摘要： A projector includes a light source; a spatial light modulator; a signal processing unit that includes a tone map unit that performs a luminance gradation conversion of an input video data according to a tone map indicating a relationship of an output luminance with respect to an input luminance; a luminance acquiring unit that obtains a maximum luminance of a projection surface of the modulated light; and a control unit that controls an amount of light of the light source and sets the tone map. When the maximum luminance of the projection surface is equal to or greater than a first threshold value indicating a maximum luminance of the input video data, the control unit sets, to the tone map unit, a tone map in which a maximum value of the output luminance is set to be the first threshold value.

摘要： A display device includes a display panel including a display screen for displaying an image, and a terminal detection unit. When the terminal detection unit detects that a portable information terminal is arranged on the display screen, the display device transmits a data area generation instruction to secure a data area to a storage device to cause the storage device to secure the data area. The display device receives information indicating a location of the data area from the storage device. The display device causes the display screen to display a storage location image including the information indicating the location of the data area on a part of the display screen on which the portable information terminal is arranged, and notifies the portable information terminal of the location of the data area through the storage location image.
