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.
As shown in
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.
As shown in
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.

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.
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.
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.
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.
