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: The present disclosure provides a display system that includes an information acquisition device, a display processing device, a posture detection device, and a correction processing device. The information acquisition device acquires a position of a moving body and information outside the moving body. The display processing device controls display of an image based on information acquired by the information acquisition device. The posture detection device that detects posture variation of the moving body. The correction processing device that sets a correction amount of a display position of the image based on posture variation of the moving body, outputs the correction amount when the display information acquired from the display processing device indicates that the image is being displayed, and reduces size of the correction amount when the display information indicates that the image is not being displayed.

Abstract: A camera body, to which a lens barrel having an optical system can be attached, includes a controller that controls the camera body, an image sensor that captures an object image, and an image sensor actuator that drives the image sensor along an optical axis. The controller determines a change in an optical state of the object image captured by the image sensor and, in response to the determination, drives the image sensor actuator to move the image sensor to a predetermined reference position located within a movable range of the image sensor.

Abstract: A display system includes a display processing device that controls display of an image, a posture detection device that detects a posture change amount of moving body, a correction processing device that sets a correction amount of display position of the image, a display determiner that determines whether or not to display the image, and a gradient change detector that detects a gradient change of a traveling path. The gradient change detector detects that a posture change of the moving body is started when an absolute value of the posture change amount is larger than a first threshold, and that the posture change is completed when the absolute value becomes smaller than a second threshold after start of the posture change. The display determiner determines not to display the image from start of the posture change until completion of the posture change.

Abstract: An imaging system located on a moving body, includes an imaging device, a blur correction device, and an image processor. Based on a subject distance from the imaging device to the object to be imaged, the blur correction device sets a blur correction amount of blur in a movement direction caused when the imaging device captures images during movement of the moving body. The blur correction device corrects blur during image capturing by use of the set blur correction amount. The image processor calculates a pixel movement amount of a feature portion common to a first image and a second image. Based on the pixel movement amount and the movement amount of the moving body, the blur correction device calculates a third distance as the subject distance.
