A communication system () comprises a central () and a peripheral (). The central () receives location information and time information from NTP servers () and a location server (). The central () creates first offset information of the time measured by its own device and the time information received from the NTP servers (). The central () acquires from map information a time difference corresponding to a location presented by the location information received from the location server (). The central () creates first updated time information based on the time measured by its own device, first offset information, and time difference corresponding to the location presented by the location information received from location server () and transmits the first updated time information to the peripheral (). The peripheral () changes the time displayed by its own device based on the received first updated time information.

An image processing unit includes: a gain calculating section obtaining, based on first luminance information for each pixel, a first gain, in which the first gain is configured to increase with an increase in pixel luminance value in a range where the pixel luminance value is equal to or larger than a predetermined luminance value, and in which the pixel luminance value is derived from the first luminance information; and a determination section determining, based on the first luminance information and the first gain, second luminance information for each of the pixels.

Display unit, image processing unit, and display method for improving image quality

A heat sinkis provided on a lower edge side, for example, of a display panelwith a heat radiation surface being on a display surface side of the display panel. A heat source, such as a light source, which generates heat owing to display operation using the display panelis mounted on a mounting face opposite to the heat radiation surface. A coverthat covers the heat sinkis provided on the display surface side of the display panel. Air holesandare formed on a top faceand a bottom face, respectively, of the cover. Air taken in through the air holeson the bottom faceof the covercools the heat sink, and the air heated by the heat of the heat sinkis dissipated outside through the air holeson the top face. Heat generated inside the display device is efficiently dissipated with a small ventilation resistance without generation of noise. Since heat is dissipated on the display surface side, discoloration of wall paper on a mounting face and the like is prevented or reduced.

Display device

According to an aspect of the present invention, a device includes a transmitter and receiver that transmits and receives communication packets to and from other device, and a processor. The processor receives a packet containing first information indicating a structure type of data from the other device via the transmitter and receiver and communicates data corresponding to the first information with the other device via the transmitter and receiver.

Communication device, communication method, and storage medium

According to an aspect of the present invention, a device capable of wireless communication includes a communicator configured to transmit and receive communication packets to and from other device, a memory configured to store one or more kinds of setting information, and a processor configured to determine whether or not at least one of the one or more kinds of setting information has been changed after the last communication with the other device, generate discrimination information indicating whether or not each of the one or more kinds of setting information has been changed, and control communication with the other device based on the discrimination information.

According to an aspect of the present invention, a device capable of wireless communication includes a counter for counting current time, and a processor for setting a communication mode of the device to one of a notification mode in which the device sends a first notification signal for informing of its existence and a detection mode in which the device detects a second notification signal sent from other device. In the case that the processor changes the communication mode of the device from the notification mode to the detection mode and the second notification signal received in the detection mode includes first time information, the processor corrects time of the counter based on the first time information.
