Image display apparatus and control method therefor

A control method for an image display apparatus connected to an imaging apparatus, the image display apparatus including a display module configured to display an image and a fan configured to rotate to cool the display module, the method comprising the steps of:

• an acquiring step of acquiring an ambient temperature of the display module;
• and
• a controlling step of controlling a speed of rotation of the fan,
• wherein, in response to acquisition, by the controlling step, of a signal corresponding to a recording instruction given by the imaging apparatus, the controlling step controls the speed of rotation the fan from a first speed of rotation to a second speed of rotation lower than the first speed of rotation, and
• wherein, in response to a lapse of a first period determined based on the ambient temperature, the controlling step controls the speed of rotation of the fan from the second speed of rotation to a third speed of rotation higher than the second speed of rotation.

An image display apparatus comprising:

• a display module configured to display an image;
• a fan configured to rotate to cool the display module;
• a sensor configured to detect a value corresponding to a temperature of the display module;
• and
• a control unit configured to control a speed of rotation of the fan, wherein,
• in response to an input of a predetermined instruction to the control unit, the control unit determines a first period based on the detected value and decreases the speed of rotation of the fan from a first speed of rotation to a second speed of rotation, wherein
• in response to a lapse of the first period after decreasing the speed of rotation of the fan, the control unit increases the speed of rotation of the fan from the second speed of rotation to a third speed of rotation.

A control method for an image display apparatus including a display module configured to display an image, a fan configured to rotate to cool the display module, and a sensor configured to detect a value corresponding to a temperature of the display module, the method comprising the steps of:

• acquiring the value from the sensor, and
• controlling the speed of rotation the fan based on the value acquired, wherein
• in response to an input of a predetermined instruction to the image display apparatus, determining a first period determined based on the detected value and decreasing the speed of rotation the fan from a first speed of rotation to a second speed of rotation, and
• in response to a lapse of the first period after the decreasing the speed of rotation of the fan, increasing the speed of rotation of the fan from the second speed of rotation to a third speed of rotation.
