What is YUV Colour model?

YUV is a color encoding system typically used as part of a color image pipeline. The Y′UV model defines a color space in terms of one luma component (Y′) and two chrominance components, called U (blue projection) and V (red projection) respectively.

What is YUV stand for?

composite analog signals
Through a process called “color space conversion,” the video camera converts the RGB data captured by its sensors into either composite analog signals (YUV) or component versions (analog YPbPr or digital YCbCr).

What is a YUV image?

android.graphics.YuvImage. YuvImage contains YUV data and provides a method that compresses a region of the YUV data to a Jpeg. The YUV data should be provided as a single byte array irrespective of the number of image planes in it. Currently only ImageFormat. NV21 and ImageFormat.

Why are YUV models preferred to RGB models?

YUV color-spaces are a more efficient coding and reduce the bandwidth more than RGB capture can. Most video cards, therefore, render directly using YUV or luminance/chrominance images. The most important component for YUV capture is always the luminance, or Y component.

When do you use the YUV color system?

Today, the term YUV is commonly used in the computer industry to describe file-formats that are encoded using YCbCr. The Y′UV model defines a color space in terms of one luma (Y′) and two chrominance (UV) components. The Y′UV color model is used in the PAL composite color video (excluding PAL-N) standard.

Why do we need the YUV file format?

YUV is like RGB which is used to represent a color. But why do we need it while we can represent color in RGB model? Becuase the file size matters. In RGB model we have to use 3 bytes (24 bits) to record a color, but in YUV model, we can half the size if we use yuv420p format.

How is the Y ′ UV color model used in PAL?

The Y′UV model defines a color space in terms of one luma (Y′) and two chrominance (UV) components. The Y′UV color model is used in the PAL composite color video (excluding PAL-N) standard. Previous black-and-white systems used only luma (Y′) information.

What does the Y and V In YUV mean?

“Y” means luminance (brightness), “U” and “V” means chrominance (color). YUV is like RGB which is used to represent a color. But why do we need it while we can represent color in RGB model? Becuase the file size matters.
