Abstract
The utility model relates to a vidicon with facial recognition focus function, which is characterized in that a central processing unit of the vidicon is additionally provided with a DSP chip. The utility model has the advantages that the function of facial recognition technology is added on the basis of the original vidicon function, the vidicon can automatically lock the facial position in the picture when making videos, automatically adjusts to take the face of people as the subject of the videos and sets accurate focus and light exposure so as to enable the shot picture to be more vivid and lifelike.
Description
Technical field
The utility model belongs to video camera, relates in particular to a kind of video camera with face recognition focusing function.
Background technology
Relation how to handle the figure and ground in the shooting is technical stronger problem.If the personage is not in the middle of view finder, video camera just may cause the personage on the picture fuzzy focus to a long way off background place; When figure and ground's difference in brightness is very big, then can cause people face under-exposed or excessive again.Therefore, in the shooting process, select the relation of the suitable depth of field, film speed and aperture, especially personage and background all to need through special training.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of video camera with face recognition focusing function, on the basis of original camera function, increased the function of face detection (FaceDetection), can when shooting, more can be clear that face, people's face position in the locking picture, and, focal length and exposure accurately are set automatically with the main body of people's face as shooting, make the picture of shooting more lively.
The utility model for achieving the above object, by the following technical solutions: a kind of video camera with face recognition focusing function is characterized in that: the central processing unit of described video camera is set up dsp chip.
Described dsp chip adopts Samsung DSP7 chip.
The utility model beneficial effect: the function that on the basis of original camera function, has increased face detection, can automatically lock people's face position in the picture at when shooting video camera, and adjust people's face automatically as the main body of taking, focal length and exposure accurately are set, make the picture after the shooting more lively, true to nature.
Description of drawings
Fig. 1 is that circuit of the present utility model connects block diagram;
Fig. 2 is an operational diagram of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in the figure, a kind of video camera with face recognition focusing function, the central processing unit of described video camera is set up dsp chip.Described dsp chip adopts Samsung DSP7 chip.Operation principle: image processing (Image Processing) function that adopts digital signal processing chip.Utilization face recognition (Facedetection) technology, video camera stores in the dsp chip by the characteristic informations such as eyes, mouth of personage in the identification view finder, automatically locks the people's face position in the picture, automatically with the main body of people's face, focal length and exposure accurately are set simultaneously as shooting.When face recognition function was started working, video camera will be automatically be provided with according to the position and the illumination of people's face in the picture, guarantees the clear of people's face and exposure accurately.When in the picture a plurality of personage being arranged, face recognition function also can be selected topmost who object and accurately work.Certainly this technology can be applied on the digital camera equally.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1, a kind of video camera with face recognition focusing function, it is characterized in that: the central processing unit of described video camera is set up dsp chip.
2, the video camera with face recognition focusing function according to claim 1 is characterized in that: described dsp chip adopts Samsung DSP7 chip.
