    摘要: An image capture system comprises an image input and processing unit. The image input obtains image information which is then passed to the processing unit. The processing unit is coupled to the image input for determining image metrics on the image information. The processing unit initiates a capture sequence when the image metrics meet a predetermined condition. The capture sequence may store one or more images, or it may indicate that one or more images have been detected. In one embodiment, the image input is a CMOS or CCD sensor.

    摘要: An application processor and coprocessor communicate data, including command and control data, over a separate high-speed datapath. The data may be formatted into a pixel-stream format suitable for sending over the datapath. The application processor may utilize a graphics interface to send pixel-stream formatted data to a graphics interface of the coprocessor over the high-speed datapath rather than over a system bus. The coprocessor may reformat the formatted data to control and drive a graphics display.

    摘要: A projection system includes a display panel, a light modulator and at least one light sensor. The display panel has an exterior surface that is adapted to receive a first light wave that is indicative of at least one command. An interior surface of the display panel is adapted to receive a second light wave to form an image on the display panel. The light modulator is adapted to produce the second light wave, and the light sensor(s) are adapted to furnish an electrical indication of the command(s) in response to the first light wave.

    摘要: A cost effective digital image capture apparatus such as a digital camera that operates in both still mode and video mode, using a common programmable image processing chain and fixed optics. The full resolution of the image sensor (yielding raw image data) may be used in still mode, with adequate signal-to-noise ratio (SNR) achieved either from the scene ambient lighting or from supplemental light supplied by a strobe. In video mode, the apparatus may be configured to capture video image data by programming the parameters for image processing methodologies such as scaling, decorrelation, and encoding into a look-up table (LUT) which in turn configures logic circuitry to spatially scale and compress if necessary the raw image data in order to meet storage and transmission bandwidth constraints for video images. In video mode, adequate SNR may be achieved despite the lower light conditions, encountered, for example, during videoconferencing, by averaging pixels together during scaling.
