AutoDetect <strong>Pro</strong>blems<br />
AutoDetect works by being able to discriminate between different color RGB (Red<br />
Green Blue) values and other image values. How well AutoDetect works depends on two<br />
main factors.<br />
1. Display. The more colors your monitor can display, the better PPV is in finding the<br />
right color. You want your display set to the highest value possible. This is usually 24 or 32<br />
bit (true color). You can use 16 bit (64k) if this is the only setting you can use and still maintain<br />
an 800x600 screen resolution. Some display cards reset your screen resolution when<br />
you increase the number of colors being used.<br />
2. Quality of the image. The better the quality of the original image, the better the AutoDetect<br />
mode will work. We re<strong>com</strong>mend using a digital camera with a flash. This seems to<br />
provide the best picture quality and the highest contrast between colors.<br />
What If AutoDetect Just Won't Work?<br />
No problem. Simply redo the exam using the manual mode. PPV effortlessly switches<br />
between manual and auto. You can even perform a manual exam on one image and auto<br />
on the second image.
