Abstract
In a digital image processing device such as a portable digital camera, an analog decimation circuit is provided as a front end for the digital video imaging circuit so that the data rate is reduced without substantial loss in fidelity so that the power dissipation is minimized. In a decimation circuit, the data rate is reduced by reducing only higher frequency spectral components of a captured image without substantial loss in fidelity of the remaining spectral components of the captured image. The required amount of digital data processing is so substantially reduced that considerable power savings result. A mixture of decimation modes may be effected using the same circuit.
