Making Possible High-Speed, High-Precision Control
iSAPS Technology
"Photographic Space" Database
(Analysis of subject position based on a given focal length)
Over many years of camera development, Canon has collected a huge volume of photographic data and made extensive statistical analyses of the correlation between focal length and zoom settings, and surrounding brightness and subject-to-camera distance. Based on this data, Canon developed iSAPS (intelligent Scene Analysis based on Photographic Space) technology, which envisages the scene to be photographed and selects optimal settings of key functions.
As the user prepares to take a picture, iSAPS estimates the subject-to-camera distance based on the focal length, zoom position and surrounding brightness. It also estimates the camera-to-subject distance by factoring in parameters based on previous shots. iSAPS High Speed AF predicts in advance the focus position based on previously analyzed scenes. Since a correction of the pre-estimated position is all that's needed at the time of actual shooting, less time is required for focusing. iSAPS Intelligent AE/AWB applies optimal algorithms for each shot according to the shooting mode selected by the user, assuring fewer mistakes thanks to more precise exposure and white balance commensurate with the selected mode and surrounding environment.
Real-Time Embedded Operating System for Higher Product Functionality and Performance
DRYOS
DRYOS is the name of a real-time operating system (OS) developed exclusively by Canon and employed in the system LSI for its digital video camcorders.
A major feature of DRYOS, which has a kernel module at its core, is its flexible structure, which can be expanded from as small as 16 kilobytes, facilitating customization to the needs of the target device and hardware resources. Canon also developed a USB- and middleware-compatible device driver for file systems and network functions to meet the needs of increasingly diversified digital products.
DRYOS is currently compatible with more than 10 CPU types, and also provides a simulation-based development environment for debugging. By developing platform software in-house, Canon can more effectively promote reuse and sharing of software modules while raising product functionality and quickly addressing the trend toward highperformance devices.

Fitting a 3x Optical Zoom Inside a Compact Body
Ultracompact Lens Unit
PowerShot SD600 DIGITAL ELPH Lens Unit
Canon's PowerShot DIGITAL ELPH (DIGITAL IXUS) series digital cameras package high image quality and high functionality in a compact body. Their slim and lightweight bodies are made possible by the development of an ultracompact lens unit utilizing Canon's advanced optical technologies.
For example, the PowerShot SD600 DIGITAL ELPH (DIGITAL IXUS 60) incorporates a 3x optical zoom lens with a focal length of 5.8-17.4 mm (equivalent to 35-105 mm in 35 mm film format) within a space measuring 20.2 mm in depth. The lens unit employs two proprietary glass-molded (GMo) UA (Ultra high refractive index Aspherical) lens elements within a five-group/six-element configuration. Since UA lenses have a significantly higher refractive index than ordinary aspherical lenses, the lens unit could realize an unparalleled compact size. Revising the aperture, shutter and lens-barrel structure also contributed to the achievement of a smaller lens unit. The total size of lens unit is small enough to fit onto a one-cent euro coin (16.25 mm in diameter).
But this ultracompact lens unit isn't just small. In addition to an aspherical lens element, it incorporates an optimal combination of lenses with various optical characteristics, such as two lenses with different optical characteristics bonded together, to deliver the clear, sharp images that are the hallmark of Canon camera lenses.
 |  | Multiple Point AiAF |
Canon's wide-area AiAF (Artificial Intelligent Auto-Focus) intelligently and automatically selects one or more focusing points based on factors, such as subject position and motion. AiAF works in conjunction with iSAPS Technology to more quickly and accurately achieve auto-focus under a wide variety of shooting conditions. You get fast, accurate AF whether you hold the camera horizontally or vertically, with stationary or moving subjects, with off-center subjects, and even in low-light/low-contrast lighting. Simply place the subject anywhere in the frame and the wide-area multiple-point AiAF automatically selects any of the focus points. Out-of-focus pictures when the subject isn't centered are a thing of the past.
 | | Optical Image Stabilizer |  |
If all your pictures were taken outdoors on a bright, sunny day you may not find it difficult to capture sharp pictures. But blurred pictures due to camera shake becomes more of a problem when taking pictures in dim light - at dusk, indoors, on a cloudy day. And the chance of getting blurred pictures increases when using longer focal length lenses that magnify the image and any associated movement.
| To overcome these problems, Canon developed lenses with built-in image stabilization. The Canon Image Stabilizer uses sensors to detect motion and generate a corrective signal to reduce blur caused by camera movement. An image-stabilizing lens group along the optical axis is shifted in response to the detected motion, providing effective cancellation of unwanted lens movement and vibration. Result – in still photography, high magnification lenses can be hand-held at slower shutter speeds without blurred images, and handheld video footage is smoother. In many shooting situations where photographers are not allowed to use a tripod or flash, such as art museums and concert halls, Canon lenses with image stabilization are the ticket to sharper pictures. | |  |
