Provided is a charged particle beam apparatus capable of more objectively and highly accurately calculating a feature of a cell from an observation image of a cell and evaluating a cell. The charged particle beam apparatus includes an image acquisition unitthat acquires an image of a cell, a contour extraction unitthat extracts a contour of the image, a feature calculation unitthat calculates a morphological feature of the contour based on the contour and calculates the feature of an internal structure such as a cytoplasm contained in an internal area of the contour, and a determination unitthat determines quality and/or functionality of the cell based on the feature, and can objectively and highly accurately evaluate the quality and/or the functionality of the cell included in the captured image.

Charged particle beam apparatus and cell evaluation method

Provided is an image classification device that facilitates efficient creation of teacher data and comprehensive evaluation on a basis of knowledge and experience of the user. The image classification device includes: an image input unit that acquires an image; an image display unit that displays the image acquired by the image input unit; an image analysis unit that calculates a feature amount from the acquired image; a feature amount display unit that displays the calculated feature amount; an extraction and sorting condition input unit that specifies an extraction and sorting condition with regard to the feature amount; an extraction and sorting processing unit that performs extraction and sorting processing based on the condition; an extraction and sorting processing result display unit that displays a result; an user classification input unit that allows a user to input a classification destination with regard to the image; and a user classification result display unit that displays an classification input content.

Imaging device and morphological feature data display method

The invention provides a method of preparing a biological tissue sample and a method of observing a biological tissue section sample that enable stereoscopic observation of a biological tissue easily and rapidly without destroying a biological tissue piece. The method of observing a biological tissue sample according to the invention is a method in which stereoscopic morphology of a biological tissue sample is observed, and the method includes: cutting out a sample having a thickness of 15 to 50 &#x3bc;m from a sample block obtained by fixing, dehydrating, and paraffin-embedding a sample cut out from a biological tissue; transferring the sample to a surface-treated slide glass; stretching the sample on the slide glass; performing deparaffinization processing; then, staining the sample with a heavy metal-based staining agent; and observing the stained sample with a scanning electron microscope.
