A recording medium having an observation program recorded therein, the program may cause a computer to execute: an entire-image-pickup process of picking up an image of a sample by picking up an image of an entire container containing the sample and a solution; a sample-mass-identification process of identifying a sample mass having the samples gathering therein, from the image picked up in the entire image-pickup process; a sample-mass-determination process of extracting shape information of the identified sample mass, and determining a state of the sample mass based on the shape information; a coordinate-detection process of selecting a magnifying-observation-target sample mass from the identified sample masses, and detecting coordinates of the center of the magnifying-observation-target sample mass.
