F.F. out code processed, the user instruction receiving division 280 respond the user's operation carried out to the fast forward button and first produce F.F.
The F.F. open command is transported to the main control chip 250, the master by open command, the user instruction receiving division 280
Control chip 250 gets F.F. open command and accordingly produces control F.F. open command.The main control chip 250 is by the control
F.F. open command processed is transmitted to described image processing unit 230.Described image processing unit 230 is opened according to the control F.F. to be referred to
Make and recover to handle the video source data in first breakpoint and accelerate image processing speed so that the video source number
According to broadcasting speed accelerate so that enter F.F. state.
When the user instruction receiving division 280 is responded to the user's operation of the fast forward button and produce F.F. out code
When, the F.F. out code is transported to the main control chip 250 by the user instruction receiving division 280.The main control chip
250 produce the control F.F. out code according to the F.F. out code.The main control chip 250 is by the control F.F.
Out code is sent to described image processing unit 230.Described image processing unit 230 is according to the control F.F. out code to institute
State video source data and carry out pause processing, the video source data enters pause broadcast state from second breakpoint.Change sentence
Talk about, the video source data of 200 playback process of projector equipment, the first breakpoint produced by " a key blank screen " is dragged to backward
Second breakpoint.Refer to if the user instruction receiving division 280 responds user and the user's operation of the play button is produced one and played
When making, the play instruction is sent to the main control chip 250 by the user instruction receiving division 280, then the main control chip
250 produce a control play instruction according to the play instruction.The main control chip 250 by it is described control play instruction send to
Described image processing unit 230.Described image processing unit 230 recovers to scheme according to the control play instruction from second breakpoint
As processing so that the projector equipment 200 recovers picture in second breakpoint and plays.
When the projector equipment 200 is in black state, if user's operation play button, the user instruction receiving division
280 response users produce the user's operation of the play button play instruction, and the user instruction receiving division 280 is by the broadcasting
Instruction is sent to the main control chip 250, and the main control chip 250 produces a control play instruction according to the play instruction.
The main control chip 250 sends the control play instruction to described image processing unit 230.Described image processing unit 230 according to
Recover image procossing from first breakpoint according to the control play instruction but still shown without picture.
Projector equipment 100,200 provided by the utility model, when being inconvenient to carry out display picture, user only needs simply to grasp
Make the user's operation portion 170,270, the control of main control chip 150,250 be simply turned off light source 113,213 do not export illuminating bundle and
Without power-off operation, realize " a key blank screen ", so that projector equipment 100,200 enters black state, it is convenient to protect user
It is not easy disclosure.In addition, when needing display picture again, user only needs to carry out the user's operation portion 170,270 simple
Operation, so that it may recover picture and show, it is convenient for users to use.
It is understood that those skilled in the art can also do other changes etc. in the utility model spirit is used in this reality
With new design, without departing from the technique effect of the utility model.These are done according to the utility model spirit
Change, all should be included in the utility model it is claimed within the scope of.
