A digital imaging system is described that provides techniques for
reducing the amount of processing power required by a given digital
camera device and for reducing the bandwidth required for transmitting
image information to a target platform. The system defers and/or
distributes the processing between the digital imager (i.e., digital
camera itself) and the target platform that the digital imager will
ultimately be connected to. In this manner, the system is able to
decrease the actual computation that occurs at the digital imager.
Instead, the system only performs a partial computation at the digital
imager device and completes the computation somewhere else, such as at a
target computing device (e.g., desktop computer) where time and size are
not an issue (relative to the imager). By deferring resource-intensive
computations, the present invention substantially reduces the processor
requirements and concomitant battery requirements for digital cameras.
Further, by adopting an image strategy optimized for compression
(compressed luminosity record), the present invention decreases the
bandwidth requirements for transmitting images, thereby facilitating the
wireless transmission of digital camera images.
