Electronic device, control method thereof, and storage medium for setting exposure control parameter

A control method of an electronic device, comprising:

• setting a setting value for at least one exposure control parameter among aperture, shutter speed, and ISO sensitivity in 1/n-stop increments (where n is an integer greater than or equal to 8);
• carrying out control so that the setting value for the exposure control parameter set in 1/n-stop increments is displayed as a numerical value in one-stop increments and a fraction serving as a stop expression indicative of a stop that is less than one stop,
• wherein a setting increment for the setting value for the exposure control parameter in the setting unit can be set to at least one of ½-stop increments and ⅓-stop increments;
• and
• carrying out control for displaying the setting value for the exposure control parameter set in ½-stop increments or ⅓-stop increments without using the stop expression indicative of a stop that is less than one stop,
• wherein in a case where the setting value set when the setting increment is ½-stop increments or ⅓-stop increments is equal to the setting value set when the setting increment is 1/n-stop increments, the setting value is displayed without using the stop expression indicative of a stop that is less than one stop if the setting increment is ½-stop increments or ⅓-stop increments, and the setting value is displayed as a numerical value in one-stop increments and a fraction serving as a stop expression indicative of a stop that is less than one stop if the setting increment is 1/n-stop increments.

A non-transitory computer-readable storage medium which stores a program for causing a computer to execute a control method comprising:

• carrying out control so that the setting value for the exposure control parameter set in 1/n-stop increments is displayed as a numerical value in one-stop increments and a fraction serving as a stop expression indicative of a stop that is less than one stop,
• wherein a setting increment for the setting value for the exposure control parameter in the setting unit can be set to at least one of ½-stop increments and ⅓-stop increments;
• and
• carrying out control for displaying the setting value for the exposure control parameter set in ½-stop increments or ⅓-stop increments without using the stop expression indicative of a stop that is less than one stop,
• wherein in a case where the setting value set when the setting increment is ½-stop increments or ⅓-stop increments is equal to the setting value set when the setting increment is 1/n-stop increments, the setting value is displayed without using the stop expression indicative of a stop that is less than one stop if the setting increment is ½-stop increments or ⅓-stop increments, and the setting value is displayed as a numerical value in one-stop increments and a fraction serving as a stop expression indicative of a stop that is less than one stop if the setting increment is 1/n-stop increments.

An electronic device comprising a memory and at least one processor and/or at least one circuit to perform the operations of the following units:

• a setting unit configured to be able to set a setting value for at least one exposure control parameter among aperture, shutter speed, and ISO sensitivity in 1/n-stop increments (where n is an integer greater than or equal to 8);
• and
• a display control unit configured to carry out control so that the setting value for the exposure control parameter set in 1/n-stop increments is displayed as a numerical value in one-stop increments and a stop expression indicative of a stop that is less than one stop,
• wherein in a case where the stop less than one stop is m/n (where m is an integer greater than or equal to 1 and less than n), the display control unit carries out control so that m indicators are displayed as the stop expression,
• a setting increment for the setting value for the exposure control parameter in the setting unit can be set to at least one of ½-stop increments and ⅓-stop increments, and
• the display control unit carries out control for displaying the setting value for the exposure control parameter set in ½-stop increments or ⅓-stop increments without using the stop expression indicative of a stop that is less than one stop, and
• wherein in a case where the setting value set when the setting increment is ½-stop increments or ⅓-stop increments is equal to the setting value set when the setting increment is 1/n-stop increments, the setting value is displayed without using the stop expression indicative of a stop that is less than one stop if the setting increment is ½-stop increments or ⅓-stop increments, and the setting value is displayed as a numerical value in one-stop increments and a stop expression indicative of a stop that is less than one stop if the setting increment is 1/n-stop increments.
