A typical video tearing artifact (simulated image) Screen tearing [1] is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. [2] The artifact occurs when the video feed to the device is not synchronized with the display's refresh rate.
The way paper texture effects become relatively more pronounced as negative size decreases can be demonstrated with a digital camera by photographing a sheet of paper lit from behind, first at a distance where the sheet just overfills the field of view, and then at a closer distance where the field of view is perhaps one third as wide.
Illustration of the effect of JPEG compression on a slightly noisy image with a mixture of text and whitespace. Text is a screen capture from a Wikipedia conversation with noise added (intensity 10 in Paint.NET). One frame of the animation was saved as a JPEG (quality 90) and reloaded.
Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set.
The drawing on the upper right shows a moiré pattern. The lines could represent fibers in moiré silk, or lines drawn on paper or on a computer screen. The nonlinear interaction of the optical patterns of lines creates a real and visible pattern of roughly parallel dark and light bands, the moiré pattern, superimposed on the lines. [4]
The 720p format produces 59.94/50 or 29.97/25 1280×720p images, not squeezed, so that no expansion or squeezing of the image is necessary. This confusion was industry-wide in the early days of digital video software, with much software being written incorrectly, the developers believing that only 29.97 images were expected each second, which ...
