More than one region of interest can be used with pl_exp_setup_seq or pl_exp_setup_cont functions. The number of ROIs supported by the camera can be obtained by reading PARAM_ROI_COUNT with ATTR_MAX prior to configuring the acquisition. The Embedded Frame Metadata feature must be enabled in order to use multiple ROIs.
To acquire a multi-ROI frame, a sequence of steps should be followed:
rgn_array
and rgn_total
specifying the array of regions to capture.
