Abstract

A visual aid display apparatus 1 includes, an image capturing section 50 for image capturing of a subject; an image processing section 60 for processing the image, information obtained from the image capturing section 50 so that the image information can be displayed, a display device for displaying the video of image information having been subjected to processing, an ocular optical system for providing video by leading to the eye the light coming from the display device, and a control section 70 for providing control in such a way that the video of the image information having been subjected to image processing can be displayed on the display area of the display section 10. The video of the external world and the image-processed image of the display area A can be viewed simultaneously by an observer on the display section 10.

Claims

1. A visual aid display apparatus comprising:

an image capturing section for capturing a subject;

an image processing section for performing processing so as to display the image data obtained from the image capturing section;

a display section further comprising;

a display device for displaying the video of the image data processed by the image processing section, and

an ocular optical system for providing video by leading the light from of the display device to the eyes; and

a control section for providing control in such a way that the video of the processed image can be displayed in display area of the display section;

wherein the video of the external world and processed image in the display area are visible concurrently on the display section.

2. The visual aid display apparatus of claim 1, wherein the size of the display area setting the size in the vertical direction is greater than that in the lateral direction.

3. The visual aid display apparatus of claim 1, wherein an installation site of the display area can be changed.

4. The visual aid display apparatus of claim 1, wherein the transmittance in the display area does not exceed 40 percent that in the area surrounding the display area.

5. The visual aid display apparatus of claim 1, wherein the control section is the information required for display is extracted from the image capturing visual field of the capturing section, and the size of the display area is changed, based on the image data.

6. The visual aid display apparatus of claim 1, wherein the control section extracts the information required for display, from the image capturing visual field of the capturing section, and moves the display area, based on the visual field information.

7. The visual aid display apparatus of claim 1, wherein the control section allows an enlarged view to be displayed according to the image characteristic information obtained from the image capturing section.

8. The visual aid display apparatus of claim 1, wherein the image processing section perform image processing, including enlargement/reduction processing, frequency correction, color tone correction, luminance compression and image extraction.

9. The visual aid display apparatus of claim 1, further comprising:

a warning section for detecting approach to the subject and issuing a warning.

10. The visual aid display apparatus of claim 1, further comprising:

a luminance processing section for processing the brightness on the display section does not exceed 1,000 cd/m².

11. The visual aid display apparatus of claim 1, wherein the chroma of the inputted image data is increased to display an image on the display section.

12. The visual aid display apparatus of claim 1, wherein the profile of the inputted image data is enhanced to display an image on the display section.

13. The visual aid display apparatus of claim 1, wherein the brightness displayed on the display section is controlled in conformity to a photometer section and the brightness measured by the photometer section.
