In today's information age, human dependence on electronic devices is increasing. For example, portable electronic devices with camera functions have gradually become mainstream, and have become an indispensable tool in modern people's lives. In recent years, various image capturing devices (such as conventional cameras, digital cameras, mobile phones with image capturing functions, etc.) have been used more and more widely. Among them, in order to allow the user to take a more vivid image, or let the user capture a precious picture, the continuous shooting function is widely installed in the image capturing device. For example, in order to capture moving objects, such as birds in flight or children in play, the continuous shooting function allows the user to obtain a series of continuous shooting images by simply pressing the shutter button once. Then, the user can select the most satisfactory image from the plurality of continuous shooting images. In addition, the continuous shooting function also allows users to avoid the cause In the case where it is necessary to press the shutter button a plurality of times and miss the opportunity to take the best image.

However, although the continuous shooting function allows the user to take a more satisfactory image, when the user wants to edit or process the photos generated by the continuous shooting function, a large number of continuous shooting photos cause editing operations on the user. The burden. For example, if the user wants to delete a series of continuous shooting images, the user can only select and delete one by one, which makes the user feel time consuming and laborious. On the other hand, since the continuous shooting image is the image captured by the user for the same scene and the same theme, the user often wants to perform the same image processing on the same series of continuous shooting images, for example, adjusting the brightness of all the continuous shooting images. However, in general, the number of photos produced by the continuous shooting function is very large. If the user edits each continuous shooting image one by one, the user will feel a great burden in use.

In view of the above, the present invention provides an image processing method and an image capturing device, so that the user does not need to sequentially edit multiple consecutive shooting images, so that the same series of continuous shooting images can be edited and improved. The user edits the convenience of processing the continuous shooting image.

The present invention provides an image processing method suitable for an image capturing device. The image processing method includes the following steps. First, the shutter signal is detected to continuously capture a plurality of continuous shooting images. Next, the identification data is written to the information file of each continuous shooting image. Then, an editing operation for at least one target image of the plurality of continuous shooting images is received. Then, the first image processing is performed on the target image, and the second image processing is performed on the other continuous shooting images having the same identification data according to the identification data in the information file of the target image.

The invention provides an image capturing device, which comprises an image capturing module, a data writing module, an operation receiving module and an image processing module. The image capture module detects the shutter signal and continuously captures multiple continuous shooting images. The data writing module writes the identification data to the information file of each continuous shooting image. The operation receiving module receives an editing operation for at least one target image in the continuous shooting image. The image processing module performs the first image processing on the target image, and performs the second image processing on the other continuous shooting images having the same identification data according to the identification data in the information file of the target image.

Based on the above, the present invention can generate the correlation between the captured images captured under the same shutter signal by writing the identification data into the information file of the continuous shooting image when capturing the continuous shooting image. When the image capturing device receives the user's editing operation on at least one target image in the continuous shooting image, the image capturing device can simultaneously perform the same or different image processing on all the continuous shooting images with the same identification data.

When the user uses the continuous shooting function of the image capturing device to capture an image, the user can continuously capture multiple consecutive images by pressing the shutter button once. According to the present invention, when the image capturing device detects a shutter signal and continuously captures an image, an identification data is generated and stored in the information file of each continuous shooting image. In this way, when the user wants to edit or process multiple continuous shooting images, it is only necessary to issue an editing command to one of the continuous shooting images, so that the continuous shooting image with the same identification data can also reach the image editing or image at the same time. The effect of processing. In order to clarify the content of the present invention, the following examples are given as examples in which the present invention can be implemented.

1 is a side view of an image capturing device according to an embodiment of the invention. Block diagram. Referring to FIG. 1 , the image capturing device 100 is an electronic device having a function of capturing images, such as a digital camera, a digital camera, a tablet PC, a smart phone, and the like, and has an image capturing device with a continuous shooting function. The invention is not limited thereto. The image capturing device 100 includes an image capturing module 110, a data writing module 120, an operation receiving module 130, and an image processing module 140.

The image capturing module 110 can include a lens, a photosensitive element, an aperture, and the like. The lens is, for example, a standard lens, a wide-angle lens, and a zoom lens. The photosensitive element is, for example, a Charge Coupled Device (CCD), a Complementary Metal-Oxide Semiconductor (CMOS) element or the like, and the lens and the photosensitive element or a combination thereof are not limited herein. When the image capturing module 110 detects the shutter signal, the image capturing module 110 continuously captures a plurality of continuous shooting images.

On the other hand, the data writing module 120, the operation receiving module 130, and the image processing module 140 can be implemented by software, hardware, or a combination thereof, and are not limited herein. The software is, for example, a source code, an application software, a driver, or a software module or function specifically for implementing a specific function. The hardware is, for example, a central processing unit (CPU), a programmable controller, a digital signal processor (DSP), or other programmable general purpose or special purpose microprocessor ( Microprocessor) and so on.

In this embodiment, the data writing module 120 can write the identification data into the information file of the continuous shooting image, and the information file of the image is, for example, an Exchangeable Image File (EXIF) file, but the present invention Not limited to this. One In general, the information about the image is stored in its EXIF file. This EXIF file is usually generated when the image capture device captures the image, except that it includes a thumbnail for displaying on the screen. It also includes image information such as image file name, file time, shooting time, size, rotation angle and effect. Further, the present invention can make the same series of continuous shooting images can be related by writing the same identification data into the information files of the same series of continuous shooting images. In this way, the user only needs to issue an editing processing instruction to a continuous shooting image, so that other continuous shooting images can also be edited or processed at the same time.

2 is a flow chart of an image processing method according to an embodiment of the invention. Referring to FIG. 1 and FIG. 2 simultaneously, the method of the present embodiment is applied to the image capturing device 100 described above. The following describes the detailed steps of the image processing method of the present embodiment.

First, in step S210, the image capturing module 110 detects the shutter signal to continuously capture a plurality of continuous shooting images. Generally, the shutter signal is a signal generated by the user pressing the shutter button (not shown) of the image capturing device 100. When the image capturing module 110 detects the shutter signal, it represents the user's action to perform image capturing. In this embodiment, the continuous shooting mode is, for example, a manner in which the image capturing device 100 can repeatedly capture at a set interval, that is, the image capturing device 100 can continuously capture multiple images when the shutter button is pressed once. The shooting method, and the interval between consecutive shots depends on the actual application. For example, when the user wants to take an object that moves faster, the interval may fall within the range of 200 milliseconds to 330 milliseconds.

Next, in step S230, the data writing module 120 writes the information file of the identification data in each continuous shooting image. In detail, the image information file is generally generated simultaneously when the image capturing device 100 captures an image. Therefore, the data writing module 120 can write the same identification data into the information files of the respective continuous shooting images captured under the same shutter signal when capturing the image. For example, the information file of the continuous shooting image may be an EXIF file, and the EXIF file has a plurality of fields for storing various data of the image. In this embodiment, the data writing module 120 can write the identification data to the ikey field in the EXIF file, but the invention is not limited thereto.

It is worth mentioning that the purpose of identifying data is to make the same series of continuous shooting images related, so the identification data is not limited to a specific production mode or format. For example, in an embodiment, the data writing module 120 obtains the time information of detecting the shutter signal, and writes the time information as the identification data into the information file of each continuous shooting image. In simple terms, for the same series of continuous shooting images, the image is taken based on the user pressing the shutter button once, so the time information of the shutter signal should be consistent. Therefore, the data writing module 120 can use the time information of the shutter signal as the identification data of each continuous shooting image. In other words, the continuous shooting image with the same time information of the shutter signal represents the same series of continuous shooting images.

In another embodiment, the data writing module 120 can generate random random numbers and write random random numbers as identification data into the information files of the respective continuous shooting images. In brief, when the image capturing module 110 performs the continuous shooting function and continuously captures the image, the data writing module 120 can generate an unused random digital number as the identification data. In other words, different series of continuous shooting images taken under different shutter signals will Different random random numbers are used as identification data, and the same series of continuous shooting images will have the same random random numbers as identification data.

Then, in step S250, the operation receiving module 130 receives an editing operation for at least one target image in the continuous shooting image. In detail, when the user wants to edit or otherwise process the continuous shooting image, one or more target images are selected from the plurality of continuous shooting images, and the operation receiving module 130 is subjected to an editing operation. When the operation receiving module 130 receives the editing operation, the editing operation is converted into a corresponding operation instruction, so that the image processing module 140 can perform the corresponding action according to the operation instruction.

Next, in step S270, the image processing module 140 performs the first image processing on the target image, and performs the second image processing on the other continuous shooting images having the same identification data according to the identification data in the information file of the target image. In detail, when the operation receiving module 130 converts the editing operation into a corresponding operation instruction, the image processing module 140 performs the first image processing on the target image according to the operation instruction. As can be seen from the above, the same series of continuous shooting images will have the same identification data. Based on the identification data in the information file of the target image, the image processing module 140 can know which images are the same series of continuous shooting images as the target image, and perform the second image processing on other continuous shootings with the same identification data. image.

It should be noted that the first image processing and the second image processing may be the same image processing, or may be different image processing, and the invention is not limited thereto. For example, in an embodiment, the first image processing is the same as the second image processing, and may include image editing processing such as adjusting a rotation angle, brightness, contrast, color temperature, or white balance. In other words, when the user wants to edit multiple continuous shooting images of the same series, For example, to adjust the brightness of a continuous shooting image, at least one target image can be selected from a plurality of continuous shooting images for editing. The image processing module not only performs image processing on the target image, but also performs the same image processing on other continuous shooting images with the same identification data, so that the same series of continuous shooting images can also obtain the same editing effect. .

In addition, it is worth mentioning that the operation interface of the general image capturing device has a function for the user to select or mark the image, so that the image processing module 140 performs image processing on the image selected or marked by the user. Therefore, the present invention can be further implemented as follows: when the user selects or marks at least one target image in the continuous shooting image, other continuous shooting images with the same identification data will also be checked or already The status of the label. In this way, the image processing module 140 can perform the same or different image processing on the same series of continuous shooting images. In brief, after all the continuous shooting images are in the checked or marked state, the image processing module 140 can perform the same image processing on all the continuous shooting images, such as deleting all the series of the same series at one time. Shoot images, etc.

In another embodiment, the first image processing and the second image processing may be different image processing methods. For example, the image processing module 140 can retain the target image and delete other continuous shooting images. In detail, as described above, the user can check or mark at least one target image so that all the continuous shooting images with the same identification data are in a checked or marked state. After the continuous shooting image of the same series shows the checked or marked state, the user can cancel the check or mark of at least one target image. The image processing module 140 can be checked accordingly. Or the marked continuous shooting image is deleted, and the remaining target image is retained. In simple terms, the user can select all the images of the entire continuous shooting series by selecting only at least one image. Then, the image that the user wants to keep is deselected, and then the remaining selected image is deleted at one time. Accordingly, with the image processing method of the present invention, the continuous shooting photos obtained under one shutter signal can be correlated to simplify the operation steps for the user to edit multiple consecutive photos.

FIG. 3 is a detailed flowchart of step S250 of FIG. 2 according to an embodiment of the present invention, but the embodiment of step S250 of FIG. 2 shown in FIG. 3 is merely an exemplary embodiment, and the present invention is not limited thereto. . Referring to FIG. 1 and FIG. 3 simultaneously, in the embodiment, the operation receiving module 130 is, for example, a display device integrated with the touch panel in the image capturing device 100, and can simultaneously provide display and input functions. The operation receiving module 130 can be used to display a plurality of images captured by the image capturing device 100, and receive an external editing operation or a user operation.

First, in step S310, the operation receiving module 130 displays the plurality of images captured by the image capturing device 100. In brief, after the image capturing device 100 captures the image, multiple images are displayed by the operation receiving module 130 for the user to view. The plurality of images displayed by the receiving module 130 include not only the current captured image, but also multiple images captured by the image capturing device 100 at other times or other shutter signals. Next, in step S330, the operation receiving module 130 receives a first selection operation for one of the continuous shooting images in the plurality of images to display the continuous shooting image. Further, in order to facilitate the user to select or view the image captured by the image capturing device 100, the operation receiving module 130 may only display the series of consecutive shooting images separately. Instead of displaying all the images in the series of continuous shooting images, one or part of the images in the image.

Therefore, when the operation receiving module 130 receives the first selection operation for one of the consecutive images in the plurality of images, the operation receiving module 130 further displays all the continuous shooting images having the same identification data as the selected image. . In this way, the operation receiving module 130 can display the plurality of images captured by the image capturing device 100 to the user in a clearer and more concise manner. Then, in step S350, the operation receiving module 130 receives a second selection operation for the target image in the continuous shooting image to perform the first image processing on the target image. In brief, the operation receiving module 130 can further select the desired image to be edited or processed by displaying all the continuous shooting images of a part or a group of the plurality of consecutive shooting images selected by the user. image. Based on this, the user can select a target image from a plurality of continuous shooting images and apply a second selection operation. Then, the operation receiving module 130 receives the second selection operation for the target image in the continuous shooting image, so that the image processing module 140 performs the first image processing on the target image. Therefore, since the continuous shooting image of the present invention has the same identification data, not only the continuous shooting effect with the same identification data can simultaneously obtain the effect of image editing or processing, but also the operation receiving module 130 can be more clear and concise. The way to display a large number of continuous shooting images to the user.

Like image_c1 and image image_d1. In the present embodiment, each of the display images image_a1 to image_d1 is, for example, the first image captured by the image capturing device 100 in each series of continuous shooting images, but the invention is not limited thereto. In this embodiment, it is assumed that the user applies a first selection operation to the image image_d1, and the user wants to view or edit all the continuous shooting images in the same series as the image image_d1. Then, after the image capturing device 100 receives the first selection operation for the image image_d1, the image capturing device 100 further displays all the continuous shooting images image_d1~image_d8 in the same series as the image image_d1 according to the identification data of the image image_d1, such as Figure 4B shows.

After the user has viewed the continuous shooting images image_d1~image_d8, the user may want to edit the continuous shooting images image_d1~image_d8, such as adjusting the contrast or brightness of the image. In this embodiment, it is assumed that the image capturing device 100 receives the second selection operation for the continuous shooting image image_d8, and the image capturing device 100 performs the first image processing on the image image_d8. In addition, the image capturing device 100 will simultaneously perform the same or different second image processing as the first image processing on the continuous shooting images image_d1 to image_d7 having the same identification data. In a simple example, when a user shoots a series of ambiguous continuous shooting images image_d1~image_d8 due to a shock, the user only needs to apply a selection action to image_d8 and issue a delete command. Delete all CS images image_d1~image_d8 with the same identification data.

In summary, the image processing method and the image capturing device provided by the present invention use the image capturing device to continuously capture multiple consecutive images while identifying data. Write to the information file of the continuous shooting image to correlate the same continuous shooting images captured under the shutter. In this way, when the image capturing device receives the editing command for one of the continuous shooting images and performs image processing on the image capturing device, the image capturing device can also perform the same or the same for other continuous shooting images having the same identification data.
