Abstract
A system may include one or more camera modules each containing one or more image sensors. The system may be configured to capture images from light spectra outside the visible band. Therefore, the pixel integration times, and frame rates of the one or more image sensors may be unique and distinct. An image sensor may respond to a trigger control signal by beginning integration of a subset of pixels some duration after an appropriate trigger control signal transitions from low to high. The image sensor may output the frame captured by the pixels a predetermined duration after the trigger control signal transitions, to ensure a deterministic response. Pixels used to generate the image of a subsequent frame may begin integrating during the readout of the current frame. The pixels may be integrated for exactly their programmed integration time, even when the frame rate is varied.
