A display management device includes an acquisitioner and a data processor. The acquisitioner acquires occupancy request information from a first terminal. The occupancy request information indicates that a request is made to display content on a plurality of displays positioned in a first region. When the acquisitioner acquires the occupancy request information, the data processor generates a available time display data using a display information storage and transmits same to the first terminal. The display information storage stores information relating to available time of the plurality of displays positioned in the first region. The available time display data is data for displaying a screen which shows availability information including the number of displays which can be reserved and/or the occupancy rate thereof for each time period.

Display management device, display management method, and program

A display system includes: a plurality of secondary display units that respectively display a plurality of videos; a primary display unit that displays at least one of the plurality of videos; a detection unit that detects a number of viewers of each of the plurality of secondary display units; and a control unit that causes the primary display unit to display a same video as the video being displayed by the secondary display unit having a highest number of viewers among the plurality of secondary display units, based on the numbers of viewers detected by the detection unit.

Display system, display method, and program

A display system includes a main display unit configured to display a video; a plurality of subordinate display units configured to display a plurality of videos, respectively; a detection unit configured to detect the number of viewers of the main display unit and the respective numbers of viewers of the plurality of subordinate display units; and a control unit. The control unit is configured to switch a video displayed on a subordinate display unit of the plurality of subordinate display units to the same video as a video displayed on the main display unit when the number of viewers of the main display unit detected by the detection unit is equal to or more than a first predetermined value and the number of viewers of the subordinate display unit is less than a second predetermined value.

Unnecessary flare correction at the boundary between a blanking area and video signal area is suppressed. An image quality improving apparatus includes 2-dimensional low-pass filter circuitthat extracts low-frequency components from an input video signal; subtractor circuitthat obtains high-frequency components by subtracting the low-frequency components extracted by 2-dimensional low-pass filter circuitfrom the input video signal; and adder circuitthat adds the high-frequency components obtained by subtractor circuitas a correction signal to the input video signal. The input video signal contains blanking signals without any video information. 2-dimensional low-pass filter circuitstarts extraction of the low-frequency components after a lapse of a predetermined unit time from when the input video signal changed from the blanking signal to the signal that contains the video information.

Apparatus and method for geometric distortion correction in video signals

A field delay circuit aligns the phases of two field signals. An average value calculation circuit generates an average value signal of the two field signals. This average value signal can be regarded as a signal that has undergone a one-dimensional low-pass filter process in the row direction in which the number of taps for a progressive signal is 2 and the filter coefficient for each tap is 0.5 and that has then been thinned to one-half the data. A two-dimensional LPF circuit subjects this average value signal to a low-pass filter process and eliminates the high-frequency components (edge components). A subtraction circuit subtracts the average value signal that has undergone the LPF process from each field signal and thus extracts the edge components of each field signal. An amplification circuit multiplies the edge components of each field signal by a prescribed factor. An addition circuit adds the resulting amplified edge components to each field signal.

Picture quality improvement device and picture quality improvement method

An average value signal of the G two-phase input signal is generated by means of an average value calculation circuit. This average value signal is regarded as a signal in which a one-dimensional low-pass filter process, in which the number of taps is 2 and the filter coefficient for each tap is 0.5, has been carried out for a single-phase signal and the number of items of data then thinned to one half. A two-dimensional LPF circuit next subjects this average value signal to a low-pass filter process to eliminate the high-frequency component (edge component). The average value signal that has undergone the low-pass filter process is then subtracted from the input signal of each phase to extract the edge component of the input signal of each phase. An amplification circuit then multiplies the edge component of the input signal of each phase by a prescribed factor, and an addition circuit next adds this multiplied edge component to the input signal of each phase. The above-described processes emphasize the edges of a video picture that is realized by a two-phase signal and thus realize flare correction.
