摄像头传感器的尺寸，一般主要是指对角线的尺寸，先上图，

1.1英寸——靶面尺寸为宽14\*高10.5mm，对角线17mm

1英寸 ——靶面尺寸为宽12.7mm\*高9.6mm，对角线16mm

2/3英寸——靶面尺寸为宽8.8mm\*高6.6mm，对角线11mm

1/1.8英寸——靶面尺寸为宽7.2mm\*高5.4mm，对角线9mm

1/2英寸——靶面尺寸为宽6.4mm\*高4.8mm，对角线8mm

1/3英寸——靶面尺寸为宽4.8mm\*高3.6mm，对角线6mm

1/4英寸——靶面尺寸为宽3.2mm\*高2.4mm，对角线4mm

现在，随着CMOS/CCD集成度的提高，1/2‘’，1/2.5'', 1/3''等在摄像头领域0已经非常常见了。

这个东西现在已经完全是历史遗留产物，据说这个尺寸的术语来自古老的Vidicon真空管(vacuum tubes)图像传送传感器；名称与具体尺寸关系其实不是很密切，大部分都维护了4:3 (Horizontal: Vertical) 宽高比。
