Referring to fig. 1, a flowchart illustrating steps of a photographing method according to an embodiment of the present invention is shown, where the method may be applied to a mobile terminal, which may include, but is not limited to, a mobile phone, a tablet computer, a laptop computer, a palm computer, a vehicle-mounted terminal, a wearable device, a pedometer, and the like.
The mobile terminal may have a camera with an adjustable aperture, which is a device for controlling the amount of light that passes through the lens and into a light sensing surface in the camera.
Specifically, the embodiment of the present invention may include the following steps:
in the embodiment of the invention, a user can start the camera of the mobile terminal, enter the preview shooting interface and then adopt the camera to acquire the preview image data.
Wherein the preview image data may comprise structured light encoded information.
As an example, the structured light may be Infrared (IR) light.
In practice, the mobile terminal may have an RGB sensor, a structured light projector, and a structured light sensor, and when the mobile terminal uses the RGB sensor to collect an image, the structured light projector is also used to project a light spot, a light slit, a grating, a grid or stripes onto an object to be measured, and then the structured light sensor is used to collect structured light encoding information of the object to be measured, such as an encoding pattern modulated by the surface of the object to be measured.
In a preferred example, the structured light sensor may be disposed in an RGB sensor of the camera, for example, a half of each G sensing unit is replaced with the structured light sensor, and a part of any color sensing unit is replaced with the structured light sensor, so that the RGB sensor may receive the structured light reflected by the object to be measured, and the opening of the structured light sensor may be reduced on the mobile terminal, thereby improving the aesthetic feeling of the appearance.
after the preview image data is obtained, the mobile terminal can determine the depth of field information of the preview image data according to the structured light coding information in the preview image data, and then determine the aperture adjustment parameter of the camera according to the depth of field information so as to adjust the aperture of the camera.
In a preferred embodiment of the present invention, step 102 may comprise the following sub-steps:
a substep 11 of detecting a photographic subject from the preview image data;
in the embodiment of the invention, the mobile terminal can detect the preview image data and determine one or more shooting subjects from the preview image data.
Specifically, the sub-step 11 may include the following sub-steps:
detecting at least two touch operations of a user on the preview image data; determining a target area selected by the at least two touch operations; and detecting a photographic subject in the target area.
In the embodiment of the invention, the mobile terminal can display the preview image data on the shooting preview interface, when the touch operation of the user on the preview image data is detected, for example, 2 points in the preview image data are touched and selected, the mobile terminal determines the target area selected by the touch operation, and further performs image detection on the target area to identify the outline of the shooting subject in the target area.
A substep 12, determining depth information of the shooting subject according to the structured light coding information;
after the shooting subject is determined, the mobile terminal can determine a pixel point corresponding to the shooting subject from the preview image data, further acquire the structured light coding information of the pixel point, decode the structured light coding information, and determine the depth-of-field information of the shooting subject according to the decoded structured light coding information.
Specifically, the mobile terminal may encode the structured light in a spatial encoding manner, such as a DeBruijn sequence encoding, and/or may encode the structured light in a time encoding manner, such as a binary encoding and a gray encoding, where the spatial encoding manner may only project a single preset structured light encoding information, such as a single-frame structured light encoding pattern, and the time encoding manner may project a plurality of different preset structured light encoding information, such as a plurality of different frames of structured light encoding patterns.
For the spatial coding mode, the mobile terminal can obtain the matching relation between the collected structured light coding information and the preset structured light coding information by comparing the collected structured light coding information and the preset structured light coding information after decoding the collected structured light coding information, and calculate the depth of field information of the shooting subject by combining the triangular ranging principle.
According to the time coding mode, the structured light sensor can collect a plurality of structured light coded information modulated by the surface of the second moving object, the obtained plurality of structured light coded information are decoded, and the depth of field information of the shooting main body is obtained through calculation by combining a triangular distance measurement principle.
And a substep 13 of obtaining aperture adjustment parameters corresponding to the depth of field information.
After the depth of field information of the shooting subject is determined, the mobile terminal can acquire aperture adjustment parameters corresponding to the depth of field information so as to adjust the aperture of the camera and ensure the definition of the shooting subject in the image.
Specifically, the substep 13 may comprise the substeps of:
determining a depth of field deviation value of the depth of field information and preset depth of field information; matching the depth of field deviation value in a preset database to obtain a corresponding aperture adjustment parameter;
the preset database can store the corresponding relation between a plurality of depth of field deviation values and aperture adjustment parameters.
In the embodiment of the invention, the preset depth-of-field information exists, and when the depth-of-field information of the shooting subject is the preset depth-of-field information, the definition of the shooting subject in the image is the best.
The depth of field deviation value is obtained by calculating the difference value between the current depth of field information and the preset depth of field information of the shooting main body, then matching is carried out in a preset database, and the corresponding aperture adjustment parameter is found, so that the automatic adjustment of the aperture based on the depth of field information is realized, and the definition of the shooting main body in the image is ensured.
103, adjusting the aperture F value of the camera according to the aperture adjustment parameters;
after the aperture adjustment parameters are obtained, the mobile terminal can adjust the aperture F value of the camera according to the aperture adjustment parameters, so that the definition of the shooting main body in the image is ensured.
The aperture F value is a relative value obtained by the focal length of the lens and the light passing diameter of the lens, the aperture is increased when the aperture F value is reduced, and the aperture is reduced when the aperture F value is increased.
In a preferred embodiment of the present invention, the aperture adjustment parameter may include an F-number adjustment amplitude, and step 103 may include the following sub-steps:
substep 21, obtaining a current aperture F value of the camera;
in the embodiment of the invention, the mobile terminal can acquire the current aperture F value set by the camera.
A substep 22, when the depth of field information is larger than the preset depth of field information, reducing the current F value of the aperture according to the F value adjustment range;
the aperture is the most important factor for determining the depth of field, and is small (large F value), deep, large (small F value), and shallow.
When the detected depth of field information is larger than the preset depth of field information, the mobile terminal can reduce the current F value of the aperture according to the F value adjustment amplitude so as to increase the aperture of the camera and further reduce the depth of field.
And a substep 23, increasing the F value of the current aperture according to the F value adjustment range when the depth of field information is smaller than the preset depth of field information.
When the detected depth of field information is smaller than the preset depth of field information, the mobile terminal can increase the current F value of the aperture according to the F value adjustment range so as to reduce the aperture of the camera and further increase the depth of field.
And step 104, shooting by using the camera with the adjusted aperture F value to obtain a target image.
After the aperture is adjusted, the mobile terminal can shoot by adopting the camera after the aperture F value is adjusted, and when a shooting instruction input by a user is received, a target image is shot.
In the embodiment of the invention, the aperture adjustment parameters of the camera are determined by acquiring the preview image data acquired by the camera according to the structured light coding information in the preview image data, then the aperture F value of the camera is adjusted according to the aperture adjustment parameters, and the camera after adjusting the aperture F value is adopted to shoot to obtain the target image, so that the automatic adjustment of the aperture based on the structured light is realized, the accuracy of aperture adjustment is ensured, and the effect of picture shooting is improved.
Referring to fig. 2, a flowchart illustrating steps of a shooting method according to an embodiment of the present invention is shown, where the method may be applied to a mobile terminal, where the mobile terminal has a camera, and specifically includes the following steps:
in the embodiment of the invention, a user can start the camera of the mobile terminal, enter the preview shooting interface and then adopt the camera to acquire the reference preview image data.
After obtaining the reference preview image, the mobile terminal may detect whether the reference preview image data meets a preset condition, and if so, enter step 203, and if not, adjust the focal length of the camera to ensure that the complete shot object is displayed in the preview image data.
For example, when a camera of the mobile terminal is used for scanning the two-dimensional code, and when the two-dimensional code in the shooting preview interface is incomplete and cannot be identified, the mobile terminal can automatically adjust the focal length of the camera so as to completely display the two-dimensional code in the shooting preview interface.
wherein the preview image data may comprise structured light encoded information.
After the focal length is adjusted, the mobile terminal can adopt the camera to acquire preview image data.
after the preview image data is obtained, the mobile terminal can determine the depth of field information of the preview image data according to the structured light coding information in the preview image data, and then determine the aperture adjustment parameter of the camera according to the depth of field information so as to adjust the aperture of the camera.
after the aperture adjustment parameters are obtained, the mobile terminal can adjust the aperture F value of the camera according to the aperture adjustment parameters, so that the definition of the shooting main body in the image is ensured.
after the aperture is adjusted, the mobile terminal can shoot by adopting the camera after the aperture F value is adjusted, and when a shooting instruction input by a user is received, a target image is shot.
And step 207, performing two-dimensional code scanning on the target image.
When the two-dimensional code exists in the target image, the mobile terminal can scan the two-dimensional code of the target image so as to identify the two-dimensional code in the target image.
In the embodiment of the invention, the aperture adjustment parameters of the camera are determined by acquiring the preview image data acquired by the camera according to the structured light coding information in the preview image data, then the aperture F value of the camera is adjusted according to the aperture adjustment parameters, and the camera after adjusting the aperture F value is adopted to shoot to obtain the target image, so that the automatic adjustment of the aperture based on the structured light is realized, the accuracy of aperture adjustment is ensured, and the effect of picture shooting is improved.
