  • Patent number: 10044952
    Abstract: The present disclosure provides an adaptive shading correction method for correcting an image for lens shading, including segmenting the image into a plurality of blocks of pixels and identifying hue-flat blocks with a relatively low hue variance, where the hue-flat blocks are clustered into at least one cluster based on a spatial distribution of the blocks. Selected modification parameters for modifying an average shading mesh are identified by modifying the average shading mesh along a plurality of dimensions using a plurality of modification parameters, and processing the at least one cluster with the average shading mesh as modified so as to identify the selected modification parameters. The average shading mesh is modified using the selected modification parameters to generate a shading correction mesh, which is used to correct the image for lens shading.

  • Patent number: 9961269
    Abstract: An imaging device includes an APD filter. A first program diagram is selected in a case in which the APD filter is not disposed, and a second program diagram is selected in a case in which the APD filter is disposed. A set of an imaging diaphragm value AV and an imaging shutter speed TV is determined on the basis of an exposure value obtained from a photometric value obtained from a photometric unit. The first program diagram is a multiple-stage diaphragm type program diagram. In the first program diagram, diaphragm values AV take discrete values at an interval of a first value. In the second program diagram, a part of corrected diaphragm values, which are obtained by correcting diaphragm values of the first program diagram on the basis of optical characteristics of the APD filter, are thinned out so that each interval has at least a second value.
