Image Sensor
An image sensor or imager is a sensor that detects and conveys information used to make an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, camera phones, optical mouse devices, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. As technology changes, electronic and digital imaging tends to replace chemical and analog imaging. The two main types of electronic image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor). Both CCD and CMOS sensors are based on metal–oxide–semiconductor (MOS) technology, with CCDs based on MOS capacitors and CMOS sensors based on M ...

Canon EOS 350D
The Canon EOS 350D (Canon EOS Digital Rebel XT in North America and the Canon EOS Kiss Digital N in Japan) is an 8.0-megapixel entry-level digital single-lens reflex camera manufactured by Canon. The model was initially announced in February 2005. Part of the EOS range, it is the successor to the EOS 300D and the predecessor to the EOS 400D (or Digital Rebel XTi), which was released in August 2006. Details The 350D is an upgraded version of the Canon EOS 300D, which was the first sub-US$1000 digital SLR, introduced in 2003. There are some differences between the 350D and the 300D. Many of the features 'locked out' by Canon in the 300D were unlocked in this camera, so it has been subject to less unofficial 'hacking' to release the locked features. In addition to these unlocked features, a number of other improvements have been made. Some of the most significant upgrades include: * 8.0 megapixels (up from 6.3) * DIGIC II image processor * Faster power on times (0.2 seconds) * Co ...

Firmware
In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems (running embedded software), home and personal-use appliances, computers, and computer peripherals. Firmware is held in non-volatile memory devices such as ROM, EPROM, EEPROM, and flash memory. Updating firmware requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Some firmware memory devices are permanently installed and cannot be changed after manufacture. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Battery Sizes
This is a list of the sizes, shapes, and general characteristics of some common primary and secondary list of battery types, battery types in household, automotive and light industrial use. The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery. The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per cell) and the number of cells in the battery. For example, a CR123 battery is always LiMnO2 ('Lithium') chemistry, in addition to its unique size. The following tables give the common battery chemistry types for the current common sizes of batteries. See Electric battery#Comparison, Battery chemistry for a list of other electrochemical systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nikon D100
The Nikon D100 is a discontinued 6-megapixel digital single-lens reflex camera made by Nikon Corporation and designed as a consumer alternative to the professional D1 series cameras. It was the precursor of both the more advanced D70 and D200 cameras with the former continuing the consumer offerings and the latter beginning an advanced consumer and professional lineup. The D70 kept the controls which the D100 inherited from the F80 film camera, which has evolved into the current D7500 and D750 offerings, in cropped frame and full frame respectively. The D200 adopted the controls of the D1 series. History and Design It was introduced on February 21, 2002 at the Photo Marketing Association Annual Convention and Trade Show as a direct competitor to the Canon EOS D60. With a price of US$1,999 for the body only in the United States, it was the second 6-megapixel DSLR to break the $2000 barrier, after the EOS D60. Although the name D100 suggested that it was a digital version of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 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 Histor ...

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 Photographic printing, 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 file format conversion, 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 Negative (photography), negatives", but neither are they negatives nor do the unprocessed files constitute visible images. Rather, the Raw datasets are more like Exposure (photography), exposed but Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
