What is the real size of the shading image
(MaxImageSize)?
The register 0xF1000258 SHDG_INFO (MaxImageSize) delivers the sensor size
but not the size of the shading image buffer.
Therefore: If you use this reported (but wrong) MaxImageSize then:
• A shading image which is too small will be uploaded/downloaded.
• The shading correction will only be applied on the first field.
• In Format_7 there will be a row-wise image error
To avoid using a wrong MaxImageSize read the following notes:
The camera’s internal buffer for the shading image is greater than the sensor
image. Therefore the buffer is divided in N sections with:
After each field there is a gap so you can see where each field ends and where
the next field begins:
Field 1 MaxImageSize/Fields
