The purpose of this project is to get HDR images using an Elphel camera. The project development is supported by Waveng.com.
For informations about HDR imaging see: Wikipedia.org
In order to get a HDR image, the camera executes the following steps:
1. acquisition of n LDR (Low Dynamic Range) images with different exposure time;
2. computation of the n acquired images;
3. generation of the HDR image.
The features of the camera needed to execute this cycle are:
1. exposure time must vary during the acquisition process;
2. a memory to temporary save the acquired images;
3. a quite powerful CPU for image computation.
The Elphel camera satisfies all these requirements.
