RGB_TO_YCBCR

RGB to YUV Conversion Y = (0.257 * R) + (0.504 * G) + (0.098 * B) + 16 Cr = V = (0.439 * R) - (0.368 * G) - (0.071 * B) + 128 Cb = U = -(0.148 * R) - (0.291 * G) + (0.439 * B) + 128 YUV to RGB Conversion B = 1.164(Y - 16) + 2.018(U - 128) G = 1.164(Y - 16) - 0.813(V - 128) - 0.391(U - 128) R = 1.164(Y - 16) + 1.596(V - 128) In both these cases, you have to clamp the output values Y��CbCr is often confused with the YUV color space, and typically the terms YCbCr and YUV are used interchangeably, leading to some confusion; when referring to signals in video or digital form, the term "YUV" mostly means "Y��CbCr". Y'UV is often used as the term for YCbCr. However, they are different formats. Y'UV is an analog system with scale factors different from the digital Y'CbCr system.[5] In digital video/image systems, Y'CbCr is the most common way to express color in a way suitable for compression/transmission. The confusion stems from computer implementations and text-books erroneously using the term YUV where Y'CbCr would be correct. Y << 10 = (263 * R) + (516 * G) + (100 * B) + 16384 Cr << 10 = (450 * R) - (377 * G) - ( 73 * B) + 131072 Cb << 10 = -(152 * R) - (298 * G) + (450 * B) + 131072 Y << 10 = (20'h00107 * R) + (20'h00204 * G) + (20'h00064 * B) + 20'h04000 Cr << 10 = (20'h001C2 * R) + (20'hFFE87 * G) + (20'hFFFB7 * B) + 20'h20000 Cb << 10 = (20'hFFF68 * R) + (20'hFFED6 * G) + (20'h001C2 * B) + 20'h20000
