Summer Test: Image-Stabilizing Digital CamerasWired Staff
Image noise Digital noise (similar to grain) is side effect of shooting – caused by digital cameras. The presence and amount of noise can increase depending on your shooting conditions: lighting, shutter speed and ISO. Noise appears as unwanted dots, lines and smudges of color within your i...
Cameras are categorized into CCD and CMOS cameras based on their image sensors. CCD sensors are the most common type and provide high-quality images with less noise compared with CMOS sensors. Gimbals are used for motion control and camera stabilization in UAVs [52]. They have three separate ...
In the CCD response-based methods, the image noise is assessed by noise sources, which are introduced by CCD cameras. In [4], according to a pair of studies on the CCD Photon Transfer Curve (PTC) and camera noise characters, a complete equation of different noise sources of image sensor ...
The blue and green channels will usually have the highest and lowest noise, respectively, in digital cameras with Bayer arrays (see "Understanding Digital Sensors"). Also note how the Epson develops patches of color which are much more objectionable than noise caused only by brightness fluctuations...
Sharpens the image. Removing noise reduces image sharpness. Use the sharpening control in the dialog box or use one of the other Photoshop sharpening filters later to restore sharpness. Remove JPEG Artifacts Removes blocky image artifacts and halos caused by saving a image using a low JPEG quality...

ISO and digital noise in the image are closely related. When you increase the ISO above a particular value, the digital noise increases. You can see it in the form of grains in the image. In the ISO chart, you can see that the noise increase with the increase in ISO. The noise level...
PureImage will automatically auto-tune the noise function to different noise type across the image, making the interface much simpler and universal for all digital or film cameras. There are few Advanced Processing presets for better tuning the NR algorithm ...
