  • Patent number: 8466978
    Abstract: There is provided a digital image processor. An exemplary digital image processor comprises a pre-processor arranged to pre-process received digital images having a first resolution into a lower resolution to form pre-processed digital images. The pre-processor may be arranged to output the pre-processed digital images to a display independently from the received digital images being stored for subsequent post-processing. The exemplary digital image processor may also comprise a post-processor arranged to post-process received digital images that have been stored for post-processing.

  • Patent number: 7903149
    Abstract: A digital image process for a digital camera contains a preprocessor and a postprocessor. The preprocessor can include, for example, a uniformity corrector, a sampling filter, a modulation transformer, and a ditherer. The postprocessor can include a color interpolator, an RGB reconstruction block, a digital compressor, and a color pattern data buffer. The digital image process is programmable to operate one or more of the processing blocks of one or both the preprocessor and the postprocessor for flexible programming that can adapt to the requirements of various digital camera designs or users.

  • Patent number: 6794218
    Abstract: An imaging device such as a CMOS image sensor has a cover attached to a standoff surrounding a micro-lens array. Standard wafer processing fabricates the standoff (e.g., out of photoresist) and attaches the cover. The standoff maintains a gap over the micro-lenses. An adhesive attaches the cover to the standoff and can be kept away from the micro-lenses by a barrier having a structure similar to the standoff. Particles in the adhesive can prevent the adhesive from squeezing out from between the cover and the standoff during attachment. The standoff (and barrier if present) can provide a vent to prevent pressure in the gap from causing distortion or damage. The shape of the vent can prevent particles from entering the gap. Cutting the attached cover exposes electrical connections and can use preformed grooves in the cover to allow cutting of the cover without damaging underlying circuit elements.

  • Patent number: 6715003
    Abstract: A photo service provider provides remote developing, printing, and delivery of photographic prints of digital images. In one embodiment, a handheld digital camera can send to the photo service provider one or more digital images with address information (e.g., one or more address image created in the camera) indicating destinations for the digital images or photographic prints. One or more additional images or instructions associated with the delivery addresses can indicate the size or quantity of the prints to be delivered. The camera can be coupled to a data communication network through which the camera directly sends the selected images to the photo service provider. At a server of the service provider, one or more photographic prints of the selected images are automatically printed, packaged, and sent to the delivery addresses.
