Canon digital camera innovations have always been at the forefront of photographic innovations and their compact digital cameras package a variety of functions into a deceptively small Canon digital camera body. These are particularly attractive to a wide range of users because of their light weight, ease of use, high image quality and high functionality. Canon digital camera experts are highly experienced in camera manufacturer, leading-edge optical technology, ultra high-precision mounting technology, electronic device technology and color management technology amongst others. All of this experience and expertise is combined to produce the Canon digital camera PowerShot series and the PowerShot DIGITAL ELPH/DIGITAL IXUS series.

Throughout their continuing research, the Canon digital camera development team has collected a large amount of photographic data and also made broad statistical analyses of the frequency involved in taking photographs. This data led to the creation of the Canon digital camera Photographic Space which is a graphical database of information relating to the relationship between surrounding brightness and distance between a Canon digital camera and the subject relative to the focal length and position of the zoom lens when pictures are taken.

The Canon digital camera Photographic Space led to the development of a new scene-recognition technology called "iSAPS" (intelligent Scene Analysis based on Photographic Space) Technology. Canon digital camera iSAPS Technology analyses the scene to be photographed and makes optimal adjustments of a number of key functions, including auto-focus, before the shutter is pressed.

The Canon digital camera iSAPS Technology closely estimates the camera-to-subject distance based on the lens focal length, zoom position and surrounding brightness which guarantees the most accurate exposure and white balance settings for the overall conditions.

At the high end of the Canon digital camera range are their single-lens reflex, or SLR, cameras. The Canon digital camera company has created ultra-high-precision imaging elements and high-performance digital imaging engines so that their digital SLR cameras possess the same ease of operation as their 35mm film counterparts but produce exceptionally high-quality images.

The Canon digital camera imaging engine, or DIGIC II, creates image data from signals output from a CMOS, or complementary metal oxide semiconductor, sensor. The CMOS sensor is really the brain of any digital camera. Canon developed the Canon digital camera DIGIC II high-performance imaging engine directly due to the increasingly high resolution CMOS sensors. With the help of a high-capacity DDRS DRAM (double data rate SDRAM) as the buffer memory, the Canon digital camera DIGIC II processes high-resolution images at ultra-high speeds.
