1 is a functional block diagram of an image capture device according to an embodiment of the present invention. As shown in FIG. 1 , the image capturing device 200 includes a casing 220 , a lens 221 , and a photographing key 222 . The image capturing device 200 further includes a control device 800, a button detecting device 400 and an image sensing device 700 disposed in the casing 220.

Then, the image sensing device 700 is controlled according to the operation modes to obtain a plurality of images.

2 is a flow chart showing the method of operation of an embodiment of the present invention. According to an embodiment of the invention, a method for operating an image capture device is provided for use in an image capture device and is adapted to initiate a plurality of modes of operation using a camera button 222, the method comprising the following steps.

Step S02: Identify a plurality of frequencies that the shooting key 222 is pressed, wherein the frequencies respectively correspond to the operating modes. In an embodiment, the frequencies may include a first frequency, a second frequency, and a third frequency, and the operating modes include a camera mode, a first video mode, and a second video mode, such as sequential It can be camera mode, video mode and short video mode. The first frequency corresponds to a camera mode, the second frequency corresponds to a first video mode, and the third frequency corresponds to a second video mode.

Step S04: Perform the operation modes according to the frequencies, so that the image capturing device acquires a plurality of images. In one embodiment, the photographing mode is performed when it is determined to be the first frequency, the first recording mode is performed when it is determined to be the second frequency, and the second recording mode is performed when it is determined to be the third frequency.

In one embodiment, a plurality of times of the plurality of pressed states and a combination of the intervals between the pressed states. Preferably, the frequency may be a combination of at least one of a first time t1 in which the pressed state is maintained, a second time t2 in which the pressed state is maintained, and an interval time Tin between the two presses.

Preferably, for example, the first time is longer than the second time, and the frequency planning can be designed in accordance with the Morse code.

As shown in Table 1 above, the Morse code is a "two-tone signal" composed of "." (short-sound); and "-" (long-sound). In the present invention, the signal of the sound is changed to a signal of the length of the pressing state. The letter is represented by a long and short signal. When designing according to the international Morse code, the first time is short time and the second time is long time. A combination of short time, interval time and a long time represents A; only one short time combination represents E; only one long time combination represents T, so that three different operation modes can be generated.

However, the design of the frequency of the present invention is not limited to the Morse code. In one embodiment, the first frequency is the first time t1 in which the pressing state is maintained, for example, t1 is 0.3 to 0.6 seconds, which is approximately the time of one press when the camera is to start the camera. At this time, the photographing mode is a photographing operation, and the image capturing device can obtain a screen at this time.

The second frequency is the second time t2 in which the pressed state is maintained, for example, t2 is 1 second. The first recording mode can be a video operation, and the image capturing device starts recording. In an embodiment, the second frequency may also be regarded as including a second time t2 in which the pressing state is maintained, an interval time T between the first pressing state and the second pressing state, and a third time t3 in which the other pressing state is maintained, The third time t3 may be approximately equal to the first time t1. In this embodiment, when the video recording is stopped after the video recording is started, it is detected whether the shooting key 222 is pressed, that is, the third time t3 in which the pressing state is maintained, and the detecting of the shooting key 222 is detected. Stop recording afterwards. At this time, since the image capturing device continuously records the time between the first pressing state and the second pressing state, the period during which the recording is performed is the interval time T between the first pressing state and the second pressing state.

The third frequency is the third time t3 in which the pressed state is maintained, for example, t3 is 2 seconds. At this time, the second video mode can be a short video operation. In an embodiment, under the short recording operation, after the third frequency is measured, the image capturing device may perform recording for a predetermined time Tdef after the third time t3, and the predetermined time Tdef may be, for example, 10 seconds. At this time, depending on the design, the short recording time may be a predetermined time Tdef after the third time t3. In an embodiment, the image capturing device may start recording and continuously recording after detecting that the shooting key 222 is in the pressed state after the second time t2, until after the third time t3, determining to enter the second video. Mode, and then recording a predetermined time Tdef after the second time t2. The short recording time may be an additional time Tdef after the second time t2. For the convenience of explanation, An embodiment incorporating the foregoing steps is referred to as a fixed short video implementation.

However, in the foregoing fixed short video recording embodiment, since the short video recording time is preset and the setting is a fixed value, the user cannot decide to stop the recording time, and the recording time may be too short or too long. It is inconvenient to use.

3 is a flow chart showing an operation method of an embodiment of the present invention. More specifically, as shown in FIG. 3, in an embodiment, the operation method of the image capturing device is as follows. When the user presses the photographing key 222 (step S10), the button detecting device 400 detects that the photographing key 222 is pressed, and continuously detects whether the photographing key 222 is released (step S12). When the determination result in the step S12 is "YES", the photographing operation is performed, and the image of the single image or the image of the plurality of non-continuous images is started to be captured (step S14), at which time the button detecting device 400 actually detects the holding of the pressing. The first time t1 of the state, which is the time normally used for one shot when taking a picture with the camera, is about 0.3 to 0.6 seconds. When the determined result at step S12 is "NO", it is next detected whether or not the pressed state of the photographing key 222 exceeds the time threshold Tth1 (step S16). When the determined result at step S16 is "NO", step S16 is continued. When the determined result at step S16 is YES, the video mode is executed, and the images of the plurality of consecutive portraits are started to be captured (step S18), and it is continuously detected whether or not the photographing key 222 is released (step S20).

When the result of the determination in step S20 is "YES (ie, release state)", the normal recording mode in the recording mode is executed (step S22), and the button detecting means 400 detects the second time t2 in which the pressing state is maintained, approximately 1 second. Subsequently, the key detecting means 400 continuously detects whether the photographing key 222 is pressed (step S24). If the result of the determination in the step S24 is "NO", the process proceeds to a step S24. If the result of the determination in the step S24 is "YES", the normal recording mode is ended and the recording is ended (step S26). When it is detected in step S24 that the photographing key 222 is pressed, it corresponds to a time when the third pressing time t3 in which the pressing state is detected is approximately one pressing time. The start time of the video can start from step 18 or step 22, and the end time of the video is step S26, and the progress time of the video is step 18 or step 22; and the interval time Tin between step S26.

When the result of the determination in step S20 is "NO (ie, continuous pressed state)", it is next detected whether the pressed state of the photographing key 222 exceeds the time threshold Tth2 (step S28). When the determined result at step S28 is "NO", step S28 is continued. When the determined result at step S28 is YES, the short video mode in the recording mode is entered (step S30), and it is continuously detected whether or not the photographing key 222 is released (step S32).

When the determined result at step S32 is "NO", step S32 is continued. When the determined result at step S32 is "YES", the short video mode is ended and the recording is ended (step S34). In the present embodiment, the photographing key 222 is continuously pressed, and the third frequency, that is, the third time t3 in which the pressing state is maintained, for example, 10 seconds. The start time of the video can start from step 18 or step 30, and the end time of the video is step S34, and the progress time of the video is step 18 or step 30; and the interval time Tin between step S34. For convenience of explanation, the embodiment including the foregoing steps is referred to as a non-fixed short video embodiment. Yu Fu In the fixed short video implementation mode, since the end time of the short video mode is the end time of the pressing state, the user can decide the end time of the recording by himself, and avoid the problem that the previous embodiment can only record the predetermined time.

In addition, according to an embodiment of the present invention, a method for starting a short video by using a shooting button 222 is provided, and when the camera has only one shooting button 222, the original short pressing, long pressing, and other functions are not affected. Under the setting, start the short video function. Its operation is as follows:

1. Press the shooting button 222 to exceed the first time threshold t1 of the long press to start the recording mode.

2. Press and hold the camera button 222 after starting the video, and switch to the short video mode when the second time threshold t2 is exceeded.

3. When the previous step is completed, the user should continue to hold down the photography key 222 until the user wants to end the shooting of the short video and release the photography key 222.

From the viewpoint of simple operation, it is preferable to adopt a design of a fixed short video recording mode, and the user does not need to press the photographing key 222 for a long time. However, from the viewpoint of controllability, it is preferable to adopt a non-fixed short video implementation design, and the user can select the time at which the video ends, avoiding the disadvantage that the video is too long or too short.

In an embodiment, the fixed short video implementation aspect can also be integrated; and the non-fixed short video implementation aspect can have the first two advantages at the same time. The details are as follows. 4 is a schematic diagram showing a pressing time and an activation mode according to an embodiment of the present invention. As shown in FIG. 4, when the button detecting device 400 detects When the pressed state of the photographing key 222 exceeds the second time threshold Tth2 and is shorter than the third time threshold Tth3, the camera enters the fixed short video mode, that is, the end time of the short video is preset (predetermined time Tdef). When the button detecting device 400 detects that the pressing state of the shooting button 222 exceeds the third time threshold Tth3, the camera enters the non-fixed short recording mode, that is, the end time of the short recording is that the shooting button 222 is placed from the pressing state. The time point when opening.

The pressed mode frequency of the photographing key 222 is used to determine the operation mode, and other functions can be designed. For example, a typical camera has a continuous shooting mode, that is, several images are taken in succession at a time. This operation usually needs to be set before it can be enabled before restarting. However, according to the present invention, the continuous shooting mode can be activated without setting in advance. More specifically, the user can perform a long press after a short press, for example, three times, and when the photographing key 222 is released, the image capturing device 200 starts to take a plurality of photographs continuously. In an embodiment, the number of consecutive short presses may be calculated, for example, N times and finally the long press. When the shooting key 222 is released, the image capturing device 200 starts to continuously capture N images.

In summary, according to the prior art, when performing multiple modes of operation, a large number of buttons, or prior settings, are required to initiate different modes of operation. However, according to the present invention, the operation mode can be determined according to the frequency at which the photographing key 222 is pressed, so that the user can operate the image capturing device 200. In an embodiment, the image capturing device 200 can also be activated without a hand-held device connection through a simple button operation. Short video feature.
