Abstract
The utility model discloses a mobile phone capable of automatically dimming. The mobile phone comprises a mobile phone body which comprises a camera and a display screen and an automatic dimming module which is connected with the mobile phone body. The automatic dimming module comprises a first light intensity analog-digital conversion unit which is for converting analog quantity of first moment illumination obtained by the camera into digital quantity and keeps the digital quantity as illumination information of a first moment, a second light intensity analog-digital conversion unit which is for converting analog quantity of second moment illumination obtained by the camera into digital quantity and keeps the digital quantity as illumination information of a second moment, and a comparator which is for comparing the illumination information of the first moment and the illumination information of the second moment, and outputs brightness which adjusts the brightness of the display screen to be matched with the illumination signal of the second moment if the difference of a comparison value is larger than a pre-set value to the mobile phone body. The mobile phone capable of automatically dimming is lighter and more convenient, and lower in cost.

The lightening trend that becomes development of mobile phone, in prior art, realizes distance and photoinduction, common smart mobile phone use special-purpose distance perspective should with surround lighting induction chip, people are finding more low-cost, realize more easily the mobile phone of distance and photoinduction.
Utility model content
In order to solve above technical problem, the purpose of this utility model is to propose cheaply a kind of, can realize mobile phone with an automatic light meter more easily.
The utility model discloses a kind of mobile phone with an automatic light meter of realizing, comprise the mobile phone body with camera and display screen, also comprise the module with an automatic light meter being connected with described mobile phone body, described module with an automatic light meter comprises:
The first luminous intensity AD conversion unit, converts digital quantity to for the analog quantity of the first constantly illumination that described camera is obtained, and saves as the first illumination information constantly;
The second luminous intensity AD conversion unit, converts digital quantity to for the analog quantity of the second constantly illumination that described camera is obtained, and saves as the second illumination information constantly;
Comparator, for the illumination information in the first described moment and second illumination information is constantly compared, if comparison value difference surpasses default numerical value, the brightness that the illumination signal that is second moment with described to described mobile phone body output by the brightness adjustment of described display screen matches.
Described in the utility model, realize in mobile phone with an automatic light meter, also comprise the power supply unit of powering for all consuming parts of the mobile phone body to described.
Described in the utility model, realize in mobile phone with an automatic light meter, described power supply unit comprises lithium battery.
Described in the utility model, realize in mobile phone with an automatic light meter, described display screen is LCD/LED display screen.
Described in the utility model, realize in mobile phone with an automatic light meter, in described comparator, have for adding up the time counter of the comparison value duration length of described difference.
Implement a kind of mobile phone with an automatic light meter of realizing of the present utility model, there is following useful technique effect:
Being different from people in prior art needs distance perspective to realize the function of light sensation with the special chip of surround lighting induction, and the technical program can be removed this special chip, utilizes module with an automatic light meter, reduces mainboard cost, lighter.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the functional-block diagram of realizing mobile phone with an automatic light meter of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of mobile phone with an automatic light meter 1 of realizing, comprises the mobile phone body 30 with camera 10 and display screen 20, also comprises the module with an automatic light meter 40 being connected with mobile phone body 30, and module 40 with an automatic light meter comprises:
The first luminous intensity AD conversion unit 401, converts digital quantity to for the analog quantity of the first constantly illumination that camera 10 is obtained, and saves as the first illumination information constantly;
The second luminous intensity AD conversion unit 402, converts digital quantity to for the analog quantity of the second constantly illumination that camera 10 is obtained, and saves as the second illumination information constantly;
Comparator 403, for the illumination information in first moment and second illumination information is constantly compared, if comparison value difference surpasses default numerical value, the brightness to mobile phone body 30 outputs, the brightness adjustment of display screen 20 being matched for the illumination signal with second moment.
Wherein, also comprise the power supply unit 50 for powering to all consuming parts of mobile phone body 30.
Power supply unit 50 comprises lithium battery.
Display screen 20 is LCD/LED display screen.
In comparator 403, have for adding up the time counter of the comparison value duration length of described difference.
Service time, counter was, if comparison value difference is large, the duration is longer, just start dimming function, to prevent that user misoperation from also having caused light modulation, for example user has covered the display screen of mobile phone because of carelessness with hand, time is shorter, just there is no need to have started dimming function.
The using method of this mobile phone can be: in use open front-facing camera 10, in mobile phone communication, record ambient light intensity CD1 (the illumination information in first moment), when mobile phone communication is pressed close to after people's face, a little less than the luminous intensity of camera 10 will become extremely, record CD2 (the illumination information in second moment), by comparator 403 relatively after, when CD1 and CD2 difference are when larger, automatic closing hand phone is backlight or adjust LCD brightness, uses camera 10 rather than special-purpose distance and surround lighting chip detection distance and ambient light intensity on mobile phone.
Implement a kind of mobile phone with an automatic light meter of realizing of the present utility model, there is following useful technique effect:
Being different from people in prior art needs distance perspective to realize the function of light sensation with the special chip of surround lighting induction, and the technical program can be removed this special chip, utilizes module with an automatic light meter, reduces mainboard cost, lighter.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
