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. As each photodiode records the color information for exactly one pixel of the image, without an image processor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Live-preview Digital Cameras
Live preview is a feature that allows a digital camera's display screen to be used as a viewfinder. This provides a means of previewing framing and other exposure before taking the photograph. In most such cameras, the preview is generated by means of continuously and directly projecting the image formed by the lens onto the main image sensor. This in turn feeds the electronic screen with the live preview image. The electronic screen can be either a liquid crystal display (LCD) or an electronic viewfinder (EVF). Background The concept for cameras with live preview largely derives from electronic (video) TV cameras. Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism. The first digital still camera with an LCD for autogain framing live preview was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nikon D4s
The Nikon D4S is a full frame professional DSLR camera announced by Nikon Corporation on February 25, 2014 to succeed the D4 as its flagship DSLR. The D4S offers a number of improvements over its predecessor including a new image sensor, new image processor, new battery, improved ergonomics and expanded ISO range. Additionally, improved auto focus (AF) algorithms and a new AF Tracking mode were introduced together with a new option of RAW image capture in full resolution (16MP) or a "Small" file (4MP). In May 2014, the D4S received a Technical Image Press Association (TIPA) 2014 Award in the category of "Best Digital SLR Professional". In August 2014, the D4S received a European Imaging and Sound Association (EISA) award in the category "European Professional DSLR Camera 2014-2015". The D4S was superseded by the Nikon D5, announced on January 6, 2016. The D4S was discontinued in December 2016. Features While the D4S retains many features of the Nikon D4, it offers the f ...

International Space Station
The International Space Station (ISS) is a large space station that was Assembly of the International Space Station, assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), European Space Agency, ESA (Europe), JAXA (Japan), and Canadian Space Agency, CSA (Canada). As the largest space station ever constructed, it primarily serves as a platform for conducting scientific experiments in microgravity and studying the space environment. The station is divided into two main sections: the Russian Orbital Segment (ROS), developed by Roscosmos, and the US Orbital Segment (USOS), built by NASA, ESA, JAXA, and CSA. A striking feature of the ISS is the Integrated Truss Structure, which connect the station’s vast system of solar panels and Spacecraft thermal control, radiators to its pressurized modules. These modules support diverse functions, including scientific research, crew habitation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autofocus
An autofocus (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. Autofocus accur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HDMI
High-Definition Multimedia Interface (HDMI) is a proprietary digital interface used to transmit high-quality video and audio signals between devices. It is commonly used to connect devices such as televisions, computer monitors, projectors, gaming consoles, and personal computers. HDMI supports uncompressed video and either compressed or uncompressed digital audio, allowing a single cable to carry both signals. Introduced in 2003, HDMI largely replaced older analog video standards such as composite video, S-Video, and VGA connector, VGA in consumer electronics. It was developed based on the CEA-861 standard, which was also used with the earlier Digital Visual Interface (DVI). HDMI is electrically compatible with DVI video signals, and adapters allow interoperability between the two without signal conversion or loss of quality. Adapters and active converters are also available for connecting HDMI to other video interfaces, including the older analog formats, as well as digital fo ...
