24.08.2011      THE JPEG 2000 STANDARD

The JPEG 2000 standard will appear in two parts. Part I will contain technologies used by all decoders. Part II will contain technologies which will serve some additional applications, but are viewed as adding too much complexity to be required of all JPEG 2000 decoders. A block diagram of a JPEG 2000 coder and the correspondence with the Annexes of the working draft of the standard appears in... read full

14.08.2011      CMOS-sensor

CMOS (complementary-symmetry the metal-oxide-semiconductor) sensor - a photoelectric device based on an array of photosensitive elements for converting incident light beam into an output analog electrical signal. The transformation is actualized through a large number of photodiodes and amplifiers located in the plane of the matrix cells (called pixels). Single element is sensitive throughout the visible spectral range, so over the photodiodes color CMOS image sensor uses a light filter that passes only one of three colors... read full

25.07.2011      USB 2.0 3.0, Gigabit Ethernet, Camera link

USB (Universal Serial Bus) is an industry standard developed in the mid-1990s that defines the cables, connectors and protocols used for connection, communication and power supply between computers and electronic devices. USB was designed to standardise the connection of computer peripherals, such as keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices... read full
