Abstract: A method for automatic exposure (AE) control is provided that includes receiving statistics for AE control for an image from an image signal processor (ISP) coupled to an image sensor generating the image, computing an exposure value at a current time t (EV(t)) using a cost function based on target characteristics of an image, wherein computation of the cost function uses the statistics, and computing AE settings for the image sensor based on EV(t).

Abstract: Digital mirror systems for vehicles and methods of operating the same are disclosed. An example vehicle control system includes: a driver monitoring system including a head position determiner to determine at least one of a location of a head, an orientation of the head, or an eye gaze point of the head; a digital mirror system including a region-of-interest (ROI) detector to identify an ROI based on the at least one of the location of the head, the orientation of the head, or the eye gaze point of the head, and a cropper to extract a portion of a first image corresponding to the ROI to form a second image, the first image representing an area exterior to the vehicle; and a display within an interior area of the vehicle to present the second image.

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.
