Abstract: In a wireless communication terminal, a processor is configured to execute sleep determination when a wireless communicator receives a sleep-declaration packet from a sleep-declaration terminal. The processor is configured to determine that sleep by the sleep-declaration terminal is accepted if an upper-rank terminal in a wake-up state other than the sleep-declaration terminal is present. The processor is configured to determine that the sleep by the sleep-declaration terminal is not accepted in the first sleep determination if the upper-rank terminal in the wake-up state other than the sleep-declaration terminal is not present. The processor is configured to cause the wireless communicator to transmit a sleep-prohibition packet to the sleep-declaration terminal when the processor determines that the sleep by the sleep-declaration terminal is not accepted.
Abstract: In a light source apparatus for endoscope, when a light-emission amount of a second light source is less than or equal to a predetermined light-emission amount, a light source control circuit performs a first light-emission amount control of changing the light-emission amounts of the first to third light sources so as to allow a color balance to be maintained at a predetermined color balance. When the light-emission amount of the second light source is greater than the predetermined light-emission amount, the light source control circuit performs a second light-emission amount control of changing the light-emission amount of the third light source by a method different from the first light-emission amount control while changing the light-emission amounts of the first and second light sources by the same method as the first light-emission amount control so as to allow the color balance to be different from the predetermined color balance.

A processor refers to a reference model indicating a figure expanding two-dimensionally or three-dimensionally in a three-dimensional space including two or more points and determines whether or not a positional relationship between each of the two or more points and the reference model meets a condition that is set in advance in the determination step. The processor generates an image and differentiates a display state of a pixel corresponding to a first point from a display state of a pixel corresponding to a second point in the generation step. The first point meets the condition, and the second point does not meet the condition. The processor displays the image on a display in the display step.

Abstract: In a measurement device, an image acquisition unit acquires a first image generated by imaging an object to be measured in a first imaging state and acquires one or more second images generated by imaging the object in one or more second imaging states. A specified point setting unit sets a specified point on the first image. A three-dimensional (3D) shape restoration unit restores a 3D shape of the object by using a plurality of images including the second image determined to include a point corresponding to the specified point. A reference dimension setting unit sets a reference dimension on the first image or the 3D shape. A measurement unit measures the object on the basis of the 3D shape, the specified point, and the reference dimension.
