The analogue +crop is configured using the ``V4L2_SEL_TGT_CROP`` on the source pad (0) of the +entity. The size of the pixel matrix can be obtained by getting the +``V4L2_SEL_TGT_NATIVE_SIZE`` target. + +Binner +------ + +The binner sub-device represents the binning functionality on the sensor. For +that purpose, selection target ``V4L2_SEL_TGT_COMPOSE`` is supported on the +sink pad (0). + +Additionally, if a device has no scaler or digital crop functionality, the +source pad (1) expses another digital crop selection rectangle that can only +crop at the end of the lines and frames. + +Scaler +------ + +The scaler sub-device represents the digital crop and scaling functionality of +the sensor. The V4L2 selection target ``V4L2_SEL_TGT_CROP`` is used to +configure the digital crop on the sink pad (0) when digital crop is supported. +Scaling is configured using selection target ``V4L2_SEL_TGT_COMPOSE`` on the +sink pad (0) as well. + +Additionally, if the scaler sub-device exists, its source pad (1) exposes +another digital crop selection rectangle that can only crop at the end of the +lines and frames. + +Digital and analogue crop +------------------------- + +Digital crop functionality is referred to as cropping that effectively works by +dropping some data on the floor. Analogue crop, on the other hand, means that +the cropped information is never retrieved. In case of camera sensors, the +analogue data is never read from the pixel matrix that are outside the +configured selection rectangle that designates crop.
