I would greatly appreciate your comments regarding the following:
What upscale SLR cameras utilize user-activated (or automatically selected) visual indicators within the scene area of the viewfinder, superimposed over the image of the subject? For example, the Canon EOS series has a series of autofocus areas in the center of the focusing screen that are black rectangles until one, or more, is/are selected, at which time it/they become illuminated in red.
I think certain Nikon models do a similar thing.
The point is, I have reason to believe that cameras that have this feature infringe upon one of my patents. I have already reached a satisfactory settlement with one major Japanese camera corporation regarding active viewfinder indicia and would like to pursue the rest of the bunch.
Thanx, up front, for your comments.
Special Request For Information.
