An image capture device includes a plurality of independently formed camera channels. Each of the plurality of independently formed camera channels includes a respective lens that receives incident light and transmits the incident light to a respective sensor without transmitting the incident light to respective sensor of other camera channels within the plurality of independently formed camera channels. Further, a processor that is communicatively coupled to the respective sensor of each of the plurality of independently formed camera channels. The processor is configured to control an integration time of the respective sensor of each of the plurality of independently formed camera channels individually with the receive respective images from the respective sensor of each of the plurality of independently formed camera channels, and form a combined image by combing each of the respective images.

One example system comprises a LIDAR sensor that rotates about an axis to scan an environment of the LIDAR sensor. The system also comprises one or more cameras that detect external light originating from one or more external light sources. The one or more cameras together provide a plurality of rows of sensing elements. The rows of sensing elements are aligned with the axis of rotation of the LIDAR sensor. The system also comprises a controller that operates the one or more cameras to obtain a sequence of image pixel rows. A first image pixel row in the sequence is indicative of external light detected by a first row of sensing elements during a first exposure time period. A second image pixel row in the sequence is indicative of external light detected by a second row of sensing elements during a second exposure time period.

An electronic device is disclosed herein that includes an infrared light source to emit infrared light, a rolling shutter sensor, and at least one processor. The at least one processor is to: cause the rolling shutter sensor to output a first signal corresponding to a first frame of image data during exposure to the infrared light, reset the rows of the rolling shutter sensor at a same time, cause the rolling shutter sensor to output a second signal corresponding to a second frame of image data without exposure to the infrared light from the infrared light source, determine a difference between the first signal and the second signal to generate an ambient infrared free frame, and recognize a face based on the ambient infrared free frame.
