For example, a ligand or a receptor is fixed at different positions on a glass slide or membrane filter carrier surface, and a receptor or ligand labeled with an antigen (hereinafter referred to as a labeled receptor or labeled ligand) is hybridized to the carrier surface. Specific binding to the ligand or receptor immobilized thereon, followed by labeling the antibody against a substance such as an antigen labeling the labeled receptor or labeled ligand with a labeling substance that produces chemiluminescence, such as an enzyme. (Hereinafter referred to as an enzyme-labeled antibody), this enzyme-labeled antibody is specifically bound to a labeled receptor or an antigen of a labeled ligand, and is further contacted with a chemiluminescent substrate that specifically binds to the enzyme of the enzyme-labeled antibody. The chemiluminescence in the visible light wavelength region caused by the contact between the substrate and the enzyme Obtained as an image signal by photoelectric conversion, a system for analyzing a substance derived from a living organism such as an antigen by the display monitor a visible image based on the image signal has been proposed by the like.
[0004]
Here, in the system as described above, the chemiluminescence detected by the CCD is very weak. Therefore, in order to appropriately analyze a substance derived from a living body, the signal photoelectrically converted by the CCD is used. It is necessary to display on the monitor a visible image that can be subjected to appropriate gradation processing and can be appropriately analyzed. In order to perform appropriate gradation processing as described above, it is necessary to assign an appropriate density range to an image signal in an intensity range corresponding to the intensity of chemiluminescence among image signals obtained by a CCD. Therefore, conventionally, for example, in order to visually recognize an image signal in an intensity range corresponding to the intensity of chemiluminescence, a histogram indicating the intensity distribution of the image signal has been displayed. Further, in order to visually recognize the density range in gradation processing, a gradation image indicating the density range is displayed. Patent Document 1 proposes a method of displaying a histogram for all image signals and designating an image signal range in an intensity range corresponding to the intensity of chemiluminescence in the histogram.

Further, when the operator wants to change the intensity range of the image signal to be subjected to gradation processing and the density range of gradation processing to an appropriate range by viewing the display as described above, for example, in advance in a gradation processing program or the like. It was necessary to change the set numerical value directly, and the work was complicated. In addition, when the numerical value is directly changed as described above, it is recognized which side the specific value is distributed in the histogram or which side corresponds to the color in the gradation image. It was difficult.
[0007]
In view of the above circumstances, an image processing condition display method and apparatus according to the present invention performs gradation processing on an image signal as described above, and displays a visible image based on the image signal subjected to the gradation processing. In addition, in the image processing condition display method and apparatus for displaying the processing conditions of the gradation processing, the mutual relationship between the intensity range of the image signal subjected to the gradation processing and the density range of the gradation processing is visually recognized. An object of the present invention is to provide an image processing condition display method and apparatus capable of easily specifying an appropriate range and displaying an appropriate visible image for analysis of a substance derived from a living body as described above.
