That is, the processor or the terminal may implement the control method of the terminal device provided by the embodiment of the present invention by running the software program in the android operating system.
The terminal equipment in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. The mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), etc.; the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like; the embodiments of the present invention are not particularly limited.
The first embodiment,
An embodiment of the present invention provides a terminal device, and specifically, as shown in fig. 2, the terminal device includes: a lens 11, an image sensor 12, a control module 13 and a display 14.
The image sensor 12 is located on the light emitting side of the lens 11, and the image sensor 12 and the display screen 14 are both electrically connected to the control module 13.
Specifically, the lens 11 in the embodiment of the present invention includes: a plurality of optical lenses for adjusting the received ambient light and outputting the modulated ambient light to the image sensor 12 at an output side; the image sensor 12 may be a Metal-Oxide Semiconductor (CMOS) image sensor.
When an image is shot through a camera module consisting of the lens 11 and the image sensor 12, the image sensor 12 is used for receiving ambient light through the lens 11 and sensing the received ambient light to generate a first electric signal, and the control module 13 is used for converting the first electric signal into an image signal.
That is, when the image is captured by the image capturing module comprising the lens 11 and the image sensor 12, the working principle and the working state of each component (the lens 11, the image sensor 12, and the control module 13) are the same as those in the prior art, so that firstly, the embodiment of the present invention can ensure that the image capturing module comprising the lens 11 and the image sensor 12 can capture images normally.
When an image is not shot through the camera module consisting of the lens 11 and the image sensor 12 and the display screen 14 displays a picture, the image sensor 12 is configured to receive ambient light through the lens 11 and sense the received ambient light to generate a second electrical signal, and the control module 13 is configured to determine the brightness of the ambient light according to the second electrical signal and adjust the display brightness of the display screen 14 according to the brightness of the ambient light.
For example, the application scene in which no image is captured by the camera module consisting of the lens 11 and the image sensor 12 and the display screen 14 displays a picture may include: the terminal device browses a webpage, plays games, edits characters, and takes pictures, videos, and video calls through other camera modules of the terminal device, which is not limited in the embodiment of the present invention, and the camera module which is not composed of the lens 11 and the image sensor 12 takes pictures and the display screen 14 displays pictures (which are not standby interfaces).
Further, referring to fig. 3, fig. 3 shows the response sensitivity of the image sensor in the conventional camera module to light with different wavelengths (shown by the solid curve in fig. 3) and the response sensitivity of the photosensitive device in the conventional photosensitive detection module to light with different wavelengths (shown by the dashed curve in fig. 3). As can be seen from the response sensitivity curve of the image sensor in fig. 3 to the light with different wavelengths, the wavelength range of the light that the image sensor can respond to is 400nm to 1000nm, the response sensitivity curve of the photosensitive device commonly used for photosensitive detection to the light with different wavelengths can be seen, the wavelength range of the light that the photosensitive device can respond to is 400nm to 700nm, and the response spectral range of the photosensitive device completely falls within the response spectral range of the image sensor, so that the image sensor in the camera module can be used to accurately detect the brightness of the ambient light.
It should be noted that, since the wavelength range to which the photosensor can respond falls entirely within the wavelength range of the light to which the image sensor can respond, the operating state of the image sensor in the above-described embodiment when capturing an image may thus be the same as the operating state when no image is captured and the display screen displays a picture, however, because the wavelength range which needs to be sensed by the image sensor is longer when the image is shot, the power consumption of the image sensor is larger, if the image sensor is operated in the working state when the image is shot when the image is not shot and the display screen displays the image, the power consumption of the terminal device is greatly increased, so that the operating state of the image sensor when shooting images can be different from the operating state when not shooting images and the display screen displays images, and the wavelength range sensed by the image sensor when the image is shot is larger than the wavelength range when the image is not shot and the display screen displays the picture.
The terminal device provided by the embodiment of the invention comprises: the device comprises a lens, an image sensor, a control module and a display screen; the image sensor is positioned on the light emitting side of the lens and electrically connected with the control module; when the camera module consisting of the lens and the image sensor is used for shooting an image, the image sensor is used for receiving ambient light through the lens and sensing the received ambient light to generate a first electric signal, the control module is used for converting the first electric signal into an image signal, when the camera module consisting of the lens and the image sensor is not used for shooting the image and the display screen displays a picture, the image sensor is used for receiving the ambient light through the lens and sensing the received ambient light to generate a second electric signal, and the control module is used for determining the brightness of the ambient light according to the second electric signal and adjusting the display brightness of the display screen according to the brightness of the ambient light. When the image is shot through the camera module, the ambient light received by the image sensor of the camera module generates a first electric signal and then is converted into an image signal; the method comprises the steps of generating a second electric signal through ambient light received by an image sensor of a camera module when an image is not shot through the camera module and a display screen displays a picture, determining the brightness of the ambient light according to the second electric signal, and adjusting the display brightness of the display screen according to the brightness of the ambient light.
Optionally, when the camera module consisting of the lens 11 and the image sensor 12 is used to capture an image, the control module 13 is further configured to determine the brightness of the ambient light according to the first electrical signal, and adjust the display brightness of the display screen 14 according to the brightness of the ambient light.
In the above embodiment, when the image is captured by the camera module including the lens and the image sensor, the control module is further configured to determine the brightness of the ambient light according to the first electrical signal, and adjust the display brightness of the display screen according to the brightness of the ambient light, so that the display brightness of the display screen can also be adjusted when the image is captured by the camera module including the lens and the image sensor.
Optionally, referring to fig. 4, the terminal device provided in the embodiment of the present invention may further include: a lens barrel 15, an infrared filter 16, a Printed Circuit Board (PCB) and/or a Flexible Printed Circuit Board (FPC);
the lens barrel 15 forms an accommodating cavity for accommodating the lens 11 and is used for fixing the lens 11; the infrared filter 16 is located between the light-emitting side of the lens 11 and the image sensor 12, and is used for filtering infrared light in the ambient light output by the lens 11; PCB) and/or FPC is electrically connected to the image sensor 12 for conducting electrical signals generated by the image sensor 12.
Still further, referring to fig. 5, fig. 5 shows the response sensitivity of the image sensor in the conventional camera module to the light rays with different angles of view (shown by the solid curve in fig. 5) and the response sensitivity of the photosensitive device in the conventional photosensitive detection to the light rays with different angles of view (shown by the dashed curve in fig. 5). As can be seen from fig. 5, the field angle of light received by the image sensor is about 80 °, and the field angle of light received by the photosensor exceeds 120 °, if the photosensor is directly used for detecting the environment of the image sensor of the camera module, the image sensor of the camera module can only detect light within the field range of the camera module, as shown in fig. 6, the light exceeding the wide-angle light within the field range of the camera module is limited by the fact that the structure of the camera module cannot reach the image sensor of the camera module, and therefore if the angle of ambient light exceeds the field angle of the image sensor of the camera module, the brightness of ambient light cannot be accurately detected, and further the display brightness of the display screen of the terminal device cannot be accurately adjusted.
In order to avoid the above problem, referring to fig. 7, the terminal device according to the embodiment of the present invention further includes: a diffusion module 18 located on the light incident side of the lens 11;
when the camera module consisting of the lens 11 and the image sensor 12 is used for shooting images, the diffusion module 18 is used for transmitting ambient light;
when an image is not captured by the camera module consisting of the lens 11 and the image sensor 12 and a picture is displayed on the display screen 14, the diffusion module 18 is configured to diffuse ambient light input into the lens 11.
That is, when the image is captured by the camera module comprising the lens 11 and the image sensor 12, the diffusion module 18 does not diffuse the ambient light but directly transmits the ambient light, so as to ensure that the camera module can normally capture images, and when the image is not captured by the camera module comprising the lens 11 and the image sensor 12 and the display screen 14 displays a picture, the diffusion module diffuses the ambient light input into the lens 11, so that the situation that the environment with an incident angle larger than the field angle of the camera module cannot be detected by the image sensor of the camera module can be avoided, and the brightness of the ambient light can be accurately detected.
Further, optionally, referring to fig. 8, the diffusion module 18 includes: a first light-transmitting electrode layer 181, a second light-transmitting electrode layer 182, and a liquid crystal layer 183 located between the first light-transmitting electrode layer 181 and the second light-transmitting electrode layer 182.
For example, the light-transmitting electrode may be made of a light-transmitting conductive material such as Indium Tin Oxide (ITO) or graphene.
The operation principle of the diffusion module 18 according to the above embodiment will be described below with reference to fig. 9 and 10.
First, referring to fig. 9, in one state of the diffusion module 18, the liquid crystal molecules in the liquid crystal layer 183 do not need to be aligned, and at this time, the diffusion module 18 scatters and transmits the received light.
Next, referring to fig. 10, when the diffusion module 18 is in another state, the liquid crystal molecules in the liquid crystal layer 183 need to be aligned, and at this time, the diffusion module 18 directly transmits the received light.
For example, the state shown in fig. 9 may be a state when both the first light-transmitting electrode contact 181 and the second light-transmitting electrode contact 182 are turned on at a low level, and the state shown in fig. 10 may be a state when the first light-transmitting electrode contact 181 is turned on at a low level and the second light-transmitting electrode contact 182 is turned on at a high level.
Optionally, the low level may be a reference ground of the terminal device, and the high level may be a power supply voltage of the terminal device; that is, when an image is captured by the camera module including the lens and the image sensor, a reference ground voltage is input to the first transparent electrode contact 181 and a power voltage is input to the first transparent electrode contact 181, and when an image is not captured by the camera module including the lens and the image sensor and a screen is displayed on the display screen, a reference ground voltage is input to both the first transparent electrode contact 181 and the second transparent electrode 182.
Optionally, the terminal device further includes: the light-transmitting cover plate is arranged on the light incidence side of the lens; the diffusion module is packaged in the light-transmitting cover plate.
Specifically, the light-transmitting cover plate is arranged on the light-incident side of the lens 11 of the terminal equipment camera module to play a role in protecting the lens 11 from dust and water, and in order to realize a photosensitive function by using the camera module without increasing structural burden and volume, the diffusion module 18 can be packaged in the light-transmitting cover plate in front of the lens 11 in the embodiment of the invention.
