Abstract

Embodiments of the present disclosure relate to a field of vision testing technique, and particularly to a vision testing apparatus and method. The vision testing method and apparatus can concurrently test vision and ability for distinguishing colors concurrently by using vision synthetic-testing pictures, wherein a character in the vision synthetic-testing picture is used to test the vision, and color combination in the vision synthetic-testing picture is used to test the ability for distinguishing colors.

First claim

What is claimed is:

1 . A vision testing apparatus comprising:
a display unit configured to display a vision synthetic-testing picture; a controller configured to receive a vision testing feedback of a tested subject to the vision synthetic-testing picture and transmit the vision testing feedback to a processing unit; the processing unit configured to generate a vision judgment result based on the vision testing feedback, wherein a character in the vision synthetic-testing picture is used to test the vision, and color combination in the vision synthetic-testing picture is used to test the ability for distinguishing colors.

2 . The vision testing apparatus of claim 1 , wherein the vision judgment result is a vision testing result or information indicating a next vision synthetic-testing picture to be displayed, wherein the information indicating the next vision synthetic-testing picture to be displayed comprises picture information and color combination information of the next vision synthetic-testing picture to be displayed.

3 . The vision testing apparatus of claim 2 , further comprising:
a picture calling unit configured to receive the picture information of the next vision synthetic-testing picture to be displayed, call vision testing picture information corresponding to the picture information of the next vision synthetic-testing picture to be displayed, and transmit the vision testing picture information to the display unit, the picture information comprising information of characters in the vision synthetic-testing picture; and a color calling unit configured to receive the color combination information of the next vision synthetic-testing picture to be displayed, call the vision testing color combination corresponding to the color combination information of the next vision synthetic-testing picture to be displayed, and transmit the vision testing color combination to the display unit, wherein the display unit displays the next vision synthetic-testing picture to be displayed according to the vision testing picture and the vision testing color combination.

4 . The vision testing apparatus of claim 2 , wherein the controller is a handle controller arranged with buttons or joystick used to input vision testing feedback.

5 . The vision testing apparatus of claim 1 , wherein the color combination of the vision synthetic-testing picture is any one of red and green combination, purple and brown combination, red and brown combination, and red, green, grey and purple combination.

6 . A vision testing method comprising concurrently testing vision and ability for distinguishing colors by using vision synthetic-testing pictures, wherein a character in the vision synthetic-testing picture is used to test the vision, and color combination in the vision synthetic-testing picture is used to test the ability for distinguishing colors.

7 . The vision testing method of claim 6 , wherein said concurrently testing vision and ability for distinguishing colors by using vision synthetic-testing pictures comprises:
displaying a vision synthetic-testing picture; receiving a vision testing feedback of a tested subject to the displayed vision synthetic-testing picture; and generating a vision judgment result based on the vision testing feedback.

8 . The vision testing method of claim 7 , wherein the vision judgment result is a vision testing result or information indicating a next vision synthetic-testing picture to be displayed, wherein the information indicating the next vision synthetic-testing picture to be displayed comprises picture information and color combination information of the next vision synthetic-testing picture to be displayed.

9 . The vision testing method of claim 8 , wherein said concurrently testing vision and ability for distinguishing colors by using vision synthetic-testing pictures further comprises:
receiving the picture information and the color combination information of the next vision synthetic-testing picture to be displayed, the picture information comprising information of characters in the vision synthetic-testing picture; calling the vision testing picture information corresponding to the picture information of the next vision synthetic-testing picture to be displayed; and calling the vision testing color combination information corresponding to the color combination information of the next vision synthetic-testing picture to be displayed, wherein the next vision synthetic-testing picture to be displayed and the displayed vision synthetic-testing picture have a same vision level or different vision levels.

10 . The vision testing method of claim 9 , further comprising:
displaying the next vision synthetic-testing picture according to the vision testing picture information and the vision testing color combination information; receiving a vision testing feedback of the tested subject to the displayed next vision synthetic-testing picture; generating another vision judgment result based on the vision testing feedback.

11 . The vision testing method of claim 7 , wherein the color combination of the vision synthetic-testing picture is any one of red and green combination, purple and brown combination, red and brown combination, and red, green, grey and purple combination.

12 . The vision testing method of claim 9 , wherein in case that the vision detecting feedback coincides with the displayed vision synthetic-testing picture, the vision judgment result is information of a vision synthetic-testing picture having a vision level being one-level higher than that of the displayed vision synthetic-testing picture.

13 . The vision testing method of claim 12 , wherein in case that the vision detecting feedback coincides with the displayed vision synthetic-testing picture for two or three times continuously, the vision judgment result is information of a vision synthetic-testing picture having a highest vision level in a vision testing table.

14 . The vision testing method of claim 9 , wherein in case that the vision detecting feedback does not coincide with the displayed vision synthetic-testing picture, the vision judgment result is information of a vision synthetic-testing picture having a vision level being one-level lower than that of the displayed vision synthetic-testing picture.

15 . The vision testing method of claim 14 , wherein in case that the vision detecting feedback does not coincide with the displayed vision synthetic-testing picture for two or three times continuously, the vision judgment result is information of a vision synthetic-testing picture having a lowest vision level in a vision testing table.

16 . The vision testing method of claim 9 , wherein in case that the displayed vision synthetic-detecting picture has a color combination different from the black and write combination and the vision detecting feedback does not coincide with the displayed vision synthetic-testing picture, the next vision synthetic-detecting picture to be displayed has a same vision level in the vision detecting table as that of the displayed vision synthetic-detecting picture and has the black and write combination.

17 . The vision testing method of claim 9 , wherein in case that the displayed vision synthetic-testing picture has a black and write combination and the vision detecting feedback does not coincide with the displayed vision synthetic-testing picture, the next vision synthetic-detecting picture to be displayed has a vision level being one-level lower than that of the displayed vision synthetic-testing picture and has the bla
