Description: Convert a color image between color representations.
B = COLORSPACE(S,A) converts the color representation of image A
where S is a string specifying the conversion. S tells the
source and destination color spaces, S = dest<-src , or
alternatively, S = src->dest . Supported color spaces are
RGB R G B Red Green Blue (ITU-R BT.709 gamma-corrected)
YPbPr Luma (ITU-R BT.601) + Chroma
YCbCr / YCC Luma + Chroma ("digitized" version of Y PbPr)
YUV NTSC PAL Y UV Luma + Chroma
YIQ NTSC Y IQ Luma + Chroma

Description: Camera Interface模块是视频输入转换存储模块。该模块一端接通用的video camera设备，另一端接AHB总线。实现了将Camera捕捉到的数据进行转换、并通过DMA存储到memory中。该IP支持ITU-R BT 601/656 8-bit 模式。支持YCbCr, RGB格式输入。可以将camera产生的YCbCr信号转换成24bit RGB 信号，然后下采样生成16bit RGB 5：6：5的LCD能直接读取显示的数据。该设备支持图像的镜像和翻转，以便适应手持式设备在移动环境中图像的捕捉。可变的同步信号极性使得可以兼容各种摄像头外设。Camera Interface兼容AMBA规范， AHB SLAVE接口，用于读取软件配置数据和设置数据存放地址和1帧数据占用的空间。-The Camera IP Core is small and flexible video data coverter. It is connected to a typical video camera ICs with 8-bit digital video data, Horizontal synchronization and Vertical synchronization signals. The core is connected through FIFO to a WISHBONE bus on the other side. Both sides of the core can operate at fully asynchronous clock frequencies. The Camera IP Core convertes 4:2:2 YCbCr video data (sometimes called YUV, but not totally the same Y is the same, while Cb and Cr are U and V multiplied by a constant) to a 24-bit RGB. 24-bit or 16-bit RGB data, downsampled from 24-bit RGB, is then sent to the system (video) memory, however conversion can also be by-passed. Interrupt can be generated after frame-buffer in system (video) memory is filled up or after setable number of horizontal lines written to frame-buffer.

Description: Takes as an input an RGB image (or the name/path of an RGB image) and creates a figure in which you can see side-by-side the original, the grayscale (RGB2GRAY), and the individual R,G, and B color planes.
Advanced mode also displays some colorspace conversions (HSV, YCbCr, L*a*b*) of the image.
Click on any image to expand it (requires expandAxes) and then right-click to export image to base workspace.
This is a very simple but useful utility for deciding, for instance, how you want to process/segment a color image.

Description: 颜色空间转换：RGB空间-->ycbcr空间。速度比ColorSpace调用快多了。
调用格式[y, cb, cr] = rgb2ycbcr(img)
输入img: rgb彩色图；y: 亮度，cb：蓝色，cr：红色
调用参考runTest.m-Color space conversion, RGB to ycbcr
call format: [y, cb, cr] = rgb2ycbcr(img)
input img: rgb image
output r: intensity, cb: blue, cr: red
Example see runTest.m
