• abstract: Visual tasks for embedded systems are confronted with strong constraints on power consumption. Algorithms have to be both robust and compliant to various environments while being computationally and power efficient. An architecture of CMOS image sensor tailored to implement a class of robust motion detection algorithms based on recursive operations, allowing sensor's acuity adaptation to the scene activity, is exposed. The main interest is that in a context of embedded steady camera, such a system allows to focus on targets with high resolution while keeping background in low resolution. Drastic power consumption reduction is achieved by tremendously reducing the amount of processed data.
