According to embodiments of the present invention, a semiconductor photomultiplier device is provided. The device consists of crossed diodes which are mounted in the device and will connect to the readers. Second pixel information corresponding to a second image is received from a second imager. A second doped region and a third doped region are in the first well, respectively having the first and second conductive types. As a result, the resin fixture can suppress a transfer of heat generated in the electronic circuit board to the semiconductor element module.
