Abstract

Nowadays, image sensors are widely used for industrial or augmented and virtual reality (AR)/(VR) applications. Often, multiple sensors are used and the host platform needs to process each high resolution image frame with low latency. Therefore, the processing units and the communication have a big impact on the power consumption of the image processing system. This paper describes a method to simulate a smart image sensor and the impact of different output resolutions on the image processing system. In-sensor processing is simulated, by sending different image resolutions to the host platform, where a shape matching algorithm was processed. It shows an analysis of the power consumption of the communication from the sensor with region-of-interest (ROI) data to the host and the energy consumption of the whole image processing system with a Mira220 and an Nvidia Jetson Nano. The power consumption of the MIPI interface can be reduced by over 83% for ROIs smaller than 640×480. Furthermore, the system energy consumption can be reduces by 18% at 90 fps and 21% at 60 fps.
