordance with an image level.SOLUTION: When an input signal level is large, for example, when the photographing environment is bright or the like, an addition percentage of image data outputted from the filter for color aberration correction (a first filter 201AR and a third filter 201AB) is increased to obtain image data whose color aberration is corrected. When the input signal level is small, for example, when the photographing environment is dark or the like, an addition percentage of image data outputted from the filter for noise rejection (a second filter 201BR and a fourth filter 201BB) is increased to obtain the image data whose noise component included in the image is reduced.
