Abstract

The invention discloses a display method and a display device. The method includes the steps: receiving an image frame with the length-width ratio as a first ratio; determining a display portion of the image frame according to preset height smaller than height of the image frame and larger or equal to height of a safe frame; and amplifying the display portion in equal proportion to the height, equal to display height of widescreen display with the length-width ratio as a second ration, of the display portion, wherein the second ratio is higher than the first ratio. By the method and the device, when the image frame in the first ratio is displayed according to widescreen specifications, pictures within a safe frame range cannot be lost, and distortion of the pictures is avoided.

Description

technical field

[0001] The present invention relates to the field of video processing, and more particularly, to a display method and device. Background technique

[0002] At present, mainstream display devices such as picture tubes, plasmas, liquid crystals, projections, etc. increasingly use widescreen displays for display. Among them, the main display specifications of widescreen monitors are 16:9 or 16:10 (display aspect ratio). However, the signal sent by the TV station and the mainstream specification of DVD are still 4:3. Therefore, when using a widescreen display specification to display a TV signal, it is necessary to process the 4:3 video signal to adapt to the widescreen display.

[0003] Usually, a widescreen monitor will perform the following processing on the video signal of the first ratio:

[0004] Such as figure 1 As shown, the 4:3 image frame is displayed in the center of the widescreen monitor, and black bars are added on both sides to fill the display...
