Abstract
The utility model discloses a close-range focusing device. The close-range focusing device comprises a picture, a light emitting component arranged on the upper end of the picture, and an imaging component arranged on the lower end of the picture; the light emitting component comprises an installation frame, LED lamps arranged inside the installation frame, a reflective mirror arranged on the upper ends of the LED lamps, and a light scattering sheet arranged on the lower ends of the LED lamps; and the imaging component comprises two convex lenses below the picture, a camera arranged below the two convex lenses, and a photosensitive chip arranged below the camera. Uniform light is emitted through the light emitting component, thereby ensuring a good imaging effect; with the two convex lenses being arranged between the picture and the camera, the distance between the camera and an equivalent picture of the picture is longer than an actual distance under a light gathering effect of the two convex lenses, the distance between the camera and the photosensitive chip is adjusted, and whether the focusing is completed or not is determined according to a predetermined standard and the imaging result of the photosensitive chip, thereby ensuring that a regulated definition range can be reached in the case of close-range focusing.
Description
Technical field
The utility model relates to a kind of close shot focus control.
Background technology
At present, along with science and technology development, mobile phone become people live communication in an indispensable part, in order to improve cell-phone function, the technology of change is impelled the development of mobile phone fast, and the mobile phone camera function occurs more and more, and this also is a development trend of following mobile phone.Increase camera at mobile phone and realize camera function, the camera focal length can be adjusted in certain scope by mechanism design, adapting to the shooting of distant view, thereby obtains imaging effect clearly.Yet prior art can't guarantee when close shot too clear.
Summary of the invention
Fundamental purpose of the present utility model be to provide a kind of when close shot close shot focus control equally clearly.
For addressing the above problem, the utility model adopts following technical scheme: a kind of close shot focus control comprises picture, and is arranged on the illuminating part of picture upper end, and is arranged on the imaging part of picture lower end; Described illuminating part comprises installing frame, and is arranged on the LED lamp in the installing frame, and is arranged on the reflective mirror of LED lamp upper end, and is arranged on the scattering sheet of LED lamp lower end; Described imaging part comprises two convex lens that are arranged on the picture below, and is arranged on the camera of two convex lens belows, and is arranged on the sensitive chip of camera below.
Further, described camera is provided with the adjusting ring of regulating distance between camera and the sensitive chip.
The beneficial effect of the utility model close shot focus control is: by illuminating part, can send uniform light, imaging effect is good; By between picture and camera, installing two convex lens additional, the light effect of converging by two convex lens makes the distance of the equivalent picture of camera and above-mentioned picture be distal to actual range, by regulating the distance of camera and sensitive chip, and determine whether that according to predetermined standard and sensitive chip imaging results focusing finishes, thereby realized the close shot focusing, reached the sharpness scope of regulation when guaranteeing the close shot focusing.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model close shot focus control.
Embodiment
See also shown in Figure 1ly, a kind of close shot focus control of the present utility model comprises picture 1, and is arranged on the illuminating part 2 of picture 1 upper end, and is arranged on the imaging part 3 of picture 1 lower end; Described illuminating part 2 comprises installing frame 20, and is arranged on the LED lamp 21 in the installing frame 20, and is arranged on the reflective mirror 22 of LED lamp 21 upper ends, and is arranged on the scattering sheet 23 of LED lamp 21 lower ends; Described imaging part 3 comprises two convex lens 30 that are arranged on picture 1 below, and is arranged on the camera 31 of two convex lens 30 belows, and is arranged on the sensitive chip 32 of camera 31 belows.
Described camera 31 is provided with the adjusting ring 33 of regulating distance between camera 31 and the sensitive chip 32.
The beneficial effect of the utility model close shot focus control is: by illuminating part, can send uniform light, imaging effect is good; By between picture and camera, installing two convex lens additional, the light effect of converging by two convex lens makes the distance of the equivalent picture of camera and above-mentioned picture be distal to actual range, by regulating the distance of camera and sensitive chip, and determine whether that according to predetermined standard and sensitive chip imaging results focusing finishes, thereby realized the close shot focusing, reached the sharpness scope of regulation when guaranteeing the close shot focusing.
The above only is embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
