Abstract: An apparatus comprising a memory and one or more processing circuits is provided. The memory stores a blend table having blend weights. The processing circuits, for partitions of the blend table: determine whether a subset of the pixels associated with the partition includes pixels associated with seamlines defined in a three-dimensional surface representation of the scene. If none of the subset of the pixels are associated with the seamlines, the processing circuits populate a region of the virtual image corresponding to the partition with pixel values from an image captured by one of the plurality of image capture devices. If one or more of the subsets of the pixels is associated with the seamlines, the processing circuits populate the region of the virtual image associated with the partition with blended pixel values from two or more images captured by two or more of the plurality of image capture devices.

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: Described examples include a system including a projector configured to project a test pattern image, the test pattern image having at least two elements; a camera configured to capture the test pattern image; and a controller coupled to the projector and to the camera. The controller is configured to obtain a first calibration matrix between the projector and the camera for the at least two elements; determine at least two epipolar lines based on the first calibration matrix and the test pattern image; determine a cost function based on the at least two epipolar lines and the at least two elements in the test pattern image as captured by the camera; and determine a second calibration matrix responsive to the cost function, wherein at least one of a camera position of the camera or a projector position of the projector is adjusted responsive to the second calibration matrix.

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.
