Image capturing apparatus capable of intermittently capturing images, method for controlling the same, and recording medium

A method for controlling an image capturing apparatus, the method for intermittently acquiring first images for use in generating a time lapse moving image, from among images corresponding to frames included in a moving image acquired using an image capturing unit of the image capturing apparatus, the method comprising:

• performing photometry of an object;
• based on a result of the photometry, setting a target value regarding an exposure when an image is acquired using the image capturing unit;
• calculating a control value with respect to each frame regarding the exposure when brightness is changed toward the set target value;
• and
• controlling the exposure based on the calculated control value,
• wherein in a predetermined period from predetermined timing before each first image is acquired to when the first image is acquired, the exposure is changed by a first degree of change, and outside the predetermined period, the exposure is changed by a second degree of change different from the first degree of change, and
• wherein in a case where the same amount of exposure is changed in the predetermined period and outside the predetermined period, the exposure changes more steeply by the first degree of change than by the second degree of change when an image is acquired.

A non-volatile recording medium having stored therein a program for causing a computer to execute a process for controlling an image capturing apparatus, the process for intermittently acquiring first images for use in generating a time lapse moving image, from among images corresponding to frames included in a moving image acquired using an image capturing unit of the image capturing apparatus, the method comprising:

• performing photometry of an object;
• based on a result of the photometry, setting a target value regarding an exposure when an image is acquired using the image capturing unit;
• calculating a control value with respect to each frame regarding the exposure when brightness is changed toward the set target value;
• and
• controlling the exposure based on the calculated control value,
• wherein in a predetermined period from predetermined timing before each first image is acquired to when the first image is acquired, the exposure is changed by a first degree of change, and outside the predetermined period, the exposure is changed by a second degree of change different from the first degree of change, and
• wherein in a case where the same amount of exposure is changed in the predetermined period and outside the predetermined period, the exposure changes more steeply by the first degree of change than by the second degree of change when an image is acquired.
