CMOS Cameras Specifications

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.

Format / Output



	Your choices are...
	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.
	RS644 / LVDS		RS644 defines a differential signal, not a specific voltage level. RS644 can use 1 V, 4 V, or 350 mV low-voltage differential signaling (LVDS).
	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.
	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.
	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.
	Camera Link^®		Camera Link^®, a registered trademark of the Automated Imaging Association, is a communication interface for vision applications. It extends the base technology of CHANNEL LINK, a chipset that supports high-speed, point-to-point data transmission.
	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.

Features


	Performance
	Your choices are...
	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.
	Auto-Lens Operation		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.
	Automatic Gain Control (AGC)		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.
	Board Mount		Camera optics are mounted directly on a printed circuit board (PCB). Often, PCBs are components of larger devices.
	Cooled Sensor		Sensors are actively cooled by a Peltier element or other method. Cooling reduces “dark current” noise.
	Dome		Cameras are enclosed in a protective dome made from materials such as acrylic or polycarbonate. Typically, these materials are optically corrected for accurate image capture.
	Electronic Shutter		Electronic shutter control refers to the light gathering period. This may be programmed or altered with a digital electronic interface.
	External Trigger Input		Image capture can be initiated, stopped, or controlled by an external event or trigger.
	Gamma Correction		Gamma is the nonlinear relationship between the video signal level and the subsequent image element brightness. Gamma correction compensates for this nonlinearity in order to render the image true in color while providing intensity to the original object. For the purposes of this search form, cameras that can turn Gamma correction on and off are considered to include this feature.
	Outdoor Rated		Outdoor rated devices are designed to withstand outdoor temperature variations, rain, snow, and other weather conditions.
	Pan / Tilt		Pan or tilt devices have integral or optional mounting features enabling side-to-side (pan) and up-and-down (tilt) controllable motion.
	Progressive Scan		Progressive scan is a CCD design that allows acquisition of both even and odd fields at the same time. Each pixel contains information from one complete frame. This technology allows high resolution without the use of a mechanical shutter. Progressive scan cameras are used for image acquisition of rapidly moving objects and accurate dimensional measurements.
	Radiation Hardened		Devices are designed to withstand high levels of radiation. These cameras can be used in nuclear facility applications.
	Underwater Rated		Devices are designed to work when completely submerged in water.
	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.
