1. A cell phone including a microphone and a cellular radio transceiver, and additionally comprising: an image sensor; a human visual system processing module, selected from the group consisting of a white balance correction module, a gamma correction module, an edge enhancement module, and a JPEG compression module; a machine vision processing module, selected from the group consisting of an FFT module, an edge detection module, a pattern extraction module, a Fourier-Mellin transformer, a texture classifier, a color histogram module, a SIFT processor, and a SURF processor; and an interconnection arrangement; wherein the machine vision processing module employs processing circuitry integrated on a common substrate with the image sensor, and wherein the interconnection arrangement couples image data from the image sensor to the machine vision processing module without passing through the human visual system processing module.
