and chromatic aberration by three signals, and sends out the same channel. This method of color representation is called YUV color space representation.
This shows that RGB and YUV belong to the color space (or "color space"), if not clear the concept of color space.
Two, the advantages and disadvantages of RGB and YUV
1.RGB lack of good compatibility with early Black-and-white display systems. Therefore, many electronic appliances manufacturers commonly adopted the practice is to convert RG
recording will undoubtedly have a higher image quality. In practice, however, this is often not the case, because it greatly widens the bandwidth of the video signal, increases the cost of the associated equipment, and the second is incompatible with the current black and white. The three primary colors are combined into luminance (Y) and chroma (U,V) signals in a certain proportion, and the relationship between them is as follows: In order to enable

the recognition of color, the light is decomposed into a solid color mode of three primary colors by means of a light filter and a spectrophotometer. Then the solid color brightness of the three primary colors is collected, and then the signal is superimposed to realize the acquisition ability of the color signal.How is the color signal expressed?Because the original black and white, basically only need a signal to restore the image (synchronous signal behind). But with color, can the signal ex
half that of the luminance channel, so the chroma sampling rate in the horizontal direction is only half of the 4:4:4. For uncompressed images of 8-bit quantization, the macro pixel of each pixel that consists of two horizontal orientations is required to occupy 4 bytes of memory (2 bytes in brightness, two pixels per 1 bytes). .
The following four pixels are: [Y0 U0 V0] [Y1 U1 V1] [Y2 U2 V2] [Y3 U3 V3]
The stored stream is: Y0 U0 Y1 V1 Y2 U2, Y3 V3

In the world of FPS, 0.01 seconds determines life and death.However, too long keylinks often make you "lost ".

s terminal is also a very common terminal, its full name is separate video, also known as SUPER video. S-video Connection specification is a specification developed by the Japanese, s refers to the "separate (separation)", which separates the brightness and chroma from the output, avoiding the interference of brightness and chroma when the mixed video signal is output. The S-terminal is actually a five-core
In the H264 standard, the core of the coding layer is the macro block, a macro block size of 16x16, a 16x16 brightness block, and two 8x8 chroma blocks for commonly used 4:2:0 sampling formats. corresponding to the similar structure in HEVC is the coding tree Unit (CTU), its size can be specified by the encoder, the maximum can be supported to 64x64, the minimum can be supported to 16x16. For high-resolution video encoding, using a larger size of CTU

, filters are often used to filter the pixels at the block boundary to smooth out the mutation of the pixel value, which is called a de-block filter (deblocking filter).The content of the block filter is specified in the Standard 8.7 section, which is called the Loop filter. Loop filter is placed in the decoded image reconstruction loop. In a codec environment where loop filtering is enabled, both the encoder and the decoder are filtered after the image has been reconstructed. In the encoder, th

"High speed noise" refers to the high ISO sensitivity when shooting a variety of noise, it can be measured by the number of high ISO sensitivity of the practicality. How can EOS 7D control these noises and use the "high ISO speed noise reduction function" (NR) to what extent does it reduce noise? The following will be validated under ISO sensitivity.

A. JPEG compression process
JPEG compression is implemented in four steps:
1. Color mode conversion and sampling;
2.DCT transform;
3. Quantification;
4. Code.
Two.
1. Color mode conversion and sampling RGB color system is our most common way of representing color. JPEG uses the YCbCr color system. To use the JPEG basic compression method to process Full-color images, you must first convert the RGB color pattern image data to YCbCr color mode data. Y represents brightness, CB and CR represent
