Abstract: A video display pipe used for processing pixels of video and/or image frames may include edge Alpha registers for storing edge Alpha values corresponding to the edges of an image to be translated across a display screen. The edge Alpha values may be specified based on the fractional pixel value by which the image is to be moved in the current frame. The video pipe may copy the column and row of pixels that are in the direction of travel, and may apply the edge Alpha values to the copied column and row. The edge Alpha values may control blending of the additional column and row of the translated image with the adjacent pixels in the original frame, providing the effect of the partial pixel movement, simulating a sub pixel rate of movement.

Abstract: método e sistema de processamento de imagem de sensor de imagem duplo. trata-se de várias técnicas fornecidas para processar dados de imagem adquiiridos com o uso de ums ensor de imagem digital 90. de acordo com aspctos da presente revelação, tal técnica pode se referir ao processamento de dados de imagem em um sistema 10 que suporta múltiplos sensores de imagem 90. em uma modalidade, o sistema de processamento de imagem 32 pode incluir circuitos de controle configurados para determinar se um dispositivo está operando em um modo de sensor único (um sensor ativo) ou um modo de sensor duplo (dois sensores ativos). durante a operação no modo de sensor único, os dados podem ser fornecidos diretamente para uma unidade de processamento de pixel front-end 80 da interface de sensor do sensor ativo. durante a operação em um modo de sensor duplo, os quadros de imagem do primeiro e do segundo sensores 90a, 90b são fornecidos para a unidade de processamento de pixel front-end 80 de uma forma intercalada. por exemplo, em uma modalidade, os quadros de imagem do primeiro e do segundo sensores 90, 90b são descritos para uma memória 108, e então lidos para a unidade de processamento de pixel front-end 80 de uma forma intercalada.

Abstract: Various techniques are provided for processing image data acquired using a digital image sensor 90. In accordance with aspects of the present disclosure, one such technique may relate to the processing of image data in a system 10 that supports multiple image sensors 90. In one embodiment, the image processing system 32 may include control circuitry configured to determine whether a device is operating in a single sensor mode (one active sensor) or a dual sensor mode (two active sensors). When operating in the single sensor mode, data may be provided directly to a front-end pixel processing unit 80 from the sensor interface of the active sensor. When operating in a dual sensor mode, the image frames from the first and second sensors 90a, 90b are provided to the front-end pixel processing unit 80 in an interleaved manner. For instance, in one embodiment, the image frames from the first and second sensors 90a, 90b are written to a memory 108, and then read out to the front-end pixel processing unit 80 in an interleaved manner.

Abstract: A user interface unit in a graphics processing display pipe may include registers programmable with information that defines active regions of an image frame. Pixels within the active regions of the image frame are meant to be displayed, while pixels outside of the active regions of the image frame are not to be displayed. Fetch circuitry within the user interface unit may fetch frames from memory, fetching only the pixels within the active regions of the image frames as defined by the programmed contents of the registers. The user interface unit may then provide the fetched pixels to a blend unit to blend the fetched pixels with pixels from other frames or pixels of a video stream to produce output frames. When blended with pixels of a video stream, the fetched pixels may be displayed as a graphics overlay on top of the video stream.
