Image capturing apparatus capable of displaying live view image high in visibility, method of controlling image capturing apparatus, and storage medium

A method of controlling an image capturing apparatus including a recording unit, a display unit, an image capturing unit configured to convert light from an object to image signals, an image processing unit configured to perform image processing on image data formed by the image signals obtained by the image capturing unit, and a reception unit configured to receive an instruction for setting a live view mode which is an operation mode for realizing a live view function for displaying image data subjected to the image processing on the display unit without recording the image data in the recording unit, comprising:

• causing, in a case where a second live view mode is set which is different from a first live view mode for displaying image data subjected to the image processing on the display unit based on photographing settings set by a user,
• the image capturing unit to perform photographing under an exposure condition in the second live view mode, which is set to an exposure condition darker than a determined proper exposure,
• the image processing unit to perform gradation conversion for compensating for a difference in exposure condition from the proper exposure, and
• the display unit to control display luminance in the second live view mode to be brighter than display luminance in the first live view mode.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of controlling an image capturing apparatus including a recording unit, a display unit, an image capturing unit configured to convert light from an object to image signals, an image processing unit configured to perform image processing on image data formed by the image signals obtained by the image capturing unit, and a reception unit configured to receive an instruction for setting a live view mode which is an operation mode for realizing a live view function for displaying image data subjected to the image processing on the display unit without recording the image data in the recording unit,

• wherein the method comprises:
• causing, in a case where a second live view mode is set which is different from a first live view mode for displaying image data subjected to the image processing on the display unit based on photographing settings set by a user,
• the image capturing unit to perform photographing under an exposure condition in the second live view mode, which is set to an exposure condition darker than a determined proper exposure,
