Image capturing apparatus capable of performing omnifocal photographing, method of controlling same, and storage medium

A method of controlling an apparatus including an image capturing section configured to capture an image of an object, a lens configured to cause the image of the object to be formed on an image sensor, and an operation section configured to acquire photographing conditions including a focus movement amount and a number of images to be photographed from a user, the method comprising:

• controlling the lens and the photographing unit to sequentially acquire images to be photographed the number of which is the acquired number, by discretely displacing a focal length by the acquired focus movement amount;
• and
• calculating, whenever acquiring one of the acquired number of images to be photographed, a combining map indicative of a combining ratio of respective pixels at same positions in all of the acquired images, generating a combined image based on all of the acquired images according to the combining map, and sequentially displaying the generated combined images by superimposing information on the combining map thereon.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of controlling an apparatus including an image capturing section configured to capture an image of an object, a lens configured to cause the image of the object to be formed on an image sensor, and an operation section configured to acquire photographing conditions including a focus movement amount and a number of images to be photographed from a user, the method comprising:
