1. An image processing system comprising:

  • signal processing circuitry that is configurable to operate in one of at least two modes to yield video and still image data, the processing circuitry including scaling logic for spatially scaling image data related to sensor signals into scaled image data, and compression logic for compressing the scaled image data into compressed image data, wherein in the first mode, the scaling logic is configured to scale according to a first scaling methodology suitable for generating video image data, and the compression logic is configured to compress according to a first compression methodology suitable for generating video image data, and wherein in the second mode, the scaling logic is configured to scale according to a second scaling methodology suitable for generating still image data, and the compression logic is configured to compress the scaled image data according to a second compression methodology suitable for generating still image data.
