CHDK
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 A590 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. More recent models generally do not support remote capture. Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Custom Firmware
Custom firmware, also known as aftermarket firmware, is an unofficial new or modified version of firmware created by third parties on devices such as video game consoles and various embedded device types to provide new features or to unlock hidden functionality. In the video game console community, the term is often written as custom firmware or simply CFW, referring to an altered version of the original system software (also known as the official firmware or simply OFW) inside a video game console such as the PlayStation Portable, PlayStation 3, PlayStation Vita/PlayStation TV, PlayStation 4, Nintendo 3DS and Nintendo Switch. Installing custom firmware typically requires bootloader unlocking. Video game consoles Custom firmware often allow homebrew applications or ROM image backups to run directly within the game console, unlike official firmware, which usually only allow signed or retailed copies of software to run. Because custom firmware is often associated with softw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DDR-SDRAM
Double Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) class of memory integrated circuits used in computers. DDR SDRAM, also retroactively called DDR1 SDRAM, has been superseded by DDR2 SDRAM, DDR3 SDRAM, DDR4 SDRAM and DDR5 SDRAM. None of its successors are Forward compatibility, forward or Backward compatibility, backward compatible with DDR1 SDRAM, meaning DDR2, DDR3, DDR4 and DDR5 memory modules will not work in DDR1-equipped motherboards, and vice versa. Compared to single data rate (Synchronous dynamic random-access memory#SDR, SDR) SDRAM, the DDR SDRAM External memory interface, interface makes higher transfer rates possible by more strict control of the timing of the electrical data and clock signals. Implementations often have to use schemes such as phase-locked loops and self-calibration to reach the required timing accuracy. The interface uses double data rate, double pumping ...

JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/ Exif is the most common image format used by digital cameras and other photographic image capture devices; along with ...

Megapixels
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

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&nbs ...

SD Memory Card
Secure Digital, officially abbreviated as SD, is a proprietary format, proprietary non-volatile memory, non-volatile Flash memory, flash memory card format developed by the SD Association, SD Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCard, MultiMediaCards (MMCs), and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. History 1999–2003: Creation In 1 ...
