Abstract:
PURPOSE: A method and apparatus for detecting a motion picture response property of an image display device are provided to reflect a visual color recognition property to the image display device according to chromaticity change by detecting and applying a response property of a motion picture displayed with colors. CONSTITUTION: A preset picture signal is inputted and displayed(S0). The chromaticity and brightness properties of the displayed picture are measured using a chromaticity brightness meter(S1). Display picture response time of the displayed picture is calculated(S2). A contrast sensitivity function is determined according to the measured chromaticity and brightness properties(S5,S7,S9).

PROBLEM TO BE SOLVED: To allow an operator to reliably and clearly recognize the presence of a lesion part within an observation visual field.SOLUTION: A fluorescence observation device 1 is provided with: an imaging element 19 for acquiring a fluorescence image by imaging fluorescence generated in a subject A by being irradiated with excitation light from an excitation light source 3; a sensitivity adjustment part 23 for setting sensitivity of the imaging element 19 to the fluorescence on the basis of a gradation value of the fluorescence image acquired by the imaging element 19; an extraction part 25 for extracting an area that has a larger gradation value than a prescribed threshold value from the fluorescence image acquired by the imaging element 19 by the sensitivity set by the sensitivity adjustment part 23; a notification part 25 for presenting information indicating the presence of an area extracted by the extraction part 25 to an operator; a display part 7 for displaying the fluorescence image; and a display switching part 24 for causing the display part 7 to display the fluorescence image when the sensitivity set by the sensitivity adjustment part 23 to the imaging element 19 is the predetermined threshold value or lower, and causing the notification part 25 to present information when the sensitivity is greater than the predetermined threshold value.
Abstract:
The present invention relates to a method for monitoring the filling of a capsule with a medicament, to a corresponding filling method, to the associated apparatuses, and to a computer program for controlling the method and the apparatus. In the monitoring method, after at least part of the capsule has been filled with a predefined filling mass of a predefined closed contour of the medicament, at least the filling mass in the part of the capsule after the filling operation is recorded using digital imaging in a first step, the contour of the filling mass in the part of the capsule is determined from the digital imaging recording in a second step, and the contour is analysed in a third step in order to assess the filling operation in comparison with the predefined contour. The invention provides for external influences on the image properties to be compensated for by controlling the optical system.
Abstract:
Pulsed hyperspectral, fluorescence, and laser mapping imaging in a light deficient environment is disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system includes a controller configured to synchronize timing of the emitter and the image sensor. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of a hyperspectral emission, a fluorescence emission, or a laser mapping pattern.
