  • Publication number: 20200387764
    Abstract: In a system, mobile terminal and a reader are communicable with each other. In the mobile terminal, a terminal tilt state is detected by a detecting unit as a terminal environmental state, an information code is generated such that the detected terminal environmental state and predetermined information are recorded in the information code, and the generated information code is displayed on the screen of a display unit. In the reader, a reading surface tilt state corresponding to the terminal environmental state is detected by a detecting unit as a reading surface environmental state. When the reader reads the information code and the detected reading surface environmental state and the detected terminal environmental state show the same environmental state, the read predetermined information is used by a control unit to perform processing based on the predetermined information.

  • Publication number: 20200265256
    Abstract: A device for analyzing a worker's work state, the analysis involving generation of determination data for determining whether worker's manual work is performed in a predetermined work order. This device includes imaging and setting units. The imaging unit images, a work video, a worker's manual working state in which the worker repeatedly performs predetermined work. This predetermined work is performed by repeating a plurality of fundamental work operations by hand. Based on a predetermined motion which is previously set for each of the fundamental work operations, the setting unit sets delimitation information to delimit the work video every fundamental work operation at a timing when the predetermined motion is detected. In the device, a generation unit generates determination data which includes both the imaged work video and the set delimitation information. Based on the determination data, the worker's manual work can be analyzed in various ways.

  • Patent number: 7050086
    Abstract: In an electronic endoscope system including a video scope having a solid-state image sensor that successively produces a frame of red, green, and blue image-pixel signals, a difference value is calculated between a value of each of corresponding central red, green, and blue image-pixel signals and an average of values of circumferential image-pixel signals surrounding the central image-pixel signal. When the respective values of the central red and green image-pixel signals are smaller than the corresponding averages of values, they are decreased in proportion to the absolute values of the corresponding difference values. When the value of the central blue image-pixel signal is smaller than the corresponding average of values, it is increased in proportion to the absolute value of the corresponding difference value.

  • Patent number: 6967673
    Abstract: An electronic endoscope system includes a video scope having a solid-state image sensor for successively producing a frame of color image-pixel signals, and an image-signal processor for producing a color video signal based on the frame of color image-pixel signals. A calculation system calculates a difference value between a value of a central single-color image-pixel signal and an average of values of one selected from single-color image-pixel signals surrounding the central single-color image-pixel signal. A color-balance alteration system alters the value of the central single-color image-pixel signal based on the difference value calculated by the calculation system. A selection system performs the selection of the circumferential image-pixel signals such that the circumferential image-pixel signals to be selected are farther from the central image-pixel signal, as a spatial frequency of an endoscope image to be reproduced based on the color video signals is lower.

  • Patent number: 6879339
    Abstract: An electronic endoscope system with a color-balance alteration system includes a video scope having a CCD image sensor for producing a frame of color image-pixel-signals composed of frames of red, green, and blue image-pixel-signals. In the color-balance alteration system, nine red signals are extracted from the frame of red image-pixel-signals, and the nine signals form a 3×3 matrix including a central signal, and the eight circumferential signals. All four sets of three signals are selected from the nine signals, and each set of three signals is composed of the central signal, and two neighbouring signals aligned with each other such that the central signal lies therebetween. When a signal level of the central signal is smaller than both signal levels of the two circumferential signals with respect to even one set of three signals, the signal level of signal is decreased.

  • Patent number: 6677983
    Abstract: An electronic endoscope includes a processor by which an image captured by an endoscope is displayed on a screen of a monitor. Panel switches, a central processing unit (CPU), a magneto-optic disc and a RAM are mounted in the processor. A keyboard and the monitor are connected to the processor. By operating the panel switches, operation conditions of the devices, mounted in the processor or connected to the processor, are set. The set values, which are set by the panel switches or the keyboard, are temporarily stored in the RAM. The set values stored in the RAM are recorded in the magneto-optic disc at every regular time interval. When character information displayed on the screen of the monitor is renewed by operating the keyboard, the renewed character information is recorded in the magneto-optic disc.

  • Patent number: 6663561
    Abstract: A light transmitting part is formed on a second rotary shutter to intermittently transmit excitation light emitted from an excitation light source, which has a circumferential length substantially equal to a half of the entire periphery of the second rotary shutter in order to extend the period during which excitation light is emitted through a light distribution lens. As a living tissue is irradiated with excitation light, it generates autofluorescence. Although the autofluorescence is weak, a CCD can convert the image of the object under examination formed from the autofluorescence into a fluorescence video signal of a sufficient intensity level because excitation light is irradiated for an extended period of time. The obtained fluorescence video signal does not need to be amplified to an undesirable extent and hence can be processed with a high S/N to provide an appropriate diagnostic video signal that is free from noise.
