Canon PowerShot S100
The Canon PowerShot S100 is a high-end 12.1-megapixel compact digital camera announced and released in 2011. It was designed as the successor to the Canon PowerShot S95 in the S series of the Canon PowerShot line of cameras. The S100 is a similar camera to S90 and S95 with several significant improvements. It has improved noise reduction, white balance and shadow correction. This camera is the first camera in the S series line to use the CMOS Sensor which gives the camera a higher performance and better light sensitivity. The S100 is also the first camera in the series to feature 1080p video recording in 24 frames per second. Canon has acknowledged that some PowerShot S100 digital cameras encounter a lens error caused by a disconnected part inside the camera. This makes the camera unusable. Canon offered free repairs well beyond the warranty date, even if the camera has a serial number outside the range mentioned in the product advisory; however, this ended when they stopped ...

Canon PowerShot S90
The Canon PowerShot S90 is a high-end 10.0-megapixel compact digital camera originally announced in 2009. The PowerShot S90 is the successor of the Canon PowerShot S80. The almost 4-year gap between the S80 and the S90, compared with intervals of 6 months to 1 year between prior versions, led to the line being popularly considered discontinued, and thus the S90 as a revival, rather than a strict successor. Features * 10.0 megapixels * JPEG (Exif 2.2) support * Raw image file format; one of few "point and shoot" cameras to have raw formatting. (Note: Raw format is not available in Auto, Low Light, and SCN modes. Raw is available in Program, TV (shutter priority), Av (aperture priority), Manual, and Custom modes) * ISO sensitivity 80–3200 and auto. Low light mode can shoot up to ISO 12800. * Wide-angle zoom lens 6.0–22.5 mm (35 mm equivalent: 28–105 mm) * Full manual control * Customizable Control Ring to control ISO, shutter speed, aperture, focus, or exposu ...

Film Speed
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a ''slow film''. Highly sensitive films are correspondingly termed ''fast films''. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. Film speed measurement systems Hi ...

Raw Image Format
A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. Raw files are named so because they are not yet processed and therefore are not ready to be printed, viewed or edited with a bitmap graphics editor. Normally, the image is processed by a raw converter in a wide-gamut internal color space where precise adjustments can be made before conversion to a viewable file format such as JPEG or PNG for storage, printing, or further manipulation. There are dozens of raw formats in use by different manufacturers of digital image capture equipment. Rationale Raw image files are sometimes incorrectly described as "digital negatives", but neither are they negatives nor do the unprocessed files constitute visible images. Rather, the Raw datasets are more like exposed but undeveloped film which can be converted (electronically developed) in a non-destructive mann ...

Exchangeable Image File Format
Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras. The specification uses the following existing encoding formats with the addition of specific metadata tags: JPEG lossy coding for compressed image files, TIFF Rev. 6.0 ( RGB or YCbCr) for uncompressed image files, and RIFF WAV for audio files (linear PCM or ITU-T G.711 μ-law PCM for uncompressed audio data, and Interactive Multimedia Association, IMA-ADPCM for compressed audio data). It does not support JPEG 2000 or GIF encoded images. This standard consists of the Exif image file specification and the Exif audio file specification. Background Exif is supported by almost all camera manufacturers. The metadata tags defined in the Exif standard cover a broad spectrum: * Cam ...

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 ...

Megapixel
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. Etymology T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CMOS Sensor
An active-pixel sensor (APS) is an image sensor where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor. CMOS sensors are used in digital camera technologies such as cell phone cameras, web cameras, most modern digital pocket cameras, most digital single-lens reflex cameras (DSLRs), and mirrorless interchangeable-lens cameras (MILCs). CMOS sensors emerged as an alternative to charge-coupled device (CCD) image sensors and eventually outsold them by the mid-2000s decade. The term ''active pixel sensor'' is also used to refer to the individual pixel sensor itself, as opposed to the image sensor. In this case, the image sensor is sometimes ...

Canon PowerShot
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] |
Digital Camera
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras (which are still available). High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs. Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can al ...

Canon PowerShot S
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 S95
The Canon PowerShot S95 is a high-end 10.0-megapixel compact digital camera announced and released in 2010. It was designed as the successor to the Canon PowerShot S90 in the S series of the Canon PowerShot line of cameras. This model is considered high-end, professional, or prosumer because of its price, its feature set, and its high-sensitivity image sensor. Its 10-megapixel image sensor is larger than typical sensors found in point-and-shoot cameras. This, along with the advanced image stabilization system, allows for sharp images in lower light scenarios, at an ISO of up to 3,200. The S95 is similar to the S90, but adds a number of refinements. Among other things, it features a thinner body, improved image stabilization, an automated HDR shooting mode, 720p HD-quality video recording with stereo sound, and a more ergonomic finish and controls. Other features include a tracking autofocus function, enabling it to track and focus on moving subjects. Features * 10.0 mega ...
