Problems solved by technology

However, this solution can also be greatly affected by the environment. For example, if the environment is relatively humid, since water vapor will absorb infrared rays, the infrared reflection will be weak and affect the working effect.

Abstract

The invention provides a zooming displayer as well as an electronic device comprising the same and a zoom displaying method. The zooming displayer comprises a display unit, an acquisition unit, a processing unit and a control unit, wherein the display unit is used for displaying information; the acquisition unit respectively acquires the reference positions and size parameters of a plurality of illumination areas on the display unit; the processing unit determines zooming reference points and zooming times according to the reference positions and dimension parameters of two illumination areas in the plurality of illumination areas; and the control unit controls the display unit to implement zooming display on information according to the determined zooming reference points and the determined zooming times. The zooming display can be realized through a non-contact way, and the zooming areas and the zooming times are calculated through the simpler geometrical and optical principles, so that the cost is lower, the environment influence is less, and the operation of a user is simple and convenient.

Description

technical field [0001] The present application relates to a zoom display device, an electronic device including the zoom display device, and a zoom display method. Background technique [0002] In an electronic device capable of displaying information such as images and texts on a screen, it may be allowed to zoom in or zoom out a specific area of ​​displayed information by a specific factor according to a user's instruction. At present, there are mainly two ways to recognize the user's instruction to zoom in on the information displayed on the screen, namely, contact and non-contact. [0003] In the touch-type zooming operation, the touch-sensitive components set in the screen can generally be used to detect operations such as touch pen or finger on the screen panel, such as clicking or sliding, and then the controller calculates and detects the click or touch according to a predetermined algorithm. Sliding the corresponding enlarged / reduced information area and the magnif...
