  • Patent number: 11071460
    Abstract: In a photoacoustic measurement apparatus and a photoacoustic measurement system, it is possible to generate blood flow information using a photoacoustic image without requiring a separate tourniquet. A light source emits measurement light. A probe detects a photoacoustic wave generated in a subject after measurement light is emitted to the subject in each of the avascularized condition in which the subject is avascularized and the non-avascularized condition in which the subject is not avascularized. Photoacoustic image generation unit generates a photoacoustic image based on the detection signal of the photoacoustic wave. Blood flow information generation unit generates blood flow information based on the signal value of a photoacoustic image in a region of interest set in the photoacoustic image. The avascularization of the subject is performed by pressing the probe against the subject.

  • Patent number: 10653295
    Abstract: An image processing apparatus includes: an image acquisition unit that acquires a plurality of endoscope images obtained by imaging an observation target at different times with an endoscope; a blood vessel extraction unit that extracts blood vessels from the plurality of endoscope images; a blood vessel index value calculation unit that calculates a blood vessel index value for each of the blood vessels extracted from the endoscope images; a temporal change calculation unit that calculates a temporal change of the blood vessel index value; a determination unit that determines a state of a mucous membrane of the observation target using the temporal change of the blood vessel index value; and a monitor that displays a determination result of the determination unit.

  • Patent number: 10402960
    Abstract: A drug collation device 10 includes a registered image acquisition unit 12 that acquires an image of a drug as a registered image on the basis of prescription information 22, a collation image acquisition unit 14 that acquires an image of a drug to be collated as a collation image, a similarity calculation unit 16 that calculates similarities between partial images in each corresponding divided region among a plurality of divided regions of the registered image acquired by the registered image acquisition unit 12 and a plurality of divided regions of the collation image acquired by the collation image acquisition unit 14, and a determination unit 18 that determines whether the drug indicated by the registered image and the drug indicated by the collation image are the same type, on the basis of the lowest similarity among a plurality of similarities calculated by the similarity calculation unit 16.

  • Publication number: 20130283157
    Abstract: A digital comic viewer device comprising: a determination unit that determines whether or not an entire translated text corresponding to a speech balloon region in the image displayed on the screen of the display unit is fitted within the speech balloon region in a preset letter size; and a translated text display control unit that displays the translated text instead of a dialogue of an original text within the speech balloon region based on the acquired speech balloon information and text information, the translated text display control unit displaying the entire translated text in the speech balloon region when the entire translated text is fitted, and rewriting a speech balloon corresponding to the speech balloon region to a horizontally-long speech balloon and displaying the translated text in a speech balloon region of the horizontally-long speech balloon when the entire translated text is not fitted.
