An information processing device that reconstructs an original image including an interference fringe image of an object to be observed includes at least one processor. The processor acquires the original image, generates a reconstructed image while changing a reconstruction position from an initial position based on the original image, calculates sharpness of the reconstructed image each time the reconstructed image is generated and detects an in-focus position where the calculated sharpness is maximized, records the in-focus position, decides the initial position in a next reconstruction processing based on the in-focus position, and repeats the original image acquisition every one imaging cycle.

Information processing device, and operation method and operation program thereof

An imaging apparatus includes: an illumination device that has a plurality of light sources which irradiate an observation target with illumination light beams at different irradiation angles; an imaging sensor that captures an interference fringe image generated by the observation target irradiated with the illumination light beams to generate image data; a height adjustment mechanism that enables a height of the illumination device with respect to the imaging sensor to be adjusted; and an angle change mechanism that changes the irradiation angle of the illumination light beam in accordance with the height such that an intersection of central axes of the illumination light beams emitted from the plurality of light sources is located on the observation target.

Imaging apparatus and information processing apparatus

An endoscope system comprises an image acquisition unit, a discrimination processing unit, and a discrimination processing control unit. The image acquisition unit acquires an endoscope image obtained by imaging an observation target using an endoscope. The discrimination processing unit discriminates a portion having a specific feature in the observation target by performing discrimination processing, using an endoscope image. The discrimination processing control unit controls a start or an end of the discrimination processing on the basis of a change in operation of an endoscope or the endoscope image.

A control device includes a processor. The processor acquires positional information indicating a position of an observation target. The processor sets, from among a plurality of irradiation positions, a required irradiation position, which is an irradiation position corresponding to the position of the observation target indicated by the positional information and is an irradiation position required for obtaining a plurality of the interference fringe images that are sources of a super-resolution interference fringe image having a resolution exceeding a resolution of an imaging element. The processor causes a light source to emit an illumination light from the required irradiation position by controlling an operation of the light source, and causes the imaging element to outputs the interference fringe image at each required irradiation position.

There are provided an acoustic wave image generating apparatus for generating a B-mode image having a fixed brightness and a control method thereof. First brightness information () indicating the brightness of a first B-mode image in the depth direction of the subject is generated. Positional deviation correction is performed on an acoustic wave echo signal having a positional deviation between the focusing position of acoustic waves and the observation target position, and second brightness information () indicating the brightness in the depth direction of the subject is generated from a superposition signal obtained by superimposing an acoustic wave echo signal for which the positional deviation has been corrected and an acoustic wave echo signal without positional deviation. The brightness of the first B-mode image is corrected based on the first brightness information and the second brightness information.
