Image sensor

The LBCAST (Lateral Buried Charge Accumulator and Sensing Transistor array) developed by Nikon realises a new concept in image sensors.

Image sensor sizes range from the tiny up to ones as large as a frame of 35mm film-called a full frame sensor. Click to explore the sizes of image sensors. Click here for a PDF extension on pixels and read Part 1 on aspect ratios.

Image sensor An image sensor is a type of transducer (an electronic device that converts one type of energy to another).

Image Sensor The image sensor is the equivalent of 'film'. An image sensor contains millions of pixels (megapixels) arranged in a matrix whose job is to catch and record light when you take a picture.

Image sensor The type of device used in digital camera and camcorders to capture an image. The 2 most common types are known as CCD (charge-coupled device) and CMOS (complementary metal oxide semiconductor) ...

Image sensors used by digital cameras frequently have a number of pixels on the edge which are masked off and which do not form part of the image.

Image sensor created using a Complementary Metal-Oxide Semiconductor (CMOS). CMYK: ...

Image sensor. A solid-state device containing a photosite for each pixel in the image. Each photosite records the brightness of the light that strikes it during an exposure. Infrared. See IrDA. International Organization for Standardization. See ISO.

Image sensor See sensor ISO ISO is a term "borrowed" from film photography. In film photography the ISO was a measure of how sensitive film was to light. It was called film speed.

Image Sensor Cleaning Vibrations at four different resonant frequencies remove dust from the optical low-pass filter in front of the image sensor.

Image sensors used in DSLRs come in a range of sizes. The very largest are the ones used in "medium format" cameras, typically via a "digital back" which can be used as an alternative to a film back.

Image Sensor The device which captures the image in a digital camera (CCD, CMOS, Foveon). Image Stabilisation ...

Image Sensor - An electronic device that uses light that flows through a digital camera lens in order to create an image. It is the digital version of traditional camera film.

Image Sensor. Digital cameras use an electronic image sensor (CCD or CMOS), to gather the image data, whereas a traditional camera exposes light to emulsion film, ...

Image Sensor - A traditional camera exposes a piece of light-sensitive film, digital cameras use an electronic image sensor to gather the image data. See "CCD" and "CMOS" as well as "Interlaced" and "Progressive Scan" ...

Common Image Sensor Sizes In the table below "Type" refers to the commonly used type designation for sensors, "Aspect Ratio" refers to the ratio of width to height, "Dia.

Nikon uses good image sensors and lenses which really make a difference compared to cheaper 2 megapixel cameras. Great beginner camera and a good choice if you're on a budget. Get the Nikon 2500, check the price here and read more here...

of "parts" of Toshiba to go around!) On the semiconductor side, Toshiba has long been a world leader in CMOS technology, and that capability was reflected in their first digital camera, in which all the camera electronics, including the image sensor, ...

CCD raw format The uninterpolated data collected directly from the image sensor before processing. Cepheid Variable A type of luminous giant star whose luminosity varies in a periodic fashion.

This variable waveform represents density and colors that are created electronically by the intensity and the color of light striking an image sensor within the camera.

The image sensor chip is an additional 44mm back from that. You thus effectively have a 36x24 sensor (43mm diagonal) at the end of 67mm tube.

An image sensor of about 1 square inch requires super excellent optics if the resulting images are going to be made into big prints.

The foremost factor distinguishing the Nikon FX format from other image sensors is the larger pixel size, which allows it to collect more light. The D3 features 12.1 effective megapixels, with a pixel size of 8.45 x 8.45µm - 2.

Earlier this year, a company called Foveon announced the world's first full-color image sensor. Image sensors in all digital cameras up till now actually only register either red, green or blue at each pixel, interpolating the remainder of the data.

It depends on the similarities between the image sensor system. A sensor SYSTEM contains the image sensor with or without micro-lenses, an IR filter, a low-pass (Moire) filter and the signal processing.

In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography - the lower the number the less sensitive your camera is to light and the finer the grain.

Digital single lens reflex cameras (DSLRs) combine the advantages of SLRs with the ones of digital cameras since they have an image sensor instead of a film in the image plane, and a digital image memory.

Raw files contain the actual digitized data from your camera’s image sensor. The data is a string of numerical brightness values straight from each red, green and blue photosite.

CCD: Charge Coupled Device: one of the two main types of image sensors used in digital cameras. When a picture is taken, the CCD is struck by light coming through the camera’s lens.

Adjusts the image sensor for the type of light under which you are photographing. Can be automatic or manual. It is easy to see that flourescent lights have a different color from incandescent lights.

Shutter speed is the time the shutter, which lets light onto the digital image sensor, remains open-or the time the image sensor is activated. If you're new to photography, look at it this way.

Shutter Speed - The length of time the image sensor is exposed to light anywhere from a few seconds (8s, 1s, etc.) to fractions of seconds (1/125, 1/500, etc.). You'll need a fast shutter speed to capture action.

The Standard IS 1 option offers both horizontal and vertical Image sensor stabilization, which is ideal for most low-light, handheld photography or when shooting in unstable conditions, like when you're in a car or on a boat.

A CCD image sensor is comprised of a grid of such photodiodes. A photodiode is a monochromatic device; ...

Large format, medium format, or 35mm, but determined by the actual dimensions of the focal plane or image sensor.

Note: many compact digital cameras use the image sensor itself as a contrast sensor (using a method called contrast detection AF), ...

For instance Fujifilm's Super CCD image sensor can capture "effective" pixels of 3.1 megapixels, but it's software interpolates them up to 6 megapixels.

A focal plane shutter exposes the image by moving two light-blocking curtains across the front of the image sensor. The first curtain slides open to begin the exposure, then the second curtain slide closed to terminate the exposure.

To move the lens or film/image sensor in order to record a sharp image. frame grabber: A photo-editing program tool used to move menus and palettes around on the screen.

A pattern of red, green, and blue filters on the image sensor's photosites. There are twice as many green filters as the other colours because the human eye is more sensitive to green and therefore green colour accuracy is more important.

Optical Zoom: Optical zoom lenses on a digital camera use all of the CCD image sensor's area to capture the image. Digital zoom essentially crops the image to deliver an apparent increased zoom effect but the trade-off is image quality.

Mechanical system used to control the time that light is allowed to act on a light sensitive emulsion or an image sensor. The two types most common on modern cameras are the between-the-lens diaphragm shutter and the focal plane shutter.

CMOS Complementary Metal-Oxide Semiconductor (CMOS). An image sensor used in some digital cameras. Its basic function is the same as the CCD. (see CCD) Coating (see Multicoating) ...

A camera that captures an image through the lens but instead of on film, it does it on an an electronic image sensor, a CCD (Charged Coupled Device); then temporarily transferred into a FlashCardâ"¢ for eventual download into a computer.

DIGITAL CAMERA - A camera that takes pictures without film, but instead records the image on an image sensor chip in a format that is readable by a computer.

Making Sense of Camera Sensors The most important part of your digital camera - its brains, heart, and soul - very well maybe its image sensor. It's where all the magic happens and where all the mistakes are made.

and shutter. Light comes through the lens, gets funneled through the aperture that has been selected, and then recorded by the image sensor. The smaller the aperture opening, the less light strikes the sensor.

Even though your camera may pack an image sensor instead of film, taking good pictures still involves understanding apertures, shutter speeds, and metering techniques, as well as a few other issues that film shooters don't face.

A dSLR is really nothing more than a duplication of the traditional manual version, the SLR. It operates on the same principles, with one obvious difference: where a SLR would have film, a dSLR has what is called an image sensor called a CCD or CMOS.
