An image processing apparatus comprises: a first generation unit that generates approximate light pattern by adjusting spatial frequency of an input image, and generates a projection image data based on the approximate light pattern; and a second generation unit that generates a print image data based on the input image, wherein the second generation unit generates the print image data so that a difference between the input image and an image for observation obtained by superimposing projection light projected based on the projection image data onto a printed matter printed based on the print image data is reduced.

Image processing apparatus and method, image projection apparatus, printing apparatus, and image printing and projection system

An image display device is provided in which a difference in color appearance between visual angles can be reduced. The image display device includes: a light-emitting unit including a first light source configured such that a peak wavelength of a spectral spectrum of the light source is within a wavelength region in which a difference between color matching functions of different visual angles is small and a second light source that differs from the first light source; a control unit configured to switch a light source to be lighted to one of the first light source and the second light source based on an instruction; and a display panel that is illuminated by the light-emitting unit.

Image display device and control method thereof

A print control unitthat, once it receives a datacasting automatic activation notification or a datacasting manual activation notification, determines whether or not datacasting is present for a currently selected channel. In a case in which datacasting is present, the print control unitacquires maintenance information acquired from a printerthrough a maintenance information acquisition process. Based on the acquired maintenance information, the print control unitdetermines whether or not to issue a command to the printerrequesting execution of a maintenance process.

Digital broadcast receiver and digital broadcast receiver control method

A broadcast receiving apparatus determines whether a broadcast signal that is being played back and that includes print information is a broadcast signal that is being broadcasted or a broadcast signal that is played back by a recording apparatus. The broadcast receiving apparatus also determines whether the print information included in the broadcast signal that is being played back includes acquisition instructing information instructing acquisition of a print content item transmitted from an external server. If it is determined that the print information included in the broadcast signal that is being played back includes the acquisition instructing information and the broadcast signal that is being played back is played back by the recording apparatus, the broadcast receiving apparatus notifies a user that a print content item which the print information included in the broadcast signal that is being played back intended to acquire during broadcasting cannot possibly be acquired.
