Display device, image processing apparatus, control methods thereof, and display system

A projection-type display device that projects an image onto a projection surface using a light source, the device comprising:

• an image input interface that receives the image;
• an information obtainment circuit that obtains information pertaining to optical characteristics of the projection surface;
• and
• a light source controller that controls the light source on the basis of metadata pertaining to a luminance or a color of the image and the information.

A display system comprising:

• a display device;
• and
• an information processing apparatus communicatively connected to the display device,
• wherein the display device is capable of enhancing a dynamic range or a color gamut of a printed material by illuminating the printed material, the display device comprises:
• an image input interface that receives from the information processing apparatus an image for illuminating the printed material;
• an information obtainment circuit that obtains information pertaining to optical characteristics of the printed material;
• and
• a light source controller that controls, on the basis of metadata pertaining to a luminance or a color of the image and the information, a light source that illuminates the printed material, and
• wherein the information processing apparatus sends, to the display device, the image based on an image printed onto the printed material.

A control method of a display device capable of enhancing a dynamic range or a color gamut of a printed material by illuminating the printed material, the method comprising:

• receiving an image for illuminating the printed material;
• obtaining information pertaining to optical characteristics of the printed material;
• and
• controlling, on the basis of metadata pertaining to a luminance or a color of the image and the information, a light source that illuminates the printed material.

A non-transitory computer-readable medium storing a program that causes a computer included in a display device being capable of enhancing a dynamic range or a color gamut of a printed material by illuminating the printed material to function as:

• an image input unit that receives an image for illuminating the printed material;
• an information obtainment unit that obtains information pertaining to optical characteristics of the printed material;
• and
• a light source control unit that controls, on the basis of metadata pertaining to a luminance or a color of the image and the information, a light source that illuminates the printed material.
