Image processing apparatus and display apparatus

A display apparatus, comprising:

• a determining unit configured to determine, based on a brightness characteristic value of input image data, a correspondence relationship between a display brightness of a display unit and a brightness of the input image data;
• the display unit configured to display an image based on the input image data in accordance with the correspondence relationship determined by the determining unit;
• and
• an outputting unit configured to output brightness information related to the correspondence relationship determined by the determining unit, to the display unit or to the outside.

An image processing apparatus, comprising:

• a first acquiring unit configured to acquire moving image data;
• a second acquiring unit configured to acquire, for each frame of the moving image data acquired by the first acquiring unit, brightness information related to a first correspondence relationship that is a correspondence relationship between a display brightness of a first display unit and a brightness of the moving image data;
• a third acquiring unit configured to acquire, for each frame, a brightness characteristic value of the moving image data from the moving image data;
• a determining unit configured to determine, for each frame, a second correspondence relationship that is a correspondence relationship between a display brightness of a second display unit and the brightness of the moving image data based on the brightness characteristic value acquired by the third acquiring unit;
• a fourth acquiring unit configured to acquire, for each frame, a result of a determination on whether or not the second display unit is capable of displaying an image based on the moving image data with a same display brightness as the display brightness of the first display unit;
• and
• a correcting unit configured to correct, for each frame, the second correspondence relationship based on the result of the determination so that a manner of change in the second correspondence relationship between the frames approaches a manner of change in the first correspondence relationship between the frames.

An image processing method, comprising:

• a determining step of determining a parameter to be used in predetermined image processing in accordance with an operation that is performed by a user after an image based on target image data is displayed on a display unit;
• a generating step of generating processed image data by applying the predetermined image processing using the parameter determined by the determining step to the target image data;
• an acquiring step of acquiring brightness information related to a correspondence relationship between a display brightness of the display unit and a brightness of the processed image data;
• and
• a recording step of recording, in a storage unit, the processed image data generated by the generating step and the brightness information acquired by the acquiring step.

A method for controlling a display apparatus having a display unit configured to display an image based on input image data, the method comprising:

• a determining step of determining, based on a brightness characteristic value of the input image data, a correspondence relationship between a display brightness of the display unit and a brightness of the input image data;
• and
• an outputting step of outputting brightness information related to the correspondence relationship determined by the determining step, to the display unit or to the outside, wherein
• the display unit displays the image based on the input image data in accordance with the correspondence relationship determined by the determining step.

An image processing method, comprising:

• a first acquiring step of acquiring moving image data;
• a second acquiring step of acquiring, for each frame of the moving image data acquired by the first acquiring step, brightness information related to a first correspondence relationship that is a correspondence relationship between a display brightness of a first display unit and a brightness of the moving image data;
• a third acquiring step of acquiring, for each frame, a brightness characteristic value of the moving image data from the moving image data;
• a determining step of determining, for each frame, a second correspondence relationship that is a correspondence relationship between a display brightness of a second display unit and the brightness of the moving image data based on the brightness characteristic value acquired by the third acquiring step;
• a fourth acquiring step of acquiring, for each frame, a result of a determination on whether or not the second display unit is capable of displaying an image based on the moving image data with a same display brightness as the display brightness of the first display unit;
• and
• a correcting step of correcting, for each frame, the second correspondence relationship based on the result of the determination so that a manner of change in the second correspondence relationship between the frames approaches a manner of change in the first correspondence relationship between the frames.
