Array dish 4 is connected with the power set that rotate with the conversion teleconverter relative with camera 3 be used to driving array dish 4.Power set comprise that the drive motors be installed in casing reaches the driving-belt by its driving, and driving-belt and array dish are in transmission connection.
As shown in Figures 2 and 3, operation principle of the present invention and flow process are as follows:
Under the television startup state, teleconverter array dish 4 acquiescences are positioned at the teleconverter lens position of 1 times, and camera 3 is with former ratio imaging.When the user presses the zoom button of remote controller, after television set receives remote controller signal, by the TV motherboard transmission of signal to motor control chip, and output control signal, make the corresponding angle of drive motors rotation, thereby the conversion teleconverter 5 relative with camera 3 changes the zoom multiple.
In the present embodiment, control signal is by the realization of PWM square wave, and teleconverter array dish is connected with belt transmission with drive motors, by controlling the direction of PWM waveform, the drive motors forward or reverse, drive the array dish and rotate to switch teleconverter, guarantees that the process of zoom is efficiently moved.
After the teleconverter switching, the image photographed judges whether perfect imaging after by internal image processor ISP, processing, and output control signal after image processor ISP calculates, finely tune the angle of teleconverter, guarantees image quality.By this feedback mechanism, make camera system after zoom can be suitable for the television screen size of different size.Simultaneously, before and after zoom, the image streams of different demonstration multiples retains respectively, processes for rear end ISP image processor, realizes that the distortion edge is eliminated and the function of image sharpening.
After the TV shutdown, the algorithm of internal default can make reset motor, thereby teleconverter array dish is returned to reset condition, i.e. the teleconverter position of 1 times of amplification.
Embodiment bis-:
As shown in Figure 4, in the present embodiment, the card of teleconverter array dish 4 is crosss, and on the array dish, teleconverter 5 is the cross array.
For the power set that drive 4 motions of array dish, comprise: be used to driving the horizontal drive motor of array dish horizontal motion, and be used to driving the vertical drive motors of array dish vertical direction motion, the horizontal drive motor is by the gear of its output and be in transmission connection with the array dish with the horizontal drive link 61 of gear engagement; Vertically drive motors is all by the gear of its output be in transmission connection with the array dish with the vertical drive link 62 of gear engagement.
During teleconverter 5 switching, remote controller sends control signal, after television set receives remote controller signal, to motor control chip, after motor drive ic was received control signal, motor rotated a fixing turn by the TV motherboard transmission of signal, the driven gear motion, the push-and-pull cross array dish of horizontal pull bar 61 or vertical pull bar 62, make teleconverter level or vertically mobile, aligns camera.
Image processing process is with embodiment mono-.
Embodiment tri-:
In the present embodiment, the card of teleconverter array dish is in-line, is equivalent to criss-cross array dish horizontal direction part or vertical direction part, and teleconverter is along array dish bearing of trend linear array.
Power set comprise be used to driving the straight-line drive motors of array dish, and drive motors is in transmission connection by drive link and gear and array dish, drives the array dish and makes the straight line back and forth movement, with the switching teleconverter.
In other embodiments of the invention, the card of described array dish is can also be other horizontal with perpendicular combining forms, for example just put, put upside down, T or the L font of left traverse or right traverse, described teleconverter is T font array, the L font array of placement direction accordingly, does not repeat them here.
The embodiment mono-of take is example, and in conjunction with the flow chart shown in Fig. 5, the Zooming method of intelligent television camera comprises the following steps:
A. television startup state, camera aligns with 1 times distance mirror on teleconverter array dish, the former ratio imaging of camera;
B. TV remote controller is sent zoom signal, and system catches and preserve the zoom prior image frame, and Image Saving is in TV motherboard flash;
C. television receiver receives the signal that remote controller sends, and by the TV motherboard transfer control signal to motor drive ic;
D. motor drive ic outputs control signals to drive motors;
E. drive motors rotates, teleconverter array dish rotates with drive motors, the switching teleconverter, the drive motors chip is received control signal, and calculate the needed number of turns of the teleconverter that turns to corresponding multiplication factor, drive motors rotates a fixing turn, and the camera lens of camera is alignd with corresponding teleconverter, and the switching teleconverter completes;
F. after teleconverter switching, system catches two field picture after zoom by camera, and the image before and after zoom retains respectively, for rear end image processor ISP, to process, realizes the function of the elimination of distortion edge and image sharpening;
G. the image processor ISP of TV inside compares two two field pictures before and after zoom, according to comparative result, calculate the vernier angle variable, and the output fine adjustment signal feeds back to drive motors, drive motors rotates vernier angle, teleconverter array dish is finely tuned thereupon, makes aliging of teleconverter and camera;
H. preserve the image after fine setting, judge the whether perfect imaging of this image, if judgment result is that No, repeat previous step, by this image continue with zoom before image compare; If judged result is Yes, i.e. perfect imaging, continue next step;
I. image processor is judged perfect imaging, the outgoing position locking signal, and zoom completes.
After the TV shutdown, the built-in system default algorithm resets drive motors, thereby makes the teleconverter array return to reset condition.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand, and the present invention is not restricted to the described embodiments, and without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
