Abstract:
1. An image taking apparatus comprising: an image pickup element which photoelectrically converts an object image formed by an image-taking lens to an electrical signal; a focus detection unit configured and positioned to detect a focusing state of the image-taking lens according to a phase difference detection system by using a light flux directed from the image-taking lens; a half mirror which reflects a part of the light flux from the image-taking lens and through which the other part of the light flux passes; and a display section which displays image data obtained using the image pickup element, wherein the half mirror changes its state between a first state and a second state, wherein in the first state, the light flux reflected by the half mirror is directed to the focus detection unit and the light flux passing through the half mirror is directed to the image pickup element, and wherein in the second state, the light flux from the image-taking lens is directed only to the image pickup element by withdrawing the half mirror from an image-taking optical path, and wherein, when the half mirror is in the first state, the display section is controlled so as not to display an image-taking area of the image pickup element which is obtained in the first state and not obtained in the second state.
