  The binocular noise information storage unit 102 stores binocular noise information that is information of binocular noise in which the information for the right eye and the information for the left eye are different. The binocular noise information includes information for the right eye and information for the left eye. However, both information may overlap or may exist in different areas. In addition, for example, the binocular noise information is the same for the right eye design and the left eye design except for the target, and the information of the binocular retinal images with different information is different because the positions of both symbols are shifted. This is noise information. Here, the target is a portion of the three-dimensional pattern to be inspected, and is a portion of an answer that the inspector wants to hit. The symbol includes a pattern, a character, a figure, and the like. In addition, for example, the binocular noise information is information on non-interocular noise that is binocular noise in which the information for the right eye and the information for the left eye are different because the design for the right eye is different from the design for the left eye It is. It is preferable that the binocular noise information includes target candidates that are a plurality of target candidates. An example of binocular noise information will be described later. The design of the binocular noise information does not matter. The binocular noise information storage unit 102 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium.

  The binocular noise information acquisition unit 103 acquires the binocular noise information in the binocular noise information storage unit 102. The binocular noise information acquisition unit 103 normally acquires binocular noise information when the instruction receiving unit 101 receives an instruction to output binocular noise information, but automatically or by other triggers. Binocular noise information may be acquired.

The determination result output unit 107 may be considered as including or not including an output device such as a display or a speaker. The determination result output unit 107 may be realized by output device driver software or output device driver software and an output device.

Next, the operation of the stereoscopic inspection apparatus will be described using the flowchart of FIG.
(Step S201) The instruction receiving unit 101 determines whether an instruction to output binocular noise information has been received. If an output instruction is accepted, the process goes to step S202, and if no output instruction is accepted, the process returns to step S201.
(Step S202) The binocular noise information acquisition unit 103 acquires the binocular noise information from the binocular noise information storage unit 102.
(Step S203) The binocular noise information output unit 104 outputs the binocular noise information acquired in step S202.
(Step S204) The correctness / incorrectness determination unit 106 substitutes 1 for a counter i.

(Step S205) The correctness determination unit 106 determines whether or not “i <= n”. If “i <= n”, the process proceeds to step S206. If “i <= n”, the process ends. Note that n is the number of answers to be input. That is, for example, n is the number of examiners.
(Step S206) The correctness determination unit 106 determines whether or not the i-th answer has been received. If the i-th answer is accepted, the process proceeds to step S207. If the i-th answer is not accepted, the process returns to step S206.

(Step S207) The correct / incorrect determination unit 106 acquires correct answer information stored in advance. In addition, it is preferable that the correct answer information stored in advance is not one but exists corresponding to the output binocular noise information.
(Step S208) The correctness / incorrectness determination unit 106 determines whether the answer is correct based on the answer received in step S206 and the correct answer information acquired in step S207.
(Step S209) The determination result output unit 107 outputs the correct / incorrect determination result in step S208.

That is, the determination result output unit 107 may output one of “OK / NG” depending on whether or not the answers of all the inspectors are correct. The determination result output unit 107 may output the number of correct answers. In addition, the output form of the determination result in the determination result output unit 107 does not matter.
Hereinafter, a specific operation of the stereoscopic inspection apparatus according to the present embodiment will be described.

  First, it is assumed that the binocular noise information storage unit 102 stores the binocular noise information shown in FIG. This binocular noise information is information of binocular retinal image difference noise. 3A shows information for the right eye, and FIG. 3B shows information for the left eye. Then, the examiner gives an instruction to output binocular noise information using, for example, a remote controller. Next, the binocular noise information acquisition unit 103 acquires the binocular noise information of FIG. The binocular noise information output unit 104 outputs the binocular noise information of FIG. An output example of such binocular noise information is shown in FIG. In FIG. 4, codes “1” to “6” are codes assigned to the target candidates. It is assumed that the inspector has been educated to input a code corresponding to the target with the remote controller when the target is detected in advance. Note that the target is a bar that is three-dimensionally different from the other of the six bars on the screen of FIG. In the example of FIG. 4, it is assumed that the numbers “1”, “2”, “3”, “4”, “5”, and “6” are assigned clockwise from the upper right bar among the six bars. The person presses the number corresponding to the target with the remote controller.

Next, the inspector inspects the target and inputs the number with the remote controller. Here, it is assumed that the inspector presses the button “6” on the remote controller.
The correctness determination unit 106 accepts the answer “6”. Further, the correctness determination unit 106 stores that the correct answer corresponding to the binocular noise information in FIG. 3 is “6”.
Then, the correct / incorrect determination unit 106 determines that the answer is “correct” based on the received answer “6” and the correct answer “6”.

Next, the determination result output unit 107 outputs a correct / incorrect determination result “correct answer”. When the correct / incorrect determination result is “incorrect”, the correct / incorrect determination unit 106 may be configured to output a beep sound to an external speaker, or from the production line (stereoscopic television inspection line) The configuration may be such that a signal for removing the stereoscopic television is output to a control device (not shown) of the production line.
The output of the correct / incorrect determination result “correct answer” indicates that the examiner can easily see the stereoscopic pattern of the stereoscopic inspection apparatus based on the information of the binocular retinal image difference noise.

Next, it is assumed that the binocular noise information storage unit 102 stores the binocular noise information shown in FIG. The binocular noise information is information regarding noise that is not compatible with the binocular. 5A shows information for the right eye, and FIG. 5B shows information for the left eye. Then, the examiner gives an instruction to output binocular noise information using the remote controller. Next, the binocular noise information acquisition unit 103 acquires the binocular noise information of FIG. The binocular noise information output unit 104 outputs the binocular noise information of FIG. An output example of such binocular noise information is shown in FIG. In FIG. 6, the symbols “1” to “6” are the symbols assigned to the target candidates.
Next, the inspector inspects the target and inputs the number with the remote controller. Here, it is assumed that the inspector presses the button “4” on the remote controller.
The correctness determination unit 106 accepts the answer “4”. Further, it is assumed that the correctness determination unit 106 stores that the correct answer corresponding to the binocular noise information in FIG. 5 is “4”.
Then, the correctness determination unit 106 determines that the answer is “correct” based on the accepted answer “4” and the correct answer “4”.
Next, the determination result output unit 107 outputs a correct / incorrect determination result “correct answer”.
The output of the correct / incorrect determination result “correct answer” indicates that the inspector can easily see the stereoscopic pattern of the stereoscopic inspection apparatus even based on the information on the noise that does not correspond to both eyes.

As described above, according to the present embodiment, it is possible to inspect whether or not a stereoscopic pattern is easy to see by a stereoscopic inspection apparatus that outputs binocular noise information.
