Part Number: DLP4500
I have been operating the DLP4500 in video mode for an experiment. In short, it projects whatever display the lightcrafter has been connected to through the HDMI port.
The question is about how the projector projects. Does it update the projection by raster scanning (similar to a TV display) ? Or does it does it use some other scheme to update the projection?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Kyle Rakos:
Is there any mode where I can make the update (flipping of the mirrors) in a raster fashion rather than flipping all at once?
In reply to Ashish Rao:
I have a sensor which is able to detect fast moving objects. I am trying to get a dot to move over some area in a raster fashion really fast (need to complete a row in a few microseconds). Suppose I had a raster update scheme, projecting a white image onto the object would have achieved the same.
An alternative to this is to generate a video of a dot moving in a raster pattern in OpenCV or some framework. However, since the projector merely displays the screen and the refresh rate of screens are usually 60Hz, the max achievable speed would get locked onto the refresh rate of the screen. In other words, I could go only upto a 60FPS video of a dot moving in a raster fashion(when the refresh rate of the display is 60hz). This would be extremely slow (would take 4.5 minutes, compared to 1/60 secs in a raster update scheme). Being able to change the update scheme at the hardware level would allow me to achieve extremely high speeds
Hello Kyle, Yeah I do have the Lightcrafter4500 and the GUI. I think the lightcrafter flash memory can't store 260x346 images because that's how many pixels I need to project over. I would need to run a loop of the pixel at different locations in the image to simulate raster scanning. Please correct me if I am wrong.
Thanks & Regards,Hirak.
