A biochemistry measurement method includes obtaining a first pixel array and a second pixel array with a photosensitive array, transforming the first pixel array and the second pixel array into a first color space coordinate matrix and a second color space coordinate matrix, extracting the first color space coordinate matrix and the second color space coordinate matrix to from a third color space coordinate matrix and a fourth color space coordinate matrix, and obtaining a color space vector matrix according to the third color space coordinate matrix and the fourth color space coordinate matrix.
