Abstract: A method for displaying a surround view on a single display screen is disclosed. A plurality of image frames for a particular time may be received from a corresponding plurality of cameras. A viewpoint warp map corresponding to a predetermined first virtual viewpoint may be selected, wherein the viewpoint warp map defines a source pixel location in the plurality of image frames for each output pixel location in the display screen. The warp map was predetermined offline and stored for later use. An output image is synthesized for the display screen by selecting pixel data for each pixel of the output image from the plurality of image frames in accordance with the viewpoint warp map. The synthesized image is then displayed on a display screen.

Abstract: A system on a chip (SoC) implementing dynamic grouping of multiple cameras in an image processing system is disclosed. The SoC includes an image signal processor (ISP) configured to receive a signal corresponding to an image from two or more cameras, dynamically group the cameras into groups based on a measured view brightness and/or color temperature observed by each of the cameras, and assign cameras with a group of the groups to a same exposure/gain setting. The SoC further includes a statistics engine configured to receive the image signals and statistics related to the image signals from the ISP and determine a measurement of image brightness and/or color temperature of each image based on the image signals for forwarding to the ISP.
