Abstract: Disclosed herein are techniques for camera illuminator control. These techniques can be used in cameras that include an RGBIR (red green blue infrared) camera sensor and two illuminators—one visible light illuminator and one infrared illuminator. The techniques provide timing and control for such cameras for a variety of different camera modes. Particular camera modes may be defined as having different camera mode values for different camera mode parameters. That is, any particular camera mode is defined by a particular camera mode value for each of a set of camera mode parameters. Different parameters include a flash periodicity parameter, a simultaneity parameter, an autoexposure mode parameter, a shutter mode parameter, and a frame drop parameter.

Abstract: A system and method for controlling characteristics of collected image data are disclosed. The system and method include performing pre-processing of an image using GPUs, configuring an optic based on the pre-processing, the configuring being designed to account for features of the pre-processed image, acquiring an image using the configured optic, processing the acquired image using GPUs, and determining if the processed acquired image accounts for feature of the pre-processed image, and the determination is affirmative, outputting the image, wherein if the determination is negative repeating the configuring of the optic and re-acquiring the image.

Abstract: A method and processing device for image demosaicing is provided. The processing device comprises memory and a processor. The processor is configured to, for a pixel of a Bayer image which filters an acquired image using three color components, determine directional color difference weightings in a horizontal direction and a vertical direction, determine a color difference between the first color component and the second color component and a color difference between the second color component and the third color component based on the directional color difference weightings, interpolate a color value of the pixel from the one color component and the color differences and provide a color image for display.
