Abstract: The present invention relates to a method for generating real-time motion video. The method comprises receiving, at a video processing device, calibration data from a memory in an image sensor unit, the calibration data relating to properties of the image sensor unit. The video processing device receiving real-time raw image data from the image sensor unit via a communication cable and a communication protocol. The video processing device processing the real-time raw image data received from the image sensor unit, where the processing includes adjusting received image data based on at least part of the received calibration data and encoding the image data to a predetermined video format, and outputting the processed image data in real time.

Abstract: A monitoring camera is connected to an external power source. The external power source has an external maximum power level. Image data is being processed in a first processing state. The monitoring camera detects (202) an event and determines (206) a type of the detected event. An amount of energy in an energy accumulator is determined (208) in the monitoring camera. Based on the type of the event and based on the external maximum power level and based on the determined amount of energy in the energy accumulator, a second processing state is determined (210). The second processing state requires a power level that is higher than the external maximum power level. Image data is then processed (212) in the second processing state.

Abstract: An image acquisition device and a method for capturing image data is disclosed. The method comprises exposing an image sensor to light from a scene, selecting substantially all rows of sensor pixels in an image sensor in a substantially random order, starting an exposure period for each row of sensor pixels in the image sensor in the order the rows were selected, buffering the rows of sensor pixels comprised in an image frame until all rows of the image frame have registered image data for the presently captured image frame, and outputting image data representing the image frame by outputting image data from each row of sensor pixels.
