    摘要: An information processing device which controls one projector and another projector includes: a display unit which displays a first operation screen for managing the one projector and a second operation screen for managing the another projector; an input unit which accepts an operation on the first operation screen and the second operation screen; and a control unit which controls the one projector and the another projector, based on the operation accepted by the input unit. When the information processing device is switched from a first state where the first operation screen is operable to a second state where the second operation screen is operable, the control unit causes the second operation screen where an item corresponding to a predetermined item selected on the first operation screen in the first state is selected, to be displayed in the second state.

    摘要: A display device and a method for controlling same are provided which are capable of suppressing power consumption of an electronic apparatus while supplying a user with various types of information in various display formats. The display device has a first display block including a processor with relatively high processing power and a display section with high display performance and a second display block including a processor with relatively low processing power and a display section with low display performance. The processors mutually collaborate and are controlled to properly use the first display block and the second display block in accordance with an operation mode.

    摘要: Provided is a display device capable of reliably moving a micromirror to a parking position when operation is stopped. A head-up display device drives a DMD element on the basis of electric power from a battery power supply. The head-up display device is provided with: a DMD controller for performing control of the DMD element on the basis of the electric power from the battery power supply; a voltage monitoring circuit for monitoring the voltage of the battery power supply; and a backup power supply for supplying power to the DMD controller as a backup of the battery power supply. When the voltage of the battery power supply which has been monitored by the voltage monitoring circuit falls to or below a threshold value, the DMD controller moves the DMD element to the parking position on the basis of the electric power from the backup power supply.
