Sensor Type Designation
Sensors are often referred to with a "type" designation using imperial fractions such as 1/1.8" or 2/3" which are larger than the actual sensor diameters.

Cleaning Camera Sensors
I've never, ever touched a sensor! See cleaning camera sensors.
I spent $5 on a blower bulb (not brush) and it's all I've ever needed these past 5 years to keep all my cameras clean.
Sensor Stamp or Pen. These make full contact with the sensor, but aren't dragged across the sensor surface, so they are less likely to cause a scratch.
The Sensor Cleaning Question "After a vacation trip, I noticed that my images (made with an EOS 10D) have a lot of dust spots. I tried to clean the sensor with a puff of air from a blower bulb as recommended in the owner's manual.

Sensor Size
Image sensors come in a variety of sizes with the smallest ones used in point and shoot cameras and the largest in professional SLRs. Consumer SLRs often use sensors having the same size as a frame of APS film.
Sensors get "grainy" also at higher speed ISO's, but it is now called "noise". Also, "grainy" and "noise" have different textures.
CCD sensors, as mentioned above, create high-quality, low-noise images. CMOS sensors, traditionally, are more susceptible to noise.
The sensor size in a digital camera impacts lens selection and noise reduction. Larger sensors are less susceptible to digital noise -- typically colored pixels that appear in the darkest portions of an image.
The sensor construction on the Canon EOS D60
Technical note: The dust isn't actually on the sensor surface. It's on the surface of a filter which is in front of the actual sensor itself. This is why dust shows up more at smaller apertures.
CMOS sensors (Complementary Metal-Oxide Semiconductor) are easier and cheaper to produce because of a more conventional manufacturing process. They also consume less power than CCDs.
Because CCD sensors register optical images in black and white, filters are required to produce colours. These filters contain red, green or blue colours and are placed over every photocell.
The Foveon X3 sensor is difficult to classify by megapixel (MP) count compared to mosaic sensor cameras, in which the location count and photosensor count are the same.

The film in a film camera performs the function of two items in digital camera - the image sensor and the digital memory card.
Additionally, the sensor and photosites must be able to record or understand colors which is accomplished by a filter applied to the surface of the sensor, and which is capable of distinguishing a set range of colors within the recorded image.
As shown in the illustration (Fig. 2) of the image sensor cross-section, the sensor surface is equipped with microlenses, with a small gap between them.

Looks like you've done it again. For a while there, you thought you had it all taken care of. I mean, you just cleaned your digital camera sensor. How could it possibly have gotten dirty again?

Sensor Size
Quite apart from the pixel count, the actual dimensions of the sensor is very important. Not all sensors are the same shape and size, and the pixel count is no indication of the actual, real-world dimensions.
Sensor Size
The size of the digital sensor element (which is equivalent to the size of the negative for film cameras) is pretty small in all consumer digicams - typically around the size of a fingernail (and a small fingernail at that!).
Sensor Dust — A Different Opinion for Portrait and Wedding Photographers
Certainly the best way to avoid sensor dust is to limit the number of times one changes lenses, whether in studio or out on location.

Sensor simulator is a java standalone application that simulates sensor data and transmits them to the Android emulator.
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.
Sensor: CMOS sensors consume less power and dissipate heat better than CCDs, making them the ideal starting point for eliminating noise.

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.
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.
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.

Sensor Noise / Grain (or, as I keep calling it, "grainyness")
Just as some film pictures sometimes look "grainy", some digital pictures look "noisy".
Sensor: Is the sensor free of dust? I usually try to check this the night before a shooting session.
Sensor dust, in particular, is a near-negligible issue-with ten minutes, a clean workspace, a blower bulb and a set of lenspens, you can have it clean. There's no reason to not switch lenses unless you're in particularly hostile conditions (e.g.
Sensors when the camera is turned vertically or horizontally (some also do when the swivel LCD is turned) and "flips" the image accordingly. The writer considers this very useful when taking some "product" photographs.

(3) Sensor dust! Every speck of dust on your image sensor becomes more visible at smaller apertures, resulting in an overall hazier image and a long Photoshop session afterwards with the clone tool.
