Imaging device for microscope

An imaging device for a microscope that images a sample placed on a stage, applies signal processing to the sample, and displays the sample on a monitor, comprising:

• an imaging unit that images the sample to obtain a video signal;
• a signal processing unit that applies signal processing to the video signal obtained by the imaging unit;
• a movement detection unit that calculates a relative moving speed between the imaging unit and the stage in a first direction perpendicular to an optical axis of the imaging unit;
• a signal processing setting unit that determines a parameter such that, in the case where the relative moving speed in the first direction is more than or equal to a predetermined threshold value, time required for the signal processing performed by the signal processing unit is reduced as compared with the case where the relative moving speed is less than the predetermined threshold value;
• and,
• a frame rate conversion unit that selects between a process of, in the case where the relative moving speed in the first direction is more than or equal to the threshold value, increasing a frame rate of the video signal subjected to the signal processing by the signal processing unit as compared with the case where the relative moving speed is less than the threshold value, and a process of maintaining a current frame rate, thereby to apply the selected process, wherein
• the signal processing unit applies the signal processing in accordance with the parameter determined by the signal processing setting unit.
