Abstract:
1. An observation device comprising: a stage on which a fluid vessel containing therein an object to be observed, the object including a cell or microorganism which is to be placed in the fluid vessel; an observing part observing the object to be observed; a driving part performing a stage driving for moving a position of the stage with respect to the observing part; and a control part controlling the stage driving performed by the driving part, the stage driving including a moving mode for moving the stage toward a predetermined position and a stop process mode for performing a compensation control after the moving mode to thereby stop the stage at the predetermined position, wherein the control part performs a compensation control as the stop process in the stop process mode, in the compensation control the control part configured: to determine whether or not a driving of the driving part is stopped, to perform a first driving and a second driving after the first driving if the driving of the driving part is stopped, not to perform the first driving and the second driving if the driving of the driving part is not stopped, and then to stop the stage driving, the first driving being for changing the position of the stage with respect to the observing part in a predetermined direction in accordance with a first driving parameter which is a parameter regarding a velocity or an acceleration of the stage driving, the second driving being for changing the position of the stage with respect to the observing part in a direction opposite to the predetermined direction in accordance with a second driving parameter which is a parameter regarding the velocity or the acceleration of the stage driving.
