Display method and display apparatus

A display apparatus comprising:

• a processor;
• a sensor configured to detect intensity of ambient light;
• and
• a finder provided with a display inside,
• wherein the processor is configured to acquire video data by imaging under the ambient light, create display data based on the video data, and display a display video corresponding to the display data on the display,
• the processor is configured to create the display data or display the display video under a first condition that lightness of the display video displayed on the display is brighter than lightness of a first standard video in a case where the intensity of the ambient light is equal to or greater than a first threshold value or
• the processor is configured to create the display data or to display the display video under a second condition that the lightness of the display video displayed on the display is darker than lightness of a second standard video in a case where the intensity of the ambient light is equal to or less than a second threshold value,
• wherein, before a usage time for which a user uses the finder reaches a set time, the processor is configured to create the display data or to display the display video under the first condition or the second condition, and
• wherein, after the usage time reaches, the processor is configured to create the display data and to display the display video without the first condition and the second condition.

A display method using a display apparatus including a finder provided with a display inside, the display method comprising:

• an acquisition step of acquiring first video data by imaging;
• a creation step of creating a plurality of pieces of second video data indicating different gradation values based on the first video data;
• a display step of displaying a plurality of display videos corresponding to the plurality of pieces of second video data on the display;
• a reminder step of reminding a user of usage of the finder in a case of displaying the plurality of display videos on the display;
• and
• a storage step of storing the second video data corresponding to a display video selected by the user from among the plurality of display videos, in a storage device.

A display method using a display apparatus including a sensor configured to detect intensity of ambient light and a finder provided with a display inside, the display method comprising:

• an acquisition step of acquiring video data by imaging under the ambient light;
• a creation step of creating display data based on the video data;
• and
• a display step of displaying a display video corresponding to the display data on the display,
• wherein, in a case where the intensity of the ambient light is equal to or greater than a first threshold value, the creation step or the display step is executed under a condition that lightness of the display video displayed on the display is brighter than lightness of a first standard video,
• in a case where the intensity of the ambient light is equal to or less than a second threshold value, the creation step or the display step is executed under a condition that the lightness of the display video displayed on the display is darker than lightness of a second standard video,
• wherein, in the creation step, correction corresponding to the intensity of the ambient light is executed on an output value with respect to an input gradation value indicated by the video data to create the display data indicating a corrected output value, and
• wherein a correction amount to the output value in the creation step is changed depending on a distance between a user and the finder or lightness in the finder.
