[0038]When it is detected that the screen of the mobile electronic device is touched, the touch screen focus is triggered and the focus obtained by the touch screen focus is saved. Simultaneously detect the degree of shaking of the mobile electronic device, if the degree of shaking is greater than or equal to the first shaking threshold, and if focusing is currently taking place, cancel the current focusing action, then determine that the mobile electronic device is shaken normally, and detect that the degree of shaking is low The first-level focus is triggered when the shaking level is greater than or equal to the second shaking threshold, and it is determined that the mobile electronic device is shaken violently, and the second-level focus is triggered when the detected shaking level is lower than the stillness threshold.

[0039] In this embodiment, the first-level focus is refocusing with the focus obtained by the touch screen as the first-level focus; the second-level focu...

[0041] While the user is focusing through the manual focus function of the mobile electronic device, the degree of shaking of the mobile electronic device is detected. If the degree of shaking is greater than or equal to the first shaking threshold, it is determined that the mobile electronic device is shaken normally. At the same time, if focusing is currently occurring, then Cancel the current focusing action, and trigger the first-level focus when the degree of shaking is detected to be lower than the static threshold, if the degree of shaking is greater than or equal to the second shaking threshold, it is judged that the mobile electronic device is violently shaken, and when the degree of shaking is detected is lower than Secondary focusing is triggered at rest threshold.

[0042] In this embodiment, the primary focus is to perform spot metering with the focus obtained by manual focusing as the primary focus; the secondary focus is to clear the focus obtained by manual focu...

Abstract

The invention discloses a shaking detection-based continuous focusing method and system for mobile electronic equipment, aiming to solve the problem that mobile electronic equipment is light in weight and prone to shaking during focusing, resulting in focusing failure, and proposes a shaking detection-based focusing method. The technical points of the present invention include: detecting the degree of shaking of the mobile electronic device, and if the degree of shaking is greater than or equal to the first shaking threshold, it is judged that the mobile electronic device is shaken normally, and when the degree of shaking is detected to be lower than the static threshold, a first-level focus is triggered, If the shaking degree is greater than or equal to the second shaking threshold, it is judged that the mobile electronic device is shaken violently, and triggers the secondary focus when it is detected that the shaking degree is lower than the static threshold; the first shaking threshold is smaller than the second shaking threshold, the static threshold less than the first shaking threshold.

Description

technical field [0001] The invention relates to the technical field of photographing and focusing of mobile electronic equipment. Background technique [0002] Mobile electronic devices such as mobile phones and tablets are highly portable and can take pictures in almost any scene. However, due to the small weight of mobile electronic devices, especially mobile phones, it is easy to fail to focus when taking pictures, resulting in a blurred viewfinder interface. . In the current market, focusing methods for mobile electronic devices are nothing more than manual focusing, automatic focusing, and touch screen focusing. [0003] The manual focus means that the user can input focus parameters, and the mobile electronic device focuses according to the values. Auto focus means that the mobile electronic device automatically calculates the clearest point in the shooting picture as the focus. Touch-screen focusing means that the mobile electronic device focuses according to the p...
