Abstract: A control apparatus includes a control unit that adjusts at least one of a color and luminance of a projection image for each group of the plurality of projection apparatuses based on information on the group and a captured image obtained by imaging projection images of the plurality of projection apparatuses using the pickup apparatus. The control unit acquires each of positions of a plurality of projection areas of the plurality of projection apparatuses based on the captured image, and generates, as the information on the group, information indicating that two projection apparatuses corresponding to a first projection area and a second projection area belong to the same group in a case where a distance between the first projection area and the second projection area among the plurality of projection areas is smaller than a predetermined threshold.

Abstract: A projection control apparatus is configured to control a first image projection apparatus that projects a first image and a second image projection apparatus that projects a second image so that the first image and the second image are superimposed on each other in a predetermined area. The projection control apparatus includes a corrector configured to correct an imaging characteristic for converting a received light amount into captured image data in an imaging apparatus configured to capture the first and second images, by using a pixel value of the predetermined area in the captured image data obtained from the imaging apparatus, and a controller configured to control at least one of the first and second image projection apparatuses using a corrected imaging characteristic.

Abstract: A pitch angle in the back-and-forth direction of the vehicle body is calculated based on output signals of height sensors disposed at front and rear wheels of the vehicle. A vehicle traveling speed is obtained. A vehicle acceleration is obtained from the vehicle traveling speed. Using the vehicle traveling speed and the vehicle acceleration, a judgement is made to determine the control mode corresponding to the vehicle traveling condition, by selecting one from the group consisting of a stopping mode, an acceleration mode, a deceleration mode and a constant-speed mode. An actuator target value (i.e., target aiming adjustment angle) is calculated in accordance with the determined control mode. To obtain this actuator target value, a filter is used to process the pitch angle so that the headlights do not dazzle an oncoming vehicle's driver. Then, the aiming adjustment for the headlights is performed by actuating actuators in accordance with the actuator target value.
