This camera has a resolution of 1280×1024 pixels. It uses a CMOS sensor whose pixels are only a little smaller than those in the ToUcam. It is sometimes referred to as a high-resolution camera, but it really isn't. It achieves the larger apparent resolution by using a larger sensor, so it sees a larger area of, for example, the Moon, but the picture is not of a higher resolution than the ToUcam. (I know little of the way that these sensors are made, but I think it is true that the CMOS sensor has a transistor on the chip next to each sensor pixel. So each pixel has to be a little smaller than the corresponding pixel on a CCD chip. This is partly why the CMOS sensor is less sensitive than the CCD.) |
