20090092319 | PHASE-INFORMATION EXTRACTION METHOD - Only phase information of a measurement object is extracted with superior precision from a phase-information image in which background phase information is superimposed on phase information of the measurement object. A method of extracting phase information of a measurement object includes a region-specifying step of specifying a region in which a measurement object exists and a region in which no measurement object exists in a phase-information image containing measurement objects, showing a two-dimensional distribution of phase information to be measured, a background-image creating step of creating a background phase-information image by interpolating the phase information of the region in which the measurement object exists on the basis of the phase information of the region in which no measurement object exists, specified in the region-specifying step; and a difference calculating step of calculating a difference between the background phase-information image created in the background-image creating step and the phase-information image. | 04-09-2009 |

20090097734 | CELLULAR THICKNESS MEASUREMENT METHOD - To enable precise measurement of a cellular thickness distribution regardless of changes in the refractive index of cell(s). Two-dimensional distribution of phase information is obtained, in a state where a first culture solution having a first refractive index is stored so as to completely immerse cells adhered onto a bottom face of a culture vessel, by transmitting light of a wavelength, and by photographing the transmitted light. Next, two-dimensional distribution of phase information is obtained, in a state where a second culture solution having a second refractive index is stored to have a depth to completely immerse the cells in the culture vessel, by transmitting light, and by photographing the transmitted light. Next, respective average values of the phase information are calculated. Next, the refractive index of the cell is estimated. Next, the thickness dimension is calculated using the refractive index. | 04-16-2009 |

20140211600 | RECORDING/REPRODUCING DEVICE AND OPTICAL DISK LIBRARY DEVICE - In a recording/reproducing device for recording and reproducing an optical disk, when performing verify processing of inspecting a quality of recorded data and compare processing of inspecting whether the recorded data can be read without errors, a time is taken because the same area needs to be reproduced two times. The verify processing and the compare processing are performed at one time reproduction. To perform the verify processing and the compare processing simultaneously, a recording quality storage part is provided in the recording/reproducing device, and reproduced data is transmitted to a host controller while storing quality information at the time of reproduction by an instruction of the host controller. The host controller performs the compare processing by comparing transmitted data and data at the time of recording and inspects the recording quality by acquiring the quality information of a reproduced area from the recording/reproducing device at intervals set in advance. | 07-31-2014 |
