A biological sample image acquiring apparatus includes: a sample stage on which a biological sample is placed and which can move in a direction; an objective lens magnifying a region of the biological sample; an imaging device imaging the region magnified by the objective lens; a stage on which the imaging device or the objective lens is placed and which can move in a corresponding direction of the direction; a first moving mechanism moving the sample stage so that a target region of the biological sample is located at an imaging range; a second moving mechanism moving the stage in the corresponding direction at a movement speed obtained by multiplying a movement speed of the sample stage by a magnification of the objective lens; and an imaging controller starting the exposure of the imaging device before the sample stage moved by the first moving means is stopped.
