[Object] To provide a technology that enables one user to appropriately recognize a tactile sensation based on a force from the other user. [Solving Means] A tactile presentation apparatus according to the present technology includes a first detection unit, a first presentation unit, and a control unit. The first detection unit detects a first detection value based on a force of a first user. The first presentation unit is provided at a position other than a position of the first detection unit and presents a tactile sensation to the first user. The control unit controls the first presentation unit to present a tactile sensation to the first user on the basis of a second detection value of another tactile presentation apparatus, the other tactile presentation apparatus including a second detection unit that detects a second detection value based on a force of a second user and a second presentation unit that presents a tactile sensation to the second user.

Tactile presentation apparatus, tactile presentation system, tactile presentation control method, and program

A display apparatus of the present disclosure includes: an image detection unit that determines whether an empty second subframe is present in input image data, in addition to a first subframe that displays an image; a correction image generation unit that generates correction image data for correcting the input image data; a control unit that performs control to display the correction image data generated by the correction image generation unit during the period of the second subframe, when the image detection unit detects that the second subframe is present in the input image data; and a display panel that includes a light modulation device provided for each pixel, and modulates irradiation light from a light source, on the basis of input image data including the correction image data.

Display apparatus, method for controlling display apparatus, and projection system

Provided is a spatial light modulator device that includes a light modulation unit, a first memory, and a second memory. The light modulation unit performs a transition operation between a first state and a second state. In the first memory, data for specifying which one state of the first state and the second state the light modulation unit is to be put in is written during a transition time in which the transition operation is performed. In the second memory, the data retained in the first memory is written after the transition time ends and the second memory supplies the data to the light modulation unit.

Spatial light modulator system, spatial light modulator device, and display apparatus for preventing influences of mechanical operations of a light modulation unit

A display unit includes: a display section having an electrophoretic display device provided among a plurality of first electrodes and a second electrode, and displaying an image by switching a white, black, or gray-scale display state depending on an applied voltage; and a drive circuit driving the display section by varying a voltage applied to the first electrodes, while holding the second electrode at a common potential during a write period including frame period(s). When a first region of the display section has a first display state of white or black during a first write period, and an image of a second region thereof is changed while holding the first display state at the first region upon switchover from the first write period to a temporally-continued second write period, the drive circuit offsets the common potential toward a direction in which a voltage applied to the first region is raised.

Display unit, method of driving display unit, and electronic apparatus

A display unit includes a plurality of pixels arranged in a two-dimensional matrix. An image is displayed in a first display mode and a second display mode. In the first display mode, one pixel is configured of a set including J (where J is an integer of 2 or more) first unit pixels emitting a first color, J second unit pixels emitting a second color, and J third unit pixels emitting a third color, and image display is performed through control of operation of each of the unit pixels. In the second display mode, one pixel is configured of a set including j (where j is an integer of 1 or more and less than J) first unit pixels, j second unit pixels, and j third unit pixels, and image display is performed through control of operation of each of the unit pixels.
