Abstract: An overhead-view image generation device includes: a moving amount calculation unit that calculates a moving distance of a vehicle; a linear overhead-view image generation unit that generates an overhead-view image obtained by conversion of a viewpoint of a captured image of a camera into an overhead viewpoint, and generates a linear overhead-view image obtained by conversion of a shape of the generated overhead-view image into a linear shape; a distance-based turning angle generation unit that calculates, using a turning amount of the vehicle indicated by sensor data of a steering angle sensor and the moving distance calculated by the moving amount calculation unit, distance-based turning angle information indicating a turning angle of the vehicle based on the moving distance; and an overhead-view image reconstruction unit that reconstructs the overhead-view image using the linear overhead-view image and the distance-based turning angle information.

Abstract: A visual presenter includes a base having a pivot shaft unit including a shaft support bracket, a support column mounted on the pivot shaft unit so as to be pivotable between a standing position and a forwardly-inclined position, a pivot shaft supported on the bracket, a wave washer inserted through the shaft to be tightened against the bracket by a nut in threading engagement with the shaft, and a return spring attached to the shaft so as to apply a biasing force to the shaft. The braking force and the biasing force counteract a pivotal movement of the support column, and the base includes a counterweight disposed in the base so that the base is prevented from being moved during an operation of pivoting the support column.

Abstract: A visual presenter includes a body including a base and a support column on which an imaging camera is mounted, a stage which is separate from the body and is formed with a placement surface on which a material to be presented is placed, a positioner located on the base, and a positioned member located on the stage so as to be connectable to the positioner so that the placement surface falls within an imaging range of the imaging camera.

Abstract: A visual presenter includes a base including a pivotal shaft support, a support column standing on the pivotal shaft support and having a distal end curved so as to protrude in such a direction that the distal end becomes more distant from the base, and an imaging camera rotatably mounted on the distal end of the support column. The imaging camera includes a casing having both lengthwise ends, an imaging camera body mounted on one lengthwise end of the casing and an operation unit mounted on the other lengthwise end. The pivotal shaft support is biased from a lengthwise center of the casing relative to the support column so that a distance from the support column to the one lengthwise end of the casing on which the imaging camera is mounted is longer than a distance from the support column to the other lengthwise end of the casing.

Abstract: A visual presentation apparatus includes a generally rectangular stage on which a material is placed, a video camera for obtaining an image of the material, a camera arm on which the video camera is mounted so that the video camera is located above a central portion of the stage, and an arm mount provided outside one of corners of the stage. The arm has a proximal end pivotally mounted on the arm mount so that the camera arm is caused to pivot substantially along a diagonal of the stage between a first position where the video camera is located above the central portion of the stage and a second position where the camera arm is folded down along the stage. The video camera is located within the stage when the arm assumes the second position.
