KODAK Camera Back and Imager
The KODAK camera back incorporates a charge coupled device (CCD)
The Specifications appendix lists the camera models available and dimen- sions of the imager and size of the file produced by the imager.
Just after you take a picture, the Canon
When you take a picture, light passes through the lens onto the imager; each pixel in the imager receives and stores a specified amount of light. These data — for one image — leave the imager chip in analog form, and are converted to digital form and stored with other data in dynamic random access memory (DRAM). The amount of DRAM in the camera is listed in the Specifications appendix.
Once the data are in DRAM, the data from the image are transferred to the PCMCIA card. Hardware in the camera back generates a thumbnail from the image data. The thumbnail is a subsample of image data. The thumb- nail is then stored with the full image on the PCMCIA card.
You can use one of the supplied software drivers on your computer to update firmware (nonvolatile memory) in the camera back that controls how the camera works. This is a key feature since this design means it is possible for you to update camera firmware yourself as it may be released by Kodak instead of returning the camera for firmware updates.
