What kind of sensor does iStar use (CCD or CMOS)? iSTAR uses a CMOS sensor. Have more questions? Submit a request Comments Erik Winquist September 11, 2013 11:20 But of what size? The spec sheet doesn't list the sensor size, nor does the EXIF metadata in the images. This makes it a guessing game trying to stitch the four fisheye images together with 3rd party stitching software. Erik Winquist September 11, 2013 11:24 And, by size, I mean the physical width and height dimensions in mm. NCTech Support September 11, 2013 11:51 Hi Erik, I'm afraid we do not publish specifics of our sensors in a public forum. What software are you trying to use to stitch the images? Normally, you only need to know the focal length and crop factor and the software works the rest out for you. These settings are: Lens Type: Circular Fisheye Focal Length: 2.67mm Crop Factor: 5.6 We've a video detailing how to stitch images with these settings using PTGUI here: http://support.nctechimaging.com/entries/23448327 Hope that helps! Erik Winquist September 11, 2013 12:31 Yes, cheers, I found that video very shortly after I'd posted this question.
