摘要：
An image sensing apparatus, a color-correction matrix correcting method and a look-up table establishing method are provided. The image sensing apparatus calculates a block statistics value corresponding to a block of pixels in an image sensor array. Based on a look-up table, the image sensing apparatus determines a covariance value corresponding to a current gain value. According to the covariance value and the block statistics value, the image sensing apparatus corrects a color-correction matrix corresponding to the block of pixels. The image sensing apparatus can use an amended color-correction matrix to correct the color of the pixel, so as to reduce chroma noise or other noise.
