The invention further discloses a video photographing method. According to the invention, the video photographing process is greatly convenient; a photographed video presents teaching behaviours, such as writing and annotation, of teachers in the face of audiences; written and annotated characters and the like are also on the front; therefore, direct feels of the audiences are improved; interaction between teaching and learning is facilitated; and the good teaching and learning effects are achieved.
Description
Technical field
The present invention relates to instructional video field, particularly relate to a kind of video shoot system and method.
Background technology
Before more than 2500 years, Confucius's apricot altar is given lectures so far, still continues to use more traditional teaching method, and that person that do not give lessons exactly, facing to student, arranges blackboard behind to write confession student carrying out visual understanding the person of giving lessons.
Nowadays, what the progress along with Internet technology brought to education sector advances by leaps and bounds, and the person of giving lessons, with the teaching method of student, snafu change occurs already, and utilize Web-based instruction video technique, teaching method can be crossed over Time and place and be achieved.The content not only person of giving lessons can given lectures is preserved by video record carries out repeatedly playback, can also realize real time remote teaching.Developing rapidly and using of online education and Online Video, greatly facilitates learning aid.Web-based instruction video also becomes student gradually and contacts the most direct of outstanding education resource and topmost means.
But, even if the development of Web-based instruction video so rapidly, in video production recording process, the personnel of giving lessons need in conjunction with various ways such as a large amount of writings on the blackboard, PPT note, improve efficiency of giving lessons, and strengthen the interactive of give lessons Memorability and classroom.But the position due to the person of giving lessons is in the middle of clipboard and filming apparatus, the person of giving lessons carries out writing on the blackboard or while writing note, can turn health, back to participant turning round.In this case, participant can find, the person of giving lessons may block writing on the blackboard, explains, causes the person of giving lessons to need to move frequently.And due to back to the person of giving lessons, teaching efficiency also there will be the situation of decline, give the very large inconvenience that the student of viewing video brings.Student also may because this inconvenience causes diverting one's attention often.
Summary of the invention
In order to overcome the defect that above-mentioned prior art exists, the invention provides a kind of video shoot system and method.Utilize the video that this system and method is shot, the person that realization not only do not given lessons is that front is write, and the content that the person of giving lessons writes on clipboard is also forward display, and namely front is in the face of the viewing personnel of video.
Usually, the equipment that video capture uses is clipboard and camera, and the person of giving lessons stands between camera and clipboard, is taken scene by camera.
We can use transparent clipboard to take, and like this, are then be placed between camera and the person of giving lessons by clipboard.But due to the opposite side of clipboard of standing the person of giving lessons, be contrary through the scene taken by transparent clipboard, the direction that the person of giving lessons such as seen through transparent clipboard writes and the font of writing are anti-.As: the person of giving lessons writes from left to right, and the scene of shooting is then for write from right to left; As the person of giving lessons writes ABCD, then the scene of taking will become
For this reason, one of inventive solution is to provide a kind of video shoot system, comprise transparent wordpad, reflection unit and camera, described reflection unit and described camera are placed on the radial side of transparent wordpad, described reflection unit can reflect the scene of the radial opposite side of transparent wordpad, and the scene in reflection unit can be produced by described camera.
The present invention also provides a kind of video shoot method, comprise the steps: radial side reflection unit and camera being placed on transparent wordpad, the scene of the radial opposite side of reflection unit reflective transparent clipboard, the scene in reflection unit is produced by camera.When video shoot, the radial opposite side that the person of giving lessons stands in transparent wordpad carries out saying actions such as being subject to, write, and the radial opposite side at transparent wordpad then produced by camera and reflection unit.Like this, the contrary scene of the mirror image directly seen through transparent clipboard is after the mirror reflection of reflection unit (including but not limited to such as mirror), and the scene presented in reflection unit becomes normal direction.As: the person of giving lessons writes from left to right, and in taken reflection unit, scene is also from left to right write; As the person of giving lessons writes ABCD, then the scene in taken reflection unit is also ABCD.
As preferably, lighting device can be provided with in described clipboard both lateral sides.
As preferably, illuminating lamp can be provided with in the edge surrounding of described clipboard.Both sides and the edge surrounding of clipboard can arrange lighting device, are preferably LED or fluorescent lamp.
As preferably, at described transparent wordpad, Background apparatus can be set behind.Background apparatus can be the Background apparatus of black or pure dark color, presents a contrast larger with clear glass, is more conducive to the chromaticity improving video.
By arranging Background apparatus behind at clipboard, Background apparatus can be the device that the plate of pure color or curtain etc. are suitable as background, makes the video taking out have better background, improves the quality of video, and the viewing improving video viewers is enjoyed.When making video, also can be arranged to the background of requirement according to personal like, the color of background can be arranged according to the color of the pen write on transparent wordpad, presents a contrast with the color of lettering pen.
By arranging the mode of lighting device or illuminating lamp, object is the plumpness in order to increase or improve light, by arranging or regulate quantity and the light intensity of lighting device or illuminating lamp, can obtain the optimal light brightness of applicable human eye viewing.
Camera preferably uses broadcast level video camera to take, and possesses and exports HD-SDI semiotic function.Such as, model: SonyP1 collocation kxwell Remote The Cloud Terrace.
Preferably, display can also be connected at filming systems, as TV, the professor's picture photographed directly be shown over the display, realize the effect play in real time.
The present invention greatly facilitates video shoot process, the video produced out present teacher front in the face of spectators carry out writing, professor's behavior such as annotation, the word etc. write, annotated also is front, improves the direct feel of spectators, be beneficial to interactive teaching and learning, reach good teaching efficiency.
