Abstract: A phase difference observation apparatus includes a light source; an illumination guide to guide illumination light from the light source to an observation target object in a cell culture vessel; an optical imager to form an optical image of the observation target object on an image sensor; and a controller. The illumination guide includes a spatial modulator to change an intensity distribution of the illumination light; the controller contains intensity distribution correction information associating a position of the imaging guide with respect to the cell culture vessel with an intensity distribution of illumination light at the position of the optical imager; the controller acquires imaging system position information, which is the position of the optical imager; and the controller changes an intensity distribution of illumination light in the spatial modulator on the basis of the imaging system position information and the intensity distribution correction information.

The controller includes at least one processor that is configured to detect, using image data that includes the cell captured by an observation unit and a learned model capable of detecting a target cell or a non-target cell, a target cell or a non-target cell in the image data; set a region where the target cell is present or a region where the non-target cell is not present as a laser irradiation region to be subjected to laser irradiation by the laser emitter, and apply a laser emitted from the laser emitter to the laser irradiation region in the cell culture tool to treat the target cell.

Abstract: The processing apparatus 200 of the present disclosure includes: a laser irradiation unit 21 capable of applying a laser to the photothermal conversion layer 13 of the cell culture tool 100 including the cell culture base layer 11 and the photothermal conversion layer 13; and a control unit 22 for controlling the laser irradiation unit 21. The control unit 22 includes a setting section 221 and an irradiation control section 222. The setting section 221 sets an irradiation region to be irradiated with the laser in the cell culture tool 100. The irradiation control section 222 controls the laser irradiation unit 21 based on the irradiation region such that the laser irradiation unit 21 applies the laser to a corresponding region of the photothermal conversion layer 13.

Abstract: The present invention provides a phase difference observation apparatus that can reduce the size of the apparatus by not requiring an additional imaging unit and can suppress deterioration of the phase difference image due to the meniscus. The phase difference observation apparatus of the present invention includes a light source; an illumination optical system that guides illumination light from the light source to an observation target object in a cell culture vessel; an imaging optical system that forms an optical image of the observation target object on an image sensor; and a control unit.

Abstract: Provided is a liquid crystal display device that can suppress, more than the prior art, lowering of display quality when low-frequency drive is being carried out. The liquid crystal display device is operated in a low frequency drive mode. A source driver applies a gradation voltage during write periods and an idle period voltage during an idle period to each source line. The value of the idle period voltage is, for example, an average value of a maximum gradation positive voltage, a maximum gradation negative voltage, a minimum gradation positive voltage, and a minimum gradation negative voltage. By making the voltage for each source line during the idle period be the idle period voltage, potential variations in the source lines when switching from the write periods to the idle period are smaller than the prior art.

Abstract: A display device includes an image processing unit including a detection unit to detect a flicker pattern having a checkered pattern arrangement included in an input image that has been input; and a conversion unit to, if the detection unit detects the flicker pattern included in the input image, convert the input image into an output image that does not include the flicker pattern.

Abstract: An object of the present invention is to provide an image processing apparatus which allows a user to execute image processing, such as extraction and elimination of a portion common to a plurality of images therefrom, with a simple operation. An image of a document is read by a scanner, and when the document is a first one, the image of the document is stored from input means into storing means. When an image of a second document is read, comparing means compares the read image with the image stored in the storing means to judge whether or not a difference in pixel values between the first document image and the second document image is smaller than a threshold value set through setting means.
