(1) First of all, the video Visualizer's power supply (POWEER (I/O)) is turned on, and the light handling changeover switch is placed in the BACK LIGHT ON state, which is when the light at the bottom becomes bright. Switch the signal buttons: (VIDEO IMAGER/ A/V1/A/V2) in the VIDEO IMAGER button down to ensure that the Visualizer output signal is the projection information.
(2) Then put the slide on the carrier, adjust the lens so that it is aligned with the slide, touch the IN or OUT button on the lens with your finger to adjust the magnification of the slide appropriately, so that it is in the clearest state on the screen. If the image on the screen is not placed correctly, you can rotate the slide to make appropriate adjustments. The image direction can also be adjusted by turning the image steering knob on the lens, which is equivalent to rotating the slide. If you intend to use inverse color projection to achieve a special projection effect, you can use your finger to press the NEGA button, then a reverse color image appears on the screen, when the NEGA button is pressed again after the image is back to the original state. The operator can observe the projection effect through the LCD display.
2, physical projection Usually on the display can be shown in kind for the picture or text data and some simple models or teaching aids, etc., its basic projection method and the above transparency film projection method is basically the same, except that the light processing switch is best placed in the ARM LIGHT ON state, and will be displayed on the upper part of the (ARM LIGHT) lamps can be properly Rotate, adjusted to the best angle, in order to increase the light in kind, to enhance the clarity of the projected image.
3, the experimental demonstration First of all, according to the demonstration of the operation of the activity of the space, adjust the tilt angle of the lens arm, the appropriate rotation of the lens and adjust the top of the lens image steering knob, so that the Visualizer is in the best state of projection. The other buttons of the Visualizer are the same as those above and will not be repeated here. It is worth mentioning that, in the experimental demonstration of certain important phenomena or results in the operation process, we can use our fingers to lightly press the FRAME MEMORY for image processing (using its static image function) button to "take a picture", so that the phenomenon or result can be a long time to stay on the screen, as long as the button is pressed again The static image function is canceled, the video Visualizer can continue to be used normally.
4, play audio-visual information At some point we need to use the Visualizer to show video or video discs and other audio-visual programs. We have to be from the VCR output signal input to the video display of a A/V input port, the need for signal switching when we, according to the audio-visual signal input location will be the corresponding switching signal button A/V1 or A/V2 press. Thus the output signal of the Visualizer will be switched to the corresponding audio-visual signal. The result of the screening can be projected on the LCD screen to provide reference to the operator.
