Canon is a leading provider of consumer, business-to-business, and industrial digital imaging solutions.
A digital image storing mechanism that is increasing in popularity and thus functionality. Flash memory is a safe, highly reliable form of storage that doesn't need power to hold the images after they are saved. It won't erase the images unless the user chooses to do so.
Industry:Consumer electronics
If two colors, combined in the proper proportion form white light, then they are complimentary colors.
Industry:Consumer electronics
The difference between elements in a photograph. Contrast can include the difference between light and dark areas, or a marked difference in colors.
Industry:Consumer electronics
A.k.a. noise, dark noise. Pixels collect signal-charges in the absence of light over time, which can vary from pixel to pixel, and the result is known as dark current. PowerShot digital cameras reduce or eliminate dark current before a picture is captured.
Industry:Consumer electronics
The zone of in-focus elements, from front to back. Another way to put this is the range of distance that is acceptably sharp within a photograph. Depth-of field varies inversely with the aperture opening. In other words, a wide-open lens with an aperture of f/1.8 has little depth of field; if stopped down to f/16, almost everything from front to back will be sharply in focus.
Industry:Consumer electronics
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.
Industry:Consumer electronics
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.
Industry:Consumer electronics
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 utilise 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.
Industry:Consumer electronics
Renowned for ultra fast, ultra quiet, precision autofocus. Each Canon EF lens has its own microprocessor controlled focusing motor for optimum performance. Many utilise Canon's exclusive Ultrasonic Motor technology.
