An electronic system including signal processing circuitry that can operate in video and still image modes. Incoming image data is processed and compressed according to the operating mode. Processing includes scaling logic configured to use scaling methodologies appropriate to each mode. Compressing includes using compression methodologies appropriate to each mode.

Dual mode signal processing system for video and still image data

A method for downscaling an image from a sensor color filter array space having the step of determining an initial image size. The method also has steps of determining a set of stride lengths, locating a single color pixel of interest, and generating a full color pixel. An apparatus having a processor and a memory coupled to the processor for performing the above steps is also disclosed.

Method and apparatus for rapid down-scaling of color images directly from sensor color filter array space

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.
