What is the sensor size of the Canon SX20?
The Canon PowerShot SX20 IS is a digital camera that has a 1/2.3-inch sensor at its core. This imager measures 6.17mm in width and 4.55mm in height, so that the total imaging area of the sensor amounts to 28 mm2.
The SX20 provides an image resolution of 12 megapixels, based on 4 000 horizontal pixels and 3 000 vertical pixels.
Sensor size comparison with a film slide
The sensor diagonal measures 7.7mm, which gives rise to a format factor (or crop factor) of 5.6. Hence, the Canon SX20 is a crop-sensor camera, as its sensor is smaller than a traditional 35mm film slide or negative.
Sensor specs and performance
The table below compares the sensor specs of the Canon SX20 to those of several similar cameras. The reported DXO values are indicators of the sensor's imaging quality (higher is better), covering color depth (DXO Portrait), dynamic range (DXO Landscape), and high-ISO noise (DXO Sports). Larger sensor cameras tend to outperform cameras of the same generation that are equipped with a smaller imager. On the other hand, larger sensors are more expensive and require bigger and heavier lenses than smaller light receptors.
