    • An image capturing apparatus having an image capturing portion that captures an image of an object, a memory that has an area for storing reference gain information representative of a reference gain value for each of R, G and B at a predetermined pixel point in each block when an assumed image area corresponding to the captured image is divided into a plurality of blocks, an interpolator that calculates the gain value for each color for each pixel in each block by an interpolation calculation based on the reference gain information stored in the memory, and a shading corrector that receives interpolation gain information representative of the gain value calculated by the interpolator and the reference gain information, and performs color shading correction on the captured image based on the received interpolation gain information and reference gain information.
    • 一种具有拍摄对象图像的图像捕获部分的图像捕获装置,具有用于存储表示每个块中的预定像素点的R,G和B中的每一个的参考增益值的参考增益信息的区域的存储器 当对应于拍摄图像的假想图像区域被划分成多个块时,内插器通过基于存储在存储器中的参考增益信息进行内插计算来计算每个块中每个像素的每种颜色的增益值,以及 阴影校正器,其接收表示由内插器计算的增益值的内插增益信息和参考增益信息,并且基于接收到的内插增益信息和参考增益信息,对拍摄图像执行着色校正。
