DIGIC
Digital Imaging Integrated Circuit (often styled as "DiG!C") is Canon Inc.'s name for a family of signal processing and control units for digital cameras and camcorders. DIGIC units are used as image processors by Canon in its own digital imaging products. Several generations of DIGICs exist, and are distinguished by a version number suffix. Currently, DIGIC is implemented as an application-specific integrated circuit (ASIC) designed to perform high speed signal processing as well as the control operations in the product in which it has been incorporated. Over its numerous generations, DIGIC has evolved from a system involving a number of discrete integrated circuits to a single chip system, many of which are based around the ARM instruction set. Custom firmware for these units has been developed to add features to the cameras.

Canon PowerShot S1 IS
The Canon PowerShot S is a series of digital cameras released by Canon, as part of the wider PowerShot range. The S-series was originally a line of compact point-and-shoot cameras, slowly evolving into a prosumer line of cameras slotting right beneath the G-series cameras. The line later branched off into Canon's line of super-zoom cameras. The PowerShot ELPH line is a branch of the S-series, due to its model number designations in the United States (with the S- and SD- prefixes), as well as the similarities between the PowerShot ELPH S100 and the PowerShot S10 G-series in a compact body From the PowerShot S90 onwards the S-series continues a line of Canon compact digital cameras that commenced with the Ixus 900Ti and feature the Digic image processors and larger than average sensors as fitted to the advanced PowerShot G-series cameras. The Ixus / S-series and the equivalent G-series models are listed below: * Ixus 900Ti (SD900)* / PowerShot G7 / Digic III / 10MP 3648 × 2736 ...

Canon PowerShot A720 IS
The Canon PowerShot A is a now discontinued series of digital cameras released by Canon. The A-series started as a budget line of cameras, although over time its feature set varied from low-end point-and-shoot cameras to high-end prosumer cameras capable of rivalling Canon's G-series. Models The series began with the A5 series, which was a very basic point-and-shoot camera line. The Axx series that followed offered full manual control (on most models) in a fairly bulky body. The A100/200/3xx/4xx series cameras are stripped-down with very little manual controls. The Axx series has branched off into the A5xx (replaced by the A1xxx series), A6xx, and A7xx series (the latter replaced by the A2xxx series). A-series camera are generally powered by 2 AA batteries. Features Software by Breezesys adds remote capture capability from a computer over the USB interface on early Canon PowerShot A models until around 2006.

Canon EOS 5D
The Canon EOS 5D is a 12.8 megapixel digital single-lens reflex (DSLR) camera body produced by Canon. The EOS 5D was announced by Canon on 22 August 2005, and at the time was priced above the EOS 20D but below the EOS-1D Mark II and EOS-1Ds Mark II in Canon's EOS digital SLR series. The camera accepts EF lens mount lenses. The EOS 5D is notable for being the first full-frame DSLR camera with a standard body size (as opposed to the taller, double-grip "professional" camera body style). It is also notable for its price, suggested at US$3299 without lens, which set a significant new low price point for full-frame DSLRs; its only full-frame competition at the time was the Canon 1Ds Mark II, which cost more than twice as much. On 17 September 2008, Canon announced the camera's successor, the Canon EOS 5D Mark II. Features Sensor and image processing The 5D has a DIGIC II processor and a 35.8 x 23.9 mm full-frame CMOS sensor with 13.3 million pixels (12.7 megapixel effecti ...

Canon EOS-1D Mark III
The EOS 1D Mark III is a professional 10.1 megapixel digital single lens reflex camera (DSLR) camera body produced by Canon. The EOS 1D Mark III was announced on February 21, 2007 and is the successor of the Canon EOS-1D Mark II N and was first released in May 2007. In late 2009, the camera was succeeded by the Canon EOS-1D Mark IV. One of the main benefits of the new Mark III, over the previous models, was the added functionality of Live view, allowing users to take pictures while looking at an LCD screen. While it had the same outdated software as the older 1D series cameras, it had a much improved button layout, which is still used today. It also had improved wireless capabilities (with the optional WFT-E2 wireless adapter) over the Mark II. The new WFT-E2 was much smaller than the previous WFT-E1 for the Mark II. The new transmitter could now also connect via a USB port. This allowed the optional addition of a GPS unit and wired PC connectivity. Features * 28.1 × 18.7&nb ...

Powershot A720is
The PowerShot products is a line of consumer and prosumer grade digital cameras, launched by Canon in 1996. () In 1996 a model of PowerShot was introduced to the market, The Powershot 600. The production of The PowerShort came shortly after Canon released and subsequently discounted its SV series in 1992 and switched to digital cameras. The PowerShot line has been successful for Canon, and is one of the best-selling digital camera lines worldwide. The Powershot's success comes its marketing to the general public as a compact and easy to use digital camera. Free software from the Canon Hack Development Kit (CHDK) project allows nearly complete programmatic control of PowerShot cameras, enabling users to add features, up to and including BASIC and Lua scripting. Some models of PowerShot cameras were affected by third-party CCD sensors with a design flaw, which caused them to fail and display severely distorted images. Canon offered to repair affected cameras free of charge. Pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Processor
An image processor, also known as an image processing engine, image processing unit (IPU), or image signal processor (ISP), is a type of media processor or specialized digital signal processor (DSP) used for image processing, in digital cameras or other devices. Image processors often employ parallel computing even with SIMD or MIMD technologies to increase speed and efficiency. The digital image processing engine can perform a range of tasks. To increase the system integration on embedded devices, often it is a system on a chip with multi-core processor architecture. Function Bayer transformation The photodiodes employed in an image sensor are color-blind by nature: they can only record shades of grey. To get color into the picture, they are covered with different color filters: red, green and blue (RGB) according to the pattern designated by the Bayer filter - named after its inventor. As each photodiode records the color information for exactly one pixel of the image, withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autofocus
An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types. Autofocus systems rely on one or more sensors to determine correct focus. Some AF systems rely on a single sensor, while others use an array of sensors. Most modern SLR cameras use through-the-lens optical sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Through-the-lens optical autofocusing is usually speedier and more precise than manual focus with an ordinary viewfinder, although more precise manual focus can be achieved with special accessories such as focusing magnifiers.
