Embodiment

[0016] In this example, a traditional 4:3 image is displayed on a 16:9 TV screen as an example. The processing method is divided into two major steps: non-linear zooming processing in the horizontal direction of the image and cutting processing in the vertical direction of the image. For the nonlinear zoom processing in the horizontal direction of the image, it includes the following steps (1) Divide the input image into two symmetrical parts, because even if it is nonlinear zooming, we must ensure that the left and right parts are completely symmetrical, otherwise there will be a lot of problems. Strange visual effects affect users' viewing, (the following processing steps must also follow the principle of symmetry, so I won't repeat them here). (2) Divide the left and right parts into three areas W0, W1, and W2. In order to ensure full-screen display, it is necessary to ensure that the sum of the pixel points in the row direction of these three areas = the physical point numb...

Abstract

The invention relates to a method for displaying traditional images on a wide screen for solving the problems of image deformation and easy ageing in the prior art. The method for displaying traditional images on a wide screen comprises the following steps: a. dividing an input image into two eudipleural parts; b. dividing each divided part into M areas again, and the M is greater than or equal to 2 and is a positive integral; c. scaling the linear proportion of N areas in a left half part and a right half part near an image center in a horizontal direction, and the N is greater than or equal to 2 and is an even number; d, scaling other areas in different proportions according to user requirements in the horizontal direction; e. retaining the unchanged effect of the horizontal direction, and after the image is cut in a definite proportion in a vertical direction, linearly stretching the image with the residual proportion to the height of a screen to display. The method for displaying traditional images on the wide screen can improve the visual effect, avoid accelerated screen aging and is especially suitable for displaying traditional signals on a wide screen.

Description

technical field [0001] The invention relates to television technology, in particular to a method for displaying traditional images on a wide-screen television. Background technique [0002] With the rapid development of multimedia and terminal display technologies, display terminals such as wide-screen televisions are becoming more and more widespread, for example, 16:9, 15:9, and 16:9 are currently popular wide-screen. To display traditional images (referring to 4:3 image signals) on these wide screens, the linear processing method is widely used in the prior art, that is, the full screen ratio is used to enlarge and stretch the screen. When the screen is filled, the image has been distorted and deformed, which affects the user's Visual effects. Therefore, in order to maintain the shape of the original image, some users do not perform stretching processing, so the image can only display a part of the screen (such as the middle area), which is a waste of widescreen display ...
