General Performance Specifications


	Horizontal Resolution		Horizontal resolution is the maximum number of individual picture elements that can be distinguished in a single scanning line. This measurement is used to characterize the horizontal video resolution corrected for the image aspect ratio, or to specify the resolution in the largest circle than can fit in a rectangular image. A 640 x 480 image would, for example, be specified as 480 horizontal lines.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Maximum Frame Rate		The maximum frame rate is the number of frames that can be captured in a unit of time, such as seconds.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Shutter Speed		The shutter speed is the time of exposure or light collection. Typically, it may be set across a wide range.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Quantum Efficiency		Quantum efficiency is the ratio of photon-generated electrons that a pixel captures to the photons incident on the pixel area. This value is wavelength dependent so that the given value for quantum efficiency is generally for the peak sensitivity wavelength of the CCD.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Fill Factor		Fill factor is the percentage of the sensor array that is actively used for image sensing. Some types of sensors (e.g., CMOS) have on-board amplifiers or other circuitry whose physical space reduces the fill factor.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

Imaging Technology


	Imaging Technology
	Your choices are...
	CCD		Charge coupled devices (CCDs) are light-sensitive silicon chips that detect electrons excited by incoming light. They contain micro circuitry that transfers a detected signal along a row of discrete picture elements or pixels, scanning the image very rapidly. CCD cameras use two-dimensional CCD arrays with many thousands of pixels.
	CMOS		Complementary metal oxide semiconductor (CMOS) image sensors operate at lower voltages than charged coupled devices (CCDs), reducing power consumption for portable applications. Analog and digital processing functions can be integrated readily onto a CMOS chip, reducing system package size and overall cost. With CMOS, each active pixel sensor cell has its own buffer amplifier and can be addressed and read individually. Commonly used cells have four transistors and a photosensing element. Each cell has a transfer gate that separates the photosensor from a capacitive floating diffusion and a reset gate between the floating diffusion and the power supply. Each cell also has a source-follower transistor to buffer the floating diffusion from readout-line capacitance, and a row-select gate to connect the cell to the readout line. All of the pixels in a column connect to a common sense-amplifier.
	CID		Charge injection devices (CIDs) are photosensitive image sensors that are often implemented with large-scale integration technologies. CIDs can be randomly addressed, read non-destructively, and sub-scanned in a small region. CIDs are also less susceptible to charge overflows from bright pixels. To capture incident light, the pixel structure is contiguous with the maximum surface. This technique is also useful for sub-pixel measurements.
	Film		Images are exposed onto a photosensitive film that is developed. The shutter, a manual door that admits light to the film, typically controls exposure.
	Other		Other unlisted imaging technologies.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Format / Output



	Your choices are...
	USB		Universal serial bus (USB) is a 4-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. The USB design is standardized by the USB Implementers Forum (USBIF), an organization that includes leading companies from the computer and electronics industries. The current USB specification is USB 2.0, which supports data transfer rates of up to 480 Mbps.
	Wireless		Outputs are radio or wireless transmission.
	Other		Other unlisted, specialized, or proprietary configurations.
	IEEE 1394 (FireWire®)		IEEE 1394 or FireWire^® is an interface standard adopted by the Institute of Electrical and Electronics Engineers (IEEE) for very fast digital data transfers such as streaming video. IEEE 1394 connectors are used to transmit and receive data among FireWire devices, and are designed to replace external high-speed peripheral connections to personal computers, including hard disks, CD-ROMs, DVDs, graphics cards, high-speed scanners, direct video, monitors, etc. Tiny, robust FireWire connectors will also become important parts of home entertainment, communication, and appliance networks. FireWire is a registered trademark of Apple Computer, Inc.
	NTSC		The National Television System Committee (NTSC) 525-line color television standard is used in North America and Japan. Approximately 480 lines hold image information. The remaining lines contain synchronization, time delay, and other encoded information such as closed caption text. The standard frame rate is 30 frames per second.
	PAL		Phase alternate line (PAL) is a 625-line, 25-frame per second color television standard used in Europe. The phase of the color carrier is shifted 180° for each image line, making PAL less sensitive to color signal phase distortion. PAL provides lower vertical resolution than NTSC, but requires complex processing equipment.
	RS232		RS232 is an interface between data terminal equipment and data communications equipment that uses serial binary data interchange.
	RS422		RS422 is a balanced serial interface for the transmission of digital data. It was designed for greater distances and higher Baud rates than RS232.
	RS485		RS485 is a balanced serial interface for the transmission of digital data. The advantage of a balanced signal is a greater immunity to noise. The difference between RS422 and RS485 is that RS485 can be transformed into a multi-point application.
	Parallel		Parallel channels can transfer more than one bit simultaneously. They connect to a computer through a parallel port. Common protocols include standard parallel port (SPP) and enhanced parallel port (EPP). Centronics connectors are standard parallel interface devices for connecting printers and other peripherals such as portable disc drives, tape backup drives, and CD-ROM players to computers.
	Ethernet		Ethernet is a local area network (LAN) protocol that uses a bus or star typology and supports data transfer rates of 10 Mbps. The Ethernet specification is the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. To handle simultaneous demands, Ethernet uses carrier sense multiple access / collision detection (CSMA/CD) to monitor network traffic. This includes fast ethernet and gigabit ethernet.

Performance Features


	Anti-blooming		Saturation occurs when the light that is sensed exceeds a pixel's capacity to emit electrons. Excessive charge can bleed into adjacent pixels and cause bright spots or streaks to appear on the image, a condition known as blooming. Anti-blooming gates remove excessive charge and can significantly reduce blooming, but often at the cost of reduced sensitivity.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Auto-Lens		Auto-lens operation is a mode in which the lens iris automatically adjusts to maintain a predetermined level of light on the image pickup device. Cameras with auto-lens mode may also provide automatic lens focusing.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Cooled Sensor		Sensors are actively cooled by a Peltier element or other method. Cooling reduces “dark current” noise.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Gain Control		Automatic gain control (AGC) uses electronic circuitry to increase video signals in low-light conditions. This can introduce noise and, subsequently, graininess in the picture. Typically, AGC is disabled and specifications are presented with this feature turned off.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Gamma Correction		Gamma is the nonlinear relationship between the video signal level and the subsequent image element brightness.
