Abstract: A system includes a projector, an HMD, and a control device. A detection unit detects a first range and a second range when a user visually recognizes a first display image through the HMD, the first range being a range of the first display region overlapping with a second display region in which the HMD displays a second display image, the second range being a range of the first display image corresponding to the first range. A generation unit generates the first display image including an object and the second display image including the object. The control device generates the first display image by arranging, at a position within the second range corresponding to a position of the second display region for displaying the object, the object having a display size corresponding to a distance between the first display region and the HMD.

Abstract: In an electro-optical device, pixel circuits are provided corresponding to an intersection between a scanning line in an i-th row and a data line in a k-th column in a display region, and an intersection between a scanning line and data line. The pixel circuit is brought into an optical state in accordance with a voltage of a data line when a scanning line is selected. In an odd frame period, in the i-th row selection period and the (i+1)-th row, a data signal of a voltage corresponding to the i-th row and k-th column of data of the top image is output, and in an even frame period, in the i-th row selection period and the (i+1)-th row, a data signal of a voltage corresponding to the (i+1)-th row and the k-th column of data of the bottom image is output.
