The camera subsystem provides the system interfaces and the processing capability to connect raw, YUV or JPEG image sensor modules to the device for video-preview, video-record and still-image-capture applications. The camera ISP2P subsystem supports up to two simultaneous pixel flows but only one of them can use the video processing hardware: · Parallel camera interface + Serial camera interface: one interface data goes through the video processing hardware. The other interface data goes directly to memory · Serial camera interface + Serial camera interface: one serial interface data goes through the video processing hardware. The other serial interface data goes directly to memory. Note: For more information, see the Camera ISP / Camera ISP Environment / Camera ISP Connectivity Schemes section of the AM/DM37x Multimedia Device Technical Reference Manual (literature number SPRUGN4).
