--- Comment #2 from Milan Zamazal <[email protected]> --- (In reply to Maik Qualmann from comment #1) > Oh, this will be difficult to understand how Pentax handles it. I don't think it's that difficult. > I'm not clear on what you photographed; it seems to be a screen with the > focus points. Did you draw the focus points? It's a computer screen. I put the camera on a tripod, displayed the focus points in the viewfinder, and drew their positions on the screen while looking through the viewfinder. It's inaccurate but I suppose the pattern is more or less regular, so it should be possible to extract some reasonable coordinates from it. > Pentax only uses a numbering system from 1 to about 33, no coordinates, and > we don't know how they number them. They are numbered 1-33 from top left to right and then down. That is: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 > The reference implementation shows that a distinction must also be made > between phase and contrast focus. Yes. The examples above are for phase focus. The contrast detection pattern consists of a grid of 7x5 rectangles that covers most, but not whole, of the image area. Here are some examples: http://data.zamazal.org/digikam/_K1_6906.JPG ... the central rectangle selected as the focus area and in focus http://data.zamazal.org/digikam/_K1_6907.JPG ... the top left rectangle selected as the focus area and in focus http://data.zamazal.org/digikam/_K1_6909.JPG ... the bottom right rectangle selected as the focus area and in focus http://data.zamazal.org/digikam/_K1_6908.JPG ... the whole focusable area selected and the 2nd and 3rd rectangles from left in the first (top) row and from the second row are in focus I can see some focus area coordinates in exiftool output but not the points in focus. They must be stored somewhere, the camera reports them. -- You are receiving this mail because: You are watching all bug changes.
