    Abstract: PROBLEM TO BE SOLVED: To provide a DSC (Digital Still Camera) system capable of reducing the configuration and energy consumption and producing an image with a small loss on a network. SOLUTION: A digital camera includes: a sensor 205 for sensing an image and producing a first signal; a Bayer pattern producer 210 coupled to the sensor and structured to produce a Bayer pattern from the first signal; a splitter 212 that splits the Bayer pattern into separate color channels; a compressor 220 for compressing the color channels into a compressed image; and an output interface 226 for transmitting the compressed image over a communication channel. The digital camera also includes: a color interpolator 214 that is structured to perform a modification on each of the color channels produced by the splitter 212 prior to transmission of the color channels to the compressor 220. A multimedia packer 222 packs multimedia data in a unique format and transmits the result to the output interface 226 to be connected to a wireless network. COPYRIGHT: (C)2003,JPO

    Abstract: Presented is a digital camera, comprising: a sensor (205) for sensing an image and producing a first signal; a Bayer pattern producer (210) coupled to said sensor (205) and structured to produce a Bayer pattern from said first signal; a splitter (212) structured to split said Bayer pattern into separate color channels; a compressor (220) for compressing said color channels into a compressed image; an output interface (226) structured to transmit said compressed image on a communication channel; and a color interpreter structured to perform a modification on exactly one of said color channels from said splitter (212) prior to sending said color channels to said compressor (220). Additionally described is a network that operates with said digital camera to perform certain functions, as directed by a user of said digital camera.

    Abstract: A fast method of color interpolation of pixels of an image acquired by a color filtered digital sensor uses a very simple cost function that nevertheless produce interpolated images of good quality. The cost function is computationally simpler because it does not require the calculation of powers and square roots. An efficient triangulation algorithm that may be executed in far less time than prior art triangulation processes, while practically ensuring the same performances. The peculiarity of this triangulation algorithm consists in that on average it requires only two iteration steps, while the most accurate prior triangulation algorithm is completed only after four iteration steps. Optionally, the interpolation process may be followed by an anti-aliasing processing that effectively removes color artifacts that may be created during the interpolation process.
