Sensor device and method for operating a sensor device

A method for operating a sensor device that is configured to capture a video of a scene, the method comprising:

• receiving light and performing photoelectric conversion with each of a plurality of pixels to generate a pixel signal with each of the pixels, the plurality of pixels comprising a first subset of pixels and a second subset of pixels, where pixels of the first subset of pixels are capable to generate pixel signals faster and preferably with less spatial resolution than pixels of the second subset of pixels, and wherein color frames can be generated from the pixel signals of the second subset of pixels;
• receiving and processing the pixel signals by a processing unit in order to generate video data;
• and
• receiving pixel signals from the first subset of pixels in a control unit and controlling, by the control unit, operation modes of the processing unit based on the received pixel signals from the first subset of pixels.
