  • Publication number: 20210077051
    Abstract: A radiographic image capturing system is described. If a hardware processor determines that an image processor and an image analyzing unit are capable of sharing image data via an identical memory, the image processor stores image data in the memory and the image analyzing unit analyzes the image data with reference to the memory. If the hardware processor determines that the image processor and the image analyzing unit can send and receive the data via a wired network, the image processor transfers the data to the image analyzing unit, and the image analyzing unit analyzes the data. If the hardware processor determines that the image processor and the image analyzing unit can send and receive the data via a wireless network, the image processor compresses the data or decimates partial data and transfers the data to the image analyzing unit, and the image analyzing unit decompresses and analyzes the data.
