Abstract

An image capturing apparatus receives shake information detected by, for example, a sensor which detects a shake, and determines whether the hold status of the image capturing apparatus is handheld or fixed, based on the shake information (first shake determination). Also, the image capturing apparatus sequentially acquires images output upon photoelectric conversion by charge-accumulation type photoelectric conversion elements, and determines whether the hold status is handheld or fixed, based on an image displacement between the images (second shake determination). The exposure settings at the time of image capturing are changed between the case wherein it is determined by first shake determination that the hold status is fixed, and that wherein it is determined by second shake determination that the hold status is fixed.

First claim

What is claimed is:

1. An image capturing apparatus comprising:
a first shake determination unit configured to receive shake information detected by a shake detection unit, and determine whether a shake amount of the image capturing apparatus is smaller than a first predetermined amount, based on the shake information;
a second shake determination unit configured to determine whether the shake amount of the image capturing apparatus is smaller than a second predetermined amount,…
