Patent ID: 8853645

Claim:
A radiographic image detector comprising: a sensor portion including a plurality of pixels, arrayed in a honeycomb pattern, that each generates charges according to irradiated radiation and has a hexagonal shaped pixel region; a detection section, provided for each of the plurality of pixels, each including a pixel electrode that collects the charges, a storage capacitor that accumulates the charges collected by the pixel electrode, and a first switching element and a second switching element that read out the charges accumulated in the storage capacitor; a plurality of first scan lines that are disposed one for each of a plurality of pixel rows and that are each connected to control terminals of the first switching elements in the corresponding pixel row; a plurality of second scan lines that are disposed one for each of respective pairs of the plurality of pixel rows that are adjacent to each other in a column direction, and that are each connected to control terminals of the second switching elements in the corresponding column direction adjacent pair of pixel rows; a plurality of data lines that are disposed so as to respectively intersect with the plurality of first scan lines and the plurality of second scan lines, the plurality of data lines including, a plurality of first data lines that transmit first charge signals corresponding to a combined charge amount of 3 pixels that are read out by the second switching elements of the 3 pixels mutually adjacent in the respective pairs of column direction mutually adjacent pixel rows, and a plurality of second data lines that transmit second charge signals corresponding to a combined charge amount of 2 pixels that are read out by the second switching element of the 2 specific pixels adjacent to the 3 pixels in the pixel row direction, and transmit third charge signals of 1 pixel that is read out by the first switching element of the 1 specific pixel adjacent to the 2 specific pixels in the pixel column direction; and a plurality of charge amplifiers that are each connected to one end of the plurality of respective data lines, the plurality of charge amplifiers including, a plurality of first charge amplifiers that convert the first charge signals into voltage signals during a first period and a plurality of second charge amplifiers that sum the second charge signals and the third charge signals together and convert the sum into voltage signals during a second period.
