In gate intermittently staying, opticator illuminates the frame in frame window, and is amplified by projection lens, is incident upon in screen.
Different screen sizes and screen distance, using the projection lens of different focal length；When projection deformation wide screen film, separately widen screen
Camera lens.Light source also difference due to projector purposes is different, such as incandescent lamp, bromine tungsten filament lamp, xenon lamp.Light source power is high when screen is big.
Playback part: the acoustic information that optics on film or magnetic track record is reduced into tone currents, through sound amplifier
Or loudspeaker is converted into sound.This part is made of exciter bulb, excitation camera lens, light sword, photoelectric tube, vibration absorber or magnetic head.
Some narrow gauge projectors also install erasure and magnetic recording head additional in this part for the ease of voluntarily dubbing.
Body part: being the frame of support and connecting components.Generally to install electrical equipment, conducting wire etc. in rack.
Exterior panel or surface are equipped with instrument, indicator light and Operation switch etc..

The bodily form identifies equipment, connect with the depth of field analytical equipment, for receiving the subgraph to be analyzed, based on described wait divide
The profile for analysing subgraph judges the type of action of corresponding performer, determines corresponding room with the type of action based on the corresponding performer
The movement grade of the interior current presentation content of projector；
Wherein, the bodily form identification equipment when obtaining new movement grade each time, by new movement grade and current action
Grade is compared, when the new movement grade is more than or equal to the current action grade, based on the new movement etc.
Grade updates current action grade, and store-updated current action grade.
4. key frame movement range detection system as claimed in claim 3, it is characterised in that:
The bodily form identification equipment is also used to when the new movement grade is less than the current action grade, keeps current dynamic
It is constant to make grade.
5. key frame movement range detection system as claimed in claim 4, it is characterised in that:
The bodily form identification equipment is also built-in with storage unit, is used for store-updated current action grade.
6. key frame movement range detection system as claimed in claim 5, it is characterised in that:
The second processing equipment is also used to any grid region in the indoor projected images and issues there are when impulse disturbances
There are impulse disturbances information.
7. key frame movement range detection system as claimed in claim 6, it is characterised in that:
In the fourth process equipment, neighborhood territory pixel point is closer apart from pixel to be processed, and it is flat that neighborhood territory pixel point participates in weighting
The weighted value of mean operation is bigger.
8. key frame movement range detection system as claimed in claim 7, it is characterised in that:
The instant picture pick-up device is also used to stop when receiving the non-key frame and judging signal to indoor projector opposite
The instant camera shooting of screening area acts.
9. key frame movement range detection system as claimed in claim 8, which is characterized in that further include:
Indoor timing device judges that equipment is connect with the key frame, when for judging that equipment provides current for the key frame
It carves.
