Abstract
A display device receives, from an external device, information set on a settings screen that is displayed on the external device and that allows settings in ranges wider than ranges settable on a settings screen constituting a part of a projected image. The display device then changes settings in accordance with the received information. As a result, a degree of freedom in adjustment of the projected image can be increased.
Claims30
A display device that displays an image comprising:
- a display,
- a communication interface to communicate with an external device,
- an input device to input an instruction by a user, and
- at least one processor to perform a method comprising:
- receiving information from the external device via the communication interface;
- receiving the instruction inputted by a user;
- setting a setting value for an image processing based on at least one of the information and the instruction, and
- performing the image processing to an image to be displayed on the display based on the setting value,
- wherein
- a first range in which a parameter is settable by the setting based on the information is wider than a second range in which a parameter is settable by the setting based on the instruction.
A method of controlling a display device that displays an image, comprising:
- receiving information from an external device via a communication device, wherein the information has been set on a first settings screen displayed by the external device;
- and
- determining a setting of the display device in accordance with the information,
- wherein the first settings screen allows settings within a first range that is wider than a second range settable on a second settings screen included in the image displayed on the display device.
A display device that displays an image by projecting the image, the display device comprising:
- a communication interface to communicate with an external device;
- an input device to input an instruction by a user, and
- at least one processor to perform a method comprising:
- receiving information that has been set on a first settings screen displayed on the external device from the external device via the communication interface, and changing settings in accordance with the received information, the first settings screen allowing settings within first ranges that are wider than the second ranges within which settings based on the instruction are allowed;
- and
- when settings that are not included in the second ranges are configured in accordance with the information, displaying a warning screen by projecting the warning screen, or transmitting data for displaying the warning screen on the external device to the external device via the communication interface.
A method of controlling a display device that includes a communication device that communicates with an external device and an operation unit that configures settings based on a second settings screen that allows settings within second ranges, the method comprising:
- receiving information that has been set on a first settings screen displayed on the external device from the external device via the communication device, the first settings screen allowing settings within first ranges that are wider than the second ranges;
- changing settings in accordance with the received information;
- and
- when the information indicates settings that are not included in the second ranges, either displaying a warning screen, or transmitting data for displaying the warning screen on the external device to the external device via the communication device.
A non-transitory computer-readable medium having stored therein a program for causing a computer included in a display device that displays an image and comprises a communication device that communicates with an external device to function to:
- receive information from the external device via the communication device, wherein the information has been set on a first settings screen displayed by the external device;
- and
- determine a setting of the display device in accordance with the information,
- wherein the first settings screen allowing settings within a first range that is wider than a second range settable on a second settings screen included in an image displayed on the display device.
A non-transitory computer-readable medium having stored therein a program for causing a computer included in a display device that displays an image by projecting the image and comprises a communication device that communicates with an external device and an operation device that configures settings based on a second settings screen that allows settings within second ranges, to
- receive information that has been set on a first settings screen displayed on the external device from the external device via the communication device;
- change settings in accordance with the received information, the first settings screen allowing settings within first ranges that are wider than the second ranges;
- and
- when settings that do not included in the second ranges are configured in accordance with the information, display a warning screen by projecting the warning screen, or transmit data for displaying the warning screen on the external device to the external device via the communication device.
An electronic device that controls a display device that sets a setting value and performs an image processing to an image to be displayed on the display device based on the setting value, comprising:
- a display that displays an image;
- a communication interface configured to communicate with the display device;
- an input device to input an instruction for setting the setting value;
- and
- at least one processor that performs a method comprises:
- displaying a first settings screen on the display for inputting the instruction by user, and
- transmitting, via the communication interface, an information set based on the instruction on the first settings screen to the display device to cause the display device to set a setting value based on the information, wherein
- a first range in which a parameter is settable by the electronic device is wider than a second range in which a parameter is settable by the display device.
A non-transitory computer-readable medium having stored therein a program executable by a computer included in an electronic device, wherein the electronic device controls a display device that sets a setting value, performs an image processing to an image to be displayed on the display device based on the setting value, and comprises:
- a display that displays an image;
- a communication interface configured to communicate with the display device;
- and
- an input device to input an instruction for setting the setting value,
- wherein the program, when executed by the computer, causes the computer to perform:
- displaying a first settings screen on the display for inputting the instruction by user, and
- transmitting, via the communication interface, an information set based on the instruction on the first settings screen to display device cause the display device to set a setting value based on the information, wherein
- a first range in which a parameter is settable by the electronic device is wider than a second range in which a parameter is settable by the display device.
