a first control unit configured to control whether or not to request a change of a display setting of the display according to a correspondence between the display settings of the display and a characteristic of the image; and

a second control unit configured to control image transmission to the display via the interface so that a single image is displayed on the display for at least the display time,

wherein the second control unit, in a case where the first control unit requests a change of a display setting of the display, transmits the image after the change to the display setting in the display is completed.

2 . The image processing apparatus of claim 1 ,

wherein the first control unit further, in a case where a characteristic of a first image that has been displayed in the display and a characteristic of a second image that the display is to be caused to display next differ, configured to request the change of the display setting of the display via the interface so that the display setting of the display and the characteristic of the second image that the display is to be caused to display correspond.

3 . The image processing apparatus of claim 1 ,

wherein the first control unit further, in a case where the display setting of the display when a first image has been displayed and a characteristic of a second image that the display is to be caused to display next do not correspond, configured to request the change of the display setting of the display via the interface so that the display setting of the display and the characteristic of the second image that the display is to be caused to display correspond.

4 . The image processing apparatus of claim 1 ,

wherein the first control unit further, in a case where a characteristic of a first image that has been displayed in the display and a characteristic of a second image that the display is to be caused to display next are the same, configured not to request the change of the display setting of the display,

wherein the second control unit further configured to transmit the image so that a single image is displayed on the display for the display time.

5 . The image processing apparatus of claim 1 ,

wherein the second control unit further, in a case where the display setting of the display when a first image has been displayed and a characteristic of a second image that is to be caused to be displayed in the display next correspond, configured to transmit the image so that a single image is displayed on the display for the display time without changing the display setting of the display.

6 . The image processing apparatus of claim 1 ,

wherein in a case where the first control unit requests the changes of the display setting of the display, the second control unit transmits the image so that a single image is displayed on the display for the display time in response to a notification indicating that the change to the display setting in the display has been completed being received via the interface.

7 . The image processing apparatus of claim 1 ,

wherein in a case where the first control unit requests the change of the display setting of the display, the second control unit transmits the image so that a total of the longest time required for changing the display setting in the display and the display time becomes fixed.

8 . The image processing apparatus of claim 1 ,

wherein the second control unit further acquires, from the display, information indicating the display setting of the display via the interface.

9 . The image processing apparatus of claim 1 , further comprising

a display unit configured to, in a case where a plurality of images are displayed on the display switched by the second control unit, display as a playback time either a total time of display times of respective images not including a time required for changing the display setting in the display or a total time of a time required for changing the display setting in the display and the display time for the plurality of images.

10 . The image processing apparatus of claim 1 , further comprising

a conversion unit configured to convert a characteristic of the image to be transmitted to the display according to the display setting of the display and the characteristic of the image to be transmitted to the display.

11 . The image processing apparatus of claim 10 ,

wherein the second control unit, in a case where the characteristic of the image to be transmitted to the display has been converted by the conversion unit, controls transmits the image such that the converted image is displayed on the display for the display time without changing the display setting of the display.

12 . The image processing apparatus of claim 1 , wherein the characteristic of an image includes a gamma characteristic and an output range.

13 . The image processing apparatus of claim 1 , further comprising a determination unit configured to determine whether or not a change of the display setting of the display is necessary based on a characteristic of an image to be caused to be displayed on the display and information of the display setting of the display.

14 . The image processing apparatus of claim 1 , wherein the second control unit transmits the image to the display and determines whether or not the display time has elapsed since the start of the transmission.

15 . The image processing apparatus of claim 1 , wherein the display setting of the display includes an electro-optical transfer function set in the display and information of a tone range.

16 . A method of controlling an image processing apparatus with an interface for transmitting an image that a display is to be caused to display, the method comprising:

setting a display time corresponding to a length of time that the display is to be caused to display a single image;

acquiring a display setting of the display via the interface;

controlling whether or not to request a change of a display setting of the display according to a correspondence between the display settings of the display and a characteristic of the image; and

controlling image transmission to the display via the interface so that a single image is displayed on the display for at least the display time,

wherein the control includes, in a case where a change of a display setting of the display is requested, transmitting the image after the change to the display setting in the display is completed.

17 . A non-transitory computer-readable storage medium comprising instructions for performing a method of controlling an image processing apparatus with an interface for transmitting an image that a display is to be caused to display, the method comprising:

setting a display time corresponding to a length of time that the display is to be caused to display a single image;

acquiring a display setting of the display via the interface;

controlling whether or not to request a change of a display setting of the display according to a correspondence between the display settings of the display and a characteristic of the image; and

controlling image transmission to the display via the interface so that a single image is displayed on the display for at least the display time,

wherein the control includes, in a case where a change of a display setting of the display is requested, transmitting the image after the change to the display setting in the display is completed.
