Problems solved by technology

However, since the user cannot accurately determine the position of the center point of the two touch points, it is easy to produce a zoom deviation during the zoom operation, which makes the target zoom area different from the expected effect.

Embodiment Construction

[0037] Such as figure 1 As shown, it is a flow chart of the steps of the image scaling method in a preferred embodiment of the present invention, including the following steps:

[0038] Step S101 , receiving a plurality of control points for image display control input by a user through body gestures.

[0039] The image may be a three-dimensional stereo image, or a two-dimensional planar image. When the image is a three-dimensional image or a holographic image, the plurality of control points are located in a three-dimensional space. Holographic images can be realized with a projection enhancement system consisting of two spectacle lenses and a "table" with two micro-projectors mounted on each spectacle frame. Each projector transmits a stereoscopic 3D perspective image to this retroreflective plane (using the principle of interference and diffraction), and a miniature camera is installed between the projectors to scan the infrared identification mark on the plane. The came...

Abstract

Provided are an image display control method and terminal. The image display control method includes the following steps of receiving a plurality of control points input by a user through postures, wherein the control points are used for controlling image display; detecting the relatively fixed position and the relatively moving position corresponding to the limbs of the user in the postures according to the multiple control points, determining the control point corresponding to the relatively fixed position as a control located point, and determining the control point corresponding to the relatively moving position as a control changing point; carrying out display control over images with the control located point as a center according to the position change information between the control located point and the control changing point. By means of the image display control method and terminal, the user can carry out image display control such as scaling with an expected scaling center only through one-time operation, and the problem that a traditional control center can not be controlled is solved, so that deviation between the images obtained after display control is carried out and an expected result is smaller.

Description

technical field [0001] The present invention relates to image display control technology, in particular to an image display control method and terminal based on multi-touch technology. Background technique [0002] Image display technologies mainly include two-dimensional screen display and three-dimensional stereoscopic display. During the image viewing process, the image is often zoomed and the contrast, image sharpness, and image color saturation are operated. Take the touch screen display as an example: the touch screen is a kind of An inductive liquid crystal display device that receives input signals such as contacts, as a new terminal input device, realizes simple and convenient human-computer intelligent interactive applications. Today, touch screens are widely used in industrial control, intelligent transportation, building monitoring, and PDA fields. It is widely used, and the use on smartphones is more common. [0003] At present, when performing image zooming on...
