Abstract: An image display system includes: an image projection unit that projects and displays an image on a display target for a moving body; a posture angle calculation unit that calculates a posture angle for the moving body on the basis of chronological data for acceleration detection values for the acceleration of the moving body in a prescribed time period; and a display control unit that controls the display position at which the image is projected and displayed on the display target, in accordance with the posture angle calculated by the posture angle calculation unit. The acceleration detection values include bi-directional components. The posture angle calculation unit excludes acceleration detection values from the chronological data used when calculating the posture angle, said acceleration detection values being included in an exclusion time period which has a ratio for the bidirectional components, in the prescribed time period, that is outside a prescribed range.

Abstract: An image display system includes a body, a first correction unit, and a second correction unit. The body houses a display unit to display an image and projects a virtual image, corresponding to the image, onto a target space using outgoing light of the display unit. The first correction unit corrects for distortion of the image. The second correction unit corrects a display location of the image on the display unit in accordance with an orientation signal representing a change in orientation of the body. Each of divisional areas of a display screen of the display unit is assigned with a distortion correction parameter for correcting for the distortion of the virtual image. The first correction unit applies distortion correction to each of the image regions of the image on the display screen based on a distortion correction parameter assigned to a divisional area where the image region is displayed.

Abstract: An information processing system that appropriately estimates a driving conduct includes: a detector that detects a vehicle environment state, which is at least one of surroundings of a vehicle and a driving state of the vehicle; a behavior learning unit configured to cause a neural network to learn a relationship between the vehicle environment state detected by the detector and a behavior of the vehicle implemented after the vehicle environment state; and a behavior estimation unit configured to estimate a behavior of the vehicle by inputting, into the neural network that learned, the vehicle environment state detected at a current point in time by the detector.

Abstract: A rendering system includes a first obtainer, a second obtainer, a renderer, an estimator, and a corrector. The first obtainer obtains position information indicating a position of an object from a detector. The second obtainer obtains movement information indicating a movement state of the moving body. The renderer renders a display image including a content related to the object. The estimator estimates a delay period by comparing the position information to estimated-position information indicating an estimated position of the object estimated based on the movement information of the object. The corrector corrects displacement of a display position of the content on the display image which is caused by movement of the moving body over the delay period.

Abstract: An image display system includes a display unit displaying an image, a projection unit projecting in a target space a virtual image corresponding to the image with an output light of the display unit, a body unit provided thereto the display unit and the projection unit, and an image producing unit including a first correction unit and a second correction unit. The first correction unit performs a first correction processing of correcting, based on a first orientation signal indicative of a first orientation change of the body unit, a display position of the virtual image in the target space. The second correction unit performs a second correction processing of correcting, based on a second orientation signal indicative of a second orientation change of the body unit which is faster than the first orientation change, the display position of the virtual image in the target space.

Abstract: A display correction system includes a first obtainer, a second obtainer, a third obtainer, a predictor, and a corrector. The first obtainer obtains travel route information on a travel route ahead of a moving body. The second obtainer obtains speed information on a speed of the moving body. The third obtainer obtains orientation information on an orientation of the moving body. The predictor predicts, based on the travel route information and the speed information, a time period during which the moving body travels through a specific section in the travel route. The corrector performs correction of a displacement of a display position of a content on a display image based on the orientation information. Based on prediction result of the predictor, the corrector executes first control when the moving body is traveling in a normal section, and executes second control when the moving body is traveling in the specific section.
