An image processing device (A) comprises: an input means for inputting a brightfield image representing cell morphology in a tissue section, and a fluorescence image representing, by fluorescent bright spots, the expression of a specific protein in the same range of the tissue section; a first generation means for generating a cell image obtained by extracting a specific site of a cell from the brightfield image; a second generation means for generating an image obtained by extracting bright spot regions from the fluorescence image, creating a brightness profile for each bright spot region, and generating a fluorescent particle image obtained by extracting the fluorescent particles in the bright spot regions on the basis of the fluorescence profile for one fluorescent particle, which serves as a fluorescence bright spot source; and a calculation means for superimposing the cell image and the fluorescent particle image on one another.

Image processing device, pathological diagnosis support system, storage medium for image processing, and image processing method

An image processing apparatus contains an input unit to input a fluorescent image and a morphological image of a tissue. A biological substance expressed at a first structure of a cell in the tissue is stained by a fluorescent substance. The fluorescent image illustrates a fluorescent bright point which represents expression of the biological substance. The morphological image illustrates a morphology of a second structure of a cell in the tissue and contains the same range of the tissue as the fluorescent image. The apparatus further contains a feature amount extraction unit to extract a feature amount of the second structure from the morphological image, a bright point extraction unit to extract the fluorescent bright point from the fluorescent image, and a region of interest determination unit to determine a region of interest based on the feature amount of the second structure and a distribution of the fluorescent bright point.

Image processing apparatus and computer readable medium for image processing

An image processing device prepares an interest image from an image obtained by photographing a cell in a sample and includes a cell image inputting unit, a setting unit, a preparation unit, and a display. The image is input to the image inputting unit. The setting unit sets one or more target images in the image. The preparation unit prepares plural candidate images by performing image processing of each of the one or more target images using one or more prescribed parameters. The display displays the plural candidate images prepared by the preparation unit.

An image processing device inputs a bright field linage of a tissue slice in which a cell nucleus is stained and a fluorescent image of the tissue slice in which a specific biological substance is stained with a fluorescent staining reagent (S), extracts a cell nucleus from the image of the cell nucleus (S), extracts a fluorescent bright point from the fluorescent image (S), specifies a cell nucleus to which the fluorescent bright point is assigned on the basis of the distance between the cell nucleus and the fluorescent bright point, and assigns the fluorescent bright point with the cell nucleus (S).

Image processing device and storage medium for image processing

An image input device capable of obtaining a luminance signal and a chromaticity signal appropriately even when photographing at nighttime is provided. Further, an image processing device capable of forming an image in which an object can be confirmed visually even under a low luminance environment is provided. Since a color space converting unit assigns weights to the visible light component and the infrared light component based on positional information acquired by the positional information acquiring unit, and converts the original image data into color space including the luminance signal and the chromaticity signal, it is possible to obtain the color space appropriately according to a height of the object and a distance to the object.
