Area vs Binned Read¶

ReadCCDArea() command reads a rectangular region (Region of Interest) of the sensor and returns 16 bit unsigned integers. The values read back are the raw pixel values. The Region of Interest (ROI) can be altered by the CLSetCCDArea() command.

The Camera supports both vertical and horizontal binning. To perform a binned read operation, first setup binning configuration using CLSetBinParam() followed by calling CLReadCCDBinned() to read back the data. Pixel data read back using binned read is returned as 32 bit signed numbers. If the binning is done on the sensor then the values are less than 65535 - the limit of the ADC. However, pixel values may be larger than 65535 for configurations that use the DSP to digitally bin following CCD readout.
