Sensor size / Pixel size

Sensor size is the size of the sensor inside a camera
Pixel size is the size of image sensor that compose image sensor
Sensor size = Pixel size (V) or (H) x Effective Pixel amount (V) or (H)
ex) Pixel size: 4.4μm x 4.4μm
Effective Pixel amount : 1600 x 1200
Sensor size (H) ＝ 0.0044 x 1200＝ 5.28mm
Sensor size (V) ＝ 0.0044 x 1600＝ 7.04mm
Sensor size＝ 7.04 x 5.28mm
