Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0022] exist figure 1 , figure 2 In the shown embodiment, the hardware organization of this mobile phone ranging system is as follows figure 1 As shown, it includes a camera lens 1 , a CCD 2 , a CCD displacement driver 4 , an image analysis module 3 , and a calculation module 5 . The operating mechanism of the mobile phone ranging system is as follows: figure 2 shown, including the following steps:

[0023] Turn on the camera lens S100: make the object captured by the camera lens be imaged by the CCD and displayed on the screen; in this step, an image zooming step that can be selectively operated by the user can also be included; so that the distant objects that are crowded together It can be spread out during the zoom-in process to facilitate the accurate selection of the desired main focus point.

[0024] Determine the main focus point S110: Select the ma...

Abstract

The invention provides a mobile phone ranging system, and belongs to the field of mobile phone system processing. The mobile phone ranging system comnprises a camera lens, a charge coupled device (CCD), a CCD displacement driver, an image analysis module and a calculation module. The operating mechanism of the system comprises the following steps of: firstly, starting the camera lens; secondly, determining a main focusing point; thirdly, focusing automatically and outputting an image distance; and finally, calculating the distance of an object by using the calculation module according to the image distance and the focal distance of the lens. By using the mobile phone ranging system, the automatic ranging function can be realized by utilizing the conventional mobile phone device without adding hardware cost.

Description

[0001] technical field [0002] The invention relates to the field of electronic systems, in particular to the field of mobile phone system processing. [0003] Background technique [0004] In daily life, it is often necessary to judge the distance between objects and oneself. In general, visual inspection is used. However, the accuracy of visual measurement is very low, and it cannot meet people's needs in many cases; therefore, it is necessary to use optical measuring instruments to assist, for example, a common optical rangefinder can be used. However, this kind of rangefinder belongs to special equipment for engineering surveying and mapping, and it is impossible to carry it at any time in daily life. Therefore, the needs of people's daily life cannot be met. [0005] For this reason, some current daily communication devices such as mobile phones already have a ranging function. There are roughly two main principles: one, the front end of the mobile phone is equipped...
