Abstract

An anti-glare display system is provided, including: at least one camera unit disposed on a moving device, at least disposed on a rear side of the moving device, and photographing a major image in a direction opposite to a moving direction; a processing unit electrically connected to the at least one camera unit to receive the major image and dividing the major image to obtain at least one sub-image; at least one display unit comprising an electrochromic element and electrically connected to the processing unit to receive and display the sub-image from the processing unit; and a microcontroller electrically connected to the processing unit and the at least one display unit.

First claim

What is claimed is:

1. An anti-glare display system, comprising:
at least one camera unit disposed on a moving device, at least disposed on a rear side of the moving device, and photographing a major image in a direction opposite to a moving direction;
a processing unit electrically connected to the at least one camera unit to receive the major image and dividing the major image to obtain at least one sub-image;
at least one display unit comprising an electrochromic element and electrically connected to the processing unit to receive and display the sub-image from the processing unit; and
a microcontroller electrically connected to the processing unit and the at least one display unit;
wherein when the processing unit determines that a glare value of the sub-image is larger than a threshold value, the processing unit controls the microcontroller to adjust the electrochromic element of the display unit displaying the sub-image with the glare value being greater than the threshold value so as to adjust a degree of discoloration of the electrochromic element
wherein the camera unit comprises:
an optical image sensor receiving a light from the rear side of the moving device; and
a lens assembly positioned in front of the optical image sensor, and an optical axis of the lens assembly overlapping a central normal line of a sensing surface of the optical image sensor in such a way that the light focuses on the optical image sensor;
wherein the lens assembly comprises five, six, seven, eight, nine, or ten lenses having refractive power, and each of the lenses is arranged sequentially from an object side to an image side; the lens assembly satisfies the following condition:
0.1≤InTL/HOS≤0.95;

wherein, HOS is a distance from an object side surface of a lens farthest from an image plane to a sensing surface of the optical image sensor on an optical axis; InTL is a distance from an object side surface of a lens furthest from the image plane to a lens closest to the image plane on an optical axis.

2. The anti-glare display system according to claim 1 , wherein the processing unit determines ambient light intensity by the major image and determines glare light source intensity by the sub-image, and the glare value is a ratio of the glare light source intensity and the ambient light intensity.

3. The anti-glare display system according to claim 1 , wherein the display unit further comprises:
a transflective layer disposed between a transparent substrate of the electrochromic element and a transparent conductive layer to be used as a transflective mirror.

4. The anti-glare display system according to claim 3 , wherein the transflective layer has a transmittance between 1% and 99%.

5. The anti-glare display system according to claim 3 , wherein the transflective layer has a reflectance between 1% and 99%.

6. The anti-glare display system according to claim 3 , wherein the display unit further comprises:
a planar display device disposed in front of the transflective mirror along the moving direction and displaying the sub-image;
wherein the transflective mirror closely attaches the planar display device.

7. The anti-glare display system according to claim 1 , wherein the camera unit has a horizontal field of view at least larger than 45 degrees.

8. The anti-glare display system according to claim 1 , wherein the camera unit has a horizontal field of view between 45 degrees and 230 degrees.

9. The anti-glare display system according to claim 1 , wherein the processing unit calibrates the glare value with a calibration value, and the calibration value corresponds to a physiological reference value of a user of the moving device.

10. An image-capturing system, comprising the anti-glare display system according to claim 1 , wherein the image-capturing system is applied to an electronic portable device, an electronic wearable device, an electronic monitoring device, an electronic information device, an electronic communication device, a machine vision device, or a vehicle electronic device.
