Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Referring to fig. 1 to 3, the present embodiment provides a control method for an electronic device 100 of the present embodiment, where the electronic device 100 includes an imaging module 10, the imaging module 10 includes an image sensor 11 and an electrochromic element 12, and the electrochromic element 12 covers the image sensor 11. The control method comprises the following steps:
S10: judging whether the image acquired by the image sensor 11 is overexposed;
s20: when the image is overexposed, the light transmittance of the electrochromic element 12 is controlled to be lowered to reduce the exposure of the image.
referring to fig. 2 and fig. 3, the electronic device 100 according to the embodiment of the present disclosure further includes a processor 20, the processor 20 is connected to the electrochromic element 12 and the image sensor 11, the image sensor 11 is configured to sense light passing through the electrochromic element 12 to obtain image information, and the electrochromic element 12 can change its light transmittance under the action of a voltage. The above steps S10 and S20 can be implemented by the processor 20, that is, the processor 20 can be used to determine whether the image acquired by the image sensor 11 is overexposed and control the light transmittance of the electrochromic element 12 to be lowered to reduce the exposure of the image when the image is overexposed.
Specifically, in the present embodiment, the processor 20 is electrically connected to the image sensor 11 and the electrochromic element 12, and the processor 20 may provide a voltage to the electrochromic element 12 when the image acquired by the image sensor 11 is over-exposed, so that the light transmittance of the electrochromic element 12 is reduced, thereby enabling the exposure of the image acquired by the image sensor 11. It is understood that "exposure" herein refers to the degree of exposure of an image. The higher the exposure, the higher the brightness of the image and the whiter the image. The lower the exposure, the lower the brightness of the image, and the darker the image.
in the embodiment of the present application, the electronic device 100 may be an electronic device having imaging and photographing functions, such as a mobile phone, a digital camera, and a tablet computer. In addition, referring to fig. 2, in general, the electronic device 100 further includes a housing 30, the imaging module 10 is mounted on the housing 30, and the processor 20 is disposed inside the housing 30.
it can be understood that, at present, an image shot by a camera applied to a mobile terminal such as a mobile phone is prone to have an overexposure phenomenon, so that the image quality is affected due to an excessively bright image, and particularly in some scenes with particularly strong natural light, the problem of the excessively bright image still cannot be solved by adjusting parameters (such as exposure time and exposure gain) of the camera.
However, in the control method and the electronic device 100 of the embodiment of the application, the imaging module 10 is provided with the electrochromic element 12, and when the image is overexposed, the light transmittance of the electrochromic element 12 can be controlled to be reduced to adjust the exposure so as to reduce the exposure of the image, so that even in a scene with particularly strong light, the exposure can reach an ideal state, thereby realizing normal shooting without the problem of excessively bright image. Meanwhile, the usability of the imaging module 10 of the electronic device in a strong light scene is expanded, and the quality of a shot image is improved.
It is understood that, referring to fig. 1, in such an embodiment, the control method further includes the steps of:
S30: when the image is not overexposed, the image is saved.
Referring to fig. 2 and fig. 3, in some embodiments, step S30 may also be implemented by a processor, that is, the processor 20 may be configured to save the image when the image is not overexposed, that is, the electronic device 100 may normally capture and save the image through the imaging module 10 when the image is not overexposed.
Referring to fig. 4, in some embodiments, the imaging module 10 further includes a lens 13, the lens 13 is located above the image sensor 11, and the electrochromic element 12 is located between the image sensor 11 and the lens 13.
In this way, the light incident from the lens 13 is filtered by the electrochromic element 12 and then irradiated on the image sensor 11, so that the exposure of the image is reduced by changing the light transmittance of the electrochromic element 12.
Further, referring to fig. 4 and 5, the imaging module 10 further includes a package housing 14, the image sensor 11 and the lens 13 are disposed and packaged in the package housing 14, the lens 13 is at least partially exposed from the package housing 14, and the electrochromic element 12 is clamped in the package housing 14.
specifically, the package housing 14 includes a package substrate 141, a package side wall 142 and a package top plate 143, the image sensor 11 is carried on the package substrate 141, a card slot 1421 is formed on the package side plate 142, and the electrochromic element 12 is clamped in the card slot 1421. The package top plate 143 is formed with a light entrance window 1431, and the lens 13 is at least partially exposed from the light entrance window 1431.
It should be noted that the lens 13 is at least partially exposed from the package housing 14, which means that "the light entering from the light entrance window 1431 can smoothly enter the lens 13". Specifically, in the embodiment shown in fig. 4 and 5, the light entrance window 1431 may be a through hole opened on the package top plate 142, and the lens 13 may be at least partially located in the through hole to be at least partially exposed from the through hole. It is understood that in other embodiments, the light entrance window 1431 may be a portion of the package top plate 143, which is made of a transparent material, and is not limited herein.
In addition, referring to fig. 5, in some embodiments, the electrochromic element 12 may also be located above the lens 13, that is, the lens 13 is located between the electrochromic element 12 and the image sensor 11. In such an embodiment, the light is filtered by the electrochromic element 12 and then incident on the image sensor 11 through the lens 13. Specifically, referring to fig. 4 and 5, in such an embodiment, the electrochromic element 12 may be disposed on the upper surface of the package housing 14, for example, adhered to the package top plate 143 of the package housing 14 by glue.
In addition, with continued reference to fig. 4 and 5, in the above embodiment, the projection of the electrochromic element 12 on the plane where the lens 13 is located covers the lens 13.
in this way, when the electrochromic element 12 is located between the lens 13 and the image sensor 11, it is ensured that all light incident from the lens 13 passes through the electrochromic element 12 to filter all incident light.
referring to fig. 6, in some embodiments, the electrochromic element 12 includes an electrochromic layer 121, a first transparent electrode 122 and a second transparent electrode 123, the first transparent electrode 122 and the second transparent electrode 123 are connected to opposite sides of the electrochromic layer 121, and the first transparent electrode 122 and the second transparent electrode 123 are used for applying a voltage to the electrochromic layer 121.
the first transparent electrode 122 and the second transparent electrode 123 may be ITO conductive glass, the first transparent electrode 122 is a positive electrode, and the second transparent electrode 123 is a negative electrode. When the power is applied, the first transparent electrode 122, the second transparent electrode, and the electrochromic layer 121 form a current loop, so that the light transmittance of the electrochromic layer 121 is changed.
Further, in the embodiment of the present application, the electrochromic layer 121 may be made of an electrochromic material, and optical properties (reflectivity, transmittance, absorption, etc.) of the electrochromic material may undergo a stable and reversible color change under the action of an applied electric field, so that the electrochromic material may exhibit a reversible change in color and transparency in appearance.
specifically, when a voltage is applied to the electrochromic material through the electrodes, the transmission spectrum of the material changes due to the redox reaction or photoelectric transfer effect of the material. The electrochromic material can be polyaniline, polythiophene, polypyrrole and other conductive polymers, and the material is subjected to oxidation-reduction reaction under the action of voltage, so that the energy band structure of the material is changed, the color is changed, and the light transmittance of the material is changed. In addition, the electrochromic material can also be viologen or bipyridine, and when a voltage is applied to the electrochromic material, the color of the electrochromic material is changed due to strong photoelectric transfer among molecules, so that the light transmittance of the electrochromic material is changed.
Specifically, in the example shown in fig. 6, the electrochromic layer 121 is colorless in the absence of voltage, and the electrochromic layer 121 is changed to a colored state when power is applied. Referring to fig. 7, fig. 7 is a graph showing a relationship between voltage and transmittance, in which the horizontal axis represents time, the vertical axis represents transmittance, curve 1 represents voltage, and curve 2 represents transmittance of the electrochromic device 12. As can be seen from the graph, the transmittance of the electrochromic element 12 gradually decreases with time after the voltage is applied, and the transmittance of the electrochromic element 12 gradually increases after the power is turned off.
It is understood that in some embodiments, the electrochromic layer 121 may also have different light transmittance under different voltages. For example, each voltage may correspond to a light transmittance such that only a different voltage needs to be applied to the electrochromic element 12 to achieve the desired light transmittance.
further, referring to fig. 6, in some embodiments, the electrochromic element 12 further includes a first transparent substrate 125 and a second transparent substrate 126 which are disposed at intervals, and the first transparent electrode 122, the electrochromic layer 121, and the second transparent electrode 123 are stacked and disposed between the first transparent substrate 125 and the second transparent substrate 126.
in this way, the first transparent substrate 125 and the second transparent substrate 126 can support and support the electrochromic layer 121 and the transparent electrodes, and also can protect the electrochromic element 12 from being damaged by external pressure. In addition, the first transparent substrate 125 and the second transparent substrate 126 are colorless, and both do not affect the normal operation of the electrochromic device 12.
Specifically, the material of the first transparent substrate 125 may be blue glass. The main component of the blue glass is phosphate or fluorophosphate, which has higher absorptivity to infrared light, and the first transparent substrate 125 made of the blue glass has better filtering effect to infrared light, thereby being beneficial to improving the shooting quality. The material of the second transparent substrate 126 may be the same as or different from the material of the first transparent substrate 125. For example, the second transparent substrate 126 may be made of blue glass or conventional glass. The second transparent substrate 126 may also be made of PET (Polyethylene terephthalate), which has high film forming property, optical property and weather resistance, and the second transparent substrate 126 made of PET has good light transmittance. The second transparent substrate 126 may be made of a material with good light transmittance, such as PI (Polyimide).
In certain embodiments, the electrochromic element 12 may also be used to filter infrared light.
specifically, in the present embodiment, after the color of the electrochromic element 12 is changed, the infrared light can be absorbed, so that the imaging module 10 can omit an infrared filter, the thickness of the imaging module 10 can be reduced, the manufacturing cost can be saved, and the manufacturing difficulty can be reduced.
Referring to fig. 8, in some embodiments, step S20 may include the steps of:
S21: when the image is over-exposed, judging whether the exposure gain of the image sensor 11 is a preset gain value;
S22: when the exposure gain is a preset gain value, the light transmittance of the electrochromic element 12 is controlled to be lowered to reduce the exposure of the image. That is, step S20 may be implemented by step S21 and step S22.
Referring to fig. 2 and 3, in some embodiments, the steps S21 and S22 can be implemented by the processor 20. That is, the processor 20 is configured to determine whether the exposure gain of the image sensor 11 is a preset gain value when the image is overexposed and control the light transmittance of the electrochromic element 12 to decrease to reduce the exposure level of the image when the exposure gain is the preset gain value.
Specifically, the "exposure gain" of the image sensor 11 refers to a signal amplification factor of the image sensor 11. It is noted that, in the case of keeping other conditions (e.g., ambient brightness, exposure time, etc.) unchanged, the greater the exposure gain of the image sensor 11, the greater the brightness of the image, i.e., the greater the exposure; conversely, the smaller the exposure gain, the smaller the brightness of the image, i.e., the smaller the exposure. For each image sensor 11, there exists a minimum value of exposure gain at which the above-mentioned "preset gain value", i.e., the minimum value of exposure gain, may be understood with reference thereto when the same or similar descriptions are made elsewhere herein.
In the present embodiment, the exposure level of an image is related to the exposure time, the exposure gain of the image sensor 11, and the light transmittance of the electrochromic element 12. Specifically, the exposure level is smaller the lower the light transmittance is kept constant, the exposure level is larger the longer the exposure time is kept constant, and the exposure level is larger the exposure gain is kept constant. Therefore, in the present embodiment, when the image acquired by the image sensor 11 is overexposed, it is determined whether the exposure gain of the image sensor 11 is a preset gain value, and only when the exposure gain is the preset gain value, the light transmittance of the electrochromic element 12 is controlled to be lowered to reduce the exposure of the image. It is understood that under some scenes with particularly strong light, even if the exposure gain is adjusted to the preset gain, the overexposure will occur, and at this time, the problem of overexposure of the image can be avoided by controlling the light transmittance of the electrochromic element 12 to be reduced to reduce the exposure of the image.
Referring to fig. 8, in such an embodiment, when the determination result of step S22 is no, the control method further includes the steps of:
s23: the exposure gain of the image sensor 11 is controlled to be reduced to reduce the exposure of the image.
Specifically, after step S23, step S10 is re-entered to re-detect the exposure level of the image to determine whether the image is overexposed.
Referring to fig. 2 and 3, in some embodiments, the step S23 can be implemented by the processor 20, that is, the processor 20 can be configured to control the exposure gain of the image sensor 11 to be decreased to reduce the exposure of the image and to determine whether the image is overexposed again when the exposure gain does not reach the preset gain value.
specifically, in the present embodiment, when the image is overexposed, if the exposure gain is not the preset gain value, the exposure gain may be preferentially adjusted to the preset gain value. If the image is overexposed when the exposure gain is the preset gain value, the exposure level can be reduced by controlling the light transmittance of the electrochromic element 12 to be reduced.
With continued reference to fig. 9, in some embodiments, step S20 includes the steps of:
s24: when the image is over-exposed, judging whether the exposure time of the imaging module 10 is a preset time value;
S25: when the exposure time is a preset time value, the light transmittance of the electrochromic element 12 is controlled to be reduced to reduce the exposure of the image.
referring to fig. 2 and 3, in some embodiments, steps S24 and S25 can be implemented by the processor 20, that is, the processor 20 can be configured to determine whether the exposure time of the imaging module 10 is a preset time value when the image is overexposed, and control the light transmittance of the electrochromic device 12 to decrease to reduce the exposure of the image when the exposure time is the preset time value.
In the present embodiment, when the image obtained by the image sensor 11 is overexposed, it can be determined whether the image exposure time is a preset time value, and only when the exposure time is the preset time value, the light transmittance of the electrochromic element 12 is controlled to be reduced to reduce the exposure of the image. The above-mentioned "preset time value", i.e. the minimum value of the exposure time, can also be understood with reference to the same or similar descriptions at other locations herein.
therefore, when the image is overexposed, if the exposure time is not the preset time value, the exposure time can be preferentially adjusted to the preset time value. When the exposure is over-exposed and the exposure time is also the preset time value, the exposure can be reduced by controlling the light transmittance of the electrochromic element 12 to be reduced.
It is to be understood that, in the present embodiment, when the determination result of step S24 is no, that is, when the exposure time is not the preset time value, the control method further includes the steps of:
s26: the exposure time is controlled to be shortened to reduce the exposure of the image.
Specifically, in such an embodiment, after step S26, the process re-advances to step S10 to re-detect the exposure level of the image to determine whether the image is overexposed. It is understood that, in the present embodiment, when the image is overexposed, if the exposure time is not the preset time value, the exposure time may be preferentially adjusted to the preset time value. If the image is overexposed when the exposure time is the preset time value, the exposure level can be reduced by controlling the light transmittance of the electrochromic element 12 to be reduced.
referring to fig. 10, in some embodiments, step S20 includes the steps of:
S27: when the image is over-exposed, judging whether the exposure gain of the image sensor 11 is a preset gain value;
s28: when the exposure gain is a preset gain value, judging whether the exposure time of the imaging module 10 is a preset time value;
s29: when the exposure time is a preset time value, the light transmittance of the electrochromic element 12 is controlled to be reduced to reduce the exposure of the image.
Referring to fig. 2 and 3, in some embodiments, steps S27 to S29 can be implemented by the processor 20, that is, the processor 20 can be configured to determine whether the exposure gain of the image sensor 11 is a preset gain value when the image is overexposed, determine whether the exposure time of the imaging module 10 is a preset time when the exposure gain is the preset gain value, and control the light transmittance of the electrochromic device 12 to decrease when the exposure time is the preset time so as to reduce the exposure level of the image. Thus, the usability of the imaging module 10 of the electronic device in a strong light scene is expanded, and the quality of a shot image is improved.
In addition, please refer to fig. 10, in such an embodiment, when the determination result of the step S28 is no, that is, the exposure gain is not the preset gain value, the control method further includes the steps of:
S31: the exposure gain of the image sensor 11 is controlled to be reduced to reduce the exposure of the image.
after step S31, step S10 is re-entered to re-detect the exposure level of the image to determine whether the image is overexposed.
In addition, when the determination result of the step S29 is no, that is, the exposure time is not the preset time value, the control method further includes the steps of:
S32: the exposure time is controlled to be shortened to reduce the exposure of the image.
After step S31, step S10 is re-entered to re-detect the exposure level of the image to determine whether the image is overexposed.
Specifically, in such an embodiment, when the image is overexposed, it may be determined whether the exposure gain is a preset gain value, when the exposure gain is the preset gain value, it may be determined whether the exposure time is a preset time value, and when the exposure time is the preset time, the light transmittance of the electrochromic element 12 may be controlled to decrease to reduce the exposure of the image. That is, in the present embodiment, it is determined whether or not both the exposure gain and the exposure time are minimum, and only when both the exposure gain and the exposure time are minimum, the light transmittance of the electrochromic element 12 is controlled to be lowered to reduce the exposure of the image. It will be appreciated that under certain high light extraction scenarios, overexposure may occur even if the exposure gain and exposure time are adjusted to a minimum, and controlling the transmittance of the electrochromic element 12 to decrease the exposure of the image may reduce the exposure of the image so that the image does not suffer from overexposure. Thus, the usability of the imaging module 10 of the electronic device in a strong light scene is expanded, and the quality of a shot image is improved.
Note that, in such an embodiment, it is determined whether the exposure gain is minimum and then the exposure time is minimum. It is understood that, in other embodiments, it may also be determined whether the exposure time is the minimum first and then the exposure gain is the minimum second, and the order of the two is not limited.
Referring to fig. 11, in some embodiments, step S10 includes the steps of:
S11: acquiring the current exposure of the image;
s12: judging whether the current exposure is greater than a preset value;
S13: and when the current exposure is larger than a preset value, determining that the image is overexposed. That is, step S10 may be implemented by steps S11 to S13 described above.
with continued reference to fig. 2 and 3, in some embodiments, the above steps S11 to S13 can be implemented by the processor 20, that is, the processor 20 can be configured to obtain the current exposure of the image, determine whether the current exposure is greater than a preset value, and determine that the image is overexposed when the current exposure is greater than the preset value.
Specifically, the processor may include an auto exposure detection module that may automatically obtain a current exposure level of the image and then determine that the image is overexposed when the current exposure level is greater than a preset value. It should be understood that the "preset value" may be a preset value before the electronic device leaves the factory, or may be a value set by a user, and is not limited herein.
it is understood that, in such an embodiment, when the determination result of step S12 is no, that is, the current exposure is less than or equal to the preset value, the method proceeds to the step:
s14: and determining that the exposure of the image is normal. That is, the image is normally exposed and can be directly entered into the picture to be imaged.
In some embodiments, the step S14 can also be implemented by the processor 20, that is, the processor 20 can be configured to determine that the exposure level of the image is normal when the current exposure level is less than or equal to the preset value.
further, in some embodiments, step S20 may include the steps of:
The energization time of the electrochromic element 12 is changed so that the light transmittance of the electrochromic element 12 is lowered.
In some embodiments, the above steps may also be implemented by the processor 20, that is, the processor 20 may be configured to change the power-on time of the electrochromic element 12 to decrease the light transmittance of the electrochromic element 12.
Specifically, as can be seen from fig. 7 and the above, since the light transmittance of the electrochromic element 12 gradually decreases with the passage of time after the voltage is applied, the electrochromic element 12 can be decreased by changing the energization time of the electrochromic element 12.
Additionally, it is understood that in some embodiments, step S20 may include the steps of:
The magnitude of the applied voltage of the electrochromic element 12 is changed to decrease the light transmittance of the electrochromic element 12.
in some embodiments, the above steps can also be implemented by the processor 20, that is, the processor 20 can be used to change the magnitude of the applied voltage of the electrochromic element 12 to reduce the light transmittance of the electrochromic element 12.
Specifically, the electrochromic element 12 is in a transparent state when no voltage is applied, and the transmittance is highest at this time. When a voltage is applied, the electrochromic element 12 is colored, and the degree of coloring differs depending on the magnitude of the applied voltage, that is, the transmittance differs depending on the magnitude of the applied voltage, and therefore, the transmittance of the electrochromic element 12 can be reduced by changing the magnitude of the applied voltage of the electrochromic element 12.
The embodiment of the application also provides a computer readable storage medium. One or more non-transitory computer-readable storage media containing computer-executable instructions that, when executed by one or more processors 20, cause the processors 20 to perform the control method of any of the embodiments described above.
for example, the computer-executable instructions, when executed by the one or more processors 20, cause the processors 20 to perform the steps of:
S10: judging whether the image acquired by the image sensor 11 is over-exposed;
S20: when the image is overexposed, the light transmittance of the electrochromic element 12 is controlled to be lowered to reduce the exposure of the image.
