  • Patent number: 11321836
    Abstract: An image-processing device including: a determination unit that determines a captured image on the basis of a ratio of cells and a distribution of the cells in the captured image acquired by imaging a sample including cells; and an area setting unit that sets an area used for analyzing the cells of the sample on the basis of a result of the determination acquired by the determination unit.
    Type: Grant

  • Patent number: 8131068
    Abstract: An image matching device includes: a dividing unit that divides a target image, contained in a search window set within an input image constituted with pixels each having a luminance component and a chrominance component, and a template image constituted with pixels each having the luminance component and the chrominance component, each into a plurality of divided areas; a representative value calculation unit that calculates a luminance component representative value and a chrominance component representative value in correspondence to each of the divided areas; a normalizing unit that normalizes the luminance component representative value having been calculated in correspondence to each divided area; and a template matching processing unit that executes template matching processing based upon the normalized luminance component representative value and the chrominance component representative value corresponding to each of the divided areas in the template image, and upon the normalized luminance component

  • Patent number: 4167018
    Abstract: A MIS capacitance element formed in a semiconductor substrate of p-(or n-) conductivity type comprises an n- (or p-) type well region formed in one principal surface of the semiconductor substrate and a polycrystalline region formed on the surface of the well region through a gate insulator layer. A polar voltage is applied between the well region and the polycrystalline layer so that the well region is forward biased and no carrier channel region is formed in the surface of the well region. The MIS element is particularly suited for use in a complementary MIS IC and provides almost no voltage or field dependency of the capacitance.

  • Patent number: 4011467
    Abstract: In a gate input circuit for insulated gate field effect transistors, an insulated gate field effect transistor of depletion type is used, whose drain electrode (or source electrode) is connected to one terminal of a power source and whose source electrode (or drain electrode) is short-circuited with the gate electrode and connected to an input terminal of the gate input circuit through a resistor.
