Description

The multimedia video show stand

Technical field

The utility model relates to a kind of electronic teaching demonstration instrument, particularly a kind of video showing platform.

Background technology

Existing video showing platform mainly is made up of camera and digital processing circuit thereof, mould process, control panel, is mainly used in school instruction, meeting demonstration and various lectures etc.Usually adopt advanced CCD camera and digital processing circuit so that image stabilization, clear, color rendition is best, camera is installed on the support bar that workbench one side can swing; Control panel is positioned on the side of workbench, realize target to display amplified dwindle, the control of function such as positive negative film counter-rotating, also be provided with the multiple signals input/output port on the workbench; The workbench both sides is provided with rotating arm lamp, shows required light for workbench provides.The deficiency that this class video showing platform exists is: one, signals such as existing literal, picture, material object, film can only be shown function singleness by display devices such as multimedia projector or television sets; Two, cost an arm and a leg, be unfavorable for popularization and application.

The utility model content

The utility model aims to provide a kind of simple to operate, cost is low, function is many multimedia video show stand.

The technical scheme that the utility model adopted is: the multimedia video show stand comprises camera and camera bracing or strutting arrangement, the camera bracing or strutting arrangement is by base, support bar and the camera mount pad of being located at support bar top are formed, be provided with commutator transformer in the base, it is characterized in that: video showing platform also comprises the VCD machine, the support bar of camera bracing or strutting arrangement is made up of two telescopic metal pull bars, base is fixed on the end face of VCD machine, what camera adopted is the colored camera chip of single chip CMOS, the power positive cathode of camera joins with the top of two metal pull bars respectively, the output of commutator transformer joins with the end of two metal pull bars respectively, and input is connected with power supply.

Described base is made up of chassis and spin stand platform, and spin stand platform and chassis flexibly connect, and spin stand platform can be done 360 ° relative to the chassis and rotate.

Described multimedia video show stand also comprises the one side mirror that can rotate up and down, and mirror is installed on the end face with the VCD machine of camera bracing or strutting arrangement homonymy.

Be embedded with a backlight on the described VCD machine end face.

The video output cable of described camera welds mutually with the radio frequency or the video output terminals of VCD machine.

The beneficial effects of the utility model are: the colored camera chip of the single chip CMOS that, adopts the is integrated repertoire of simulation composite video signal output video camera, the integrated level height, indexs such as its color rendition degree, dynamic range, sensitivity, resolution, anti-smear all meet or exceed the level of CCD camera chip, and volume ratio CCD camera chip little a lot, power consumption is lower, price is more cheap, reliability is high, therefore the colored veneer camera definition height of making, volume is small and exquisite, cost is low; Though this camera does not have autozoom and focus function, owing to adopt support bar and the power line of two telescopic metal pull bars as camera; The pressure-raising that as required metal pull bar stretched during use, the camera lens of rotating camera just can reach the purpose of zoom and focusing easily simultaneously; These devices have all dwindled the volume of complete machine greatly, are convenient for carrying, and cost is low, and is simple to operate; Two, with VCD machine and the miniature veneer camera combination of colored high definition, the table top of VCD machine is as the workbench of showing, make complete machine both can show ready-made picture, material object, again can playing video, animation, song, high definition still picture, also possess and sing record function again, realize a tractor serves several purposes, easy to use; Three, just can observe display effect easily with the picture on the specularly reflected display device that simultaneously can rotate up and down, thereby carry out zoom and focusing operation in real time, guarantee the quality of display frame.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.
