Abstract: A controller for a 3D observation apparatus performing 3D observation based on parallax using a plurality of optical systems includes the following sections. A start time acquisition section obtains a start time when energization of the 3D observation apparatus is started. An interrupted time acquisition section obtains an interrupted time when previous energization of the 3D observation apparatus is interrupted. A non-active time calculation section calculates a non-active time which is a period of time between the interrupted time and the start time. A determination section determines whether or not misalignment correction to correct misalignment of optical axes of the optical systems is necessary based on the non-active time.

Abstract: An image pickup system includes a stereoscopic endoscope including image pickup optical systems having a parallax therebetween and a first image pickup device and a second image pickup device, and a processor including a first photometric measurement section configured to photometrically measure a luminance value of a first image pickup signal related to the first image pickup device, a second photometric measurement section configured to measure a luminance value of a second image pickup signal related to the second image pickup device, and a control section including a threshold value comparison section configured to compare the luminance value with a threshold value. When the luminance value of either one of the first image pickup signal and the second image pickup signal exceeds the threshold value, the image pickup system performs light adjustment control of a light source based on a photometric value of the other image pickup signal.

Abstract: An endoscope system includes a processor configured to generate a clock at predetermined timing, a light source apparatus configured to irradiate white light and excitation light in a time division manner in synchronization with the clock, and an endoscope configured to perform image pickup based on irradiation timing of the light source apparatus. The processor generates a first white light image at a first clock, generates a first fluorescent image at a second clock, generates a second white light image at a third clock, and generates a third white light image at a fourth clock and superimposes the second white light image and the first fluorescent image at the fourth clock and superimposes the third white light image and the first fluorescent image at a fifth clock.

Abstract: An endoscope system is provided with: a processor; a light source; and an image pickup device. The processor performs control for causing reflected light images corresponding to a predetermined period before start of the fluorescence occurrence period during the fluorescence non-occurrence period, among the reflected light images, to be recorded to the first storage medium; and, furthermore, performs control for causing the reflected light images to be recorded to the first storage medium during an after-end-of-fluorescence-occurrence period corresponding to a predetermined period with an end of the fluorescence occurrence period as a start point, and performs control for causing the reflected light images not to be recorded to the first storage medium during the fluorescence non-occurrence period after an end of the after-end-of-fluorescence-occurrence period.
