Other Parts Discussed in Thread: DLP4500, DLPC350
I have 17 blank pictures which go from black to white. When I try to form pattern sequence on the DLP4500 GUI, I project each picture with 8-bit green plane, 8-bit red plane, 8-bit blue plane. And therefore the projector should project 17*3 = 51 times. Starting from a gray scale point of 0, each time it projects the grey scale point of the picture should increase 5; and when it reaches to the 51th picture the grey scale point should be 255.
In that sense, if we imagine a plot of grey scale point vs. # of pictures, it should show a positive linear line. However, things did not happen as expected. Below is what I found:
When we project 51 pictures, when it reaches the 27th time, the gray scale point of the picture drops down to 0 and starts to increase again from 0 gray scale point. This is not expected because the gray scale point should be continuously increasing, meaning at the 27th time it should increase 5 gray scale point in addition to the 26th's gray scale point.
I did some experiments and found that if the projector projects 30times, gray scale point drops down to 0 on the 16th time; 25 times will make gray scale point drops to 0 on 14; 20 times will make gray scale point drops to 0 on 11; 15 times will make gray scale point drops to 0 on 9; 10 times will make gray scale point drops to 0 on 6; 6 times will make gray scale point drops to 0 on 4; 4 times will make gray scale point drops to 0 on 3........
Why is this and how could I solve it? I would really appreciate if you can take time to look into this problem. Thank you!
