AMIS-710409-A4: 400dpi CIS Module

Data Sheet

The graph in figure 3 depicts the working depth of focus. Since this module is a 400dpi module, a pixel density of 400 pixels per inch,

the MTF was measured with a 200dpi or a 100 line-pair per inch optical bar pattern. The test was conducted with the pixel rate set to

2.5MHz (see Figure 3).

The effective algorithm used in the measurements is as described by the following equation:

MTF={[Vp(n)+Vp(n+1)]/2-[Vp(n+2)+Vp(n+3)]/2}/{[Vp(n)+Vp(n+1)]/2+[Vp(n+2)+Vp(n+3)]/2}
