       BACKGROUND ART 
       [0002]    Flashlight is an artificial light source used in photography. When the shutter of a camera is pressed down, the flashlight usually lights the scene within 1/10000 seconds to 1/20 seconds. However, with the development of digital technology and the popularity of photography, hot shoe-style flashlight has been widely used in photography as it can provide with a more professional flashing effect. 
         [0003]    Before photographing via a hot shoe-style flashlight, one must first set the parameters of the flashlight such as its working status, to produce various photographic effects in different light conditions via the adjustment of flashlight parameters. However, as shown in  FIG. 1 , during the setting of parameters of the existing flashlights, only the value or symbol of the corresponding parameter is displayed. For a number of users, they may understand the meaning represented by the value or the symbol only after reviewing the specification.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0031]    Hereinafter, technical solution in embodiments of the present invention will be fully described, taken in conjunction with the drawings in the embodiments of the present invention. As can be seen, the embodiments illustrated are only a part of all possible embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments that can be practiced by persons of ordinary skill in the art without exerting undue creative effort shall fall within the protective scope of the present invention 
         [0032]    According to one embodiment of the present invention, there is provided a flashlight. As shown in  FIG. 2 , the flashlight includes an input module  201 , a first main control module  202  connected to the input module  201 , a display  203  connected to the first main control module  202 . Wherein, the input module  201  is a keypad circuit, through which different information may be input via pressing different keypads; the display  203  is color display, preferably color liquid crystal display. 
         [0033]    The input module  201  is used to input a first input information. The first input information is used to trigger the first main control module  202  to adjust output mode of the flashlight; the output mode of the flashlight is an output mode comprising flashlight parameters and parameter names; the first main control module  202  is used to receive the first input information, determine output mode of the flashlight corresponding to the first input information, and generate a first control instruction corresponding to the output mode; the display  203  is used to receive the first control instruction, and output the flashlight parameters and parameter names according to the first control instruction. 
         [0034]    In addition, the input module  201  is also used to receive a second input information; the second input information is used to trigger the first main control module  202  to adjust display mode of the flashlight; the display mode is a display mode comprising display language and color of the flashlight parameters; the first main control module  202  is also used to receive the second input information, determine display mode of the flashlight corresponding to the second input information, and generate a second control instruction corresponding to the display mode; the display  203  is also used to receive the second control instruction, and output display language and color of the flashlight parameters according to the second control instruction. 
         [0035]    In the present embodiment, the display  203  has multiple display zones, with different display zones display different parameters and their names. Wherein, the parameters displayed in different output mode are different, and the corresponding display zones are different as well. 
         [0036]    As shown in  FIG. 3 , taking the Chinese display interface of repetition mode as an example, the display zone  2031  displays name of the flashing mode of the flashlight, the display zone  2032  displays value and name of the frequency corresponding to the flashing mode, the display zone  2033  displays value and name of times, the display zone  2034  displays value and name of power, and the display zone  2035  displays value and name of focal length. As such, users can directly understand the meaning of the parameters by referring to their names, which will help the users set those parameters. 
         [0037]    In different display modes, the color of different display zones of the display  203  may be different, and the language of the parameters displayed may be different as well. Different languages can be made available, such as Chinese, English, Portuguese or Spanish. Since different display zones correspond to different colors, colors of different display zones may be set and combined in any ways so that the flexibility in the design of the display interface of display  203  may be improved and the colors of the display interface may be enriched. For example, the display zone  2031  and the display zone  2032  may have different colors. For instance, the display zone  2031  is orange and the display zone  2032  is yellow; or the display zone  2033  and the display zone  2034  may have the same color; for instance, the display zone  2033  and the display zone  2034  are both in light blue. 
         [0038]    As shown in  FIG. 2 , in addition to the input module  201 , the first main control module  202  and the display  203 , the flashlight provided in the present embodiment can also include a stepper motor  204 , a voltage-stabilizing circuit  205  and a voltage boosting and stabilizing charging circuit  206  connected to the first main control module  202 ; and a power source  207  connected to the voltage-stabilizing circuit  205  and the voltage boosting and stabilizing charging circuit  206  and the first main control module  202 , wherein, the power source  207  may be a 6 V battery, and may also be a mains electricity power source, used for supplying voltage for the first main control module  202  and so on; and a capacitor  208  connected to the first main control module  202  and the voltage boosting and stabilizing charging circuit, wherein the first main control module  202  determines whether the voltage of the capacitor  208  is relatively low according to the feedback voltage from the capacitor  208 , and supplies power to the capacitor  208  when the voltage of the capacitor  208  is relatively low and trigger the capacitor to store power. 
         [0039]    In the present embodiment, the first main control module  202  realize the input, display and control of signals via the connected input circuit  201 , display  203  and voltage-stabilizing circuit  205 . In addition, the flashlight of the present embodiment can also include a second main control module  209  connected to the first main control module  202 . The flashlight may be triggered and its communication with the camera may be realized via the wireless instruction receiving module  210 , the camera hot shoe connector  211 , the light sensor module  212 , the trigger circuit  213 , and the like, connected to the second main control, module  209 . The trigger circuit  213  can be connected to the flashlight tube  214  to control the on or off function of the flashlight tube  214 . 
         [0040]    Preferably, the first main control module  202  and the second main control module  209  are connected via USART (Universal Synchronous/Asynchronous Receiver/Transmitter), thus realizing synchronous interaction of information between the first main control module  202  and the second main control module  209 . Compared with the conventional flashlight in the art which only adopts one main control module, the flashlight in the present embodiment adopts two main control modules, which increases the processing speed and shortens the response time of the flashlight tube. 
         [0041]    In addition, the first main control module  202  is also connected to a high temperature monitoring module  215  to monitor temperature of the first main control module so as to prevent any deleterious effect on the performance of the flashlight caused by over-heating of the first main control module due to high temperature; the second main control module  209  is also connected to the a buzzer alarm module  216  to trigger an alarm when the flashlight is in an abnormal working condition. 
         [0042]    Parameters of the flashlight provided in the present embodiment can include flashing mode, power, flashing times, focal length or frequency and the like, in which the flashing mode can include TTL (Through The Lens) mode, manual mode, repetition mode, wireless mode and custom mode. Moreover, the flashing mode and names of relevant parameters in the present embodiment may be displayed in various languages, including Chinese, English, Portuguese and Spanish. In the present invention, the display mode of the display  203  is illustrated using two of the available language options, namely Chinese and English languages as examples. 
         [0043]    The Chinese and English display modes of the TTL mode are shown in  FIG. 4A  and  FIG. 4B  respectively. Different display zones display different values and their corresponding parameter names so that users can readily understand the meaning of those values. For those beginners and amateurs, the TTL mode is the safest and most convenient mode in complicated environments. In this mode, users can obtain desired photographic effect through simple adjustments of the parameters. In the TTL auto mode, the flashlight will pre-flash once and automatically provide an output value after combining information such as exposure control and focal length obtained after the pre-flash. That is to say, in the auto mode, users can set various parameters of the camera according to their personal practical needs regardless of the output value of the flashlight. 
         [0044]    The Chinese and English display options of the manual mode are shown in  FIG. 5A  and  FIG. 5B  respectively. When manual exposure is needed, the flashlight may be changed into manual mode, namely M mode, to manually adjust the focal length and thus the requirement of individual users may be satisfied. In this mode, the flashlight can match the camera&#39;s rate to continuously shoot at a high speed, and can also select different exposure output. 
         [0045]    The Chinese and English display options for the repetition mode or the Multi mode are shown in  FIG. 6A  and  FIG. 6B  respectively. After the Multi mode is selected, the flashing times/repetitions, flashing frequency and output value can be adjusted respectively. 
         [0046]    The Chinese and English display options for the wireless mode are shown in  FIG. 7A  and  FIG. 7B  respectively. The flashlight provided in the present embodiment may receive wireless signals of main control modes from the built-in flashlight or hot shoe flashlight of a camera, thereby allowing off-the-camera creative flashing. 
         [0047]    Alternatively, the flashlight is also provided with a custom mode for setting custom function and language display and the like of the flashlight, wherein the Chinese and English display modes/options are shown in  FIG. 8A-8D  respectively. 
         [0048]    In the display mode as described above, what the flashlight displays are the full names (descriptions) of the parameters in English. Although English abbreviations can also be used to represent or illustrate the meaning of the parameters, it is generally known that the same English abbreviation may not bear a unique meaning. For example, EV may be the English abbreviation of Exposure-Value, but may also be the English abbreviation of Electron-Volt, the unit of energy used in the non-international unit system. Therefore, users may not readily and directly determine the meaning of the parameters according to their English abbreviations. They still need to review the specification, which can frustrate rather than help to expand the utilization and application of flashlights by the general public. However, in other embodiments of the present invention, when the display language of the flashlight is in another language, Portuguese for example, the users can adjust the camera to output abbreviations of the parameter names in the output mode to replace the full names of the parameters only if they can unambiguously determine the meaning of the parameters according to the abbreviation of the parameter names. 
         [0049]    For the flashlight provided in the present embodiment, after the input module inputs the first input information, the first main control module determines output mode of the flashlight according to the first input information, and generates the corresponding first control instruction. The display outputs the flashlight parameters and the parameter names according to the first control instruction. Since the flashlight provided in the present invention may display not only the values of parameters and but also their names, users may be able to directly understand the meaning of the parameters according to the parameter names without having to view the specification, which will further facilitate the widespread use of flashlight. 
         [0050]    Besides, for the flashlight provided in the present embodiment, after the input module inputs the second input information, the first main control module may determine the display mode of the flashlight according to the second input information, and generate the corresponding second control instruction. The display may output the display language and color of the flashlight parameters according to the second control instruction. Since the flashlight provided in the present embodiment can adopt various languages to display the paramaters, it can readily be used by users in different countries and expand the application and scope of flashlights. Moreover, different display zones may display different colors, which will enrich the color of the display interface of the flashlight. 
         [0051]    Each embodiment of the present invention is described in a progressive manner, with the focus of each embodiment different from all other embodiments, and the identical portion between different embodiments may be referred to each other. With the above description of the disclosed embodiments, persons skilled in the art will be able to realize or use the present invention. Furthermore, various modifications to those embodiments will become apparent to persons skilled in the art. The general principle defined herein may be realized in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to those embodiments as illustrated herein, but should be in accordance with the broadest scope having the same principle and novel characteristics as disclosed in the present invention.
