Problems solved by technology

Although this processing method does not distort the original video or lose any part of the original image, it affects the visual effect of viewing
Moreover, due to the long-term display of black borders on both sides of the screen, the working state of the entire display screen is uneven, and it is easy to accelerate the aging of the display screen
[0005] like figure 2 As shown, the 4:3 image frame is stretched horizo

Embodiment Construction

[0043] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0044] Such as Figure 4 Shown is the main method flow of the display method in the embodiment of the present invention, including:

[0045] Step S401: Receive an image frame whose aspect ratio is a first ratio.

[0046] Step S402: Determine the display portion of the image frame according to a preset height that is less than the height of the image frame and greater than or equal to the height of the safety frame.

[0047] Step S403: Enlarging the display part proportionally until the height of the display part is equal to the display height of a widescreen display with an aspect ratio of a second ratio, wherein the second rat...

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...
