HDR JP4
Bayer pattern look like this
| R | G1 | R | G1 | R | G1 |
| G2 | B | G2 | B | G2 | B |
| R | G1 | R | G1 | R | G1 |
| G2 | B | G2 | B | G2 | B |
| R | G1 | R | G1 | R | G1 |
| G2 | B | G2 | B | G2 | B |
Some sensors have possibility to set independed scale to G1 and G2. Considering that the accessible optics does not give the full permission of a sensor resolution, it can be used for increase in a dynamic range of a image sensor.
Interested Matlab possibility for creating HDR from series of LDR images.
We can easy make script for online & one click make HDR from series of images with different exposure times.
