DCS 465 Camera Back and Imager

The KODAK camera back incorporates a charge coupled device (CCD) full-frame imager that collects light resulting in a file containing 6.0 megabytes of data. There are two versions of the imager, one in the color camera back, and another in the monochrome camera back. The CCD imager is 18.4 mm x 27.6 mm. This produces a field of view equal to using a lens with 1.3 times the focal length of the lens in use.

3060 pixels

2036 pixels

When you take a picture, light passes through the lens onto the imager; each pixel 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).

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, with data sampled from every sixteenth pixel. The thumbnail is subsequently stored with the full image on the PCMCIA card.
