Display control apparatus and display control method

A display control apparatus comprising at least one processor that operates as:

• an obtaining unit configured to obtain average luminance information representing a maximum period average luminance value which is a maximum value of average luminance in target image data in each frame in a first period including a plurality of frames and first maximum luminance information representing first maximum period luminance which is maximum luminance in target image data in the first period;
• and
• a setting unit configured to set one of a first control mode for displaying an image based on the target image data at a display unit with carrying out power limiting processing for reducing display luminance of each frame so that power consumption by the display unit is equal to or less than a predetermined power threshold value and a second control mode for displaying the image at the display unit without carrying out the power limiting processing, wherein
• the setting unit sets the first control mode in a case where the first maximum period luminance is equal to or less than predetermined upper limit display luminance and the maximum period average luminance value is equal to or less than first upper limit average display luminance.

A display control method comprising:

• an obtaining step of obtaining average luminance information representing a maximum period average luminance value which is a maximum value of average luminance in target image data for each frame in a first period including a plurality of frames;
• and
• a setting step of setting one of a first control mode for displaying an image based on the target image data at a display unit with carrying out power limiting processing for reducing display luminance of each frame so that power consumption by the display unit is equal to or less than a predetermined power threshold value and a second control mode for displaying the image at the display unit without carrying out the power limiting processing, wherein
• in the setting step, the second control mode is set in a case where the maximum period average luminance value is higher than a first threshold value on the basis of the average luminance information.
