detailed description

Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

1-2, the control method according to the embodiment of the present invention can be used to control the electronic device 1000. The electronic device 1000 includes an imaging device 200, an acceleration sensor 300 and a display 400. The control method may include the following steps:

S1, processing the output of the acceleration sensor 300 during the shooting period of the imaging device 200 to obtain the acceleration information of the electronic device 1000; and

S3, controlling the display 400 to display prompt information corresponding to the acceleration information.

The control method in the embodiment of the present invention may be applied to the control device 100 in the embodiment of the present invention, and the control device 100 may include a processing module 110 and a control module 130 . The processing module 110 can be used to implement step S1, and the control module 130 can be used to implement step S3. That is to say, the processing module 110 can be used to process the output of the acceleration sensor 300 during shooting by the imaging device 200 to obtain the acceleration information of the electronic device 1000; the control module 130 can be used to control the display 400 to display prompt information corresponding to the acceleration information.

The control device 100 of the embodiment of the present invention can be applied to the electronic device 1000 of the embodiment of the present invention. Wherein, the control device 100 can be integrated inside the electronic device 1000 , or can be used as an external device outside the electronic device 1000 to establish a connection with the electronic device 1000 . The integration of the control device 100 inside the electronic device 1000 helps to enrich the functions of the electronic device 1000. The control device 100 is used as an external device, such as a plug-and-play chip similar to a USB flash drive, which is more flexible to use and can be used with different electronic devices 1000 use.

In the embodiment of the present invention, the acceleration sensor 300 can be used to sense the acceleration information of the electronic device 1000. Generally speaking, if the electronic device 1000 shakes or moves violently, a relatively large acceleration will be generated and sensed by the acceleration sensor 300. It is measured that if the electronic device 1000 is in a relatively static state or in a state of uniform linear motion, no acceleration will be generated. When the electronic device 1000 shakes or moves in an unstable state, that is, when the acceleration is relatively high, it is easy to take blurred pictures.

Please refer to FIG. 3 , in the control method or the control device 100 according to the embodiment of the present invention, during the shooting period of the user, for example, a user who uses a mobile phone to take pictures, after opening the camera application of the mobile phone, the acceleration sensor 300 will sense the acceleration information of the mobile phone, And the prompt information corresponding to the acceleration information is displayed by the display 400, for example, the magnitude, direction, etc. of the current acceleration are displayed, or the numerical value of the acceleration is not displayed, but the arrow line 410 or color is used to represent the magnitude of the acceleration or in a more vivid way such as color. direction.

For example, in some implementations, the magnitude and direction of the acceleration of the electronic device 1000 is represented by an arrow line 410 extending from a central point of the screen, the direction of the arrow line 410 represents the direction opposite to the direction of the acceleration, and the arrow line The length of 410 represents the magnitude of the acceleration. When the acceleration is 0 or close to 0, the arrow line 410 is not displayed.

In this way, the user can intuitively see the current acceleration of the electronic device 1000, that is, the motion state of the electronic device 1000, so that the user can choose an appropriate time to take a photo, for example, press the shooting button 500 with a finger to take a photo when the acceleration tends to zero. Take clearer photos. In addition, the user can exert force on the electronic device 1000 in a direction opposite to the acceleration according to the magnitude and direction of the acceleration to counteract the movement tendency of the electronic device 1000 . In this way, the electronic device 1000 can be in a more stable state, so as to take clearer pictures.

In fact, in daily life, for example, when taking pictures on a bumpy car, people will involuntarily exert force to counteract the external force and keep it stable, but people's ability to perceive the state of motion is limited, so the balance achieved by this effort is limited. By adopting the control method or the control device 100 of the embodiment of the present invention, the acceleration information of the electronic device 1000 can be displayed to the user, so that the effect of getting twice the result with half the effort can be achieved when the user tries to balance the electronic device 1000 .

In some embodiments, the imaging device 200 may be a mobile phone or a tablet computer. Mobile phones or tablet computers are also commonly used shooting devices in people's daily life.

Referring to FIGS. 4-5 , in some embodiments, the acceleration information may include an acceleration component of the electronic device 1000 in a direction perpendicular to the optical axis 250 of the imaging device 200 .

The optical axis 250 of the imaging device 200 refers to the shooting direction of the imaging device 200 . For example, the electronic device 1000 in some embodiments is a mobile phone, correspondingly, the imaging device 200 is a mobile phone camera, and the optical axis 250 is a line passing through the center of the mobile phone camera lens 210 . The external light enters the lens 210 along the optical axis 250 and irradiates the image sensor 230 behind the lens 210 to form an image.

The direction perpendicular to the optical axis 250 is any direction on the plane 270 perpendicular to the optical axis 250 . For example, the optical axis 250 in FIG. 5 is parallel to the x-axis of the coordinate system, and the plane formed by the y-axis and the z-axis of the coordinate system is a plane 270 perpendicular to the optical axis 250 . When shooting, if there is shaking along the shooting direction (ie, the direction of the optical axis 250), it generally has little effect on imaging, because the movement along the shooting direction will cause the captured image to be enlarged or reduced, but will not cause image translation. The movement distance of the electronic device 1000 in the shooting direction caused by shaking is generally negligible compared to the object distance (that is, the distance from the scene to the lens 210 of the imaging device 200 ), especially when shooting distant scenes. However, shaking on the plane 270 perpendicular to the optical axis 250, whether moving up and down or moving left and right, will cause obvious translation of the captured image.

Generally speaking, displaying 2D information on the display 400 is more intuitive and clear than displaying 3D information. Moreover, 3D acceleration information is not conducive to quick understanding and quick response of users.

Therefore, in step S1 or in the processing module 110 , the output of the acceleration sensor 300 is processed to obtain only the acceleration component in the direction perpendicular to the optical axis 250 . In this way, the acceleration information can be displayed more intuitively, helping the user to react quickly when holding the electronic device 1000 .

Referring to Figures 6-7, in this embodiment, the control method may further include the following steps:

S2, judging whether the acceleration component is less than a predetermined value, if the acceleration component is less than the predetermined value, return to step S1, and if the acceleration component is greater than or equal to the predetermined value, enter step S3.

The step S2 can be implemented by the judging module 120 of the control device 100 in some embodiments. That is, the judging module 120 is used to judge whether the acceleration component is smaller than a predetermined value. The processing module 110 processes the output of the acceleration sensor 300 during shooting by the imaging device 200 to obtain acceleration information of the electronic device 1000 when the acceleration component is less than a predetermined value. The control module 130 controls the display 400 to display prompt information corresponding to the acceleration information when the acceleration is greater than or equal to a predetermined value. Step S2 may be after step S1, and if it is determined that the acceleration component is less than a predetermined value, then return to step S1 to continue processing the output of the acceleration sensor 300 .

That is to say, if the acceleration component on the plane 270 perpendicular to the optical axis 250 is too small, such as less than a predetermined value, it means that the vibration of the electronic device 1000 on the plane perpendicular to the optical axis 250 is negligible. The display 400 may not be controlled to display the acceleration information, or the magnitude of the acceleration may be displayed as zero, so as to avoid causing "overcorrection" by the user. Because the user's manual adjustment accuracy is limited, if very small accelerations are displayed, the user will use too much force on the electronic device 1000 if he does not pay attention after seeing it. The result of over-correction is greater acceleration, which is not conducive to Take clear photos.

If the acceleration component on the plane 270 perpendicular to the optical axis 250 is greater than or equal to a predetermined value, it indicates that the shaking has reached a considerable degree. At this time, the acceleration needs to be displayed to help the user manually adjust the electronic device 1000 .

The predetermined value may be the preset value of the system of the control device 100, or a set value input by the user externally. Conditions and requirements selection. Different files correspond to different preset values.

In this embodiment, after judging and filtering the magnitude of the acceleration component, the display 400 can only display the acceleration when the shaking reaches a certain degree of severity, so as to adapt to the adjustment accuracy of the human body, thereby giving the user a better experience.

Please refer to FIG. 3 together. In this embodiment, the prompt information may include an arrow line 410 opposite to the direction of the acceleration. For example, when the direction of the acceleration is right, an arrow line 410 pointing to the left is displayed, so that the user can follow the prompt of the arrow line 410 to make an appropriate force to the left to counteract the movement tendency of the electronic device 1000 to the right.

In this embodiment, the length of the arrow line 410 may be positively correlated with the magnitude of the acceleration. That is to say, the greater the acceleration, the longer the length of the arrow line 410; conversely, the smaller the acceleration, the shorter the length of the arrow line 410.

In this way, it is helpful for the user to have a rough judgment on the vibration amplitude while judging the direction, so as to better control the strength of manual adjustment.

The positive correlation can be a proportional relationship or a non-linear positive correlation, for example, the length of the arrow line 410 is the logarithm of the acceleration.

Please refer to FIG. 3 , the arrow line 410 can extend outward from the central point. If the acceleration is greater, the extension will be longer, and if the acceleration is smaller, then it will be shorter. When the user sees no arrow line 410 or the arrow line 410 is short, he can press the shooting button 500 to take a picture.

Please refer to FIG. 2 , the present invention also provides an electronic device 1000 , which may include an imaging device 200 , an acceleration sensor 300 and the control device 100 in the above embodiments.
