I have a camera with these specs Image sensor = 1/4' OV CMOS Sensor Image Resolution: 1280*1024,640*480,320*240,160*120 Focal Length: 2.8mm Angle of view: 120
Since it's a 1/4 CMOS i got the width and heigth from here: http://www.photoreview.com.au/tips/buying/unravelling-sensor-sizes
I calculated the horizontal and vertical angle of view and they give me
65 and 51 respectively.
Then why does it say in the specs that the angle of view is 120? Am I doing something wrong? Help Please.
