All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is to be understood that the terminology used in the embodiments of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
The embodiment of the invention provides a shooting method and a shooting device, which can be used for shooting a clear picture even if a shot object and a shooting terminal are in a close distance. The following describes a photographing method and apparatus provided by an embodiment of the present invention with reference to fig. 1 to 4.
Referring to fig. 1, it is a schematic flow chart of a first embodiment of the shooting method provided by the present invention, and the method includes:
step S101: detecting an object distance between a shot object and a terminal;
specifically, the terminal may detect an object distance between the photographing object and the terminal (the object distance is a distance between the object and the mirror (or an optical center of the lens)) according to a sensor, wherein the sensor includes but is not limited to: a distance sensor. The terminal may include a personal computer, a smart phone (such as an Android phone, an iOS phone, etc.), a tablet computer, a palm computer, a Mobile Internet device (MID, Mobile Internet Devices), or a wearable smart device, and other Internet Devices. The sensor may be embedded in the terminal, that is, the sensor is embedded in the terminal, or the sensor may be independent from the terminal, that is, the sensor and the terminal are separated from each other, the sensor may always detect an object distance between the photographic object and the terminal, may also detect the object distance between the photographic object and the terminal at regular time, or may start to detect the object distance between the photographic object and the terminal after receiving a start instruction of a terminal user, which is not specifically limited in the embodiment of the present invention.
Step S103: if the object distance between the shot object and the terminal is judged to be larger than a first preset threshold value and smaller than a second preset threshold value, the shooting attribute of the shot object is modified according to the object distance and a preset rule, wherein the preset rule is used for indicating a modification mode for modifying the shooting attribute of the shot object;
specifically, the terminal can judge whether the object distance is greater than a first preset threshold and smaller than a second preset threshold according to the object distance between the shooting object and the terminal detected by the sensor, and if the object distance is greater than the first preset threshold and smaller than the second preset threshold, it is proved that the shooting object and the terminal are in a close-range state, the terminal needs to adjust the current shooting attribute of the shooting object according to a preset rule so as to shoot a clear picture. The first preset threshold may be a distance threshold of a macro mode preset by a terminal user, or may be a distance threshold of a macro mode default set in a terminal camera application system program, for example, according to a motor limit of a terminal camera, an object distance of 7cm is generally set as the distance threshold of the macro mode, when an object distance between a photographed object and a terminal is smaller than or equal to the first preset threshold, it is proved that the photographed object is within a macro range, and the terminal is difficult to focus the photographed object within the macro range, so that the terminal is required to prompt the user to increase the object distance between the photographed object and the terminal. Wherein the shooting attributes may include, but are not limited to: zooming times and shooting sampling number, when the object distance is in a close range outside a micro range, the shooting property of the shot object needs to be modified according to a preset rule, namely the zooming times and the shooting sampling number need to be increased, so that the terminal can shoot clear photos. The preset rule may be a shooting attribute rule set by the user himself or a shooting attribute rule set by default for a camera application system program of the terminal. When the object distance exceeds a second preset threshold, the fact that the distance between the shot object and the terminal exits the short-distance range is proved, namely the terminal can shoot normally, and zooming times and shooting sampling number do not need to be increased.
Further, see table 1, which is a corresponding relationship between the object distance and the preset rule in the embodiment of the present invention, wherein the first preset threshold is 7cm, and the second preset threshold is 15 cm.
TABLE 1
| Object distance | Multiple of zoom | Number of samples taken |
| 7cm | 1 | 1 |
| 8cm | 2 | 2 |
| 9cm | 3 | 4 |
| 10cm | 4 | 6 |
| 11cm | 5 | 8 |
| 12cm | 4 | 6 |
| 13cm | 3 | 4 |
| 14cm | 2 | 2 |
| 15cm | 1 | 1 |
As can be seen from table 1, when the object distance between the photographed object and the terminal is less than or equal to the first preset threshold value of 7cm, the zoom multiple and the number of photographed samples are normal values, and when the object distance between the photographed object and the terminal is greater than the first preset threshold value of 7cm and less than the second preset threshold value of 15cm, the zoom multiple and the number of photographed samples change according to the preset rule, and the change trend is: and when the object distance between the shot object and the terminal is larger than a second preset threshold value of 15cm, the zoom multiple and the number of shot samples are restored to normal values again. For optical zoom, the larger the optical zoom factor, the farther the scene can be photographed. After the optical zooming can support the imaging of an image main body, the resolution and the image quality are not changed, and the image is relatively clear; for digital zooming, the larger the digital zooming multiple is, the larger the picture is, through digital zooming, the shot scenery is enlarged, but the definition of the scenery is reduced to a certain extent, but the details are not clearer, and in specific application, a user can set a preset rule, so that a clear picture is shot.
Step S105: and shooting the shooting object with the shooting attribute modified.
Specifically, after the terminal modifies the shooting attribute of the shooting object according to the preset rule according to the object distance between the shooting object and the terminal, shooting the shooting object is started.
In the embodiment of the invention, the terminal judges whether the object distance is in a short-distance range or not according to the detected object distance between the shooting object and the terminal, and when the shooting object is in the short-distance range with the terminal, the shooting attribute of the shooting object needs to be changed, so that a clear picture is shot.
Further, referring to fig. 2, it is a schematic flow chart of a second embodiment of the shooting method provided by the present invention, and the method includes:
step S201: detecting an object distance between a shot object and a terminal;
specifically, the terminal may detect an object distance between the photographing object and the terminal (the object distance is a distance between the object and the mirror (or an optical center of the lens)) according to a sensor, wherein the sensor includes but is not limited to: a distance sensor. The terminal may include a personal computer, a smart phone (such as an Android phone, an iOS phone, etc.), a tablet computer, a palm computer, a Mobile Internet device (MID, Mobile Internet Devices), or a wearable smart device, and other Internet Devices. The sensor may be embedded in the terminal, that is, the sensor is embedded in the terminal, or the sensor may be independent from the terminal, that is, the sensor and the terminal are separated from each other, the sensor may always detect an object distance between the photographic object and the terminal, may also detect the object distance between the photographic object and the terminal at regular time, or may start to detect the object distance between the photographic object and the terminal after receiving a start instruction of a terminal user, which is not specifically limited in the embodiment of the present invention.
Step S203: judging whether the object distance is smaller than or equal to a first preset threshold value;
specifically, when the terminal detects an object distance between a shooting object and the terminal according to a sensor, it is determined whether the object distance is smaller than or equal to a first preset threshold, where the first preset threshold may be a distance threshold in a macro mode preset by a terminal user, or may be a distance threshold in a macro mode default set in a terminal camera application system program, for example, according to a motor limit of a terminal camera, the object distance of 7cm is generally set as the distance threshold in the macro mode, when it is determined that the object distance is smaller than or equal to the first preset threshold, step S205 is performed, and when it is determined that the object distance is greater than the first preset threshold, step S207 is performed.
Step S205: providing preset prompt information, wherein the preset prompt information is used for prompting that the distance between the shot object and the terminal is increased;
specifically, when the object distance between the shooting object and the terminal is judged to be smaller than or equal to a first preset threshold value, the shooting object is proved to be in a micro distance range, the terminal is difficult to focus the shooting object in the micro distance range, therefore, the terminal is required to prompt a user to increase the object distance between the shooting object and the terminal, the terminal provides preset prompt information for the user to prompt the user to increase the distance between the shooting object and the terminal, and the phenomenon that the shooting is unclear due to the fact that the distance between the shooting object and the terminal is too small is avoided. The prompting method may include, but is not limited to: and popping up a prompt box.
Step S207: judging whether the object distance is smaller than a second preset threshold value or not;
specifically, when the object distance between the shooting object and the terminal is judged to be larger than a first preset threshold, whether the object distance is smaller than a second preset threshold is judged, when the object distance is smaller than the second preset threshold, it is proved that a close range exists between the shooting object and the terminal, the shooting attribute of the shooting object needs to be processed to shoot a clear picture, and when the object distance is larger than the second preset threshold, it is proved that the shooting object and the terminal are not located in the close range, the terminal can normally shoot the shooting object. When the object distance is smaller than a second preset threshold, the process proceeds to step S209, and when the object distance is larger than the second preset threshold, the process proceeds to step S211.
Step S209: modifying the shooting attribute of the shot object according to the object distance and a preset rule, wherein the preset rule is used for indicating a modification mode for modifying the shooting attribute of the shot object, and the shooting attribute comprises: zooming times and shooting sampling number;
specifically, when the object distance between the photographic object and the terminal is greater than a first preset threshold and smaller than a second preset threshold, the photographic attribute of the photographic object needs to be modified according to a preset rule, where the photographic attribute may include but is not limited to: the zoom factor and the number of shot samples are required to be increased so that the terminal can take clear pictures. The preset rule may be a shooting attribute rule set by the user himself or a shooting attribute rule set by default for a camera application system program of the terminal. After this step is performed, the flow proceeds to step S213.
Further, when the object distance between the shot object and the terminal is larger than a first preset threshold and smaller than a second preset threshold, the terminal modifies the zoom multiple corresponding to the shot object and the number of shot samples corresponding to the shot object according to the object distance and a preset rule.
Step S211: setting the shooting attribute of the shot object as a preset shooting attribute value;
specifically, when the object distance between the photographed object and the terminal is greater than or equal to a second preset threshold, it indicates that the photographed object exits from the close-range state, and the terminal may restore the photographing attribute of the photographed object to a normal value, that is, restore the zoom multiple and the number of photographing samples of the photographed object to normal values, thereby performing normal photographing.
Further, when the object distance between the shot object and the terminal is greater than or equal to a second preset threshold value, it indicates that the shot object exits the close-range state, the terminal sets the zoom multiple corresponding to the shot object as a zoom multiple preset value, and sets the number of shot samples corresponding to the shot object as a shot sample number preset value.
Step S213: and shooting the shooting object with the shooting attribute modified.
Specifically, after the terminal modifies the shooting attribute of the shooting object according to the preset rule according to the object distance between the shooting object and the terminal, shooting the shooting object is started.
In the embodiment of the invention, the terminal judges whether the object distance is in a short-distance range or not according to the detected object distance between the shooting object and the terminal, when the shooting object and the terminal are in a micro-distance range, the terminal prompts a user to increase the object distance between the shooting object and the terminal, when the shooting object and the terminal are in the short-distance range, the terminal modifies the zoom multiple and the shooting sampling number of the shooting object according to a preset rule so as to shoot clear photos, and when the shooting object and the terminal exit from the short-distance range, the terminal restores the shooting attribute of the shooting object to a normal state value so as to finish normal shooting.

The terminal may include a personal computer, a smart phone (such as an Android phone, an iOS phone, etc.), a tablet computer, a palm computer, a Mobile Internet device (MID, Mobile Internet Devices), or a wearable smart device, and other Internet Devices.

specifically, the terminal may determine whether the object distance is greater than a first preset threshold and smaller than a second preset threshold according to the object distance between the shooting object and the terminal detected by the sensor, and if the object distance is greater than the first preset threshold and smaller than the second preset threshold, that is, it is proved that the shooting object and the terminal are in a close-range state, the modification unit 303 needs to adjust the current shooting attribute of the shooting object according to a preset rule, so as to shoot a clear picture. The first preset threshold may be a distance threshold of a macro mode preset by a terminal user, or may be a distance threshold of a macro mode default set in a terminal camera application system program, for example, according to a motor limit of a terminal camera, an object distance of 7cm is generally set as the distance threshold of the macro mode, when an object distance between a photographed object and a terminal is smaller than or equal to the first preset threshold, it is proved that the photographed object is within a macro range, and the terminal is difficult to focus the photographed object within the macro range, so that the terminal is required to prompt the user to increase the object distance between the photographed object and the terminal. Wherein the shooting attributes may include, but are not limited to: zooming times and shooting sampling number, when the object distance is in a close range outside a micro range, the shooting property of the shot object needs to be modified according to a preset rule, namely the zooming times and the shooting sampling number need to be increased, so that the terminal can shoot clear photos. The preset rule may be a shooting attribute rule set by the user himself or a shooting attribute rule set by default for a camera application system program of the terminal.
