Sharp NEC Display Solutions, Ltd.

A display system includes a category determination unit configured to determine a category on the basis of a result of estimating attributes of a person included in an image captured within a visible range of a display screen of a display device that displays content. The display system also includes a display control unit configured to cause the display device to display a list of the content, which is generated according to the category based on a viewing tendency of the content.

The invention includes a camera that captures an image of a user, a first estimation unit that estimates attributes of the user included in the image captured by the camera, an extraction unit that extracts candidates from among services corresponding to the estimated attributes on the basis of an availability status of each service time frame, and a display control unit that displays the extracted candidates on a display screen.

A display device includes a display processing unit configured to display character input buttons, each of which is assigned a plurality of characters, and an order designation button for designating the order of a character capable of being input among the characters assigned to the character input button, an order designation unit configured to designate the order of the character capable of being input among the characters assigned to the character input button every time a button corresponding to the order designation button among buttons on an operation terminal is pressed, and an input character acquisition unit configured to acquire the character corresponding to the order designated by the order designation unit among the characters assigned to the character input button corresponding to the pressed button as an input character when the button corresponding to the character input button among the buttons on the operation terminal is pressed.

Disclosed is a light source driving device ( 20 ) for driving a plurality of light emitting element groups in a light source device that outputs combined light obtained by combining light emitted from the light emitting element groups, the light source driving device including a control circuit ( 201 ) that supplies a current that alternately repeats a first period in which a first current is supplied and a second period in which a second current having a current value different from a current value of the first current is supplied to the plurality of light emitting element groups, the second current being supplied to a second light emitting element group in a case where the first current is being supplied to a first light emitting element group, and the first current being supplied to the second light emitting element group in a case where the second current is being supplied to the first light emitting element group, wherein a target value of a light intensity obtained by the combined light is a light intensity that is higher than a light intensity obtained in a case where a current having a rated value is applied to any one of the light emitting element groups, and wherein a total of the current value of the first current and the current value of the second current is greater than the rated value.

A signal processing system includes: a first device to receive a control signal from an external device; a second device connected to the first device and to control a control target device; and a first storage medium connected to the first and second devices. The first device includes a first processor to output the control signal to the second device and a second storage medium connected to the first processor via a first internal communication path. The second device includes a second processor to control the control target device based on the control signal and a third storage medium connected to the second processor via a second internal communication path. The first storage medium is connected to the first and second internal communication pathes. The first storage medium stores the control signal input via the first internal communication path, and outputs the control signal via the second internal communication path.

A projection display device includes a light source, a reflection mirror that has a reflecting surface reflecting light emitted from the light source in a predetermined direction, a light receiving sensor that detects an output of the light having passed through the reflection mirror, and an opening member that is provided between the reflection mirror and the light receiving sensor and has an opening through which the light having passed through the reflection mirror passes. The opening member is positioned on an optical axis of the light that passes through the reflection mirror. The opening of the opening member is positioned to be misaligned from the optical axis of the light that passes through the reflection mirror.

An information processing device includes a first display control unit configured to display together first content and second content, which is different from the first content, together, in a display area of a display unit. The information processing device further includes an identification unit configured to identify third content and fourth content on the basis of a viewing action for the first content and the second content. The information processing device further includes a second display control unit configured to display, in the display area, the third content as identified and the fourth content as identified. A degree of relevance between the third content and the fourth content is lower than a degree of relevance between the third content and the first content.

A video input terminal inputs a video signal. A video output terminal outputs the video signal input to the video input terminal. A communication terminal performs one-to-one communication with each of a plurality of display devices. A communication controller notifies each of the plurality of display devices of a control command including control information for issuing an instruction to execute a specific process by switching a destination of communication via the communication terminal and additional information indicating a waiting time before a process corresponding to the control information is executed.

A projection display device includes a light source; and an optical system unit configured to process a light from the light source and to emit the light outside the projection display device. The optical system unit includes an outer shell member having an emission opening positioned at a position from which the light is emitted; and a transparent member disposed at the emission opening of the outer shell member at the emission opening. The transparent member is retained at a retention temperature which is higher by 1° C. or more than an inner-wall temperature of the outer shell member after a light source has been turned off.

A content management unit acquires a waiting time when a user waits to charge an in-vehicle battery, extracts candidate facilities available to the user in accordance with the acquired waiting time. The content management unit acquires surrounding environment information indicating an environment around the facility for charging the in-vehicle battery. The content management unit selects at least one candidate facility from the candidate facilities in accordance with the acquired surrounding environment information. The content management unit identifies presentation content related to the selected candidate facility. A display processing unit displays the presentation content identified by the content management unit.
