Description of the Invention: [Technical Field] The present invention relates to a vision inspection apparatus, and more particularly to an eye examination apparatus capable of simultaneously detecting a black and white visual acuity value and a color visual acuity value of a subject. [Prior Art] Referring to Figures 1 to 2, most of the common visual inspection methods today include a plurality of gaps with Landolt-Cs or a number of uppercase English letters E. The visual acuity checklist is used to detect the visual acuity of the subject' because the visual acuity checklist is mostly presented in black on a white background, so the visual acuity value may also be referred to as the black and white visual acuity value of the subject. In addition, the subject's color recognition ability for different colors (hereinafter referred to as color vision 'value) is commonly used in the current state of color card or color blind identification map to determine whether the subject is color blind. defect. However, in general, human vision is sensed by two kinds of cells: one is the rod-shaped cells used to identify the brightness, and the other is the cone-shaped cells used to identify the color. In today's medical research, the so-called The color blindness can be further subdivided into yellow-blue blind and red-green blindness, that is to say, patients with yellow-blue blind symptoms cannot clearly distinguish between yellow and blue, but for other colors (such as red and green) It can be clearly distinguished that the same reason 'patients with red-green blindness' can still distinguish clearly from colors other than red and green. The reason for this is because patients with color-blindness in specific colors have damaged yellow-blue cones in the cones to identify yellow and blue (this is yellow-blue blind) or 3 to identify red and green. 201032772 The result of damage to red-green cone cells (this is red-green blindness). However, the method of using the color card or the color blind identification map can only detect whether there is a visual defect of color blindness or color weakness, because it does not let the subject judge whether the size of the target object will affect the subject to see clearly, so It is impossible to effectively detect the ability of the human eye to recognize colored objects. That is to say, although the traditional eye chart can check the eyesight of the human eye, because the target is black and white, the detected vision is the gray scale of the rod cells or cone cells (no chroma) The ability to recognize is not good, but it is impossible to detect the eyesight value of the human eye on the colored target. Therefore, today's tools for vision detection, whether it is an eye chart or a color-blind identification card, cannot effectively detect the color vision value of the human eye. However, the color vision value of the human eye is becoming more and more important in today's life. For example, in certain industries, the practitioner often needs to have more precise color recognition capabilities, such as: art workers, physicians, and the like. Assume that in the case of a physician's interpretation of certain specific conditions (eg, cancer), normal cell smears and abnormal cell smears are only slightly different in color (eg, pink and deep red). Therefore, if the doctor's own identification of a specific color (for example, red) is weak, it may often lead to misjudgment and thus affect the subsequent treatment results of the patient. Therefore, how to directly and effectively detect the black and white vision of the subject simultaneously Value and color vision values are one of the directions that are worthy of research and improvement. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a visual acuity inspection device for detecting a visual acuity value of a subject, which comprises: 4 201032772 a storage device for storing a detection pattern, the detection pattern comprising a a background area having a first color and a foreground area having a second color; a display 'to display the detection pattern; - a processor to change the first color and the second color, and setting the first -, The second color is a different color, and according to the degree of recognition of the subject before the detection pattern, the size of the foreground area of the detection pattern displayed by the display is changed to obtain the most

[Embodiment] The foregoing and other technical contents, features, and effects of the present invention are described below with reference to three preferred embodiments of the drawings. In the detailed description, it will be clearly presented. The first preferred embodiment of the present invention includes: a memory 31 for storing a detection pattern, a display 32' for displaying the detection pattern, and a A processor 33 for changing the color and size of the detection pattern 1. Referring to FIG. 3, the detection pattern 1 includes a background area 11 having a first color and a foreground area 12 having a second color, and the processor 33 sets the first and second colors to be different colors, for example The color of the background area 11 of the detection pattern 1 is red, and the color of the foreground area 12 of the detection pattern 1 is green. In this embodiment, the detection pattern 1 may be a color blue Dole® or a color uppercase English letter E, or a two-color parallel line segment. In the present embodiment, the first color and the second color of the detection pattern 1 are mainly composed of six color gradations of red, green, yellow, blue, black, and white, in order to detect the subject. Black and white vision and color vision (including: 201032772, · ', color vision value and yellow / blue visual value), so can be combined with the following six different color combinations: (1) Do not have 12 red, background area 11 (2) The fresh scenic area 12 is green, the background area u is red; (3) m scenic area 12 is yellow, and the background area 11 is blue; (4) the other scenic area 12 is blue, and the background area is yellow; (5) The fresh view area 12 is black, the background area 11 is white; and (6) the scenic area 12 is white, and the background area u is black. ® H's idea is that 'the above color set is not limited to the listed color system'. The color color in the color set can be increased or decreased according to different needs (for example, adding purple color), and each The color combination can also be changed according to the actual situation, and is not limited to the above six color combinations. For example, & detects whether the sensor has symptoms of yellow-green blindness, the processor can set the other scenic area 12 to be yellow, and the background area u is set to green for detecting yellow-green vision. In addition to setting the color of the detection pattern, the y 4 processor 33 also changes the size of the foreground area according to the degree of recognition of the other scenes to determine the visual value of the test subject, and the subject is for some kind of The visual value of the color combination refers to the minimum viewable angle (MSVA) of the subject. The so-called minimum resolvable viewing angle is the visual resolution of the interpretation space graphic or the spadai resolution. Referring to Figure 5, the minimum resolvable viewing angle is detected by the human eye for a distance d. The pattern (such as: a Randol circle), the smallest identifiable 201032772 opening south degree h, with the -yf field female broadcast, the smallest visible visual value /, the normal person with standard vision The limit of the angle of view is about 诤诤 ,, ^ horse 1 radians (min· of arc), the calculation is as follows: Vision value = one ~ ί_ msva Change the money, the visual value in the traditional visual inspection The subject has a minimum distinguishable viewing angle of Q5 radians, so that an object smaller or farther away than a standard (visual value of 1.G) can be seen. In view of the above description, in this embodiment, The size of the detection pattern i is selected from a certain number of levels in a specific range, for example: from 10 to 0.5 radians into 2 levels, the worst visual value is 〇" and the optimal visual value is 2.0, and each The visual value corresponding to the level is different. Therefore, when the visual acuity inspection device of the embodiment is used to test the subject, the processor 33 first takes out the pre-stored detection pattern 1 from the storage 31, and then according to the foregoing six A set of different color combinations is selected as the color of the scenic area 12 and the background area U before the detection pattern 1. Then, the processor 33 selects one of the 20 size levels to set the size of the detection pattern 1, and borrows The processed detection pattern i is transmitted by the processor 33 to the display 32 and displayed on the display 32, and then the corresponding minimum distinguishable height is obtained according to the minimum opening height h of the detection pattern 1 that the subject can recognize. The angle of view and then the visual value of the subject for the selected color group is calculated. 201032772 Referring to FIG. 6, in detail, the flow of using the visual acuity inspection device of the present invention to detect the visual value of the subject includes the following steps: Step 901: The processor 33 selects one of the preset color combinations as the detection one. Step 902 is that the processor 33 selects one of the preset size levels to set the size value of the detection pattern 1; Step 903: the display 32 displays the detection pattern i to For the testee

To continue the detection, all the detection actions are ended; & return to step 901, if no, step 908 is that the processor 33 selects the size of the foreground area 12 to be updated by the larger size and the size is updated to the newly selected size. Then jump back to step 9 201032772 903 °. Next, the processor 33 changes the first color and the second color of the detection pattern t to repeat the previous color combination to perform another color combination on the subject. The visual acuity test, and so on, can be used to know the black and white visual acuity value of the subject and the color visual acuity value including the red and green visual acuity value and the yellow and blue visual acuity value. It is worth noting that among the above six different color groups, the first and second groups are the background area 11 and the foreground area! 2 exchange color, the purpose is to test the subject's red and green visual acuity 'but the results of the first group and the second group can be slightly different, this difference is caused by the halo phenomenon but not Significantly affects the visual acuity of the test. Therefore, if considering the simplified cost, one of the groups can be retained as the red and green visual acuity value of the test subject. Similarly, the third, fourth and fifth and sixth groups are also Only one of the groups can be reserved to detect the yellow-blue visual value and the black-and-white visual value. The second preferred embodiment is that the second preferred embodiment of the visual acuity inspection apparatus of the present invention is most different from the first preferred embodiment in that the storage 31 stores a plurality of sets of detection patterns and belongs to the same group. The detection pattern will have a background area u of the same color and a depression area 12, but the size of the foreground area 12 is different from each other. The background area U of the detection patterns belonging to different groups and the color of the foreground area 12 are not exactly the same. For example, in the first set of detection patterns, the background area of all the detection patterns i is green, and the size of the foreground area 12 is different but both are red; and in the second group of detection patterns, the background area of all the detection patterns 11 is yellow, and the size of the foreground area 12 is different from each other but is blue; while in the third group of detection 10 201032772, the background area 11 of all the detection patterns is white, and the size of the foreground area 12 is mutually Not the same but all black. Therefore, when the subject is to detect the red-green visual value of the subject, the processor 33 selects the first set of detection patterns to test the subject', and when the subject's yellow-blue visual value is to be detected, the second set of detection patterns is selected. To detect black and white visual acuity, select the third set of detection patterns. It is worth noting that the set of test patterns stored in the memory 3 is not limited to these, the color can be increased or changed depending on the use case, or even a set of test patterns can be stored. _
