Abstract:
1. An ophthalmic apparatus comprising: a first measurement unit placed in a main body of the apparatus, which measures a first eye characteristic of an examinee's eye, the unit comprising a second measurement unit placed in the main body of the apparatus in a position in an up-and-down direction with respect to the first measurement unit, which measures a second eye characteristic of the eye, the unit comprising an up-and-down movement mechanism which moves the body of the apparatus in the up-and-down direction with respect to the eye; a display device capable of displaying the anterior-segment image based on an image-pickup signal outputted from the first image-pickup element and the anterior-segment image based on an image-pickup signal outputted from the second image-pickup element; mode switching means which generates a mode switching signal for switching between a first measurement mode in which the first eye characteristic of the eye is measured by the first measurement unit and a second measurement mode in which the second eye characteristic of the eye is measured by the second measurement unit; and a control unit which is connected with the up-and-down movement mechanism and the display device, and controls the up-and-down movement mechanism and the display device, wherein the control unit drives and controls the up-and-down movement mechanism based on the mode switching signal generated by the mode switching means to change a state in which the first center axis and the eye are placed at substantially a same height into a state in which the second center axis and the eye are placed at substantially a same height by moving the main body of the apparatus by a distance between the first center axis and the second center axis in the up-and-down direction, and controls to display the image outputted from the first image-pickup element and the image outputted from the second image-pickup element simultaneously on the display device for a predetermined period of time during a shift from the first measurement mode to the second measurement mode based on the mode switching signal generated by the mode switching means.
