Abstract

In an image taking apparatus having a mechanism for freely inserting/removing an IR cut filter on an optical axis of an image taking optical system of the image taking apparatus, the IR cut filter is made of one of film material and sheet material. Further the mechanism changes an image taking mode of the image taking apparatus between a first mode where the IR cut filter is located on the optical axis of the image taking optical system and a second mode, that is a low level light image taking mode where the IR cut filter is removed from the optical axis of the image taking optical system.

Claims

1. An image taking apparatus comprising:

a mechanism for inserting/removing a filter on/from an optical axis of an image taking optical system of the image taking apparatus, wherein;

said filter is made of one of film material and sheet material.

2. The image taking apparatus as cited in claim 1, wherein;

said filter is an IR cut filter; and

said mechanism changes an image taking mode of the image taking apparatus between a first mode where the IR cut filter is inserted on the optical axis of the image taking optical system and a second mode where the IR cut filter is removed from the optical axis of the image taking optical system.

3. The image taking apparatus as cited in claim 2, wherein;

said mechanism for changing the image taking mode between the first mode and the second mode directly drives the IR cut filter.

4. The image taking apparatus as cited in claim 2, wherein;

said IR cut filter is formed by applying an IR cut coating on said one of film material and sheet material.

5. The image taking apparatus as cited in claim 1, wherein;

said image taking optical system has an inner focus type configuration.
