Cell image processor and cell image processing method
View Patent ↗Cells showing specific characters can be separated from noise, extracted, and analyzed, through processing of a cell image. It is intended to provide a cell image processor ( 1 ) comprising: a characteristic quantity measuring section ( 11 ) which processes a cell image obtained by photographing cells to measure characteristic quantities of respective cells in the cell image; a characteristic quantity distribution forming section ( 12 ) which forms the distribution of the thus measured characteristic quantities; a group forming section ( 13 ) which divides cells having continuously distributed characteristic quantities into groups in the thus formed characteristic quantity distribution; and a specific cell extracting section ( 14 ) which extracts cells having characteristic quantities falling within a predetermined range at both ends of a characteristic quantity distribution in each group, as specific cells.
1. A cell image processor comprising:
a characteristic quantity measuring section which processes a cell image obtained by photographing cells to measure characteristic quantities of respective cells in the cell image;
a characteristic quantity distribution forming section which forms the distribution of the thus measured characteristic quantities;
a group forming detecting section that detects the characteristic quantity at one or more peaks from the distribution of the characteristic quantity formed by the characteristic quantity distribution forming section; and
a specific cell extracting section which extracts cells having continuously distributed characteristic quantities being centered at one or more peaks in the thus formed characteristic quantity distribution, as specific cells.
2. A cell image processor according to claim 1 , wherein said specific cell extracting section excludes cells having discontinuously distributed characteristic quantities.
3. A cell image processor according to claim 1 , wherein
said characteristic quantity measuring section measures a plurality of types of characteristic quantities of respective cells, and
said characteristic quantity distribution forming section forms a characteristic quantity distribution in correlation with the plurality of types of characteristic quantities.
4. A cell image processor according to claim 1 , wherein a setting of an extracted range of said specific cell extracting section is changeable.
5. A cell image processor according to claim 1 , comprising a display unit which divides cells having continuously distributed characteristic quantities into groups in the characteristic quantity distribution that has been formed by said characteristic quantity distribution forming section, and displays them respectively by groups.
6. A cell image processing method comprising:
a measuring step for processing a cell image obtained by photographing cells to measure characteristic quantities of respective cells in the cell image;
a distribution forming step for forming the distribution of the thus measured characteristic quantities;
a group forming step for detecting the characteristic quantity at one or more peaks from the distribution of the characteristic quantity formed by the characteristic quantity distribution forming section; and
an extracting step for extracting cells having continuously distributed characteristic quantities being centered at one or more peaks in the thus formed characteristic quantity distribution, as specific cells.
7. A cell image processing method according to claim 6 , wherein said extracting step is to exclude cells having discontinuously distributed characteristic quantities.
