Image enlarging and displaying method and system for mobile terminal

Abstract

The invention discloses an image enlarging and displaying method and system for a mobile terminal. An image is divided into an array comprising M*N rectangles by an image dividing module, when a touch detection module detects that two touch points exist on the image, the rectangles where the two touch points are located are acquired, and a displaying and enlarging module enlarges and displays a rectangular array among rows and columns of the rectangles where the two touch points are located. According to the method and the system, rectangular division and numbering are performed on the image, when a touch screen detects two touch points, the rectangular array among the rows and the columns of the two touch points is enlarged and displayed, the operation that two fingers slide oppositely on the touch screen in the prior art is not required, and the operation difficulty that sliding operations of the two fingers cannot be consistent every time is avoided. The image enlarging operation is more convenient, the image is enlarged through fuzzy operation, and meanwhile, content of the image in the range of the rows and the columns of the two touch points can be enlarged through two touches on the touch screen, so that operation precision is greatly improved.

Description

technical field [0001] The present invention relates to general image data processing, and in particular to a method and system for enlarging and displaying pictures of mobile terminals. Background technique [0002] At present, the pixels of mobile terminal cameras are getting higher and higher, making the photos taken bigger and bigger. Considering portability, the screen of mobile terminals is often no more than six inches, and these large photos may not be visible on the screen. Clear some details, need to zoom in and watch. In the prior art, zooming in a photo on a mobile terminal is often performed by sliding two fingers in reverse on the touch screen, but this method of zooming in is difficult to ensure the accuracy of zooming in, and because each two-finger sliding operation cannot achieve Consistent, it is often difficult to achieve the purpose of zooming in on the same area twice. [0003] Therefore, the prior art still needs to be improved and developed. Conte...
