Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In the following description, suffixes such as "module", "part" or "unit" for representing elements are used only for facilitating the description of the present invention, and have no particular meaning in themselves. Thus, "module," "component," or "unit" may be used in combination.
Fig. 1 is a first flowchart of an image capturing control method according to an embodiment of the present invention, where, as shown in fig. 1, the method may include:
step S101: it is detected whether a raster needs to be displayed in the current shooting scene.
Step S102: when the display of the grating is detected, the grating is displayed on the shooting interface by adjusting an electrochromic grating layer built in the shooting module.
The photographing control method of the embodiment eliminates glare or harmful light reflection in the photographing process by utilizing the electrochromic grating layer built in the photographing module so as to achieve the optimal photographing effect and optimize the photographing quality. In addition, because the electrochromic grating layer is arranged in the camera module, but not externally connected with the electrochromic grating layer or the polarizer, the problems of carrying, repeated installation and disassembly of an external accessory in the actual use process are avoided, and the user experience is improved.
Fig. 2 is a second flowchart of an image capturing control method according to an embodiment of the present invention, and as shown in fig. 2, compared to the embodiment of fig. 1, after performing step S101 and step S102, the method may further include:
step S103: and when the grating is displayed, adjusting the exposure of the shooting interface.
By utilizing the polarization principle of light, glare or harmful light reflection in the shooting process can be eliminated, and the definition and expressive force of the shot images are improved. However, the display grating can reduce the incident light entering the lens, and the underexposure problem occurs, so that the embodiment eliminates the underexposure problem caused by the reduction of the incident light source by adjusting the exposure amount after displaying the grating.
Electrochromic materials refer to stable and reversible color changes of optical properties such as reflectivity, transmissivity, absorptivity and the like of the materials under the action of an external electric field, and the materials are expressed as reversible changes of color and transparency in appearance. In the prior art, electrochromic materials are generally applied to a camera filter, one or more electrochromic material layers are added on a camera module, and the transparency of the electrochromic material layers is adjusted by adjusting electromagnetism, so that the purposes of adjusting the color temperature of a photo according to the environment or adjusting the color of the filter according to the selection of a user and enriching the shooting effect are achieved. From the shooting effect of the prior art, the shooting effect of the user can only be enriched, but the user cannot be helped to solve the problem of harmful light treatment in the shooting scene, and the effects can also realize similar effects through post adjustment of photos; meanwhile, the utilization mode of the color-changing material is single, the purpose of free color mixing is realized only by superposition color changing, and the adjustment dimension of the material only comprises the adjustment of transparency. In this embodiment, the electrochromic material characteristic is added to the manufacture of the polarizer, particularly to the manufacture of the linear polarizer, and specifically, the electrochromic grating capable of being used as the polarizer is manufactured by utilizing the electrochromic material characteristic, so that the purpose of arranging the polarizer in a camera module, such as a camera module of a mobile terminal such as a mobile phone, is achieved, the problem of low shooting quality caused by glare or harmful reflection is solved, the shooting and shooting quality is improved, and the user experience is improved. Meanwhile, in order to solve the problem of underexposure, the exposure of a photographing interface is automatically adjusted during raster display, so that the photographing effect is further ensured.
Further, the step S101 may include: judging whether an intelligent shooting mode is started or not, detecting an image acquired by the camera module when judging that the intelligent shooting mode is started, and determining that a grating needs to be displayed in a current shooting scene if the image content of the grating needs to be displayed in the image is detected; and when judging that the intelligent shooting mode is not started, detecting whether the polarization shooting mode (such as a landscape shooting mode) is started manually, and if the polarization shooting mode is detected to be started manually, determining that a grating needs to be displayed in the current shooting scene. That is, in this embodiment, after the polarization grating (i.e., the electrochromic grating or the polarizer) is fabricated by using the electrochromic material and is built in the image capturing module, whether the electrochromic grating is displayed or not may be automatically controlled according to content identification or specific scene, specifically, in the case that the intelligent image capturing mode is started, the content of the image acquired by the image capturing module may be identified, if the landscape element is identified, the display of the grating is controlled, in the case that the intelligent image capturing mode is not started, that is, the current manual image capturing mode is started, and at this time, if the polarization image capturing mode is started by the user, the display of the grating is controlled.
Further, the step S102 may include: and adjusting the electric field parameters according to the corresponding relation between the preset transparency and the electric field parameters, so that the electrochromic grating layer in the camera module displays the grating according to the corresponding transparency. In addition, the grating structure of the electrochromic grating layer can be used for controlling the light passing in a single direction, so that glare or harmful reflection in the shooting process is eliminated.
Further, the step S103 may include: when the grating display is carried out, the exposure adjustment quantity corresponding to the transparency of the electrochromic grating layer in the camera module is determined according to the corresponding relation between the preset transparency and the exposure adjustment quantity, and then the exposure quantity is adjusted according to the exposure adjustment quantity corresponding to the transparency of the electrochromic grating layer in the camera module and the initial exposure parameter. Wherein, the initial exposure parameter is obtained and recorded by performing initial photometry before the step S102.
After step S103, if it is detected that the user presses the photographing button, which indicates that the user is satisfied with the photographing effect of the current preview, the currently photographed image may be stored.
In the actual shooting process, the user may not be satisfied with the shooting effect of the current preview, and for this reason, the present embodiment provides an adjustment bar on the interactive interface, and after step S103, the user may autonomously adjust the angle and transparency of the grating. Specifically, an angle adjusting bar and a transparency adjusting bar are provided on an interactive interface, and the angle of the electrochromic grating in the camera module can be set by using the angle adjusting bar in the interactive interface; a transparency adjustment bar may also be provided on the interactive interface, with which the transparency of the electrochromic grating in the camera module may be set. In addition, besides setting and adjusting the angular transparency of the grating by adjusting the bar, other shooting parameters, such as an exposure adjustment amount, may be set on the interactive interface, and alternatively, the exposure adjustment amount corresponding to the set transparency may be determined according to the preset correspondence between the transparency and the exposure adjustment amount. After the set angle, transparency and corresponding exposure adjustment amount are obtained, the angle and transparency of the grating and the exposure of the shooting interface can be controlled, so that an image satisfactory to a user is obtained.
The electrochromic grating manufactured in this embodiment is used as a linear polarizer, so when shooting involves focusing and photometry operations, an electric field hiding grating layer needs to be automatically adjusted before focusing and photometry, so that focusing and photometry effectiveness is ensured, that is, re-photometry is needed under the condition of hiding the electrochromic grating, so as to record re-exposure parameters. Then controlling the angle and transparency of the grating and the exposure of a shooting interface, specifically, determining the structural parameter of the shooting module corresponding to the angle of the electrochromic grating set on the interactive interface according to the corresponding relation between the preset angle and the structural parameter of the shooting module, thereby adjusting the grating angle of the electrochromic grating layer by adjusting the structural parameter of the shooting module where the electrochromic grating is positioned, realizing that a user adjusts the angle of the grating through the interactive interface and selecting the incident light angle; according to the corresponding relation between the preset transparency and the electric field parameters, the electric field parameters corresponding to the transparency of the electrochromic grating set on the interactive interface are determined, so that the grating transparency of the electrochromic grating layer is adjusted by adjusting the electric field parameters, the transparency of the grating is adjusted by a user through the interactive interface, and the visibility of the grating is changed; and when the grating is displayed, adjusting the exposure according to the re-exposure parameter and the exposure adjustment corresponding to the set transparency to obtain the adjusted exposure, so as to perform exposure processing on the image of the shooting interface according to the adjusted exposure.
The polarizer comprises a linear polarizer and a circular polarizer, and the shooting effects of the two lenses are consistent. Among them, the linear polarizer affects the accuracy of the photometry system on the automatic camera, and thus is more applied to the conventional manual camera. The circular polarizer is formed by superposing a quarter wave plate on the basis of the linear polarizer, and after linear polarized light is converted into circular polarized light, the problem of light measurement is solved, but the composition and thickness of the lens are actually increased. Therefore, under the scene that the precision requirement on a light measuring system is high, but the thickness requirement on an electrochromic camera module is not high, a quarter wave plate can be added between an electrochromic grating of a single electrochromic camera module and a conventional lens assembly in the camera module, so that in the actual shooting process, after a user adjusts shooting parameters such as grating angle, transparency and the like, the light measuring process can be omitted, the angle, the transparency of the grating and the exposure of a shooting interface can be directly controlled, namely, under the condition that the quarter wave plate is arranged between the electrochromic grating and the lens assembly of the camera module where the electrochromic grating is positioned, the grating angle and the transparency of the electrochromic grating layer are adjusted according to the set angle and transparency of the electrochromic grating so as to display the grating; and when the grating is displayed, adjusting the exposure according to the exposure adjustment corresponding to the set transparency.
In addition, the embodiment adjusts the electric field parameters according to the content identification of the acquired image and the user operation instruction, further changes the transparency of the electrochromic grating layer, controls the light passing in a single direction through the grating structure, and adjusts the exposure simultaneously, thereby solving the problems of low shooting quality and insufficient exposure caused by glare or harmful reflection in the shooting process and improving the user experience.
The image capturing control process of the capturing process is described in detail below with reference to fig. 3.
Before the shooting process starts, the parameters of the equipment need to be preset, specifically, before the actual shooting, the parameters of the following 6 parts of software and hardware of the equipment are preset:
A. The corresponding relation between the display transparency (abbreviated as transparency) of the electrochromic grating layer and the practical parameter (abbreviated as electric field parameter) of the applied electric field is preset, so that the display transparency of the electrochromic grating (abbreviated as grating) can be adjusted by adjusting the electric field parameter in the shooting process.
B. The corresponding relation between the angle of the electrochromic grating layer and the structural parameters of the camera module is preset, so that the angle of the electrochromic grating can be changed by adjusting the camera module structural member of the camera module where the electrochromic grating layer is located.
C. Presetting a corresponding relation between an angle adjusting bar of a user interface (or called an interactive interface) and an angle of an electrochromic grating; the corresponding relation between the grating transparency adjusting bar (transparency adjusting bar for short) of the user interface and the transparency of the electrochromic grating is preset.
D. After the display of the grating, a certain exposure degree needs to be increased to maintain the brightness of the shot content, so that the exposure adjustment amount of the camera module is required to be preset after the electrochromic grating is displayed by a user.
E. The initial transparency and angle of the electrochromic grating are preset, and the initial transparency of the grating can be set to 0%, i.e. the grating is not displayed.
F. If the shooting function of the terminal equipment supports intelligent object identification or intelligent mode switching, presetting shooting modes or displaying a grating by default after identifying elements; the rest mode defaults to not displaying the raster. Because the polarization is mainly used for scenery shooting to solve the problems of glare and harmful reflection, the electric field display grating is automatically adjusted when the scenery shooting mode is preset or the image glare is identified under the general condition.
After the device parameters are preset, the specific implementation steps of the user shooting may be as shown in fig. 3, as follows:
step C201: detecting that the camera module is started, and a user opens a shooting application.
The embodiment needs to be carried out under shooting operation of a user, and the starting state of the shooting module is detected firstly, so that the normal acquisition of image information is ensured; and, the user has opened a specific photographing or photographing application, and can preview the photographing effect in the interface.
Judgment C202.1: the camera module acquires an image and detects the content of a preset grating layer to be displayed.
When the intelligent shooting mode is in, that is, the intelligent object identification is started or the intelligent mode is switched, if the content of the grating which is required to be displayed and accords with the preset information is identified, the step S201 is executed, otherwise, the state that the grating is not displayed (that is, the transparent state of the grating) is maintained, and the common shooting flow is executed.
Judgment C202.2: it is detected that the user manually turns on the polarized shooting mode.
When the intelligent shooting mode is not started or supported, the user uses the manual shooting mode to shoot, whether the user manually starts the polarized shooting mode needs to be detected, if the polarized shooting mode is started, step S201 is executed, otherwise, the grating is kept in a non-display state (namely, the grating transparent state), and a common shooting flow is carried out.
Step S201: before the electrochromic grating is displayed, initial photometry and focusing are performed.
Because the linear polarization grating has influence on the light measurement and focusing operation in the digital shooting process, the initial light measurement and focusing operation is performed in the transparent state of the grating before the electrochromic grating is displayed, and the exposure parameters and focusing parameters in the current shooting state are recorded.
Step S202: and adjusting the electric field parameters according to the preset, so that the electrochromic grating is displayed.
After step S201 is completed, the electric field parameters are adjusted according to the corresponding relation between the preset electric field parameters and the transparency parameters of the electrochromic grating, so that the grating is displayed, and the control of the incident light is realized.
Step S203: after the grating is displayed, the shooting exposure is adjusted according to the preset.
After the grating is displayed, since the incident light quantity is reduced, the shot exposure needs to be adjusted, and the exposure parameters obtained in step S201 are added with the exposure adjustment quantity in parameter presetting, so that the brightness of the shot content is still suitable after the grating is displayed.
Step S204: and acquiring user interface adjustment parameters, and adjusting parameters of the actual electrochromic grating layer and other shooting parameters based on the preset parameters.
After the electrochromic grating is displayed, a user also needs to adjust the angle and the transparency of the grating by using an adjusting bar in the interactive interface according to the condition of the actual shooting scene, and proper parameters are selected so that the shot photo has the best effect. Meanwhile, the user can adjust other conventional parameters such as shooting focusing objects, shooting exposure, color temperature and the like.
Step S205: after the user adjusts the parameters, the electrochromic grating is hidden for secondary photometry and focusing.
When the user completes parameter adjustment, re-metering and focusing can be performed before shooting. In order to ensure the effectiveness of photometry and focusing, the grating angle and transparency parameters set by the current user are recorded before photometry and focusing, and then the electric field parameters are changed in the photometry and focusing process to set the transparency of the electrochromic grating to be completely transparent.
Step S206: based on the grating angle set by the user, the electric field and the structural parameters of the camera module are adjusted, so that the electrochromic grating is displayed.
After the re-photometry and focusing are completed, the electric field and the structural parameters of the camera component are continuously adjusted, and the electrochromic grating is adjusted to the parameters which are recorded in the step S205 and adjusted by the user, including the angle and the transparency.
Step C103: it is detected whether the user presses the photographing button, if so, step S207 is performed, otherwise, the judgment of C202.1 or C202.2 is repeated according to the situation.
In the whole shooting process, whether a user presses a shooting button in the interactive interface needs to be detected, if the user presses the shooting button, the shooting effect image or image previewed by the current interactive interface needs to be shot by the user is indicated, and then step S207 is executed; if the operation of pressing the shooting button by the user is not detected, the user is indicated to continue adjusting shooting content, and the judgment of C202.1 or C202.2 is repeated according to the situation.
Step S207: and storing the currently shot image information or image information.
After clicking the shooting button, the user stores the image information or the image information acquired by the current shooting module into the storage module, so as to support the user to view and preview shooting contents or perform other editing operations.
According to the invention, the electrochromic material is used for manufacturing the grating layer and is arranged in the camera module, when a user shoots a photo or a video, the electric field parameters can be adjusted according to the content identification of the acquired image and the user operation instruction, so that the transparency of the electrochromic grating layer is changed, when the grating is displayed, the interface exposure can be automatically adjusted to ensure the shooting effect, meanwhile, the user can adjust the angle of the grating through the interaction interface, the incident light angle is selected, the glare or harmful reflection in the shooting process is eliminated, in addition, when the grating is displayed, if the shooting involves focusing and photometry operation, the electric field can be automatically adjusted to hide the grating layer before focusing photometry, the focusing photometry effectiveness is ensured, and the grating layer is displayed after the photometry focusing operation is completed to ensure the shooting effect.
It should be noted that, in implementation, a quarter wave plate may be added between the electrochromic grating of the single electrochromic camera module and the conventional lens assembly, so that in the actual shooting process, after the shooting parameters are adjusted by the user, two steps S205 and S206 of hiding the electrochromic grating and displaying the electrochromic grating can be omitted in the light measurement and focusing process. But the thickness of the electrochromic camera module is increased, so that the scheme can be selected according to the actual situation.
According to the embodiment, from the practical problem, the scheme that the electrochromic grating layer capable of realizing the polarizer function is internally provided with the camera module is provided by utilizing the characteristics of electrochromic materials, for example, the camera module of a mobile terminal such as a mobile phone solves the problem of low shooting quality caused by glare or harmful reflection, improves the shooting and shooting quality and user experience of the mobile terminal, and is suitable for intelligent terminal equipment with a camera used by a user to carry out specific photo and video shooting.

The input module mainly comprises two parts, namely image input and user operation input. The image input part mainly refers to a camera module of the mobile terminal, can acquire surrounding image information, and the whole camera module consists of one or more camera modules, wherein at least one camera module is an electrochromic camera module. The user operation input part is a module for acquiring instructions of a user for adjusting grating transparency, rotation angle, shooting focusing, shooting, video recording and the like in the shooting process, and comprises, but is not limited to, acquiring user operation on a touch screen or a key of the equipment.
Fig. 6 is a schematic diagram of a single electrochromic camera module of the mobile terminal according to the present invention, where the single electrochromic camera module, as shown in fig. 6, needs to include at least 5 major parts, which are a circuit substrate 1, a sensor photosensitive device 2, a focusing photometry component 3, a conventional lens component 4, and an electrochromic grating layer 5, respectively.
The difference between the electrochromic camera module and the common camera lens is mainly that the electrochromic grating layer 5 is a linear polarizer made of electrochromic materials, and the grating structure (the common grating interval is about 5 microns) is utilized to control the light passing in a single direction. The grating portion of the polarizer is capable of adjusting the visibility, i.e. transparency, of the grating itself under different electric fields to achieve both normal and polarized lens variations. Meanwhile, the electrochromic grating can rotate in angle according to the actual shooting environment and the requirement of a user, so that the aim of controlling the direction of an incident light source is fulfilled, and the electrochromic grating is shown in fig. 7a, 7b and 7 c.
It should be noted that, in this case, only the transparency and angle change of the single-layer electrochromic grating are involved, and after the multi-layer electrochromic grating structure is added, the structure combination can obtain more different shooting effects in the shooting process, so that the shooting experience of the user is enriched.
The judging module is used for judging the equipment state and giving the angle parameter and the transparency parameter of the electrochromic grating according to the specific information received by the input module. Meanwhile, other user operations in the shooting process are converted into identifiable shooting or adjusting instructions.
The control module controls the angle and the transparency of the electrochromic grating in the image input module by obtaining the conclusion of the judging module, and simultaneously controls the image input module, the calculating and storing module and the output module to execute specific shooting or adjusting operation.
The computing and storing module is used for storing specific contents shot by a user, and some preset instructions and specific parameters, including the angle parameters, the transparency parameters and the like of the current electrochromic grating.
The output module refers to an information interaction screen of the equipment and a user, and the user can observe the specific effect of current shooting in real time through the screen of the mobile terminal in the shooting process.
In the above modules, the judgment module, the control module, and the calculation part in the calculation and storage module may be implemented by a processor.
A practical case when a user takes a photograph is provided below.
The parameter presets before shooting include:
A. the electrochromic grating has an adjustable transparency in the range of 0% -100%,0% indicating that the grating is invisible, 100% indicating that the grating is fully visible, the grating being capable of blocking all incident light in its direction.
B. the electrochromic grating can be adjusted in an angle range of 0-180 degrees.
C. the initial state of the electrochromic grating is transparency 0% and angle 90 degrees.
D. the correspondence of the user interface adjustment bar to the electrochromic grating state is shown in fig. 8.
E. Normal exposure is maintained when the grating transparency is 0%; the exposure was increased by 20% when the raster transparency was 100% full display. The exposure to light increases between 0 and 100% in transparency vary linearly.
F. when the user photographed content is recognized as a landscape, an electrochromic barrier (transparency 100%, angle 90 degrees) is automatically displayed.
When a user shoots a landscape, the system automatically enters a polarization grating shooting mode after identifying a landscape element, and a transparency adjustment bar and an angle adjustment bar of an electrochromic grating for manual adjustment by the user appear in a user interface, as shown in the user interface of fig. 8. The system can firstly perform initial photometry and focusing operation and record the exposure degree of current shooting; the electric field parameters are adjusted, the transparency of the electrochromic grating is set to 100%, the angle is set to 90 degrees, and meanwhile, the exposure amount is increased by 20% on the basis of the current exposure. The effect of displaying the electrochromic grating layer after adjusting the exposure is displayed in real time in a shooting and framing interface of the user interface. The user can adjust the transparency adjusting bar and the angle adjusting bar in the interface according to the shooting effect displayed in the shooting view-finding interface, so as to adjust the state of the electrochromic grating layer and search the most suitable parameters of the current shooting scene. In the user adjusting process, if the light measurement and focusing change are needed to be carried out again, the electric field is adjusted to hide the electrochromic grating layer, after the light measurement and focusing are finished, the grating layer adjusted by the user is displayed, and the light measurement and focusing effectiveness is ensured. After the user finishes adjusting, clicking a shooting shutter button in the interface, and storing the current image by the system to support the user to view and preview or other later editing operations.
The terminal equipment of the embodiment utilizes electrochromic materials to manufacture the polarization grating and is arranged in the camera. When the method is applied specifically, the display transparency of the electrochromic grating is automatically controlled according to content identification and specific scenes; automatically optimizing photo exposure after grating display; the user can make manual parameter adjustments to the electrochromic grating layer.
Based on the characteristics of electrochromic materials, the embodiment of the invention provides a scheme of arranging an electrochromic grating layer capable of realizing the function of a polarizer in an imaging module of a mobile terminal such as a mobile phone and the like from the shooting scene of an actual user, solves the problem of low shooting quality caused by glare or harmful reflection, and can properly increase the exposure after displaying the grating to improve the shooting and shooting quality and user experience of the mobile terminal. In addition, as the grating transparency and the angle of the electrochromic grating layer can be adjusted, the problem of underexposure caused by the reduction of incident light after the polarizer is internally provided with the camera module in the prior art can be avoided for shooting non-reflective objects or shooting scenes such as water surface projection.
