1 and 2, an embodiment of the photographing device 1 of the present invention includes a hollow body 11, a surface 12, a photographing unit 13, a vibration unit 14, and an electrical connection between the photographing unit 13 and the vibration The processing unit 15 of the unit 14, and the vibration unit 14 and the processing unit 15 are, for example, disposed in the main body 11, but it is not limited thereto. Specifically, the photographing device 1 can be used as, for example, a driving recorder that can be installed on a motorcycle or a helmet, or can also be used as an outdoor sports camera, but it is not limited to this.

In this embodiment, the surface 12 is, for example, a transparent material (such as acrylic or glass) and is formed on the body 11, and the positions of the surface 12 and the photographing unit 13 correspond to each other as shown in FIG. 1, Thereby, the surface 12 allows light outside the photographing device 1 to enter the photographing unit 13 through the surface 12 itself. More specifically, the photographing unit 13 is, for example, implemented as a photographing lens, and the surface 12 is, for example, the outer side of a protective lens of the photographing lens, that is, the photographing unit 13 can face from the inner side of the surface 12 The outside of the surface 12 is photographed. On the other hand, the vibration unit 14 is implemented as a small vibration motor, for example, and the vibration generated by the vibration unit 14 can be transmitted to the surface 12 through the body 11, that is, when the vibration unit 14 vibrates , The surface 12 will vibrate along with the vibrating unit 14.

It is added that in other embodiments, the surface 12 may also be formed on the photographing unit 13. In other words, the surface 12 may also be a part of the photographing unit 13 in other embodiments. The lens surface. In addition, in particular, it should be noted that the appearance of the main body 11 of the photographing device 1 in FIG. 1 is only an example. The focus of FIG. 1 is to assist in explaining the surface 12 and the photographing unit 13 in this embodiment. The position correspondence relationship in is not used to limit the overall appearance of the photographing device 1.

Referring to FIGS. 1 to 3 at the same time, the following exemplarily describes in detail how the photographing apparatus 1 of this embodiment implements a photographing method.

First, in step S1, the processing unit 15 controls the photographing unit 13 to shoot to generate a dynamic image, for example, according to a user's operation. In this embodiment, the dynamic image is a movie generated by the real-time recording performed by the photographing unit 13, and the dynamic image has a key image area covering the center of the dynamic image. For example, the key image area can be, for example, a circular area located in the center of the dynamic image, or it can be, for example, a square area located in the center after the dynamic image is divided into nine square grids of equal area. In short, the key image The region can be implemented as long as it is a part of the dynamic image that covers its center position, and it is not limited to the above-mentioned examples. In addition, it is supplemented that in the subsequent steps, the processing unit 15 controls the photographing unit 13 to continuously shoot, and the processing unit 15 also synchronously stores the dynamic image in a period during which the photographing unit 13 continues to shoot. A storage unit (for example, a memory card, not shown in the figure) electrically connected to the processing unit 15. Then, the flow proceeds to step S2.

In step S2, the processing unit 15 determines whether an image abnormality condition is met according to the dynamic image by means of image recognition. The image abnormality condition in this embodiment represents that the dynamic image indicates that there is an attachment on the surface 12. If the judgment result of the processing unit 15 is yes, the flow then proceeds to step S3. On the other hand, if the judgment result of the processing unit 15 is no, the processing unit 15 starts again from step S2 at the end of a first interval period. Start execution, and the specific time length of the first interval period is not particularly limited in this embodiment.

Specifically, when a foreign object adheres to the surface 12 to partially obscure the shooting range of the photographing unit 13, because the foreign object is not within the focus range of the photographing unit 13 when shooting, it will cause the dynamic image There are blurry patches of color in. Therefore, in this embodiment, the processing unit 15 can determine whether the image abnormality condition is met at least by detecting whether there are blurred color blocks in the dynamic image, for example. However, the method for determining whether the abnormal condition of the image is met is not limited to the aforementioned method. For example, in other implementations, the processing unit 15 may also compare multiple frames of the dynamic image. Yes, according to whether there are fixed objects in the frames that will not change with the background image to determine whether the abnormal conditions of the image are met, and it is not limited to this embodiment.

In step S3 following step S2, once the processing unit 15 determines that the image abnormality condition is met, the processing unit 15 then uses image recognition to determine whether the attachment on the surface 12 is liquid based on the dynamic image ( For example, water droplets). If the judgment result of the processing unit 15 is yes, the flow proceeds to step S5, on the other hand, if the judgment result of the processing unit 15 is no, the flow proceeds to step S4.

For ease of description, the part of the dynamic image showing the attachment is regarded as an abnormal part, and, in this embodiment, the processing unit 15 may determine, for example, based on the color, brightness, and transparency of the abnormal part. Whether the attachment on the surface 12 is liquid. However, in other embodiments, the processing unit 15 may also determine whether the attachment on the surface 12 is liquid based on the edge definition of the abnormal part, or whether the abnormal part deforms over time, or other methods.

Furthermore, the processing unit 15 can also determine whether the attachment on the surface 12 is liquid, for example, by means other than image recognition. For example, in another embodiment, the photographing device 1 further includes an optical signal transceiving unit (not shown in the figure) adjacent to the surface 12 and electrically connected to the processing unit 15, and the optical signal transceiving unit is It is configured to emit a light signal (for example, infrared) toward the surface 12 and receive a reflection part of the light signal reflected by an object. In this way, if there is an attached object on the surface 12, the attached object will be irradiated by the light signal to increase the intensity of the reflection part. Moreover, when the light transmittance of the solid is lower than that of the liquid, the intensity of the reflection part caused by the solid attachment is usually greater than the intensity of the reflection part caused by the liquid attachment. Therefore, in another embodiment, the treatment The unit 15 can determine whether the attachment on the surface 12 is liquid, for example, through the intensity of the reflective part, and is not limited to this embodiment.

In step S4 following step S3, once the processing unit 15 determines that the attachment on the surface 12 is not liquid, the processing unit 15 controls the vibration unit 14 to output a vibration prompt notification with a first vibration intensity, This prompts the user that there is foreign matter attached to the surface 12. It is added that the first vibration intensity may refer to, for example, the amplitude of the vibration of the vibration unit 14, and the amplitude of the vibration may, for example, be represented as a displacement value (displacement), a velocity value (velocity) or an acceleration value (acceleration). , But not limited to this.

In step S5 following step S3, once the processing unit 15 determines that the attachment on the surface 12 is liquid, the processing unit 15 then determines the area occupied by the liquid attached to the surface 12 in the dynamic image Whether the ratio is higher than a first predetermined percentage, the first predetermined percentage may be implemented as 30%, but is not limited to this. If the judgment result of the processing unit 15 is yes, the processing unit 15 judges that a liquid shielding condition is met, and the flow then proceeds to step S6. On the other hand, if the judgment result of the processing unit 15 is no, the processing unit 15 15 For example, when a second interval period ends, step S2 is executed again, and the specific time length of the second interval period is not particularly limited in this embodiment.

In step S6 following step S5, once the processing unit 15 determines that the liquid shielding condition is met (that is, it is determined that the liquid attached to the surface 12 occupies a higher proportion of the area of the dynamic image in the dynamic image). Percentage), the processing unit 15 performs a vibration control procedure.

Specifically, in the vibration control program of this embodiment, the processing unit 15 controls the vibration unit 14 to vibrate with a second vibration intensity greater than the first vibration intensity, so that the surface 12 follows the vibration unit 14 Vibrate together, and thereby make the liquid attached to the surface 12 detach from the surface 12 with the vibration.

Further, in the vibration control program of the present embodiment, the processing unit 15 controls the vibration unit 14 to suspend vibration at predetermined intervals, and determines a motion image according to the dynamic image while the vibration unit 14 suspends vibration. Whether the liquid separation conditions are met. Specifically, the liquid detachment condition in this embodiment, for example, means that the liquid attached to the surface 12 occupies a proportion of the area of the key image area that is lower than a second predetermined percentage, and the second predetermined percentage can be, for example, The implementation is 10%, but not limited to this. If the processing unit 15 determines that the liquid separation condition is not met, the vibration unit 14 is again controlled to vibrate with the second vibration intensity. On the other hand, if the processing unit 15 determines that the liquid separation condition is met, Then the vibration unit 14 is controlled not to vibrate, and the vibration control procedure ends. That is to say, in this embodiment, the processing unit 15 will control the vibration unit 14 to end the vibration after the key image area of the dynamic image becomes clear, but it is not limited to this.

With the photographing method of this embodiment, when the processing unit 15 of the photographing device 1 judges that the image abnormality condition is met during the photographing process of the photographing unit 13 (that is, when it is judged that there is an attachment on the surface 12), it will Then it is judged whether the attachment on the surface 12 is liquid. When it is judged that the attachment is liquid, the processing unit 15 can use the vibration control program to control the vibration unit 14 to vibrate in a manner with greater vibration intensity, so that the attachment is The liquid on the surface 12 is detached, thereby ensuring the clarity of the dynamic image. On the other hand, when it is determined that the attachment is not liquid, it is difficult for the non-liquid attachment (such as dust or sand) to escape from the surface 12 due to the vibration method. Therefore, the processing unit 15 controls the vibration unit 14 to The vibration prompt notification is output in a manner with a lower vibration intensity to remind the user. It is worth mentioning that because the vibration unit 14 can be implemented as a small vibration motor, this embodiment can ensure that the photographing device 1 maintains a compact size and weight. On the other hand, the vibration unit 14 only needs to be installed in the The inside of the main body 11 can perform the function of detaching the liquid attached to the surface 12. Therefore, in this embodiment, it is not necessary to provide other mechanisms (such as wipers or fans) for removing water outside the main body 11. The embodiment is particularly suitable for applications that mainly require miniaturization and light weight, such as driving recorders or outdoor sports cameras.

In summary, the photographing device 1 can not only detach the liquid attached to the surface 12 by means of automatic vibration, but also automatically output a vibration notification notification when there are non-liquid attachments on the surface 12. Therefore, there is no need to check whether the lens has liquid or other foreign matter remaining, and the inconvenience of the prior art is effectively improved, so the purpose of the invention can be achieved.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
