从平面到像素阶数据的转换: HmppResult HMPPI_YCbCrToRGB_8u_P3C4R(const uint8_t* src[3], int32_t srcStep, uint8_t *dst, int32_t dstStep, HmppiSize roiSize, uint8_t aval); 参数
B = Y + (443(Cb - 128))>>8 To use look-up table, we can change to following format: RGB => YCbCr: We adjust a little of the factors to avoid saturation operation to improve performance Y = (77R + 150G + 29B)>>8 Cb = (128B – 43R – 85G)>>8 + 128 = (32768 + 12...
<!DOCTYPE html> RGBToYCbCr422 将RGB图像转换为YCbCr图像,采样为4:2:2。 此函数将伽马校正的R'G'B'图像src转换为Y'Cb'Cr'图像dst,采样格式为4:2:2。其中转换公式与函数RGBToYCbCr相同。 像素阶图像的转换缓冲区的位深度降低为每像素16位,而源缓冲区的位深度为24位。 函
When the Y range of [0,255],UV range of [0,255],the YCbCr to RGB formula is : R = Y + + (Cr - 128) * 1.40200 G = Y + (Cb - 128) * -0.34414 + (Cr - 128) * -0.71414 B = Y + (Cb - 128) * 1.77200 When the Y range of [16,235],UV range of [16,240],the ...
YCbCr to RGB Considerations Introduction Many video ICs now generate 4:2:2 YCbCr video data. The YCbCr color space was developed as part of ITU-R BT.601 (formerly CCIR 601) during the development of a world-wide digital component video standard. ...

A method is provided for upsampling a received YCbCr signal. The method generates the missing chrominance coefficients for each individual pixel, with a view to converting the data in the RGB color space. The method takes into account the values of the chrominance coefficients actually received for...
