Abstract

The invention provides a videoing unit. The videoing unit is characterized in that an oblique planar beam splitter is behind a diaphragm. The beam splitter which is black admits no visible light but infrared light. A second CCD image sensor is disposed on one of two light paths divided by the beam splitter; a first CCD image sensor is disposed on the path reflected by the beam splitter. The first and second CCD image sensors correspond to a first memory disk and a second memory disk respectively. The videoing unit is simple in structure and low in cost, and is convenient for meeting the hardware requirements proposed by the inventor, including the videoing method and automatic video size adjustment.

Description

A kind of video production equipment

Technical field

The present invention relates to field of video processing, especially, relate to the production of video and the broadcast field of video.

Background technology

At present, the kind of multimedia equipment is very abundant, for video equipment, exist multiple different specification, and topmost video equipment screen roughly has two classes, and a class is Fang Ping, and another kind of is widescreen, and just length-width ratio is respectively the screen of 4:3 and 16:9.

On the other hand, during video, consider the production difficulty in production, generally can only produce a kind of video of aspect ratio of the picture example, namely or produce into 4:3, or produce into 16:9's; This just exists such problem, if the video of 4:3 ratio is play in widescreen, then the picture personage all can vertically be flattened, and becomes the pyknic, greatly reduces sight; And if the video of 16:9 ratio is play at Fang Ping, then the picture personage all can laterally be squeezed into thin monkey again, has reduced sight equally.

For aforesaid problem, present solution is manually to adjust the aspect ratio of display, and because this function is not common function, hiding darker in the display setup menu usually, most of people slack off in adjustment, and for some friends person in middle and old age, then can not adjust.

Given this, relatively the method for hommization is, whether display device is identified the personage automatically and be out of shape, if be out of shape, then correspondingly adjusts the picture displaying ratio; But, under present technology, the humanoid identification of this kind is very difficult, because for machine, in the same painting face, do not have fairly obvious color character difference between the humanoid and background, humanoid as identifying, then must sample to each block of pixels in the picture, analyze by numerous and jumbled algorithm then, this can't realize for the relatively poor display device of computing capabilitys such as general television set at all.

At the problems referred to above, the applicant has proposed a kind of video production method and video size automatic adjusting method, and they cooperatively interact, and can realize the automatic adjustment of video pictures ratio like a cork, thereby ensures the appreciation effect of video.

For described video production method, its technical scheme is: at first by photographic equipment photographic picture is carried out infrared light filling; To be divided into two-way from the light that a photographic aperture enters then, the first via directly acts on first ccd image sensor, and second Reuter acts on second ccd image sensor after crossing a visible light optical filtering; Obtain one group of production picture respectively by described first ccd image sensor, second ccd image sensor, be respectively and view and admire picture and infrared picture.

For described video size automatic adjusting method, its technical scheme is: at first the screen proportion with current display device presents video playback apparatus on the backstage with described infrared picture, and by the Aspect Ratio to the profile of the infrared region in the picture, judge whether human body is out of shape, normal as Aspect Ratio, then the described picture of viewing and admiring is not presented at screen with not adding adjustment; If Aspect Ratio is undesired, then will present at screen after the described length and width dimension scale adjustment of viewing and admiring picture.

And the realization of described video production method then needs the video of design specialized to produce equipment, and structure is more simple, and cost is more low more good.

Summary of the invention

At the problems referred to above, the object of the present invention is to provide a kind of video production equipment; The technical scheme of described video production equipment is: this video production equipment comprises aperture, and described aperture rear has a tilting plane beam splitter, and described spectroscope is black, intercepts visible light and sees through infrared light; On the twice light path that is divided into by described spectroscope, see through spectroscopical second ccd image sensor that arranges on the way; By spectroscope reflection first ccd image sensor is set on the way; Described first, second ccd image sensor corresponds respectively to first memory disc, second memory disc.

As preferably, the axis of plane, described spectroscope place and described aperture is 45; Described first, second ccd image sensor is about the plane symmetry at described spectroscope place.

As preferably, between described spectroscope and described first ccd image sensor infrared light filter is set also, be used for the filtering infrared light, to improve the production effect of described first ccd image sensor as much as possible.

Beneficial effect of the present invention is: by this video equipment is set, after picture and infrared picture are viewed and admired in picked-up simultaneously, because in the infrared picture, only have only human body or animal body (all being human body generally speaking) to present tangible infrared region, and the color of infrared region and background difference are fairly obvious, therefore, display device can be distinguished out human body contour outline by color lump easily, and measure the Aspect Ratio of human body contour outline under the current screen ratio, behind the Aspect Ratio of measuring a plurality of human body contour outlines, can confirm whether to exist the picture distortion; Then, can determine whether carry out adjusted size to viewing and admiring picture, when ensureing that it is presented on the screen, have good appreciation effect.

Description of drawings

Fig. 1 is among the present invention, an embodiment schematic diagram of video production equipment.

Embodiment

The present invention is further described below in conjunction with drawings and Examples:

In the embodiment shown in fig. 1, this video production equipment comprises aperture 1, and described aperture 1 rear has a tilting plane beam splitter 2, and the axis of this spectroscope plane, 2 place and described aperture 1 is 45, described spectroscope 2 is black, intercepts visible light and sees through infrared light; Penetrate next light from aperture 1, divided on spectroscope 2 planes and make two-way, the one tunnel acts on first ccd image sensor 31 by an infrared light filter 5 again after the minute surface reflection; The surplus infrared light of spectroscope 2 back filters is crossed by another Reuter, acts on second ccd image sensor 32; Described first, second imageing sensor 31,32 corresponds respectively to first memory disc 41, second memory disc 42.

The present invention is simple in structure, cost is lower, can satisfy video production method and the required hsrdware requirements of video size automatic adjusting method that the applicant proposes simultaneously easily.
