By satisfying the first condition, the brightness of the lens array can be obtained while retaining the long diameter of the first lens surface and the second lens surface in the Y direction, and the resolution of the lens array can be improved by decreasing the lens pitch in the X direction. Moreover, by satisfying the second condition, the MTF at the spatial frequency (line pairs/mm) of the lens array can be definitely set to be greater than 0%. As a result, it is possible to provide the CIS module that includes the lens unit having good optical property with a simple configuration. |
