Depth of field: Distance between the nearest and farthest points in a scene that are in focus as viewed by a particular lens. Affected by choice of lens focal length and iris aperture. Increases with both decreasing lens focal length and decreasing iris aperture.

Donpisha: Means "immediate" in Japaneese. CCD sensor shuttering technology for asynchronous shooting of fast moving objects without a time delay.

DSP (Digital Signal Processing): Inside a camera, sensor signals must be processed in several steps before they can be displayed/transmitted. Typical processing steps are amlification, gamma correction, black level correction, highlight compression/clipping, edge enhancement, color processing, color balance, color correction, output signal encoding. Picture qality is highly dependent on the accuracy and the stability of these processes. In DSP technology, the sensor signal is coverted to digital form after initial amplification, and all processing is achieved digitally, ensuring high quality and no drift. Output signals remain in digital form or are converted back to analog depending on the camera output mode.
