Camera Technology

ptical Technology 
Lights are supposed to be directed onto a sensor to reproduce the image. Each colour of lights has different wavelengths. If the lens cannot direct lights accurately onto the sensor, there will be imperfections, which adversely affect the sharpness and colour accuracy of the produced picture.

Canon is able to correct the various aberrations by producing aspherical lens that are made from fluorite or UD glass lens. She has also devised a system of positioning additional lenses with unique shapes in strategic places to eliminate additional aberrations that might occur during the zooming process.

Aspherical lens can reproduce images more accurately

Sensor Technology 
The CCD is a monochrome device. It needs a colour filter to produce a colour image. Each primary colour (eg red, green and blue) is placed on an individual pixel. The coloured filter then filters out all but the chosen colours for that pixel. The camera then combines the coloured pixel with its neighbouring pixels to produce the final image.

Traditionally, images are produced using traditional cyan-yellow-green-magenta colour filter. However, they are generally lacking details and intensity. Canon has overcome this shortcoming by using a green-red-green-blue filter, which produces richer and more natural colours. 

Digital Imaging Technology 
What is Digital Imaging Processor?
It's a chip that develops the image inside the digital camera.

What's so special about Canon's DIGIC (put logo) Image Processor.
DIGIC (Digital Imaging Core) is a "specialised" and "dedicated" chip to develop images for digital cameras. It's a first-of-its kind processor that puts six key elements important in a digital camera into one chip: - CCD control, Auto Exposure/Auto Focus/ Auto White Balance, Signal processing, JPEG compression/ expansion, memory card control and Display (colour LCD, video output)

With several new algorithms added, DIGIC gives stunning image quality, super-fast processing speed with large-capacity buffering and low power consumption.
How stunning image quality is achieved?
DIGIC ensures that no noise (Tiny white dots or streaks in pictures) is created when the image is captured and gives a wider dynamic range (range between brightest and darkest part of an image).
How super fast processing speed with large-capacity buffering is achieved.
Being a "dedicated" processor for digital camera, DIGIC has a shorter processing time. Therefore images are saved into a memory card at a fast speed, thus freeing the buffer capacity of the digital camera and allowing more shots to be taken.
