Description
The present invention relates to a kind of stunt signal (special effect) processing unit and method thereof, particularly a kind of devices and methods therefor that is used for handling the stunt signal according to the regeneration signal of video signal.
A kind of like this digital zoom that is used for realizing is for example arranged, mosaic (mosaic), and the device of stunt signal such as black, white conversion pass through under the camera record after the photographed data at Video Camera, photographed data is carried out the stunt signal processing, and it is recorded on a kind of recording medium.When the data of Video Camera regenerative recording, the data of record are regenerated same as before, and are presented on the screen.
Come to this a kind of block diagram of habitual special effects processing apparatus of Fig. 1, under logging mode (REC), the view data of photography is provided for signal processor 104 by a charge-coupled device (CCD) 102.Discern about the input of the keyboard of stunt signal with microcomputer 108, stunt signal processor 106 carries out the stunt signal processing according to the stunt signal control data that microcomputer 108 provides to the signal of handling through camera processor 104.
Image output interface (I/F) 110 will offer video signal preprocessor 112 through the data of stunt signal processing, and output is through the data of stunt signal processing, be used for checking the photography state of suitable signal of video signal, so that export to an image display device, monitor for example, 112 pairs of data through the stunt signal processing of video signal preprocessor are carried out compressed encoding, and coded data is recorded in the data storage 114.
Under replay mode, the data of the process stunt signal processing of regeneration are decoded by video signal preprocessor 112 from data storage 114, finally the picture signal of storing by image output I/F 110 outputs.
Yet, in being used for writing down and regenerating habitual special effects processing apparatus through the data of stunt signal processing, because the stunt signal processing function at first carries out, the data of just regenerating then, this stunt signal processing mode can cause loss of data.Thereby can't recover original image, and poor image quality.
In order to address the above problem, the purpose of this invention is to provide a kind of device, be used in recording process chronophotography data and about a kind of sub-code data of stunt signal, and in regenerative process, detect sub-code data, and handle stunt signal about a reproduced picture signal according to detected sub-code data.
Another object of the present invention provides a kind of method, be used in recording process chronophotography data and about a kind of sub-code data of stunt signal, and in regenerative process, detect sub-code data, and handle stunt signal about a reproduced picture signal according to detected sub-code data.
In order to realize first purpose, the invention provides and a kind ofly be used for writing down and the special effects processing apparatus of the photographs signal of regenerating, this device comprises a video signal preprocessor, be used under logging mode chronophotography picture signal and about a kind of sub-code data of stunt signal, and under replay mode, be used for the picture signal of regenerative recording, the picture signal of regeneration is provided, and detects sub-code data; A controller, be used for discerning stunt semiotic function pattern, generation is about the sub-code data of stunt signal, and provide a kind of stunt signal control signal according to the sub-code data that detects, and a stunt signal processor, be used for handling a kind of stunt signal about the reproduced picture signal according to the stunt signal control signal.
In order to realize second purpose, the invention provides and a kind ofly be used for writing down and the stunt signal processing method of the photographs signal of regenerating, this method may further comprise the steps: (a) chronophotography picture signal and about the sub-code data of stunt signal under logging mode, and (b) detect sub-code data, and handle stunt signal about the reproduced picture signal according to the sub-code data that detects about the stunt signal.
Can further be familiar with of the present invention above-mentioned purpose and advantage thereof with reference to accompanying drawing to the detailed description of most preferred embodiment by following, in the accompanying drawings:
Fig. 1 is a kind of block diagram of habitual special effects processing apparatus; And
Fig. 2 is the block diagram according to the special effects processing apparatus of one embodiment of the present of invention.
Most preferred embodiment according to a kind of special effects processing apparatus of the present invention and method thereof below will be described.
Fig. 2 is the block diagram according to the special effects processing apparatus of one embodiment of the invention, and in Fig. 2, the view data of photographing with CCD 202 is provided for a camera processor 204 under logging mode REC.Image output I/F 206 will offer video signal preprocessor 208 and stunt signal processor 210 through the view data that camera processor 204 is handled.At this moment, stunt signal processor 210 receives the stunt signal control data according to the input of a trick play functionality key that is set by the user from microcomputer 216, so that check photography state, the view data of handling in the camera processor 204 is carried out relevant stunt semiotic function, and output is through the signal of stunt signal processing.
Video signal preprocessor 208 carries out compressed encoding according to predetermined compression coding scheme to the photographic image data that image output I/F 206 provides, and the image encoded data are recorded in the data storage 214.At this moment, coded image data and the sub-code data about the stunt signal that provided by the microcomputer 212 that receives the input of stunt semiotic function key are recorded in the data storage 214.
Under replay mode PB, recover the view data of regeneration from data storage 214 with video signal preprocessor 208, data recovered is outputed to image output I/F 206, detect sub-code data, and sub-code data is offered microcomputer 212 about the stunt signal.
I/F 206 offers stunt signal processor 210 to the image restored data by image output.By microcomputer 212 discern with respect to the image restored Data Detection to the sub-code data about the stunt signal, the stunt signal control data that stunt signal processor 210 provides according to microcomputer 212 is carried out a kind of stunt signal, and the stunt signal control data is exported as final picture signal.
Yet in shooting process, if the user wants to carry out a kind of new stunt semiotic function by cancelling or revise the stunt signal mode, an ON/OFF key assignments that just can utilize the recording of trick signal mode is to " shut " mode".Microcomputer 212 identifies " shut " mode", the corresponding stunt signal mode of the sub-code data about detected stunt signal that provides with video signal preprocessor 208 is provided, and is not provided the stunt signal control data to stunt signal processor 210.At this moment, stunt signal processor 210 will be exported the original image of a kind of recovery of not passing through the stunt signal processing.
When the user one of the stunt signal mode of record be in " shut " mode" time input during about a kind of key of new stunt signal, microcomputer 212 just provides stunt signal control data about this new stunt signal to stunt signal processor 210.At this moment, the reproduced picture signal of the recovery that stunt signal processor 210 just provides at image output I/F206 is carried out a kind of new stunt semiotic function, and exports new stunt signal pattern.The input of new stunt signal is not necessarily leaveed no choice but carry out under the pent pattern of stunt signal mode of record.When utilizing software to finish the stunt signal processing, can change its input mode.
Utilize the present invention can recover original image, can not lose view data, because the stunt semiotic function is carried out at the reproduced picture signal.So just can improve picture quality, and can cancel or revise the stunt semiotic function, thereby provide various functions for the user.
