1. An electronic apparatus comprising: a first electro-optic device that includes a first display region; a second electro-optic device that includes a second display region; a control device that controls a display position of a first image displayed in the first display region and a display position of a second image displayed in the second display region; and a combining device that combines the first and second images, wherein the first electro-optic device includes m 1 scanning lines (where m 1 is an integer equal to or greater than 3) that are disposed in the first display region, and a first scanning line driving circuit that performs a scanning to sequentially select the m 1 scanning lines k by k (where k is an integer equal to or greater than 2), wherein the second electro-optic device includes m 2 scanning lines (where m 2 is an integer equal to or greater than 3) that are disposed in the second display region, and a second scanning line driving circuit that performs the scanning to sequentially select the m 2 scanning lines k by k, wherein the control device includes a supply unit that supplies a first start pulse signal, a first clock signal used to shift the first start pulse signal, and a first enable signal logically combined with a signal shifted using the first clock signal to the first scanning line driving circuit and supplies a second start pulse signal, a second clock signal used to shift the second start pulse signal, and a second enable signal logically combined with a signal shifted using the second clock signal to the second scanning line driving circuit, and a control unit that shifts a phase of the second start pulse signal by half of one horizontal scanning period of the scanning, shifts a phase of the second clock signal by the half of the horizontal scanning period of the scanning, and shifts a phase of the second enable signal by one horizontal scanning period of a line group scanning, when the display position of the second image is shifted by one scanning line.
