Abstract
A display apparatus includes a display unit that displays an image based on an input image and a display control unit that controls the display unit based on the input image. The display control unit controls the display unit in such a manner as to display a value indicative of specific luminance as display luminance in which pixels with predetermined pixel values of the input image are displayed on the display unit.
Claims20
A display apparatus, comprising:
- a display device;
- and
- at least one processor to perform operations as:
- a generating unit configured to generate a second image by converting a dynamic range of a first image into a display range as a dynamic range to be displayed on the display device;
- a setting unit configured to set the display range and a maximum luminance value of the display device, based on a user operation;
- an acquisition unit configured to acquire a value indicative of a specific luminance, based on the display range and the maximum luminance value, the specific luminance being luminance in which at least one pixel corresponding to a target brightness level of the first image is displayed on the display device;
- and
- a control unit configured to control the display device to display a graphical user interface (GUI) image for setting, by a user, the display range and the maximum luminance value of the display device, and to display a value indicative of the target brightness level and the value indicative of the specific luminance.

A control method of a display device, the method comprising:
- generating a second image by converting a dynamic range of a first image into a display range as a dynamic range to be displayed on the display device;
- setting the display range and a maximum luminance value of the display device, based on a user operation;
- acquiring a value indicative of a specific luminance, based on the display range and the maximum luminance value, the specific luminance being luminance in which at least one pixel corresponding to a target brightness level of the first image is displayed on the display device;
- and
- controlling the display device to display a graphical user interface (GUI) image for setting, by a user, the display range and the maximum luminance value of the display device, and to display a value indicative of the target brightness level and the value indicative of the specific luminance.

A non-transitory recording medium storing a program of instructions for causing a computer to perform a method comprising:
- generating a second image by converting a dynamic range of a first image into a display range as a dynamic range to be displayed on a display device;
- setting the display range and a maximum luminance value of the display device, based on a user operation;
- acquiring a value indicative of a specific luminance, based on the display range and the maximum luminance value, the specific luminance being luminance in which at least one pixel corresponding to a target brightness level of the first image is displayed on the display device;
- and
- controlling the display device to display a graphical user interface (GUI) image for setting, by a user, the display range and the maximum luminance value of the display device, and to display a value indicative of the target brightness level and the value indicative of the specific luminance.

A display apparatus comprising:
- a display device;
- and
- at least one processor to perform operations as:
- a first controlling unit configured to control the display device to display a graphical user interface (GUI) image for setting, by a user, a display range of the display device and a maximum luminance value of the display device;
- an acquiring unit configured to acquire a specific luminance, based on (1) a reference brightness level, (2) the display range of the display device and (3) the maximum luminance value of the display device, the specific luminance being luminance with which at least one pixel corresponding to the reference brightness level is displayed on the display device;
- and
- a second controlling unit configured to control the display device to display the reference brightness level and the specific luminance, in text format.
