  • Patent number: 8531762
    Abstract: A confocal microscope apparatus comprises a first optical scanning system which obtains a scan image of a sample using a laser beam from a first laser light source, a second optical scanning system which scans specific regions of a sample with a laser beam from a second laser light source that is different from the first laser light source, thereby causing a particular phenomenon, and a beam diameter varying mechanism which can change the beam diameter of the laser beam of at least one of the first optical scanning system and the second optical scanning system. With this configuration, the apparatus further comprises an excitation light intensity distribution calculator which calculates and stores the excitation light intensity distribution along a depth direction on the sample surface from the beam diameter of the laser beam output from the beam diameter varying mechanism.

  • Patent number: 8290263
    Abstract: An image processing apparatus includes a photographing condition estimation unit for estimating a photographing condition of the input image based on photometric information and focal information. A Y/C separation unit separates the input image into a luminance signal and a color difference signal; a luminance correction unit extracts an edge from the luminance signal and corrects the luminance signal by a gradation conversion curve; a color difference correction unit corrects the color difference signal based on luminance signals obtained before and after the gradation correction and a theoretical limit characteristic of color reproduction; a skin color correction unit performs skin color correction depending on the photographing condition; and a Y/C synthesis unit synthesizes the luminance signal and the color difference signal obtained after the correction. Gradation correction is performed on the input image such that appropriate hue and saturation are achieved while emphasizing a main object.

A display section displays the subject image based on image data associated with the subject image obtained by the imaging section. A mode selecting section selects either a first mode in which the electronic still camera performs imaging operation using the imaging section while a user views the subject image through the finder optical system or a second mode in which the electronic still camera performs imaging operation using the imaging section while the user views the subject image on the display section. A first focus detection circuit performs a first focus detecting operation when the first mode is selected by the mode selecting section. A second focus detection circuit performs a second focus detecting operation when the second mode is selected by the mode selecting section.

    Abstract: An ultrasonic operating apparatus of the present invention includes an apparatus main body having a vibration driving circuit for generating a driving signal to apply ultrasonic vibrations to a vibration generating portion of a hand piece and having a control portion for generating the driving signal and for systematically controlling the apparatus. An operating and display panel and a water supply pump are arranged to an outer surface of the apparatus main body, and the driving signal is supplied to the hand piece via a connector. Until a user carries out a correct processing routine, the control portion does not perform the above control operation even though the user may execute another control operation. Further, the control portion controls an operation so that an incorrect processing routine is notified to the user on the operating and display panel.
