Abstract: An apparatus and method for geometrically correcting an arbitrary shaped input frame and generating an undistorted output frame. The method includes capturing arbitrary shaped input images with multiple optical devices and processing the images, identifying redundant blocks and valid blocks in each of the images, allocating an output frame with an output frame size and dividing the output frame into regions shaped as a rectangle, programming the apparatus and disabling processing for invalid blocks in each of the regions, fetching data corresponding to each of the valid blocks and storing in an internal memory, interpolating data for each of the regions with stitching and composing the valid blocks for the output frame and displaying the output frame on a display module.

Abstract: An image data frame is received from an external source. An error concealment operation is performed on the received image data frame in response to determining that a first frame size of the received image data frame is erroneous. The first frame size of the image data frame is determined to be erroneous based on at least one frame synchronization signal associated with the image data frame. An image processing operation is performed on the received image data frame on which the error concealment operation has been performed, thereby enabling an image processing module to perform the image processing operation without entering into a deadlock state and thereby prevent a host processor from having to execute hardware resets of deadlocked modules.

Abstract: A method for capturing video frames from a plurality of video channels is provided. A list of a least two descriptors is formed for each of the plurality of video channels in a memory accessible to a direct memory access (DMA) engine, wherein each of the two or more descriptors for each channel is programmed to define a storage location for a sequential frame of video data for the channel. A sequence of video frames is received from the plurality of video channels, wherein for each channel, video frames are received at a frame rate for that channel. A DMA engine uses descriptors from the list to store video frames as they are received. The list is updated periodically to replace used descriptors.
