The LBCAST (Lateral Buried Charge Accumulator and Sensing Transistor array) developed by Nikon realises a new concept in image sensors.
Image sensors come in a variety of aspect ratios— the ratio of image height to width. The ratio of a square is 1:1 (equal width and height) and that of 35mm film is 1.5:1 (1½ times wider than it is high).
Both CCD (charge-coupled device) and CMOS (complementary metal-oxide semiconductor) image sensors start at the same point -- they have to convert light into electrons.
Image Sensor
A semiconductor circuit inside the camera made of millions of light sensitive elements on which the camera lens forms its image.
Image sensor
An image sensor is a type of transducer (an electronic device that converts one type of energy to another).
Image Sensors
A scanner uses one of two sensor methods: contact image sensor (CIS) or charge-coupled device (CCD). Scanners with CCD employ bright light that lights up the image and rows of pixels capture the image.

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. 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.
Image sensor
The semiconductor chip or Image Sensor is what captures the photographic image. It collects the light of a scene or subject, which it turns into digital data that we see as a photo in the camera or on the computer.

CMOS image sensors are now capable of creating HDR images up to 110dB, for chips up to 2mp, and form factors of 1/5", immediately, for low cost in contrast to extremely costly CCD sensors.
Contact Image Sensor (CIS) - Used in smaller, low-cost scanners, a new type of image sensor that has limitations on resolution.
Clone - To copy pixels from one part of an image to another.
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.

Image sensors have an innate 'native' sensitivity, generally in the ISO 100 to 200 range. When you set a higher ISO speed, amplifiers in the image sensor's circuitry increase the gain before sending the image data to the A/D converter to be digitized.
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 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.
...
An image sensor is a device that converts an optical image to an electric signal. It is used mostly in digital cameras and other imaging devices.
CCD
The image sensor (charge coupled device) inside the camera or scanner which captures the image through the lens.
Crop
To delete part of an image or its border for a more pleasing effect through the elimination of distracting or unwanted details.
A type of image sensor commonly employed in digital cameras and scanners.
Your camera's image sensor contains a limited number of pixels, which is the sensor's overall resolution. The senor uses only some of those pixels to create a digital photo. That is the effective resolution.
Pixels on the image sensor that misread the light.
Noise reduction:
When a slow shutter speed is used (1/30 sec. and lower), the image degrades due to the buildup of electronic signal ("noise").
Go to the Setup menu, select "Clean image sensor" and press the button. All the hard work is then automatic. You can even set the camera to automatically clean the sensor this way at startup or at shutdown. Or both.
Line sensor
Image sensor that is read line for line and of which the CCD is a typical example.
The E-P1's Live MOS image sensor is complemented by Olympus' next-generation TruePic™ V Image Processor, which produces clear and colorful photos using all the pixel information for each image to provide the best digital images possible.
CMOS Complementary Metal-Oxide Semiconductor: one of the two main types of image sensors used in digital cameras. Its basic function is the same as that of a CCD. CMOS sensors are currently found in only a handful of digital cameras.
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.
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 camera could use a fixed half-silvered "pellicle" mirror so light reaches both the viewfinder and the image sensor.
It was the 17th of October when the image sensor was discovered. If you don't already know, the image sensor is like the heart of all digital cameras. Without it, there will be no digital photography.
An image sensor of about 1 square inch requires super excellent optics if the resulting images are going to be made into big prints.
As happens occasionally, technological solutions do not solve the problems that gave rise to their invention, and so it was with the image sensor. CCD was not to have a future in memory storage, but it did lead to an explosion in digital imaging.
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.
RAW - A RAW image file is a variety of image file that contains unprocessed (or minimally processed) data from the image sensor of a digital camera or image scanner, without processing them into a more common image format such as JPEG or TIFF.
Sensors: CCD - Charge Coupled Device: one of the two main types of image sensors used in digital cameras, with CMOS - Complementary Metal-Oxide Semiconductor, being the other.
The image sensor that separates the spectrum of color into red, green and blue for digital processing by the camera. [In digital cameras both Area and Linear CCDs are used. A CCD captures only black-and-white images.
A CCD or Charge-Coupled Device is an analog electronic device that can be used as the image sensor in place of film in an electronic camera or optical devices like microscopes or telescopes.
Digital image anomalies caused by the image sensor, optics or internal image processing of the camera.
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.
When you take a picture you allow an amount of light through the lens, focusing it onto the image sensor. The amount of light you let in is measured in stops.
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.
RAW data (which Nikon call NEF data) is the output from each of the original red, green and blue sensitive pixels of the image sensor, after being read out of the array by the array electronics and passing through an analog to digital converter.
Sensitivity is a measurement of how something (in the case of digital photography, the image sensor) responds to light. The image sensor's sensitivity is a key component is establishing an exposure.
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.
Your eyes are the ultimate image sensors. They have a nonlinear response curve enabling you to see very bright areas in the presence of dark shades. Your camera does not have that capability.
Many digital SLRs use an image sensor that is smaller than 35mm film. If you attach a lens to one of these cameras, its 35mm equivalency will be multiplied by the cropping factor-a manufacturer's specification.
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.
These ratios refer to the size of the image captured on the digital image sensor or film compared to the size of the object in real life.
Large format, medium format, or 35mm, but determined by the actual dimensions of the focal plane or image sensor.
RAW files are raw image data captured by the image sensor before any in-camera processing has been applied.
14 Bit A/D Conversion Analog to Digital conversion is usually the first stage in the process of converting an analog signal coming from the image sensor via multiple channels into digital data for the image processing and storage of image data.
Direct exposure to the sun while it is high in the sky can damage the delicate image sensor found in most digital cameras, the CCD. Fortunately as the sun approaches the sunset its intensity will diminish greatly.
When VR/IS is on, the lens element(s) or image sensor move so that the image stays in place when projected onto the sensor. As a result, camera motion is less likely to affect the sharpness of your photographs.
One problem with digital cameras is that there are always some pixels on the image sensor which are bad. When taking day photos, these defects are not discernible. However, they are pretty obvious in night photos. How do we correct these?
With the exception of a few full-frame sensors (Canon EOS1DSMKII and Kodak SLR/N), D-SLR image sensors are usually a bit smaller than 35mm film, typically 13mm or 19mm along the shorter side as compared to film's 24mm.
