Embodiment Construction

[0022] This embodiment proposes a screen zooming method, which can zoom in or zoom out the display screen according to the size of the area circled by the user's finger. The method is applicable to various portable touch devices, such as mobile phones, portable players, digital cameras, and the like.

[0023] Such as figure 1 As shown, it is a flow chart of the steps of the screen zooming method in a preferred embodiment, including the following steps:

[0024] Step S301, recording the circle-drawing track generated by the user's circle-drawing operation on the touch screen. see figure 2 and image 3 , the circle-drawing tracks 102 and 104 generated by the user's clockwise and counter-clockwise circle-drawing operations are displayed on the touch screen 10 respectively.

[0025] Step S303, detecting the area of ​​the circle surrounded by the circle track. The area can be calculated according to the number of pixels included in the circled area or the number of touch matr...

Abstract

The invention discloses an aspect ratio adjusting method, comprising the following steps: recording circling trail generated by circling operation of a user on a touch screen; detecting the circling area enclosed by the circling trail; calculating the ratio relationship between the circling area and preset area; and adjusting display aspect ratio according to the ratio relationship. When using theaspect scaling method above, a user only need circle by one finger so as to realize enlarging or diminishing for the chosen area according to the ratio relationship, and the operation is simple, convenient and fast. The invention also provides electronic equipment with a touch screen using the method of the invention.

Description

technical field [0001] The invention relates to image zooming technology, in particular to an electronic device with a touch screen and a method for adjusting the screen ratio thereof. Background technique [0002] At present, touch screen technology is becoming more and more popular because of its simple operation, diverse functions and gradually falling prices. The touch screen allows users to zoom in and out of web pages or browse files through two points. For example, Apple's iPhone is achieved through two fingers. Web page zoom in and zoom out or file browsing function. However, for people with handicapped fingers, it is necessary to utilize two fingers simultaneously to realize this function, and it is difficult to move in operation. Contents of the invention [0003] In view of this, it is necessary to provide an electronic device with a touch screen which is easier to adjust the aspect ratio. [0004] It is necessary to provide a method for adjusting the screen r...
