Abstract: A signal processing IC unit performs image processing with respect to an output from a camera. A recognition processing IC unit performs recognition processing based on the output from the signal processing IC unit. A control IC unit outputs a control signal based on the output from the recognition processing IC unit. A first terminal is electrically connected to the recognition processing IC unit. A second terminal is electrically connected to the control IC unit. The signal processing IC unit, the recognition processing IC unit, and the control IC unit are disposed on a board. The first terminal and the second terminal are provided on an edge portion of the board.

Abstract: A camera system and method are disclosed. The camera includes a memory, a camera, and a processor. The memory stores an adaptively subsampled look-up table. The adaptively subsampled look-up includes varying levels of subsampling across the adaptively subsampled look-up table. The camera captures an image, and the captured image is distorted based on varying distortions within an optical system of the camera. The processor receives the captured image from the camera, corrects the distorted captured image based on the adaptively subsampled look-up table to create a correct image, provides the corrected image, and executes a safety feature based on the corrected image.

Abstract: Embodiments provide line-based feature generation for vision-based driver assistance systems and methods. For one embodiment, a feature generator includes a circular buffer and a processor coupled to an image sensor. The circular buffer receives image data from the image sensor and stores N lines at a time of an image frame captured by the image sensor. The N lines of the image frame are less than all of the lines for the image frame. The processor receives the N lines from the circular buffer and stores one or more features generated from the N lines in a memory. Iterative blocks of N lines of image data are processed to complete processing of the full image frame, and multiple frames can be processed. The generated features are analyzed by a vision processor to identify, classify, and track objects for vision-based driver assistance and related vision-based assistance actions.
