摘要
An ophthalmic apparatus (1) includes: a screen (11); a examination controller (3); a first image projection unit (5) projecting a target image; a second image projection unit (7) projecting a pointer image; a mirror (9) reflecting the projections of the first and second image projection units (5) and (7) to project the same onto the screen (11); and a pointer operation input unit (13) through which the pointer position is inputted. The examination controller (3) includes: a first image generation unit (21) generating a target image; an image correction unit (22) correcting the target image so that the target image does not look distorted on the screen (11); a calculation storage unit (24) calculating the position of the pointer according to the input through the pointer operation input unit (13) and storing the calculated position; a second image generation unit (23) generating the image of the pointer; and an output unit (25) presenting or outputting the target image and the position of the pointer.
