A raster interrupt (also called a horizontal blank interrupt) is an interrupt signal in a legacy computer system which is used for display timing. It is usually, though not always, generated by a system's graphics chip as the scan lines of a frame are being readied to send to the monitor for display.
In a CRT, the vertical scan rate is the number of times per second that the electron beam returns to the upper left corner of the screen to begin drawing a new frame. [3] It is controlled by the vertical blanking signal generated by the video controller, and is partially limited by the monitor's maximum horizontal scan rate.
Motion blur, refers to the reduction in clarity when people track moving objects on a display.This is the result of the display not showing the frame for an infinitesimally short amount of time: your eyes are "tracking" an object that is in fact stationary, resulting in it looking smeared/blurry.
When computer graphics appear on a standard television set, the screen is either treated as if it were half the resolution of what it actually is (or even lower), or rendered at full resolution and then subjected to a low-pass filter in the vertical direction (e.g. a "motion blur" type with a 1-pixel distance, which blends each line 50% with ...
This part of the line display process is the Horizontal Blank. [1] [2] In detail, the Horizontal blanking interval consists of: front porch – blank while still moving right, past the end of the scanline, sync pulse – blank while rapidly moving left; in terms of amplitude, "blacker than black".
When a row line is selected, all of the column lines are connected to a row of pixels and voltages corresponding to the picture information are driven onto all of the column lines. The row line is then deactivated and the next row line is selected. All of the row lines are selected in sequence during a refresh operation. Active-matrix addressed ...
