Abstract: A camera body according to the present disclosure is a camera body to which a lens barrel including an optical system is detachable and reattachable, the optical system being configured to include a plurality of lenses. The camera body includes: a controller which controls the camera body; an image sensor which obtains an optical image formed by the optical system; and an image sensor driver which drives the image sensor in an optical axis direction of the optical system. The controller detects optical feature amounts of a plurality of frames in a state where the image sensor is at an identical position in the optical axis direction, detects a frame in which a change amount of an optical feature amount calculated from a plurality of the detected optical feature amounts has exceeded a predetermined threshold, and drives the image sensor driver to move the image sensor from the identical position to a reference position provided in a movable range when there is a plurality of the frames in which the change amount has exceeded the predetermined threshold.

Abstract: The present disclosure provides a display system that includes an acquisition device, a detection device, a display processing device, and a correction processing device. The acquisition device acquires speed information indicating a speed of a moving body. The detection device detects a posture variation amount of the moving body. The display processing device controls a display position of an image based on a reference position and a correction amount. The correction processing device sets the correction amount based on the speed and the posture variation amount. The correction processing device estimates whether or not the correction amount becomes equal to or more than a predetermined amount based on the speed and the posture variation amount, and adjusts the correction amount based on the estimation result.

Abstract: An optical axis changing assembly changes an optical axis of an imaging device to states of k optical axes, so that the optical axis of the imaging device changes from a state of a first optical axis of the imaging device during capturing a first image to a state of a second optical axis displaced in a second direction intersecting a first direction during capturing a second image, to sequentially change the optical axis of the imaging device in a second direction. The imaging device is installed with an installation inclination so that a predetermined optical axis among the k optical axes is inclined at a predetermined angle smaller than an optical axis change angle of the optical axis changing assembly with respect to a direction from an installation position of the imaging device to an imaging target region in a plane including the k optical axes.

Abstract: An autofocus device includes: an imaging element; an imaging element driver; an imaging element driving controller; a detector; a focus determiner; and a speed parameter calculator. The focus determiner detects a focus position based on a contrast value. The speed parameter calculator calculates a speed parameter used to set a driving speed of the imaging element driver based on the contrast value. The imaging element driving controller performs first and second driving controls for detecting the focus position based on the speed parameter in an autofocus operation. Also, the imaging element driving controller sets, during the first driving control, a driving speed of the imaging element driver for the second driving control.

Abstract: A display system includes an attitude detection device configured to detect an attitude change amount of a moving body, and a correction processing device including a vibration detector configured to determine whether or not an attitude change in the moving body having a specific frequency band component has been continuously generated based on the attitude change amount. The correction processing device updates a correction amount of a display position of the image based on the attitude change amount when the vibration detector determines that the attitude change having the specific frequency band component has not been continuously generated, and sets an absolute value of the correction amount to be equal to or less than an absolute value of a correction amount at a time of last determination when the vibration detector determines that the attitude change having the specific frequency band component has been continuously generated.
