1. A two-dimensional incident position detector device for radiation comprising:
- (a) a detector array including a plurality of detection cells in two-dimension arrangement;
(b) comparator means for comparing an output from a noticed detection cell among said detection cells with outputs from all other detection cells adjacent to said noticed cell; and
(c) incident position determining means for determining a position of said noticed cell as an incident position of radiation when the output from said noticed cell is larger than the outputs from all adjacent detection cells.

Abstract
A two-dimensional incident position detector device for radiation, the device comprising a detector array including a plurality of detection cells in two-dimensional arrangement, and a comparator circuit for comparing an output from a noticed detection cell with outputs from all detection cells adjacent to said noticed cell, whereby a position of the noticed cell is decided as an incident position of light or radiation when the output from the noticed cell is larger than the outputs from all adjacent detection cells.
