Blink detection-based smart handset photographing system and method

Abstract

The present invention discloses a blink detection-based smart handset photographing system and a method thereof, and mainly solves the problems in the prior art that existing contact type handsets are inconvenient to operate in some cases and the non-contact man-machine interaction manner is hard to be applied to the handset photographing operation. The method comprises the steps of setting the photographing mode of a handset to be a self-timer mode or a common mode; collecting the image sequence of a human face of a photographer by a front-facing camera of the handset, detecting an human eye area, extracting an edge profile, and detecting the occurrence of blinking actions; upon detecting the occurrence of continuous blinking actions, sending a photographing instruction to an instruction sending module; sending the photographing instruction to a photographing module by the instruction sending module; according to the above preset photographing mode of the handset, controlling the camera of the handset to conduct the photographing operation by the photographing module; and indicating the completion of the photographing operation in the form of voices after the photographing process. The invention provides a novel method for controlling the photographing operation based on blinking actions. Based on the method, the convenience of the handset photographing operation is improved. Meanwhile, the photographing function can be realized without the manual operation. Therefore, both the self-timer function of the photographer and the photographing function for other people by the photographer are realized.

Description

technical field [0001] The invention belongs to the technical field of mobile phone photographing, and further relates to the initiation of photographing in smartphone photographing, in particular to a system and method for photographing smartphones based on blink detection. For taking photos with smartphones. Background technique [0002] Nowadays, smart phones are very popular, and taking pictures is a very important and frequently used function in smart phones. The traditional human-computer interaction method of controlling the mobile phone to take pictures is mainly contact type. This method usually starts the camera to complete the shooting when the mobile phone detects a touch screen or a button is pressed, which is inconvenient to operate in some cases. With the rapid development of electronic information technology, there are currently some non-contact human-computer interaction methods, mainly through voice or eye movements to control mobile phones, but there are ...

Problems solved by technology

The disadvantage of this method is that the infrared image of the eyeball is required, so an infrared camera is required to acquire the image, and the final design of the head-mounted device is complicated and difficult to implement on a mobile phone

The disadvantage of this method is that it is necessary to locate the pupil of the human eye and judge the line of sight, and the implementation method is cumbersome and complicated.

The system of this patent is a human-computer interaction system based on line-of-sight judgment, which mainly includes the acquisition of frame images, human eye area detection, pupil center positioning, system calibration, line-of-sight tracking, and control command transmission. In the human eye, the pupil center is positioned, and the focus judgment is realized stably on the electronic device through the camera, and the control command is issued by blinking or closing the eyes. The disadvantage of this system is that the pupil center needs to be positioned, and the system Calibration and eye-tracking, the implementation method is complicated, it is difficult to apply to the realization of the mobile phone shooting system

[0005] The main disadvantage of the above two methods is that the blink detection equipment is complicated, and the infrared image of the human eye is required, or the pupil of the human eye needs to be positioned to judge the line of sight. Realize
