[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0034] In the accompanying drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this disclosure. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure. The embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0035] The image capture method provided in this disclosure is applied to the field of computer vision. The image capture method provided in this disclosure is mainly used when the camera application of an electronic device is in a preset mode, and when it detects that the current focusing distance is greater than or equal to a first focusing distance and less than a second focusing distance, it controls the first lens to use a small aperture for image capture. With the development of electronic device technology, more and more electronic devices have lenses with adjustable aperture sizes, enabling the images obtained by the electronic device through the capture operation to meet the imaging requirements.

[0036] In related technologies, controlling the aperture size of a lens during a shooting scene is primarily based on adjusting the aperture size according to the lighting conditions of the shooting environment, thereby controlling the amount of light entering the lens and performing the shooting operation. However, due to the optical characteristics of lenses, aperture size affects the depth of field. While a large aperture can increase the amount of light entering the lens, it also results in a shallower depth of field. This makes it easier for objects with significant changes in focus distance to be blurred, resulting in only part of the acquired image being clearly visible while other parts are blurred, thus producing a noticeable bokeh effect.

[0037] In view of this, the present disclosure provides an image capturing method, which, when the current focusing distance is between a first focusing distance and a second focusing distance, calls a lens with aperture size condition function and uses a first lens with an aperture smaller than the threshold to capture the image, thereby avoiding blurring of the captured image due to a large aperture.

[0038] Figure 1 This is a flowchart illustrating an image capturing method according to an exemplary embodiment, such as... Figure 1 As shown, it includes the following steps.

[0039] In step S11, in response to the camera application of the electronic device being in a preset mode, and the current focus distance being greater than or equal to the first focus distance and less than the second focus distance, the first lens is invoked.

[0040] In this embodiment of the disclosure, the first focusing distance is used to characterize the focusing distance threshold for lens switching. It can be configured that when the current focusing distance is detected to be greater than or equal to the first focusing distance, the first lens is used for shooting; when the current focusing distance is detected to be less than the first focusing distance, other lenses in the electronic device are used for shooting.

[0041] In this embodiment of the disclosure, the second focusing distance is used to characterize the focusing distance threshold of the aperture adjustment strategy. It can be configured that when the current focusing distance is detected to be greater than or equal to the first focusing distance and less than the second focusing distance, the first lens is controlled to use aperture adjustment strategy 1 for shooting; and when the current focusing distance is detected to be greater than the second focusing distance, the first lens is controlled to use aperture adjustment strategy 2 for shooting.

[0042] In this embodiment, the first lens supports shooting with different apertures. The camera application of the electronic device can be a built-in camera application or a third-party application installed on the electronic device. The preset mode can be a mode primarily focused on achieving a high degree of clarity, such as a document recognition mode or an object recognition mode.

[0043] In this embodiment, the image capture method can be applied to the document recognition mode in the camera application of electronic devices, ensuring that the captured document image does not suffer from the blurring effect caused by a large aperture, thus improving the processing effect of image cropping and Optical Character Recognition (OCR) operations based on the acquired document image. The document mode function mainly uses image processing and text recognition technologies. Image processing mainly uses an intelligent scanning engine to perceive the image and restore the layout, such as noise reduction, binarization, and tilt correction, to improve the accuracy and speed of text recognition. The text recognition technology uses OCR technology to recognize and extract the text in the image and convert it into an editable text format, making it convenient for users to edit and organize.

[0044] In step S12, the first lens is controlled to use an aperture smaller than the aperture threshold to capture an image.

[0045] In this embodiment, the aperture threshold is a preset aperture information representing a small aperture. For example, in a traditional shooting scenario, the aperture f-value used by the first lens in the preset mode is f / 1.42, so the preset aperture can be set to f / 4.0. Here, the f-value (f-stop), also known as the aperture value, is a numerical value used to characterize the size of the lens aperture, representing the ratio of the diameter of the lens aperture opening to the lens focal length. An aperture of f / 4.0 is smaller than an aperture of f / 1.42. It should be understood that the specific aperture parameters described above are for illustrative purposes only, and this embodiment does not limit the lens threshold or the specific aperture value of an aperture smaller than the aperture threshold.

[0046] In this embodiment, the aperture size affects the distance at which a clear image can be obtained during shooting. For example, f / 4.0 can clearly capture objects between 12cm and 20cm, while f / 1.42 can only clearly capture objects between 18cm and 20cm. Therefore, using a smaller aperture allows for the acquisition of a clear image with more details. Consequently, this embodiment can reduce the blurring caused by depth-of-field effects and improve the clarity of the captured image.

[0047] In this embodiment of the disclosure, when it is detected that the current focusing distance is less than the first focusing distance or the current focusing distance is greater than or equal to the second focusing distance, an image can be captured using a lens other than the first lens or by using the first lens to determine the aperture based on other factors.

[0048] In this embodiment of the disclosure, in response to the camera application of the electronic device being in a preset mode and the current focusing distance being less than the first focusing distance, a second lens is used for image capture. The second lens has a larger field of view (FOV) than the first lens; for example, the second lens could be an ultra-wide-angle lens in the electronic device, capable of providing a very wide field of view, allowing for the capture of a wider scene when the current focusing distance is less than the first focusing distance.

[0049] In one exemplary embodiment, the document recognition pattern in the camera application is as follows: Figure 2 As shown, Figure 2 This is a schematic diagram illustrating a document recognition pattern according to an exemplary embodiment. Figure 2 In the viewfinder, the video stream data captured by the lens can be displayed. When the trigger operation of the circular shutter button is detected, the image stream data captured by the lens is obtained and saved. It should be understood that the document recognition mode can be a special shooting mode based on user triggering within the camera application, or it can be the only application containing this function, directly using the document recognition mode to take pictures in response to the application's launch.

[0050] In this embodiment of the disclosure, in response to the camera application of the electronic device being in a preset mode and the focusing distance being greater than or equal to a second focusing distance, the aperture size of the first lens is determined based on the lighting conditions acquired by the first lens, and the first lens is controlled to use the aperture size for image capture. As the focusing distance increases, the blurring effect caused by a large aperture weakens. When the focusing distance is greater than the second focusing distance, the first lens can be controlled to adjust the aperture based on the lighting conditions of the shooting environment. For example, if the lighting in the shooting environment is detected to be greater than a preset lighting threshold, the aperture can be reduced to decrease the amount of light entering the first lens and avoid overexposure of the captured image; if the lighting in the shooting environment is detected to be less than the preset lighting threshold, the aperture can be increased to increase the amount of light entering the first lens and avoid underexposure of the captured image.

[0051] It should be understood that the image quality of the second lens of an electronic device is inferior to that of the first lens. When shooting at close range, the shooting lens automatically switches from the first lens to the second lens. Due to hardware differences, the image quality of the second lens is significantly less clear than that of the first lens. In this embodiment, an aperture smaller than the aperture threshold can be used for shooting. Compared to traditional solutions, this allows for shooting at a closer focusing distance using the first lens, enhancing the clarity of the captured image. For example, in traditional solutions, controlling the first lens to use the default aperture only allows for image shooting at a focusing distance greater than 15cm. The image shooting method provided in this disclosure, which controls the first lens to use an aperture smaller than the aperture threshold, allows for shooting at a focusing distance of 12cm-20cm, avoiding the image jump caused by switching lenses at 15cm and improving the shooting experience.

[0052] In this embodiment of the disclosure, the aperture smaller than the aperture threshold can be the smallest aperture supported by the first lens.

[0053] Figure 3 This is a flowchart illustrating an image capturing method according to an exemplary embodiment, such as... Figure 3 As shown, it includes the following steps.

[0054] Figure 3 Step S21 and Figure 1 The steps in step S11 are the same and will not be repeated here. Please refer to the relevant descriptions in the above embodiments. The following only describes the differences.

[0055] In step S22, the first lens is controlled to use the smallest aperture supported by the first lens to capture an image.

[0056] In this embodiment, the smaller the aperture, the greater the depth of field of the first lens. Depth of field (DoF) is the depth of the space in front of and behind the focal point of the object being photographed, where the image is relatively sharp. Therefore, the smallest aperture usable by the first lens can be used for image acquisition, allowing the most sharp objects to be captured during close-up shooting.

[0057] In this embodiment, the aperture size corresponding to the current focusing distance can also be determined by the correspondence between focusing distance and aperture. When the electronic device is in a preset mode and the current focusing distance is greater than or equal to the first focusing distance and less than the second focusing distance, the aperture size corresponding to the current focusing distance can be determined by the correspondence. This allows for appropriately increasing the aperture of the document when the distance between the electronic device and the object being photographed is relatively far, thereby increasing the amount of light entering the first lens and improving the quality of the captured image.

[0058] Figure 4 This is a flowchart illustrating an image capturing method according to an exemplary embodiment, such as... Figure 4 As shown, it includes the following steps.

[0059] Figure 4 Step S31 and Figure 1 The steps in step S11 are the same and will not be repeated here. Please refer to the relevant descriptions in the above embodiments. The following only describes the differences.

[0060] In step S32, based on the correspondence between focusing distance and aperture, an aperture that matches the current focusing distance is determined.

[0061] In this embodiment of the disclosure, the correspondence includes an aperture smaller than the aperture threshold and includes at least two different focusing distances, wherein the at least two different focusing distances include a third focusing distance and a fourth focusing distance, the third focusing distance being smaller than the fourth focusing distance, and the third focusing distance being smaller than the fourth focusing distance.

[0062] In an exemplary embodiment, the correspondence between focusing distance and aperture is as follows: Figure 5 As shown, Figure 5 This is a schematic diagram illustrating the correspondence between focusing distance and aperture according to an exemplary embodiment. Figure 5 In this example, the object being photographed is a paper document, the first focusing distance is 12cm, the second focusing distance is 20cm, and the aperture threshold is f / 1.42. Therefore, the aperture can be set to f / 4.0 for a focusing distance of 12cm-15cm, f / 2.8 for a focusing distance of 15cm-18cm, and f / 2.0 for a focusing distance of 18cm-20cm.

[0063] In one exemplary embodiment, taking a document recognition mode as a preset mode as an example, the document recognition mode shooting method in the related art is as follows: Figure 6 As shown, Figure 6 This is a schematic diagram illustrating a shooting process in a related art according to an exemplary embodiment.

[0064] exist Figure 6In this system, when the camera application of an electronic device is triggered to take a picture in document recognition mode, it uses the original image magnification (1x) and uses a laser autofocus sensor to obtain the current focus distance. It determines whether the current focus distance is less than 15cm (the first focus distance). If the current focus distance is less than 15cm, it uses the ultra-wide-angle lens (the second lens) to take the picture, including displaying a preview in the viewfinder and acquiring the corresponding image content in response to the image acquisition operation. If the current focus distance is greater than or equal to 15cm, it uses the main camera lens (the first lens) to take the picture, including displaying a preview in the viewfinder and acquiring the corresponding image content in response to the image acquisition operation. In response to the image content obtained using the main camera lens or the ultra-wide-angle lens, the intelligent scanning engine performs image perception and layout reconstruction. The reconstructed image content is then processed using OCR technology to recognize and extract text from the image and convert it into an editable text format for easy editing and organization by the user.

[0065] In one exemplary embodiment, taking a document recognition mode as a preset mode as an example, the document recognition mode image capturing method in this embodiment of the disclosure is as follows: Figure 7 As shown, Figure 7 This is a schematic diagram illustrating a shooting process according to an exemplary embodiment.

[0066] exist Figure 7 In this system, when the camera application of an electronic device is triggered to take a picture in document recognition mode, it uses the original image magnification (1x) and uses a laser autofocus sensor to obtain the current focus distance. It determines whether the current focus distance is less than 12cm (the first focus distance). If the current focus distance is less than 12cm, it uses the ultra-wide-angle lens (the second lens) to take the picture, including displaying a preview in the viewfinder and acquiring the corresponding image content in response to an image acquisition operation. If the current focus distance is greater than or equal to 12cm, it uses the main camera lens (the first lens) to take the picture and further determines whether the current focus distance is greater than or equal to 12cm (the first focus distance) and less than 20cm (the second focus distance). If the current focus distance is greater than or equal to 12cm and less than 20cm, it controls the main camera to determine the aperture based on the correspondence between focus distance and aperture. In this correspondence, the closer the distance, the smaller the aperture; the farther the distance, the larger the aperture. The picture taking includes displaying a preview in the viewfinder and acquiring the corresponding image content in response to an image acquisition operation. If the current focusing distance is greater than 20cm, the main camera will determine the aperture based on the lighting conditions and use that aperture to take a picture. The shooting includes displaying a preview in the viewfinder and acquiring the corresponding image content in response to the image acquisition operation.

[0067] In one exemplary embodiment, taking document recognition mode as an example, the effect of image capture using the default aperture is as follows: Figure 8 As shown, Figure 8 This is an image rendering illustrating how to control a first lens to take a picture using a default aperture, according to an exemplary embodiment. Figure 8 In the previous example, due to the use of the default aperture, there was a phenomenon where the image content corresponding to the current focus distance (i.e., the text at the bottom) was clear, while the image content not corresponding to the current focus distance (i.e., the text at the top) was blurry. However, this disclosure achieves the same effect by using an aperture smaller than the aperture threshold for image capture. Figure 9 As shown, Figure 9 This is an image effect diagram illustrating, according to an exemplary embodiment, controlling a first lens to use an aperture smaller than the aperture threshold for shooting. Figure 9 In this process, by using an aperture smaller than the aperture threshold for shooting, the focusing distance range that can capture clear image content is increased, resulting in all text content in the obtained image being clear.

[0068] In this embodiment of the present disclosure, when the camera application of the electronic device is in a preset mode and detects that the current focusing distance is greater than or equal to the first focusing distance and less than the second focusing distance, the first lens that can adjust the aperture size is controlled to use an aperture smaller than the aperture threshold for shooting, thereby reducing the blurring phenomenon caused by the large aperture during shooting and improving the clarity of the captured image.

[0069] Based on the same concept, embodiments of this disclosure also provide an image capturing device.

[0070] It is understood that the image capturing device provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software.

Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of this disclosure.
