Description

[0002] With the development of current shooting technology, users' requirements for the quality of shooting results are also gradually increasing. However, many novice users find it difficult to compose shots because they don't know how to control the subject distance (the distance between the object and the shooting lens), or they find it difficult to use the desired focal length to shoot specific scenes due to environmental limitations. Different shooting scenes and needs have different requirements for subject distance. By precisely controlling the shooting distance, you can ensure the sharpness of the image and the composition effect.

[0003] Currently, it is difficult for users to intuitively determine the optimal shooting distance. They usually need to repeatedly adjust the shooting distance to achieve satisfactory results. However, for users with high-precision shooting needs, this shooting method is not only a waste of time, but may also lead to blurry, distorted, or poorly composed images, affecting shooting efficiency and the quality of shooting results.

[0041] Some embodiments of this disclosure will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted. It should be noted that, without conflict, the embodiments and features in the embodiments of this disclosure can be combined with each other.

[0042] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0043] Figure 1 This is a flowchart illustrating an object distance adjustment method according to some embodiments of the present disclosure, such as... Figure 1 As shown, it includes the following steps.

[0044] Step 101: Obtain the shooting parameters desired by the user.

[0045] The shooting parameters may include: sensor size, effective focal length (EFL), and object height.

[0046] In some examples, shooting parameters are primarily used to help users better control and optimize shooting results. These parameters affect the final photo quality and visual effect in different ways. For example, a larger sensor can usually capture more light information, thus providing better low-light performance and a shallower depth of field (background blur), while the actual focal length determines the extent to which the lens can magnify. For example, a telephoto lens can bring distant objects closer, while a wide-angle lens is suitable for capturing a wider scene. Similarly, the actual height of the object helps to better plan the composition in the photo, ensuring that the proportions of the subject and the environment are harmonious.

[0047] For example, by allowing users to input different shooting parameters (expected shooting values), the calculation method and distance guidance can be flexibly adjusted, solving the problem of needing different shooting parameters in different shooting scenarios. The shooting parameters in this embodiment can be flexibly adjusted according to different shooting needs (such as objects of different sizes or different shooting devices), adapting to a wide range of application scenarios, such as product photography, document scanning, and artistic creation.

[0048] Step 102: Determine the target shooting distance between the object and the shooting lens based on the shooting parameters.

[0049] In some embodiments, desired shooting parameters can be input according to actual conditions, and the target shooting distance between the object and the lens can be calculated according to the imaging principle. By precisely controlling the shooting distance, the clarity and composition effect of the image can be ensured, solving the problems of image blurring, distortion or poor composition caused by improper distance. It provides a professional-grade auxiliary tool for users who need high-precision shooting (such as photographers, engineers, designers, etc.) to help users better complete shooting tasks and improve work efficiency and result quality.

[0050] Step 103: Based on the target shooting distance and the actual distance between the object and the shooting lens, guide the user to adjust the position of the shooting lens.

[0051] For example, the target shooting distance can be displayed on the screen of the shooting device, and the actual distance can be monitored in real time. The user can be guided by voice or screen to adjust the position of the shooting lens so that the distance between the shooting lens and the object is equal to the target shooting distance, so as to achieve the imaging effect desired by the user.

[0052] For example, the combination of software algorithms and hardware sensors enhances the intelligent shooting assistance capabilities of shooting devices (such as mobile phones and cameras), thereby improving the devices' market competitiveness and user satisfaction. Simultaneously, automated calculations and intelligent guidance reduce manual operation and subjective judgment by users, simplifying the user operation process and reducing the hassle of repeatedly adjusting distances, thus improving shooting efficiency and user experience.

[0053] In some embodiments, users only need to input their desired shooting value, and the system can automatically calculate and guide the user to adjust to the optimal shooting distance, thereby improving the automation and intelligence of the shooting process.

[0054] Compared with current related technologies, this embodiment first obtains the user's desired shooting parameters; then, based on the shooting parameters, it determines the target shooting distance between the object and the shooting lens; and finally, based on the target shooting distance and the actual distance between the object and the shooting lens, it guides the user to adjust the position of the shooting lens. By applying the technical solution of this embodiment, the corresponding target shooting distance can be calculated according to the user's desired shooting parameters, and the user can be guided to a position at the target shooting distance from the object. This saves the user's shooting distance adjustment time, allowing the user to more accurately take photos that meet expectations. It effectively avoids problems such as image blurring, distortion, or poor composition caused by improper distance, improving shooting efficiency and user experience.

[0055] To further illustrate, as Figure 1 The specific implementation process of the method shown in this embodiment is provided as follows: Figure 2 The specific method shown includes:

[0056] Step 201: Obtain the shooting parameters desired by the user.

[0057] In some examples, user-input shooting parameters may include: sensor length (assuming the phone is held upright), actual focal length, height of the object being photographed, etc.

[0058] Step 202: Determine the target shooting distance between the object and the shooting lens based on the shooting parameters.

[0059] For example, applying the method of this embodiment can help users better plan their shooting distance, thereby obtaining ideal imaging results. For instance, in portrait photography, photographers can control the degree of background blur by adjusting the shooting distance; in architectural photography, precise control of the shooting distance is required to ensure the correct proportions of the buildings, etc.

[0060] Optionally, the shooting parameters include: sensor size, actual focal length, and object height; correspondingly, step 202 may specifically include: determining the corresponding sensor conversion coefficient based on the sensor size; converting the actual focal length into an equivalent focal length based on the sensor conversion coefficient; and calculating the target shooting distance based on the sensor size, equivalent focal length, and object height.

[0061] For example, a sensor conversion factor can be used to convert the actual focal length of the shooting lens into the equivalent focal length of a 35mm sensor. Equivalent focal length = actual focal length * conversion factor. For instance, the conversion factor for a full-frame sensor is 1, for a 3 / 4-inch sensor it's 1.5, for a 1-inch sensor it's 1.2, and so on. The actual conversion factor can be determined based on the sensor size. Determining the conversion factor based on the sensor size, converting the actual focal length to the equivalent focal length, and calculating the target shooting distance based on these parameters helps to precisely control shooting settings to achieve the desired imaging effect.

[0062] In some examples, such as Figure 3 As shown, H is the object height, Ua is the object distance, Va is the image distance, which is the distance between the shooting lens and the charge-coupled device (CCD) or film, and L is the length of the sensor. The distance Ua can be calculated using the following formula (Formula 1): Ua = f + H * f / L, where f is the EFL value of the optical lens.

[0063]

[0064] Optionally, the method in this embodiment may further include: determining the correspondence between points on the object and points in the field of view according to a preset shooting mode; and calculating the target shooting distance between the object and the shooting lens based on the correspondence.

[0065] For example, such as Figure 3 As shown, a point on an object will form a corresponding point on the sensor through the camera lens. The projection height of the object on the sensor can be estimated by the user to determine how much space the object occupies in the image.

[0066] In some examples, different target shooting distances can be calculated based on different object heights. In these cases, it's recommended that the points corresponding to the head and feet of the object align with the top and bottom edges of the sensor's field of view, respectively. Shooting mode options can be added, such as top-to-bottom mode (the top of the object is at the top of the field of view (fov), and the bottom is at the bottom), half-body mode (the middle of the object is at the bottom of the fov, and the top is in the middle), wide-angle mode, telephoto mode, etc. Calculating the target shooting distance based on the correspondence between points on the object and points in the field of view not only helps users better control composition during photography but also ensures that users obtain the desired shooting results.

[0067] Step 203: Use a distance sensor to measure the actual distance between the object and the camera lens in real time.

[0068] In some examples, distance sensors (such as Time of Flight (ToF) sensors) can be combined to measure the distance between the user and the target object in real time, solving the problem that users cannot accurately judge the current distance during shooting. ToF sensors calculate distance by emitting light pulses and measuring their return time, featuring high accuracy and fast response.

[0069] Step 204: Calculate the distance difference between the actual distance and the target shooting distance.

[0070] For example, by calculating the difference (ΔD) between the actual distance and the target shooting distance, users can understand how far they need to move to reach the desired shooting distance, which helps ensure that the size, proportion, and sharpness of objects in the photo meet expectations.

[0071] Step 205: Based on the distance difference, guide the user to adjust the position of the shooting lens.

[0072] In some examples, by incorporating a distance sensor, the distance between the user and the target object can be measured in real time, and the user can be guided to adjust the shooting distance to the target through screen display and prompts, which greatly reduces shooting errors and ensures the clarity and quality of the captured images.

[0073] Optionally, step 205 may specifically include: if the actual distance is greater than the target shooting distance, then guiding the user to move the shooting lens a corresponding distance closer to the object; if the actual distance is less than the target shooting distance, then guiding the user to move the shooting lens a corresponding distance away from the object.

[0074] For example, displaying the calculated target shooting distance on the screen can help users reach the corresponding location more accurately for shooting. It can also be combined with a ToF sensor to measure the current distance and then guide the user to gradually approach the calculated target shooting distance, allowing the user to accurately capture the desired image.

[0075] For example, if the actual distance is greater than the target shooting distance (ΔD > 0), the application can prompt the user via screen display or voice: "Please move the lens towards the object by approximately ΔD millimeters." If the actual distance is less than the target shooting distance (ΔD < 0), the application can prompt the user via screen display or voice: "Please move the lens away from the object by approximately |ΔD| millimeters." As the user gradually adjusts the position according to the prompts, the application remeasures the current distance and updates the prompt information after each adjustment until the target shooting distance is reached. By combining the calculated target shooting distance with the real-time measurement results from the ToF sensor, the application can effectively guide the user to precisely adjust the lens position, thereby achieving the desired shooting effect. This method not only improves shooting accuracy but also enhances the user experience, making the photography process more intelligent and convenient.

[0076] Optionally, the method in this embodiment may further include: guiding the user to move the camera lens through screen display and / or prompt sound, so that the distance between the object and the camera lens is equal to the target shooting distance.

[0077] For example, by displaying information on the screen of the shooting device and providing prompts, the system dynamically guides the user to adjust to the optimal shooting distance, solving the problem that users find it difficult to maintain the optimal distance during shooting. This includes: displaying the current distance and the target distance in real time; providing visual or auditory feedback; and guiding the user step by step to adjust the shooting lens to the optimal position through voice or image, so that the distance between the object and the shooting lens is equal to the target shooting distance, ensuring that the captured photos meet the desired effect.

[0078] Compared with current related technologies, this embodiment can calculate the corresponding target shooting distance based on the user's desired shooting parameters and guide the user to a position at the target shooting distance from the object. This saves the user's shooting distance adjustment time, allowing the user to take photos that meet expectations more accurately. It can effectively avoid problems such as image blurring, distortion, or poor composition caused by improper distance, thus improving shooting efficiency and user experience.
