Embodiment

[0015] Such as figure 1 As shown, the hardware implementation solution of the present invention includes: an embedded mobile device 1, an infrared emitting tube 2, an infrared sensor 3, an isolation device 4, a shield 6, and the like. Picture 7 or the electronic map data and zoom algorithm program are stored in the Flash of the embedded mobile device, and are automatically loaded into SDRAM to run after the system is turned on. Infrared emitting tube 2 has a good concentration, emits infrared light 5, and after being reflected by the blocking object 6, it is received by the infrared sensor 3. According to the intensity of the received infrared light 5, the infrared sensor 3 and the blocking object are calculated. 6 distances between. The isolating device plays a protective role and is used to isolate components such as the infrared emitting tube 2 and the infrared sensor 3 . The shield 6 is used to reflect the infrared light 5 back to facilitate the infrared sensor 3 to ...

Abstract

The invention provides a method for achieving automatic contraction and expansion of an image and a map by using an infrared distance sensor. According to an infrared range sensor principle, by detecting the intensity of infrared light rays emitted from an infrared emitting tube, the distance between embedded mobile equipment and a blocking object is calculated, the moving direction of the blocking object is judged, and therefore contraction and expansion functions of the map and the image are achieved. According to the method, by means of motions when a human hand carries out downward pressing or upward pulling on the embedded mobile equipment, and the contraction and expansion functions of the image and the map can be conveniently achieved. The method has the advantages of being simple in operation, convenient and the like.

Description

technical field [0001] The invention relates to a method for realizing zooming of pictures and maps, in particular to a method for realizing automatic zooming of pictures and maps in an embedded mobile device by sensing the moving direction of an occluder through an infrared distance sensor. Background technique [0002] The traditional method for realizing image and map zooming is mainly to complete by clicking the mouse in the PC-based application program interface. However, in embedded mobile devices (such as mobile phones, PDAs, etc.), most of them do not configure a mouse due to their small size and portability. Generally, the image and map zoom functions are realized by clicking the zoom in and zoom out buttons on the application program interface. , making the operation inconvenient, and the user experience is not strong. Contents of the invention [0003] Aiming at the shortcomings of the traditional method of zooming pictures and maps in embedded mobile devices, ...
