Many motion blur factors have existed for a long time in film and video (e.g. slow camera shutter speed). The emergence of digital video, and HDTV display technologies, introduced many additional factors that now contribute to motion blur. The following factors are generally the primary or secondary causes of perceived motion blur in video.
There are additional aspects to LCD color and color management, such as white point and gamma correction, which describe what color white is and how the other colors are displayed relative to white. Brightness and contrast ratio: Contrast ratio is the ratio of the brightness of a full-on pixel to a full-off pixel.
In optics, chromatic aberration (CA), also called chromatic distortion, color aberration, color fringing, or purple fringing, is a failure of a lens to focus all colors to the same point. [ 1 ] [ 2 ] It is caused by dispersion : the refractive index of the lens elements varies with the wavelength of light .
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().

Lower-end digital cameras, including many mobile phone cameras, commonly use gaussian blurring [citation needed] to obscure image noise caused by higher ISO light sensitivities. Gaussian blur is automatically applied as part of the image post-processing of the photo by the camera software, leading to an irreversible loss of detail.

The original HP digital camera was an Intel Miniature Card-based model simply called the Photosmart.It was a VGA-resolution camera with a simple LCD.The company later broadened its line with a number of series of cameras, all using the Photosmart name.
The ISO setting on a digital camera is the first (and sometimes only) user adjustable gain setting in the signal processing chain. It determines the amount of gain applied to the voltage output from the image sensor and has a direct effect on read noise. All signal processing units within a digital camera system have a noise floor.
