Three Images Blending Engine Supporting Multicolor Formats,Various Color Depths with Small-Gate Size and High-Quality Image for SOC Design
A small Color Space Conversion (CSC) block in Video Input/Output (VIO) architecture can efficiently support both standards: ITU-R BT.601 and ITU-R BT.709 for rGB and YCbCr color format. The design of an arbitrary (programmable) coefficient helps to reduce the size of CSC block. A new dithering technique is implemented to achieve the advantages,high-qualily image and no buffer memory,of Error-diffusion algorithm and Ordered algorithm.With a small gate count,VIO can also support effectively 4 different inputs with multicolor format,various color depth. This VIO has been used in a SOC chip for mobile phone. The detail of VIO design is described in this paper.
