Canon is a leading provider of consumer, business-to-business, and industrial digital imaging solutions.
The adjustable aperture of the lens. It restricts the amount of light allowed into the camera. This term can also be applied to shutter types, i.e. iris diaphragm shutter, which is a set of interposing leaves, which open and close at a variable rate to produce a between-the-lens shutter.

Digital Print Order Format (DPOF) is a standard format control file that is stored in the digital still camera's removable memory card, which specifies which image files should be printed, and the number of copies.

Unlike an optical zoom, the digital zoom takes the central portion of the high-resolution sensor's image to achieve the effect of a zoom. This means that the existing data is not enhanced or added to, merely displayed at a lower resolution, thereby giving an illusion of an enlarged image. All PowerShot cameras utilize the superior optical zoom, which actually augments the data collected by the sensor, rather than merely creating the illusion that the image has been enlarged.
Industry:Consumer electronics
The ability of the camera's CCD to capture a full range of shadows and highlights.

Renowned for ultra fast, ultra quiet, precision autofocus. Each Canon EF lens has its own microprocessor controlled focusing motor for optimum performance. Many utilize Canon's exclusive Ultrasonic Motor technology.
Industry:Consumer electronics
The act of sending a file out through a specialized mini-application or plug-in so as to print or compress it. The term is also used to describe the action of saving the data to a specialized file format, i.e. JPEG, or GIF89a.
Industry:Consumer electronics
Exposure explains how light acts on a photographic material. The lens opening controls light intensity, while the duration is controlled by the shutter speed. A camera with autoexposure can automatically control the exposure. The same principle works with digital cameras where film is replaced by the CCD.
Industry:Consumer electronics
A system that allows "dialing-in" or adding or subtracting evaluation values (EV) for a given image. Compensating involves deciding whether or not the meter reading is under or over exposing and correcting the error. This method allows bringing out details in dark zones or lessening the intensity of bright zones, raising image quality.
Industry:Consumer electronics
The way an image is saved to a digital camera's memory. The . JPEG format that PowerShot cameras store digital images as is fast becoming an industry standard.
