Latency effect

Another effect is the latency and response time for events. As you get closer to the sensor, you enter the realm of hard real-time requirements. These systems are typically deeply embedded systems or microcontrollers that have latency set by real-world events. For example, a video camera is sensitive to the frame rate (typically 30 or 60 fps) and must perform a number of sequential tasks in a data flow pipeline (demosaicing, denoting, white balance and gamma adjusting, gamut mapping, scaling, and compression). The amount of data flowing through a video imaging pipeline (1080p video using 8-bits per channel at 60 fps)is roughly 1.5 GB/s. Every frame must flow through this pipeline in real time, therefore most video image signal ...
