Abstract: A proposition is to accurately evaluate a phototoxic property (cell function) concerning a living cell. To this end, an evaluating method of cell function includes the operations of dyeing a specific site of the living cell with a fluorescent dye, irradiating the living cell with light to measure changes in brightness of resulting fluorescence generated at an adjacent site of the specific site, and evaluating the phototoxic property based on the brightness changes. In the event of functional depression in the specific site, the fluorescent dye cannot be retained therein and is extravasated into the adjacent site through the membrane of the specific site. The present embodiment can measure the extent of this extravasation, making it possible to accurately evaluate the phototoxic property.

Abstract: The invention relates to a file management apparatus for performing file management using file names, and is intended to provide a file management apparatus that allows handling of files by simple operations. The file management apparatus has a structure information setting section, a data acquiring section, a name-generating section, and a managing section. The structure information setting section arbitrarily sets structure information that defines structure of file names. The data acquiring section acquires data to be stored as a file. The name-generating section acquires, for each data acquired by the data acquiring section, information structuring a file name according to the structure information set by the structure information setting section, and generates a file name using the acquired information. The managing section stores the data acquired by the data acquiring section, and manages the data using the file names generated by the name-generating section.

Abstract: This invention provides an image processing apparatus capable of obtaining a satisfactory operation environment and a computer-readable medium recording thereon a program for allowing a computer to function in the same way as the image processing apparatus, based on the still image data and the live image data acquired. The image processing apparatus acquires still image data and live image data of an object, and simultaneously displays a still image and a live image of the object on a display screen of a display device provided inside or outside the apparatus. The image processing apparatus lays a first display space and a second display space having different sizes out on the display screen so that they don't overlap each other, and assigns the still image data and the live image data acquired to the first and second display spaces, respectively.

Abstract: An ophthalmic refractor is constructed to judge whether a visual acuity value of a symbol with a mask is minimum or maximum among values in a selected charts, select a chart containing a symbol indicating a visual acuity value smaller than the minimum visual acuity value when the visual acuity value is judged to be minimum, and select a chart containing a symbol indicating a visual acuity value larger than the maximum visual acuity value when the visual acuity value is judged to be maximum.

Abstract: An ophthalmologic device measures corneal curvature and ocular refractive power of the eye by imaging the positions of a plurality of bright points which result from plural light rays and by imaging a predetermined pattern of the eye. The ophthalmologic device includes a frame memory to store picture data of the eye which has been imaged by a video camera. The picture data in memory is classified into bright spot regions in which bright spots are present one at a time, a corneal reflected image region in which a reflected image from the cornea of a predetermined pattern is projected into the fundus of the eye, and mask regions in which the bright points and the corneal reflected image are not present. The picture data having a luminosity greater than a predetermined threshold value is stored for later calculation of a centroid of the bright points to measure the corneal curvature of the eye.

Abstract: An eye examination apparatus comprises an ultrasonic transmitter for transmitting ultrasonic wave radiation to an area around an eye to be examined, an ultrasonic receiver for receiving the reflected wave radiation of the ultrasonic wave radiation, and a judging device for judging whether the eye to be examined is the right eye or the left eye based on the result of the reception by the ultrasonic receiver.

Abstract: An ophthalmologic apparatus comprises a measuring device for measuring an eye being examined, a display for displaying the result of the measurement by the measuring device, a counter for counting the number of times of measurement of the eye being examined with respect to each of the right and left eyes, and a display control device for causing the display to display the number of times of measurement of each of the right and left eyes counted by the counter.

Abstract: An eye measuring apparatus includes a refracting power detector for measuring the refracting power of an eye to be examined, a fogging producer for moving the position of a target image in the direction of the optical axis of the eye to be examined, and a feedback controller for receiving an output from the refracting power detector, and moving the position of the target image in a direction, in which accommodation of the eye to be examined is relaxed, in accordance with refracting power information measured in a predetermined meridian direction of the eye to be examined and astigmatic information of the eye to be examined obtained from refracting power values measured in a plurality of meridian directions of the eye to be examined.

Abstract: The apparatus radiates light onto an eye to be examined and picks up an image of the eye, which is irradiated with light. And then the apparatus compares image information obtained from the image pickup with a threshold determined in advance for the image information so as to store the image information larger than the threshold. The apparatus calculates a measured value of the eye to be examined on the basis of the stored image information.

Abstract: In an optical system a semitransparent mirror which is disposed at a predetermined angle with respect to an optical axis and which has a semitransparent surface (for instance, a front surface) and a transparent surface (for instance, a rear surface) is so designed as to split a diverging or converging light incident thereon into a first optical path of light flux reflected from the semitransparent surface and a second light path of light flux transmitted through both the semitransparent and transparent surfaces. Furthermore, in order that the position of an image focused by the light flux reflected from the transparent surface coincides with the position of an image focused by the light flux reflected from the semitransparent surface, the transparent surface is made non-parallel with the semitransparent surface of the semitransparent mirror. The thickness of the mirror decreases or increases toward image planes depending upon whether converging light flux or diverging light flux is incident on the mirror.
