SPATIAL RADIOMETRIC CORRECTION OF AN OPTICAL SYSTEM HAVING A COLOR FILTER MOSAIC
In an optical system, a color filter mosaic can determine first color pixel locations, second color pixel locations, and third color pixel locations in an array of sensor pixels. The optical system can capture overhead images, which can be subtracted to form a background-subtracted tri-color image of a reflection of sunlight from at least one ground-based curved mirror. A processor can scale color values at the first and second color pixel locations of the tri-color background-subtracted image. The processor can form a single-color background-subtracted image from the scaled color values at the first color pixel locations, the scaled color values at the second color pixel locations, and third color values at the third color pixel locations. The single-color background-subtracted image can correspond to a point spread function or a line spread function of the optical system.

Pixel mixing device and method for controlling operation of same
It is determined whether an image before pixel mixture has a high frequency. In a partial image obtained by an imaging device having a Bayer array, a Gr pixel which indicates a green component and is arranged in the same row as an R pixel indicating a red component is distinguished from a Gb pixel which indicates a green component and is arranged in the same row as a B pixel indicating a blue component. The Gr pixels and the Gb pixels which are distinguished from each other are separately mixed. When an image before pixel mixture has a high-frequency component, the level of the Gr pixel and the level of the Gb pixel are different from each other after pixel mixture. It is determined whether the image before pixel mixture has a high-frequency component based on levels of the Gr pixel and Gb pixel after pixel mixture.
