Abstract: Disclosed are a distance image acquisition apparatus and a distance image acquisition method capable of acquiring a distance image with satisfactory accuracy based on a first pattern projected from a host apparatus even in a case where patterns of structured light having the same shape are projected simultaneously from the host apparatus and another apparatus. A distance image acquisition apparatus (10) includes a projection unit (12) which projects a pattern of structured light, a light modulation unit (22) which modulates a switching timing of projection and non-projection of the pattern with a code, an imaging unit (14) which is provided in parallel with and apart from the projection unit (12) by a baseline length, performs imaging in synchronization with a projection period and a non-projection period of the pattern, and generates a first captured image captured in the projection period of the pattern and a second captured image captured in the non-projection period of the pattern, a differential image generation unit (20D) which generates a differential image of the first captured image and the second captured image, a pattern extraction unit (20A) which extracts the pattern from the differential image, and a distance image acquisition unit (20B) which acquires a distance image indicating a distance of a subject within a distance measurement region based on the pattern extracted by the pattern extraction unit (20A).

Abstract: Upon input of a synchronization signal, which indicates a start of an X-ray emission, from a source control unit for controlling an X-ray source, an electronic cassette makes an FPD start an accumulation operation and measurement of an X-ray dose. The electronic cassette and a console command their communicators to stop communication of any signal other than a stop signal, which stops the X-ray emission from the X-ray source, during the accumulation operation of the FPD. As soon as the X-ray dose has reached a predetermined threshold value, the electronic cassette transmits the stop signal to the source control unit through the console. A delay in transmission of the stop signal due to communication congestion or signal collision does not occur, because the electronic cassette and the console stop the communication of the signal other than the stop signal.
Abstract translation: 当从用于控制X射线源的源控制单元输入表示X射线发射开始的同步信号时，电子盒使FPD开始累积操作和X射线剂量的测量。 电子盒式磁带和控制台命令它们的通信器在FPD的累积操作期间停止除停止信号之外的任何信号的通信，停止X射线源的X射线发射。 一旦X射线剂量达到预定阈值，电子盒通过控制台将停止信号发送到源控制单元。 由于电子盒式磁带和控制台停止除了停止信号之外的信号的通信，不会发生由于通信拥塞或信号冲突而导致的停止信号的发送延迟。
