Problems solved by technology

In the positioning and monitoring of vehicles in traffic, when a detailed understanding and operation of the selected area is required, the limited display screen of the image will make it impossible to immediately and clearly view the various locations or detailed name information of the area
[0003] In general, the corresponding zoom-in function will be set on the image, but this function is only for the zoom-in of the entire image, and will not zoom in or out for the selected area. Such operations cannot immediately display the zoomed-in or zoomed-out view of the selected area. It is to zoom in or out all the images, and then select the desired area for operation
This mode of operation cannot immediately select the area to be enlarged to zoom in or out, which wastes operation time and increases the complexity of the operation

Embodiment Construction

[0014] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] See figure 1 , Which is a functional block diagram 100 of an image zoom system according to an embodiment of the present invention. The functional module diagram 100 includes a selection module 12, a scanning module 14, a positioning module 18, and a control module 20.

[0016] The selection module 12 is used to select an area M to be operated in an image displayed on a screen.

[0017] The scanning module 14 includes a recording sub-module 142, a comparison sub-module 144 and a storage sub-module 146. The recording sub-module 142 stores the abscissa value and the ordinate value of each pixel of the region M to be operated. The comparison sub-module 141 compares the abscissa value and the ordinate value of each pixel to obtain a first pixel A at the leftmost end and a second pixel at the right end of the selected area M from left to rig...

Abstract

The invention relates to an image scaling system applied to amplifying / reducing an image displayed on a screen. The system comprises a selection module used for selecting an area to be operated, a scanning module used for determining the minimum and maximum pixel dots of the abscissa and ordinate value of the area to be operated respectively along the axis of the image, a positioning module used for calculating the coordinate value of the central point of the area selected according to the coordinate value and a control module used for taking the central point obtained by the calculation of the positioning module as a center to amplify / reduce the area to be operated. The invention also provides a method of image scaling. The image scaling system and the method of the invention reduce the operating time, improve operation efficiency and meanwhile cause the operation faster and more convenient.

Description

Technical field [0001] The invention relates to an image zooming system and method, in particular to an image zooming system and method used in a GPS system. Background technique [0002] At present, the popularization of network technology enables images to be widely used in various fields such as the Internet, transportation, navigation, tourism, multimedia, and communications. Images provide corresponding maps and information for different users according to their needs. The images on portable devices such as mobile phones and personal digital assistants show broad prospects due to their convenient portability, the real-time positioning and navigation functions of the Global Positioning System (GPS), and wireless communication network functions. In the process of use, it is necessary to operate and control the image. In the positioning and monitoring of vehicles in traffic, when a detailed understanding and operation of the selected area is required, the limited image display ...
