In an image acquisition device, when capturing an optical image of a sample S through lane scanning, the number of tile images T included in a tile image row R acquired in one lane is counted, and a determination is made as to whether or not the number of images reaches a planned acquisition count that is set in advance. In a case where it is determined that the number of images does not reach the planned acquisition count, lane scanning with respect to the lane is re-executed. Accordingly, even when a loss of the tile images T occurs due to an environment load, the tile images T are complemented by re-execution of the lane scanning, and thus it is possible to prevent the loss of the tile images T in an observation image.

Image acquisition device and image acquisition method

An image acquisition device includes a cassette mounting unit in which a cassette is detachably mounted, the cassette holding the slide glasses in a plurality of stages in a predetermined arrangement direction, a light source that emits inspection light toward the cassette, a scanning unit that performs scanning with the inspection light in the arrangement direction, a light reflection unit that is disposed on the back surface side of the cassette and reflects the inspection light emitted from the light source, a light detection unit that detects reflected light including the inspection light reflected by at least one of the light reflection unit, the cassette, and the slide glass, and outputs a detection signal, and an information generation unit that generates holding information on a holding position and/or a holding state of the slide glass held in the cassette on the basis of the detection signal.

An image pickup deviceA is constructed with a photodetecting sectionhaving a plurality of pixels; a charge transfer sectionhavingsegmental charge transfer sections Tto T; an A/D converting sectionthat converts signals from the charge transfer sectionto digital data signals; and a digital signal processing section. The digital signal processing sectioncarries out, to a correction target of a data signal outputted first in a signal array from the segmental charge transfer section, a data correction by use of a plurality of correcting data signals including at least one of a first correcting data signal included in the signal array and a second correcting data signal included in another signal array from a segmental charge transfer section adjacent to an output end side of the segmental charge transfer section. Thereby, realized are an image pickup device that is capable of favorably reducing influence of an abnormal output produced in data signals and a microscope apparatus using the same.

Imaging apparatus and microscope apparatus using the same

An imaging apparatusA includes an electron multiplying solid-state image pickup device which has an electron multiplier section for multiplying charge signals generated in respective pixels; a multiplication gain setting partfor setting a multiplication gain in the electron multiplier section; a standard deviation calculatorfor calculating a noise standard deviation of a noise image acquired under a predetermined condition by the image pickup device; a reference standard deviation storagestoring a reference standard deviation, and a standard deviation comparatorfor comparing the noise standard deviation and the reference standard deviation and outputting an obtained comparison result. At the time of gain adjustment, the multiplication gain setting partadjusts the multiplication gain based on the comparison result by the standard deviation comparator. Thereby, an imaging apparatus which enables the user's side to easily and accurately re-adjust the multiplication gain of charge signals in the electron multiplying solid-state image pickup device, and a gain adjusting method for the same are realized.

Imaging apparatus and gain adjusting method for the same

An imaging apparatus includes an image pickup device having a two-dimensionally arrayed pixel structure, an A/D converter which converts analog signals from the respective pixels into digital data signals, and a DSPwhich performs signal processing for the data signals. The DSPincludes an image data storagewhich stores the data signals in units of data signal sequences corresponding to pixel lines, a mask processorwhich sets an integer n not less than 2 as a dilation coefficient and performs mask processing to dilate image components in the image data to n&#xd7;n, and a data storing controllerwhich sets n calculation memory regions in which n data signal sequences corresponding to n pixel lines are stored, in the storage, according to the dilation coefficient n. Thereby, an imaging apparatus capable of acquiring an image with excellent visibility even under conditions of a low illuminance, etc., is realized.
