Abstract
The utility model discloses a video-camera lens focus acousto-optic indicating device, which comprises a set shell 1, a core 2 that is positioned in the shell 1 and a speaker 3; wherein, a focusing indication lamp 9 is positioned on the front panel of the shell 1, a video image signal input jack 4 is positioned on the side surface of the shell 1, and the speaker 3, focusing indication lamp 9 and the video image signal input jack 4 are separately connected with the core 2. The utility model has the advantages of that is able to rapidly and correctly remind that whether the lens of the video camera need focus, which has small volume and light weight and is convenient to carry with one person could complete the focus commissioning of the video camera, and is an ideal video-camera lens commissioning tool for the professional technical personnel and the public users.
Description
Technical field
The utility model relates to a kind of camera lens focus indicating device, particularly relates to a kind of camera lens focus acousto-optic indicating device.
Background technology
Develop rapidly along with science and technology, video monitoring to management and monitoring and production and operation monitoring development, has been penetrated into multiple fields such as government, education, culture, place of public amusement, hospital, hotel, industry, urban safety by traditional safety technological guard monitoring.The basic process of video monitoring is: scene being shot is by the refraction of lens optical system lens, adjust the focusing ring on the camera lens, on photo-translating system CCD photosensitive imaging device plane, form " focus ", the photosensitive imaging device can become the signal of telecommunication to the optical imagery on the imaging plane, through processing of circuit, the electrical information that formation meets the particular technology requirement is a video signal, and output is for uses such as recording equipment or displays then.Whether the readability of video signal and image level be abundant, whether color rendition is true to nature, except the restriction of the inherent quality factor that is subjected to video camera and camera lens, whether the factor of most critical is adjusted camera lens exactly and subject is focused on the CCD imaging plane accurately, focus is accurate more, the definition of image is just high more, and color rendition is just good more.Otherwise, image blurring unclear, the effect that has just lost real-time reproduction on-the-spot scenery being shot and extracted evidence.Adjust the purpose of camera lens focusing ring, will look for into image focus exactly, the process of focusing is found the process of focus exactly accurately.The focus method of camera lens has three kinds: the one, and fixed focal length, lens focus do not need to adjust less demanding occasions such as (as the QQ Video chats) that this video camera is used in; The 2nd, auto-focus lens costs an arm and a leg, and is difficult for popularizing, if subject moves repeatedly, is difficult to accurately capture focus; The 3rd, according to the scope of subject, distance, average light degree of illuminating and project cost choose reasonable Manual focusing camera lens, the scope of application is extensive, consumption is maximum, but every Manual focusing camera lens must output to the video signal of its picked-up external display, naked eyes watch on the display image whether its focusing ring of clear manual adjustment so that obtain best image effect, but, in case there is not display, camera lens focusing work can't be carried out, when particularly in case of emergency not allowing observation display with environmental condition, camera lens very be found focus accurately, almost be impossible.Moreover even if display is arranged, as disturbed by high light, vision is tired especially easily, finds focus equally very difficult, influences operating efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of camera lens focus acousto-optic indicating device.This device is connected with the vision signal of rig camera, utilize internal machine core that the amplitude and the low-and high-frequency component of vision signal are carried out analyzing and processing, drive the focus state of acousto-optic indicating device prompting rig camera then, the operation commissioning staff according to the focus of prompting manual adjustment rig camera till focusing on fully.
The purpose of this utility model is achieved through the following technical solutions: camera lens focus acousto-optic indicating device, comprise movement and loud speaker in casing, the casing, the casing front plate is provided with and focuses on indicator light and lose burnt indicator light, the side of casing is provided with the video signal input jack, loud speaker, focusing indicator light, the burnt indicator light of mistake are connected with movement respectively with the video signal input jack, movement is handled the vision signal of input, therefrom isolate luminance signal, and from luminance signal, detect specific frequency component, analyzed then, judged.If camera lens is in focus state, loud speaker can send the focusing prompt tone, it is bright to focus on indicator light simultaneously, it is good to represent that current camera lens focuses on, if camera lens loses burnt, it is luminous to lose burnt indicator light, and it is bright that operating personnel can observe a left side burnt indicator light of the mistake bright or right mistake of burnt indicator light, thereby judge that camera lens is in the burnt state of preceding Jiao or back, direction is adjusted in decision in view of the above.
The back side of casing embeds has display screen, front plate to be provided with the indicating image change-over switch, and display screen is connected with movement respectively with the indicating image change-over switch.Display screen is set is in order to adjust the subject field of view angle, realize indication and monitor dual-purposely, improve the debugging operating efficiency.The switching of deixis and function for monitoring is finished by the image transitions button.
The side of casing is provided with earphone jack, and earphone jack is connected with movement.When being in noisy environment or needing hidden environment following time, earphone can be inserted earphone jack and replace loud speaker and listen attentively to the focusing sound.
The burnt indicator light of mistake on the casing front plate has two, and they are positioned at and focus on the indicator light both sides.The effect of losing burnt indicator light is that the current camera lens of alert is in preceding Jiao or the back is burnt.
Display screen is the liquid crystal micro display screen.
Casing is provided with the correction button, is used for the self-correcting of device.
Whether advantage of the present utility model is: can point out camera lens to focus on the acousto-optic mode quickly and accurately, volume is little, in light weight, be easy to carry, one people can finish camera lens and focus on debugging, getting twice the result with half the effort, is the very good camera lens debugging acid of professional and technical personnel and users.
