Detecting IR light using DM365

Sudheesh
Expert 1945 points

 If the CMOS image sensor that is connected to DM365 is near IR range capable, how can we detect the presence of IR light from the Image sensor interfaces available in DM365? I could not find any relevant information in the available VPFE document. Please help me regarding this.

 

 

Thanks

    tvs,

    Near IR will be sensed by the red pixels with no IR filter. You can just look at the relative red pixel signal.  Note for normal non IR applications an IR cut filter is used to cut off the signal.

    If you talk about near IR sensor (instead of Bayer RGB sensor), then the answer is still yes but ISP parameter setup needs to be somewhat different from typical Bayer RGB processing. The main reason is IR sensor has the same format in each pixel where Bayer RGB sensor has different color format in neighbor pixels.
