We are having an issue with tuning an image and would like to get some clarification on a few things.
We are using a DM385 chip. The documentation states that LSC is used to set gains for the ISIF module and DC subtraction is needed before LSC. We are using the DCC tool to tune DC subtraction, LSC, and AWB (in that order). The main issue we are having is the offsets and gains in the ISIF module do not seem to be setting properly and the image is getting a slightly yellow tint. The following are a few specific questions but any insight into this would be appreciated.
Regarding IPNC 3.9.1: Is iss_03_80_00_00 the latest release of the ISS module software? The project we are working on has iss_03_80_00_70. Is there any documentation on changes made in this version?
What is the state of LSC and DC subtraction? Are they working as of this version? If so, what would be the best way to update them? They do not seem to be updating properly from the default DCC parameters.
Is it possible to get the source code containing the functions “dcc_update” referenced in idcc.h?
