Abstract

An imaging device comprises a photographing lens, a first imaging sensor for taking a subject image formed by the photographing lens, a second image sensor for taking a subject image formed by the photographing lens, an optical path switching section for selectively switching subject light that has passed through the photographing lens to either one of the first image sensor or the second image sensor, a display section for displaying an image taken by the second image sensor, and a display region storage section for storing information representing a region for display on the display section from a region where imaging by the second image sensor is possible. The display section controls the display region based on the information stored in the display region storage section.

Claims

1. An imaging device, comprising:

a photographing lens;

a first imaging sensor for taking a subject image formed by the photographing lens;

a second imaging sensor for taking a subject image formed by the photographing lens;

an optical path switching section for selectively switching subject light that has passed through the photographing lens to either one of the first image sensor or the second image sensor;

a display section for displaying an image taken by the second image sensor; and

a display region storage section for storing information representing a region for display on the display section from a region where imaging by the second image sensor is possible, wherein

the display section controls the display region based on the information stored in the display region storage section.

2. The imaging device of claim 1, further comprising a screen for forming a subject image that has passed through the photographing lens, wherein the second image sensor takes the subject image that has been formed on the screen.

3. The imaging device of claim 2, further comprising an imaging lens for guiding a subject image displayed on the screen to a photographer'"'"'s eye.

4. The imaging device of claim 2, wherein the screen has a rectangular display section, information of a specified rectangular display region, having intersect points of two diagonal lines of a rectangular display section of the screen as a center, is stored in the display region information storage section, and a position of an image formed on the screen and a position of an image formed using the first image sensor are subjected to predetermined adjustment.

5. An imaging device, comprising:

a first image sensor for forming an image of a subject image formed using an imaging lens for storage;

a subject viewing optical system for optically displaying a subject image based on subject light flux;

a second image sensor arranged within the subject viewing optical system;

a display section for displaying a subject image based on output of the first image sensor and the second image sensor; and

a display region storage section for storing adjustment values for adjustment of image display regions based on output of the first image sensor and the second image sensor so that a display region based on output of the first image sensor and a display region based on output of the second image sensor match, wherein

the display section controls the display region based on the adjustment values stored in the display region storage section.

6. The imaging device of claim 5, wherein the adjustment values are determined such that a display center of an image based on output of the first image sensor on the display device matches a display center of an image based on output of the second image sensor.

7. The imaging device of claim 5, wherein the display region storage section stores clipping start position information for a display region for displaying based on output of the first and second image sensors, display region horizontal width information, and display region vertical width information as the adjustment values.

8. The imaging device of claim 5, wherein the display region storage section stores position information corresponding to three points inside four corners of a display region for displaying based on output of the first and second image sensors, display region horizontal width information, and display region vertical width information, as the adjustment values.
