Image resizing display method, display system, display device and terminal

Abstract

The invention provides an image adjusting proportion display method. The method comprises steps that a local brightness value of each local image and the integral brightness value of an image are acquired; a first display proportion value corresponding to each local image is determined according to the local brightness values and the integral brightness value; each local image is displayed according to the corresponding first display proportion value to accomplish an image adjusting proportion display process. According to the method, each local image is amplified differently according to difference of the local average brightness values of the local images, the adaptive amplification effect is realized, moreover, the local average brightness value difference of the local images is quite small, distortion of a to-be-adjusted-in-proportion image does not occur when the local images are amplified. The invention further provides an image adjusting proportion display system, an image adjusting proportion display device and a terminal.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image scaling display method, an image scaling display system, a display device and a terminal. Background technique [0002] In view of the increasingly perfect camera functions of terminal devices and the continuous improvement of camera effects, terminal users rely more on terminal devices to record various image information in daily life. However, due to the limited size of display devices such as mobile phones and tablets The display screen is limited, and users usually use the method of zooming in on the image to check the details of the image. [0003] In related technologies, the modification of the display effect of the image by the terminal includes parameters such as brightness, color, contrast, and grayscale. The display method has several disadvantages: [0004] (1) When the user uses the macro mode to collect images, the adjustable depth of fie...

AI Technical Summary

Problems solved by technology

[0004] (1) When the user uses the macro mode to collect images, the adjustable depth of field of the image is very small. When zooming in on the focused object, the distant object is also enlarged in the same proportion. Therefore, when the details of the focused object are clearly seen, the details of the distant object are reversed. become blurred;

[0005] (2) When the user takes a picture with a relatively large contrast between light and dark, for example, an object under the sun and an object under the shade of a tree are photographed at once, and if the object under the shade of the tree is displayed at the same magnification as the object under the sun, the shade of the tree The objects below will be displayed too rough, and the details are not clear;

[0006] (3) When the image taken by the user in the night scene is zoomed in for viewing, other objects except the focused object will also be displayed too rough, and the details are not clear
