Abstract
The utility model discloses a camera with an automatic shooting brightness adjustment function. The camera comprises a machine body, wherein a supplementary lighting lamp and a photosensitive bar are mounted on the machine body; a photoreceptor, an A/D (Analog/Digital) converter, an amplifier, a digital signal processor and a controller are mounted in the machine body; the photosensitive bar is connected with the photoreceptor; the photoreceptor is connected with the digital signal processor through the A/D converter and the amplifier; and the digital signal processor is connected with the supplementary lighting lamp through the controller. Compared with the prior art, the utility model achieves the purpose that the brightness of the supplementary lighting lamp can be automatically adjusted according to the external shooting environment, so that the brightness required by the shooting effect can be optimally adjusted, and the problems of much difficulty, inaccuracy and poor effect in manual adjustment are solved.
Description
Technical field
The utility model relates to video camera, is specially the self-adjustable video camera of a kind of shooting brightness, to realize video camera under the different light rays environment, to taking the automatic adjustment of brightness.
Background technology
Image that video camera is in use captured and video and ambient light have much relations, if ambient light is brighter, then light is brighter for then corresponding institute images displayed; If ambient light is darker, the then captured video that goes out is then felt more secretly or is fuzzyyer.
Occur for fear of above-mentioned situation, guarantee shooting effect, can on video camera, increase the light filling lamp usually; With through opening or close the light that the light filling lamp is regulated shooting environmental; But present video camera light filling lamp need carry out manual adjustments usually, and for unprofessional user, it exists the adjusting difficulty big; Inaccurate, the problem of regulating effect difference.
The utility model content
For this reason, the purpose of the utility model is to provide a kind of shooting brightness self-adjustable video camera, and to realize the automatic adjusting of video camera light filling lamp, solving present light filling lamp, to regulate existing adjusting difficulty big, inaccurate, the problem of regulating effect difference.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
The self-adjustable video camera of a kind of shooting brightness; Comprise body (1); Light filling lamp (2) and sensitization bar (3) are installed on the wherein said body (1); Photoreceptor (5), A/D converter (6), amplifier (7), digital signal processor (8) and controller (9) are installed in the body (1); Said sensitization bar (3) is connected with photoreceptor (5), and photoreceptor (5) is connected with digital signal processor (8) through A/D converter (6), amplifier (7), and digital signal processor (8) is connected with light filling lamp (2) through controller (9).
The utility model receives light from outside through the sensitization bar; And the light situation of change fed back to photoreceptor, photoreceptor produces induced signal accordingly, converts digital signal to through A/D converter; Send to digital signal processor after amplifying through amplifier again; Send to controller through digital signal processor, controller is controlled reply light filling lamp, and the brightness of its generation is regulated thereupon.Compared with prior art; The utility model has realized that the brightness of light filling lamp automatically adjusts with extraneous shooting environmental; Make the required brightness of shooting effect adjust to the best, avoided the existing adjusting difficulty of manual adjustments big, the problem of inaccurate and regulating effect difference.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the system principle diagram of the utility model.
Identifier declaration among the figure: body 1, light filling lamp 2, sensitization bar 3, display screen 4, photoreceptor 5, A/D converter 6, amplifier 7, digital signal processor 8, controller 9.
Embodiment
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
See also Fig. 1, shown in Figure 2, Fig. 1 is the structural representation of the utility model; Fig. 2 is the system principle diagram of the utility model.
The utility model provides the self-adjustable video camera of a kind of shooting brightness, is used to realize that the brightness of light filling lamp automatically adjusts with extraneous shooting environmental, and it is big to have solved the existing adjusting difficulty of manual adjustments, the problem of inaccurate and regulating effect difference.
This video camera wherein; Comprise body 1, be installed in display screen 4, light filling lamp 2 and sensitization bar 3 on the body 1, said light filling lamp 2 is used for when ambient light need be regulated, opening; So that the shooting function reaches the best shooting effect of finding a view; Sensitization bar 3 is to light sensor, and it can change to produce accordingly and change according to extraneous light, is used to gather extraneous light information.
When wherein sensitization bar 3 is sensed the variation of external environment condition light, the corresponding photoreceptor that the is attached thereto 5 corresponding photoinduction signals that produce, described photoinduction signal is converted into digital signal afterwards through A/D converter 6; Digital signal is amplified through amplifier 7 again; Be input to digital signal processor 8,8 pairs of these signals of digital signal processor are handled, and obtain corresponding with it brightness numerical signal; These numerical signals send to controller 9; Control 9 devices then according to these corresponding brightness numerical value, the brightness of corresponding adjusting light filling lamp 2 is complementary the brightness of light filling lamp 2 and brightness numerical value.
Hence one can see that; The utility model has realized that the brightness of light filling lamp automatically adjusts with extraneous shooting environmental; Make the required ambient brightness of video camera shooting effect adjust to the best, avoided the existing adjusting difficulty of manual adjustments big, the problem of inaccurate and regulating effect difference.
More than be that a kind of self-adjustable video camera of brightness of taking that the utility model is provided has carried out detailed introduction; Used concrete example among this paper the structural principle and the execution mode of the utility model are set forth, above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (1)
1. take the self-adjustable video camera of brightness for one kind; Comprise body (1); It is characterized in that being equipped with on the said body (1) light filling lamp (2) and sensitization bar (3); Photoreceptor (5), A/D converter (6), amplifier (7), digital signal processor (8) and controller (9) are installed in the body (1); Said sensitization bar (3) is connected with photoreceptor (5), and photoreceptor (5) is connected with digital signal processor (8) through A/D converter (6), amplifier (7), and digital signal processor (8) is connected with light filling lamp (2) through controller (9).
