Digital Compact Cameras
Advanced Technologies for Compact Design and High Image Quality
Canon's digital compact cameras are highly regarded for their high image quality, high performance, convenience and ease of use. The body incorporates the latest technology such as optical technology that the company has developed as a camera manufacturer.
How a Digital Compact Camera Works
A digital compact camera is made up of optics such as the lens and aperture, and electronics such as the image processor, the image sensor and the LCD display. Light that passes through the lens is converted into a digital signal by the image sensor (CCD sensor or CMOS sensor) that is equivalent to film in a silver halide camera, and this undergoes a variety of image processing in the imaging processor to produce a beautiful image. This is then recorded on the memory card.

Digital SLR Cameras
Overcoming Challenges to Achieve Rich Expressive Capabilities
Since Canon was founded, the company has sought to produce the ideal SLR camera. The company leads the world with its innovative products that produce high-quality images using groundbreaking technologies such as lenses, CMOS sensors and image processors
How a Digital SLR Camera Works
Light that passes through the lens is reflected by the mirror, and the image displayed on the focusing screen positioned at the same distance from the mirror as the focal plane, is refracted by the pentaprism to be viewed in the viewfinder. When the shutter button is pressed, the mirror flips up and the light directly reaches the image sensor without being refracted. It is possible to take a diverse range of photos by interchanging the lens.

Digital Camcorders
Opening Up the High-Image-Quality World of HD Video
Digital video images require advanced digital imaging technology that differs from that used for photography. Canon produces advanced full-HD video camcorders that realize high-speed data processing, compact size and low power consumption.
How a Digital Camcorder Works
Light that enters through the lens is converted into digital data by the image sensor (CCD sensor or CMOS sensor). This is made into high definition video by the image processor, compressed by the codec engine, and stored in the memory. Audio is converted into an electric signal by the microphone, and similarly stored in the memory. In addition, because consumer digital camcorders are often used while held in the hand, they are equipped with high-performance image stabilizers.
Scanners
High-Precision Scanning Technology Expanding the Range of Digital Data Use
Canon, which has worked to develop high-precision scanning technology, has combined many of its unique advanced optical, electronics, and software technologies to create scanners that enable the conversion of camera film, photo prints, and text documents into high-grade digital data.
How a Scanner Works
A scanner converts documents (including camera film, photo prints, and text documents) into digital data by exposing them to light to form an image that is "read" by an image sensor. CCD models incorporate high-precision optics and high-density CCD line sensors that illuminate the document with a light source such as white LED to deliver sharp, high-resolution images. CIS scanners are slim-bodied, energy-efficient models that utilize a three-color RGB LED as the light source and read documents with a CIS (Contact Image Sensor) of the same width as document originals.
Broadcasting Equipment
In addition to HDTV (High-Definition Television) broadcast lenses and network cameras etc., Canon has developed a next-generation Super Hi-Vision (SHV) television broadcast lens which effectively meets the demands of professional users.
Network Cameras
Overwhelmingly High Image Quality and Advanced Monitoring
Canon's network cameras integrate optical technologies with the image processing and network distribution technologies developed by Canon for high image quality, high functionality, and high performance.
How a Network Camera Works
The image sensor in a network camera converts light rays passing through the lens system into digital signals. Next, the image processor converts the digital signals into high-definition images, which are then sent to PCs connected to a network using the image-compression and communication engine. Users can remotely control the camera's direction and zoom view while internal intelligent functions detect various changes in a scene.
Medical Equipment
Canon uses its original optical and digital imaging technologies to supply devices that support digitization and networking in the field of medicine, such as digital X-ray systems and ophthalmic equipment.
