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.

150px nonHDR image with global analog gain=1
150px nonHDR image with global analog gain=16
150px HDR source image with gained G2
150px processed HDR image

Matlab have interesting 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.
