Claim:
1. A magnifying observation apparatus comprising: a placement stage having a placement surface for placing an observation object; a light source configured to irradiate the observation object with illumination light; an imaging unit including a camera and a lens, having an optical axis, and configured to sequentially acquire an observation image of the observation object; a z-axis stage lift configured to change a relative distance between the placement stage and the imaging unit along a first direction orthogonal to the placement surface or in parallel with the optical axis; an xy-axis movable coupling configured to change a relative lateral position of the placement stage and the imaging unit along a second direction in parallel with the placement surface; a display configured to display an image with respect to the observation image; and a controller operably coupled to the imaging unit and the display, configured to: synthesize the observation image sequentially acquired to generate an enhanced observation image, in a first display mode, control the display to display the enhanced observation image, in a second display mode, control the display to display, at a higher update rate than the first display mode, the observation image sequentially acquired by the imaging unit or a simple processed observation image generated by processing the observation images simpler than synthesizing the observation images to generate the enhanced observation image, detect a change with respect to the observation image acquired by the imaging unit, determine an end of the change with respect to the observation image acquired by the imaging unit, switch from the first display mode to the second display mode in response to the change detected by the controller in the first display mode, and switch from the second display mode to the first display mode in response to the end of the change determined by the controller in the second display mode.
