The reduction of the brightness of the scanning beam to zero when it needs to be moved without updating the picture
The brief suppression of a display signal as the electron beam in a raster-scan display is moved into position to display a new line See also horizontal blanking interval and vertical blanking interval
An early step in preparing flat-rolled steel for use by an end user A blank is a section of sheet that has the same outer dimensions as a specified part (such as a car door or hood) but that has not yet been stamped Steel processors may offer blanking for their customers to reduce their labor and transportation costs; excess steel can be trimmed prior to shipment
The brief period in the television scanning process when the electron beam returns from the right to left or from the bottom to top of the screen, rendering the video signal invisible It is during the blanking interval that closed-captioning and teletext occurs
The process of making a channel, or device non-effective for a certain interval Used for retrace sweeps on CRTs or to mask unwanted signals such as blanking ones own radar from the onboard RWR
1 A video signal level below which no light is emitted from a TV screen (the level at which the screen is blanked) 2 That portion of the time that a video signal is transmitted when it is at or below the blanking level These time portions can be divided into horizontal and vertical blanking levels
replacement of any seedling trees that have died and left blanks in a regular planting pattern
The technique of turning the laser beam on and off with precise control (as opposed to chopping) For scanned graphics, blanking allows images to have disconnected sections where the beam is hidden Blanking can be digital (on/off) or analogue (continuous intensity control) The same techniques used for blanking control can be used to control intensity of red, green and blue beams, for colour mixing [See Also: Acousto-optic modulator; Scanner blanking and colour]
