Multi-Line Technology: Long and Short Exposure HDR
What is HDR: High Dynamic Range The main function of HDR is to make a picture
* Dark areas (underexposed), become brighter
* bright areas (overexposure), become darker
To describe HDR in layman's terms, that is: the light and dark of different areas of the photographed object, there is a stronger adaptability, so that all areas can be clearly imaged
There are many ways to implement HDR, and for line cameras, there is an implementation technique called long and short exposure
* odd rows: short exposure
* Even rows: long exposure
* The final 2 images are obtained, and using an algorithm, the 2 images are combined into one to get an HDR image
Note: is an odd number of lines of short exposure or even lines of short exposure, this does not matter.
The focus is on the interlinear length, short exposure on it
