  • Publication number: 20150279196
    Abstract: A first data taking section takes first detection results from a first wireless tag reader which detects the come and go of an electronic cassette into and out of a first service zone, and also takes second detection results from a second wireless tag reader which detects the come and go of an electronic cassette into and out of a second service zone. A first alert controller drives a first speaker to start an alert when the first alert controller determines on the basis of the first detection results that the electronic cassette has gone out the first service zone. After the start of alerting, the first alert controller stops driving the first speaker to interrupt the alert when first alert controller determines that the electronic cassette has come in either the first service zone or the second service zone.

  • Patent number: 8626273
    Abstract: White light and excitation light are applied to an internal body part. An electronic endoscope captures a normal image of the internal body part irradiated with the white light, and a special image of autofluorescence emitted from living body tissue of the internal body part irradiated with the excitation light. An object distance detector detects an object distance between a CCD and an inspection area of the internal body part based on the normal image. A binning processing section applies a binning process to the special image. There are two types of binning processes, i.e. an intensity adjustment process and a resolution adjustment process. In the intensity adjustment process, the binning number is increased with increase in the object distance. In the resolution adjustment process, the binning number is decreased with increase in the object distance. Which process to perform is determined by operation on a processing type selector.
