SOLID-STATE IMAGING DEVICE, X-RAY IMAGING SYSTEM, AND SOLID-STATE IMAGING DEVICE DRIVING METHOD

摘要

This solid-state imaging device is equipped with: a light-receiving unit (10) wherein M x N pixels are two-dimensionally arranged in M rows and N columns; an output unit that outputs a digital value generated on the basis of the amounts of electric charges input from these pixels; and a control unit. The control unit groups the M x N pixels of the light-receiving unit into unit areas each comprising Q rows and R columns, groups the unit areas two-dimensionally arranged in M/Q rows and N/R columns into binning areas each comprising K rows and one column, and causes the output unit to sequentially output per row the digital values of the binning areas two-dimensionally arranged in M/KQ rows and N/R columns, repeating this process K-times in column sequence, each digital value corresponding to the total of electric charges output from the K x Q x R pixels included in a respective binning area. This configuration allows for a solid-state imaging device capable of outputting a signal that is easy to handle even when binning is applied.
