Snorkeling shooting is a more popular way of photography nowadays. Users can use snorkeling shooting to shoot images including various underwater landforms and scenery. However, at present, the effects of images obtained by processing images that simultaneously exist in the water surface area and the underwater area taken by the snorkeling shooting method are not good.

In view of the foregoing, it is necessary to overcome the current problem of poor processing effects of images in the water surface area and the underwater image area at the same time. In addition, when there are large areas of the same or similar color in the image, it will also cause poor image imaging.

Summary of the invention

In view of the above problems, an image processing method, device, computer readable storage medium, imaging device, and image processing system that overcome or at least partially solve the above problems are proposed.

According to a second aspect of the present invention, there is provided a device including a device processor configured to: determine whether an image to be processed simultaneously has a water surface area and an underwater image area; In the case of a preset condition, the saturation of the water surface image area and/or the underwater image area is adjusted, and the preset condition includes that the image to be processed simultaneously exists in the water surface image area and the underwater image area.

According to a third aspect of the present invention, there is provided a computer-readable storage medium, wherein the computer-readable storage medium stores instructions, and the instructions are used to implement the above-mentioned image processing method.

According to a fourth aspect of the present invention, there is provided an imaging device, the imaging device comprising: an imaging unit: the imaging unit generates an image to be processed; a judgment module: judging whether the image to be processed simultaneously exists in a water surface area; Underwater image area; processing module: in the case that the image to be processed meets a preset condition, adjust the saturation of the water surface image area and/or the water image area, and the preset condition includes the image to be processed The water surface picture area and the water picture area exist at the same time.

According to a fifth aspect of the present invention, there is provided an image processing system, the image processing system comprising: a receiver for receiving an image to be processed; a system processor configured to determine whether the image to be processed simultaneously exists on the water surface A picture area and an underwater picture area; when the image to be processed satisfies a preset condition, the saturation of the water surface picture area and/or the water picture area is adjusted, and the preset condition includes the image to be processed The water surface picture area and the water picture area exist at the same time.

The inventor of the present invention found that the effect of the existing image obtained by processing images that simultaneously exist in the water screen area and the water surface screen area is not good. The reason is that there is a large difference between the water color temperature and the underwater color temperature.

Of course, they are only examples, and are not intended to limit the invention. In addition, the present invention may repeat reference numerals and/or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and/or settings discussed.

This embodiment first provides an image processing method. FIG. 1 is a schematic diagram of an image processing method according to an embodiment of the present invention. Among them, the image to be processed can be either a photo or a video. When the image to be processed is a photo, the image processing method processes the frame of the photo. When the image to be processed is a video, the image processing method processes any frame in the video. Number of photos to be processed. The image processing method includes, but is not limited to, a judgment processing step and a to-be-processed image processing step. Among them, the judgment processing steps include but are not limited to the first judgment sub-step.

As shown in Figure 1, image processing methods include but are not limited to:

S102, the first judgment is divided into steps: judging whether the image to be processed simultaneously exists in the water surface image area and the underwater image area.

S104, the image processing step to be processed: when the judgment result of the judgment processing step is yes, adjust the saturation of the water surface image area and/or the water image area, and the case where the judgment result of the judgment processing step is yes includes but is not limited to the first The judgment result of one judgment step is yes.

In some embodiments, before the first determination step, it further includes but is not limited to acquiring a detection image corresponding to a predetermined number of frames and the image to be processed. When the image to be processed is a photo, the detection image corresponding to the preset number of frames can be obtained. For example, the imaging unit can repeatedly obtain a photo with the same position and angle as the obtained photo, and the photo can also be copied to obtain the preset frame Number of detected images, etc.; when the image to be processed is a video, you can directly obtain a preset number of detected images from the video, or you can copy each frame of photos in the video to get a preset frame for each frame of photos Number of detected images, etc.

Among them, the value of the preset number of frames can be any value from 15 to 25 frames, for example, it can be 1 frame, 2 frames, 3 frames, 4 frames, 5 frames, 6 frames, 7 frames, 8 frames, 9 frames, 10 frames. Frames, 11 frames, 12 frames, 13 frames, 14 frames, 15 frames, 16 frames, 17 frames, 18 frames, 19 frames, 20 frames, 21 frames, 22 frames, 23 frames, 24 frames, 25 frames, etc., among others In the embodiment, the value of the preset number of frames may also be other values.

In the first judging sub-step, when a feature area containing a preset feature appears in the preset number of detected images, and the red channel gain of the feature area is higher than the channel gain threshold, it is judged that the image to be processed has a water surface area.

The preset feature can be water ripples or a certain value of strong light intensity, etc. The specific value of the strong light intensity can be determined according to experimental conditions. Among them, the identification of the preset feature can use methods such as intelligent scene judgment to determine whether the red channel gain of the feature region is higher than the channel gain threshold, and white balance can be combined to determine whether the red channel gain of the feature region is higher than the channel gain threshold. Among them, the value of the channel gain threshold can be determined experimentally. More appropriately, the RGB value falls within the range of [236 232 187] to [255 69 0]. For example, when the RGB value is [255 130 71], [255 165 0], [250 128 114], or [238 118 33], It can be judged to be reddish or orangeish. At this time, the gain of the red channel can be adjusted according to user preference or pre-calibration to achieve an image effect closer to human vision. In particular, it is ideal to adjust the RGB value to [255 255 255] without affecting other colors or the beauty of the picture.

After judging that the image to be processed exists in the water surface area, it can be further determined whether the image to be processed still has an underwater image area, and it can be determined that the image to be processed still exists in the water image area when a blue image is detected in the area outside the water surface area. Wait.

In other embodiments, when the second preset color exists in the image to be processed and the ratio of the frame with the second preset color to the image to be processed is within the preset ratio range, it is determined that the image to be processed exists at the same time Water surface area and underwater area.

Wherein, the second preset color may be blue, such as light blue, dark blue, etc. The preset ratio range can be 70% to 95%, for example, the preset ratio range can be 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, etc., in In other embodiments, the preset ratio range may be other numerical ranges.

It is possible to determine the image to be processed by this way of determining that there is a second preset color in the image to be processed and the proportion of the frame with the second preset color to the image to be processed is within the range of the preset ratio when the light intensity is low. Whether there is a water surface image area and a water image area at the same time, the dark light illumination intensity can be lower than the strong light illumination intensity, and the numerical value of the dark light illumination intensity can be determined by an experimental method.

The judgment processing step may also include, but is not limited to, the color temperature adjustment sub-step. In some embodiments, the color temperature adjustment sub-step may be located before the first judgment sub-step. In other embodiments, the color temperature adjustment sub-step may also be located in the first judgment. After sub-steps.

When the color temperature adjustment sub-step is after the first judgment sub-step, if the judgment result of the first judgment sub-step is yes, the color temperature adjustment process is performed on the image to be processed. Those skilled in the art can understand that when the judgment processing step includes the first judgment step and does not include the second judgment step, the case where the judgment result of the judgment processing step is yes includes the judgment result of the first judgment substep being yes; In the case where the judgment processing step includes the first judgment step and the second judgment step, the case where the judgment result of the judgment processing step is yes includes the judgment result of the first judgment substep is yes and the judgment result of the second judgment substep is Yes. Those skilled in the art can also understand that when the color temperature adjustment sub-step is after the first judgment sub-step, in the image processing step to be processed, what is adjusted is the water surface area and/or water surface of the image to be processed after the color temperature adjustment process is performed. The saturation of the picture area.

When the color temperature adjustment sub-step is before the first judgment sub-step, the color temperature adjustment process is directly performed on the image to be processed.

In the color temperature adjustment sub-steps, the process of adjusting the color temperature of the image to be processed may include, but is not limited to, the process of increasing the color temperature of the image to be processed. The color temperature adjustment step by step can reduce the reddishness of the water surface area of the image to be processed to a certain extent, so that when there are both water surface area and water image area in the image to be processed, the overall visual effect of the image to be processed is better. good.

In some embodiments, the color temperature of the image to be processed can be adjusted by means of automatic white balance, and the color temperature can be increased according to the red channel gain of the water surface area and the weight of the strong light intensity area, for example, when the water surface area is The higher the red channel gain of the area, the higher the color temperature adjustment. When the weight of the strong light intensity area is, the higher the color temperature adjustment, etc., and the range of color temperature adjustment can be based on ensuring that the overall color temperature of the image to be processed is normal And set in accordance with the visual habits of the human eye.

The judgment processing step may also include, but is not limited to, a second judgment sub-step. The second judgment sub-step is after the color temperature adjustment sub-step and the first judgment sub-step. The second judgment step includes, but is not limited to, judging whether the saturation of the first preset color in the water surface image area is greater than the saturation threshold. Wherein, the first preset color may be red and/or orange. Among them, the value of the saturation threshold can be determined by experimental methods. It is also appropriate that the RGB value falls within the range of [236 232 187] to [255 69 0], for example, when the RGB value is [255 130 71], [255 165 0], [250 128 114], or [238 118 33] , It can be judged to be reddish or orangeish. At this time, the saturation of the color can be adjusted according to user preference or pre-calibrated to achieve an image effect closer to human vision. In particular, it is ideal to adjust the RGB value to [255 255 255] without affecting other colors or the beauty of the picture.

In the case that the judgment result of the judgment processing step is no, the second white balance adjustment can be performed on the image to be processed and/or the image to be processed can be output. Those skilled in the art can understand that when the judgment processing step includes the first judgment step and does not include the second judgment step, the case where the judgment result of the judgment processing step is no includes the judgment result of the first judgment substep being no; In the case that the judgment processing step includes the first judgment step and the second judgment step, the case where the judgment result of the judgment processing step is no includes whether the judgment result of the first judgment step is no or the judgment result of the second judgment step is no. This method makes it possible to obtain a better image even if the image to be processed does not simultaneously exist in the water surface area and the water surface area or the first preset color saturation of the water surface area is not greater than the saturation threshold. .

In some embodiments, when the judgment result of the judgment processing step is no, only the second white balance adjustment is performed on the image to be processed. In other embodiments, when the judgment result of the judgment processing step is no, Only the image to be processed is output. In other embodiments, when the judgment result of the processing step is no, the image to be processed is adjusted for the second white balance and the image to be processed is output, that is, the image to be processed is first performed 2. Adjust the white balance, and then output the image to be processed.

The second white balance processing can use white patch (white spot) algorithm or gray world (gray world) algorithm, etc., since these algorithms themselves are well known by those skilled in the art, they will not be described in detail here.

In some embodiments, adjusting the saturation of the water surface image area and/or the water image area may include, but is not limited to, reducing the red and/or orange saturation of the water surface image area, that is, it may only reduce the red saturation of the water surface image area. Degree, or only reduce the orange saturation of the water surface area, or reduce the red and orange saturation of the water surface area at the same time.

In other embodiments, adjusting the saturation of the water surface image area and/or the water image area may include, but is not limited to, increasing the blue saturation of the water image area.

Adjusting the saturation of the water surface image area and/or the underwater image area may also include, but is not limited to, adjusting the saturation of the water surface image area and/or the underwater image area in a manner set by the user. For example, the user can set the method to reduce the red saturation of the water surface area, the user can also set the method to reduce the orange saturation of the water surface area, and the user can also set the method to reduce the red and orange saturation of the water surface area at the same time. The user can also set the way to increase the blue saturation of the water screen area, and the user can also set the way to reduce the red saturation of the water screen area and increase the blue saturation of the water screen area. The user can also set The method of reducing the orange saturation of the water surface image area and increasing the blue saturation of the underwater image area, the user can also set the method of reducing the red and orange saturation of the water surface image area and increasing the blue saturation of the underwater image area, etc.

In addition, the user can also set the degree of saturation adjustment, for example, the degree of reducing the red saturation of the water surface image area, the degree of reducing the orange saturation of the water image area, the degree of increasing the blue saturation of the underwater image area, and so on.

This method makes the image processing method more intelligent, and can adjust the saturation of the water surface image area and/or the water image area according to the user's preference, which improves the user experience.

In some embodiments, the processing step of the image to be processed may also include but is not limited to a recording step. The recording step includes but is not limited to recording the completed operation of adjusting the saturation of the water surface area and/or the water image area. Moreover, in the image processing step to be processed, the operation of adjusting the saturation of the water surface image area and/or the water image area is performed according to the recording result of the recording step.

For example, when the recording result of the recording step indicates that the operation of adjusting the saturation of the water surface image area and/or the water image area has been completed, the way to reduce the red saturation of the water surface image area is the most, then in the image processing step to be processed, The operation of adjusting the saturation of the water surface image area and/or the water image area is to reduce the red saturation of the water surface image area.

For another example, when the recording result of the recording step indicates that the operation of adjusting the saturation of the water surface image area and/or the water image area has been completed, the way to reduce the orange saturation of the water surface image area is the most, then the image processing step to be processed , The operation of adjusting the saturation of the water surface image area and/or the water image area is to reduce the orange saturation of the water surface image area.

For another example, when the recording result of the recording step indicates that in the completed operation of adjusting the saturation of the water surface image area and/or the water image area, the way to increase the blue saturation of the water image area is the most, then the image processing step to be processed , The operation of adjusting the saturation of the water surface image area and/or the underwater image area is to increase the blue saturation of the underwater image area or the like.

This method makes the image processed by the image processing method more suitable for the user's preferences, and does not require manual operation by the user to select the preferred method, which greatly improves the user experience.

The image processing method may further include but is not limited to a reprocessing step. The reprocessing step includes, but is not limited to, adjusting the hue and/or feathering of the water surface image area.

In some embodiments, only the water surface image area can be adjusted hue processing; in other embodiments, only the water surface image area can be feathered; in other embodiments, the water surface image area can be adjusted at the same time. Eclosion treatment.

Adjusting the hue can prevent the color from being adjusted to distortion, and the feathering process makes the connection of the various areas of the image to be processed more natural, and improves the overall visual effect of the image to be processed.

The reprocessing step may be performed after the image processing step to be processed, and the feathering process may be performed on the edge of the water surface image area and/or the water image area, so that the connection between the water surface image area and the water image area is more natural.

The image processing method may further include, but is not limited to, a white balance processing step. The white balance processing step includes, but is not limited to, performing a first white balance adjustment on the water surface image area.

The white balance processing step can be executed after the reprocessing step. The first white balance adjustment can be performed on the water surface image area with the underwater image area as a reference to further reduce the reddish phenomenon of the water surface image area.

Wherein, the first white balance processing may be the same as the second white balance processing, or may be different from the second white balance processing. The first white balance processing can use a white patch (white spot) algorithm or a gray world (gray world) algorithm, etc.

When using the white patch algorithm, it can not only retain the bluish color in the water image area, but also reduce the red in the water surface image area, so that the overall color temperature and image color are closer to reality.

When using the gray world algorithm, the image to be processed can be partitioned, and the standard deviation of each area can be calculated. A large standard deviation indicates that the corresponding area has richer colors. The statistical weight of the area with a large standard deviation can be increased to ensure The blue of the picture area in the water.

Since the saturation of the water surface image area and/or the water image area has been adjusted, the water image area during the first white balance processing is less affected by the redness of the water surface image area, which can ensure that the water surface image area does not become reddish. It can also ensure that the color of the image area in the water is close to real.

This image processing method adjusts the saturation of the water surface image area and/or the water image area of the to-be-processed image that simultaneously exists in the water surface image area and the water image area, which can effectively solve the problem that the above-mentioned image simultaneously exists in the water image area and the water surface image area. Sometimes, the red saturation of the water surface image area is too high, which leads to the problem that the image effect of the water image area and the water surface image area is not good at the same time. This image processing method can also obtain a better image when there are both a water surface area and an underwater image area in the image to be processed, which improves the image quality and user experience of the image to be processed.

S216: Output the image to be processed.

S218: Perform a second white balance adjustment on the image to be processed. Therefore, even in the case that the image to be processed does not have a water surface area and a water image area at the same time, an image with a better effect can be obtained. Step S216 is executed after step S218.
