传感器尺寸、像素、DPI分辨率、英寸、毫米的关系
2022-07-01 17:47:00 【全栈程序员站长】
大家好,又见面了,我是你们的朋友全栈君。
虽然网上有很多这种资料,但是太过于复杂,每个人的说法都不一样,看的让人云里雾里的,我总结了一下,不知道对不对!
1. 1英寸=25.4mm
2. 传感器尺寸:传感器的尺寸是指传感器的大小,一般描述大小有两种形式,以IMX386感光元件为例,其传感器尺寸1/2.9英寸,是指传感器对角线为1/2.9英寸;还可以描述成传感器尺寸4.97mm×6.2mm,是指水平(竖直)长(宽)为4.97(6.2)mm。
两种表示方法可以通过下图转换
3. 像素:是指图片的大小, 以小米Max2手机为例,其后置相机像素为4000×3000(12M),是指其拍摄的照片水平(竖直)方向上有4000(3000)个像素,如上图。
4. DPI:每英寸的像素个数,也就是所谓的分辨率。以小米Max2手机后置摄像头为例,其照片DPI为72像素/英寸,可以从其属性里面观察。如下图:
公式:图像的横向(竖向)像素数=打印横向(竖向)分辨率(DPI)×打印的横向(竖向)尺寸
下面是我用小米Max2拍摄的照片
其属性截图如下:
计算器照片的物理尺寸:
图像的横向(竖向)像素数=打印横向(竖向)分辨率(DPI)×打印的横向(竖向)尺寸
3000/72=41.67英寸
4000/72=55.56英寸
我们可以打开PS,打开PS刻度,将其单位调整为英寸,截图如下:
结果是一样的,之所以有细微的差别,是应为在计算I的时候会有一个四舍五入的过程。
