Description

The present invention relates to an inspection system and a program, and more particularly, to an inspection system and a program capable of quantitatively performing an eye inspection.

  Ophthalmic examinations performed in ophthalmology include eye position examination and double image examination (for example, see Non-Patent Document 1).

  The eye position test is a test for checking whether the positions of the left and right eyes are normal. In the eye position examination, a point light source such as a penlight is placed in front of the subject, and the fixation is performed on the point light source. .

  The double image test is a test for checking whether or not the movement of the eyeball by the extraocular muscles of the eye is normal. In multiple image inspection, the subject's head is fixed to a chin rest, and, for example, as shown in FIG. 1, a red radial square is projected on a white screen in front of the subject, and the subject is examined. Place red glass 11 and green glass 12 in front of each eye. The subject looks at the grid through the red glass 11 and the green glass 12. Each square has a scale of 5 degrees, and the center of the front and the intersection of vertical and horizontal squares 15 to 30 degrees apart from the center of the front are indicated by circles. The subject holds the indicator that can project a green arrow with his right hand, and moves the indicator so that the tip of the arrow sequentially matches the circle at the intersection. The examiner writes the position indicated by the arrow with the arrow on the printing paper on which the squares are printed, and connects each measurement point with a line to generate the Hess chart 1 as shown in FIG. . Red and green have a complementary color relationship, and the green arrow is not visible only through the red square through the red lens 11, and the green lens 12 is reversed. When the user looks at the square with the eye placed in front of the red lens 11, he or she will fixate.

  In the Hess chart 1 of FIG. 1, when the white circle of the square is fixed with the right eye, the place seen by the left eye is indicated by a black circle, and the black circles corresponding to the white circles at every 15 degrees are connected by lines. Have been. In the Hess chart 1, the line of sight of the left eye when looking at 15 degrees to the right with the right eye protrudes from the chart, and the examiner determines that the right eye is abnormal. In this way, the examiner gives the result of the examination based on the Hess chart 1.

The position of the pointer is transmitted as the operation input data based on the operation input from the subject input in the operation.

  Next, an inspection process in the inspector inspection apparatus 31 of FIG. 4 will be described with reference to a flowchart of FIG. This processing is started when a command to start the examination is input to the operation input unit 151 by the examiner.

  In step S11, the display unit 156 displays an initial screen. Specifically, the main control unit 152 reads the data of the initial screen for the inspection from the file storage unit 157, and supplies this to the display control unit 155. The display control unit 155 controls the display unit 156 to display an image based on the data of the initial screen. The display unit 156 displays, for example, an initial screen as shown in FIG.

  FIG. 7 is a screen example of the initial screen. On the display unit 156, a button 301 indicating “multiple image examination”, a button 302 indicating “eye position examination”, a button 303 indicating “file search”, and an explanation “select a task to be executed” are displayed. And a button 304 indicating "end". Further, below the button 303, a comment 305 of double image inspection and eye position inspection is displayed. This comment 305 indicates that it is possible to perform a double image inspection and an eye position inspection file by file search. The examiner selects each of the buttons 301 to 304 by inputting a predetermined operation to the operation input unit 151. When the button 301 is selected, a multiple image test described later with reference to FIGS. 8 and 9 is performed. When the button 302 is selected, an eye position test described later with reference to FIGS. 19 and 20 is performed. When the button 303 is selected, a file search process in step S17 described later with reference to FIG. 6 is performed, and when the button 304 is selected, the process ends.

  Returning to FIG. 6, in step S12, the main control unit 152 determines whether or not to perform a double image inspection. Specifically, the main control unit 152 determines whether or not the multiple image inspection button 301 has been selected by the examiner (via the operation input unit 151) on the initial screen in FIG. When the multiple image inspection is performed, that is, when it is determined that the double image inspection button 301 is selected, the process proceeds to step S13, and the multiple image inspection unit 153 executes the multiple image inspection process. Details of this processing will be described later with reference to FIGS. If it is determined in step S12 that the double image inspection is not performed, that is, if it is determined that the eye position inspection button 302, the file search button 303, or the end button 304 has been selected on the initial screen of FIG. 7, the process proceeds to step S14. move on.

  In step S14, the main control unit 152 determines whether or not to perform an eye position test. Specifically, the main control unit 152 determines whether or not the eye examination button 302 has been selected by the examiner (via the operation input unit 151) on the initial screen in FIG. When the eye position test is performed, that is, when it is determined that the eye position test button 302 is selected, the process proceeds to step S15, and the eye position test unit 154 executes the eye position test process. Details of this processing will be described later with reference to FIGS. 19 and 20. If it is determined in step S14 that the eye position test is not performed, that is, if it is determined that the file search button 303 or the end button 304 has been selected on the initial screen in FIG. 7, the process proceeds to step S16.

  In step S16, the main control unit 152 determines whether to search for a file. Specifically, the main control unit 152 determines whether or not the file search button 303 has been selected by the examiner (via the operation input unit 151) on the initial screen in FIG. If it is determined that a file search is to be performed, that is, if it is determined that the file search button 303 has been selected, the process proceeds to step S17, and the file search unit 158 executes a file search process. Specifically, the display unit 156 displays a screen for inputting an examination name (multiple image examination or eye position examination) and a keyword (for example, subject name, subject ID, examination date and time) to be searched. The file search unit 158 searches for a file stored in the file storage unit 157 based on an input from the examiner to the operation input unit 151 with respect to. Thereby, the file of the inspection result can be searched and read.

  When it is determined in step S16 that the file is not to be searched, in step S18, the main control unit 152 determines whether to end the processing. Specifically, the main control unit 152 determines whether or not the end button 304 has been selected by the examiner (via the operation input unit 151) on the initial screen in FIG. If it is determined in step S18 that the process is not to be ended, after the process of step S13, after the process of step S15, or after the process of step S17, the process returns to step S11, and the subsequent processes are repeated. That is, the initial screen of FIG. 7 is displayed, and the process for the selected button is performed again.

  In step S18, if it is determined that the processing is to be ended, that is, if the end button 304 has been selected, the processing is ended.

  By the processing of FIG. 6, the multiple image inspection processing, the eye position inspection processing, and the file search processing are performed based on the request from the examiner.

  Next, the multiple image inspection processing in step S13 in FIG. 6 will be described with reference to the flowcharts in FIGS. The double image examination fixes the position of the subject's head, assigns one of red glass (lens) or green glass to the subject's left eye, and assigns the right eye's glass. Wear glasses with the other assigned before (lens color may be either left or right, for example, green glasses are assigned to the left eye and red glasses are assigned to the right eye) or cap-type glasses Then, a red square frame (hereinafter, also referred to as a target) is sequentially displayed at a predetermined position (for example, nine places) of the display unit 204 (of the subject inspection apparatus 32) in front of the subject, and the subject is examined. This is done by letting the user select the position where the red square frame can be seen so as to overlap (by operating the mouse 51) with the pointer of the green circle frame.

  In step S31, the operation input unit 151 receives an input of a parameter from the examiner. For example, the examiner inputs the subject ID of the subject, the name of the subject, the selection of the eye to be examined (right or left), and the like as parameters to the operation input unit 151. The parameters received by the operation input unit 151 are supplied to the parameter processing unit 171 of the multiple image inspection unit 153 via the main control unit 152.

  In step S32, the parameter processing unit 171 determines whether or not all the essential parameters have been input by the examiner. For example, since the check of input fields 352 and 353 (examiner ID and subject name) and an option button 360 on the examination side in FIG. 10 to be described later are essential parameters, the parameter processing unit 171 sets these essential parameters Is determined by the examiner. If it is determined that all the essential parameters have not been input, the process returns to step S31, and the subsequent processes are repeated.

  If it is determined in step S32 that all the essential parameters have been input, the process proceeds to step S33, and the display unit 156 performs the processing shown in FIG. 10 based on the image data transmitted through the multiple image inspection processing unit 172 of the multiple image inspection unit 153. The inspection screen as shown in is displayed. That is, the inspection is started.

  At the center of the display unit 156 in FIG. 10, a frame 350 for indicating the inspection result is displayed. In this case, R (right), L (left), U (upper), and D An axis indicating (bottom) and a numerical value indicating an angle are displayed. Also, at the top of FIG. 10, an examination date 351 displayed as January 21, 2004, an input field 352 for inputting a subject ID, a name field 353 for inputting a subject nomination, and confirmation and display Button 354 is displayed. Furthermore, on the left side of the display unit 156, an option button 360 displayed as a left eye and a right eye for selecting an eye to be tested, a button 370 displayed as a start of a test, a button 371 displayed as a return, a button 371 displayed as a return, and a display as a test interruption Button 372, a button 373 displayed as a result display, a button 374 displayed as a print, a button 375 displayed as a save, a button 376 displayed as an end, and a button 377 displayed as a condition setting are displayed. ing. The buttons 354, 370, 373 to 377 are items which cannot be selected by the examiner at present, and are displayed by broken lines. The buttons 371, 372 are items which can be currently selected by the examiner, and are displayed by solid lines ( Hereinafter the same). In addition, a pointer 380 operated and moved by the operation input unit 201 of the subject inspection apparatus 32 is displayed in a frame 350 in FIG.

  In step S31 described above, the examiner inputs the subject ID (aaa) in the input field 352, the subject's name (Ichiro Yamada) in the input field 353, and the right or left eye of the option button 360 on the examination side. In this case, since a parameter is input to the left eye), a display based on the parameter is made in FIG.

  In FIG. 10, the coordinates of the chart are displayed on an angle scale (the units of the vertical axis and the horizontal axis are angles). In the conventional Hess chart, the coordinates of the chart were set as the length scale, and the grids indicating the angles were formed as unequally-spaced curves. The interval is a straight line. This is because the movement of the eyeball is essentially a rotational movement, and is described by an angle, not a length. Note that, as shown in FIG. 10, the scale conversion is not performed, and the display may be performed on the length scale in the same manner as the conventional Hess chart.

  Further, in the present embodiment, the visual field range that can be inspected is, for example, −35 degrees to +35 degrees in all directions. This is a value that is changed depending on the size of the display unit (display unit 204 in FIG. 5 described later) of the subject inspection apparatus 32 and the distance from the display unit to the subject, so that it is appropriately changed. Or may be fixed.

  In step S34, the multiple image inspection processing unit 172 of the multiple image inspection unit 153 generates inspection data for inspection. This inspection data is data for displaying a target (square frame) and a pointer on the display unit 204 of the subject inspection apparatus 32 in order to perform a double image inspection. , And the position, and the data that specifies the color and size of the pointer (the position of the pointer is not included because it is moved by an operation on the operation input unit 201 of the test device 32 for a subject). The inspection data for this inspection is data newly generated by the multiple image inspection processing unit 172 based on the parameters processed by the parameter processing unit 171 (based on information unique to the subject). Is also good. The inspection data may be generated and stored in advance as data for a multiple image inspection. Further, the inspection data may be generated based on a condition set by a condition setting process described later. For example, the inspection data is data for sequentially displaying nine positions as a multiple image inspection, and is the first inspection data for displaying the first position to the ninth position for displaying the ninth position. Consists of inspection data.

  In step S35, the inspection data transmitting unit 159 transmits the inspection data for the inspection generated by the multiple image inspection processing unit 172. Specifically, when the target image data included in the inspection data generated in the process of step S34 is data for sequentially displaying nine positions, the inspection data transmitting unit 159 determines the first 1 First inspection data for displaying images of the target and the pointer at the two positions are transmitted to the subject inspection apparatus 32 via the cable 33. That is, the test data transmission unit 159 transmits a part of the test data generated in the process of step S34 to the subject inspection apparatus 32.

  On the other hand, the subject inspection apparatus 32 receives the first inspection data and displays an image based on the first inspection data on the display unit 204. In the case of the multiple image inspection, for example, nine positions are sequentially indicated by a red square frame (target), and the subject performs the inspection by clicking at a point overlapping the square frame with a green circle frame (pointer). Therefore, the first inspection data has a red square frame at the position of 10 degrees to the right and 10 degrees above (hereinafter such a state is described as (R, U) = (10, 10)). This is data to be displayed. At this time, the subject is looking at the display unit 204 with the left eye via the green lens and looking at the display unit 204 with the right eye via the red lens. Then, the subject moves a pointer (circular frame) 380, which moves with the movement of the operation input unit 201, to a red target (square frame) which is a display based on the first test data displayed on the display unit 204. Click (specify the position of the pointer) at the point where it appears to overlap. When the pointer (circle frame) overlaps the target (square frame) as the appearance of the subject, the figure of the pointer (in this case, a circle-shaped figure) surrounds the target (square frame). . As a result, the position of the pointer (circular frame) with respect to the target can be accurately determined. Operation input data input by the subject to the operation input unit 201 of the subject inspection apparatus 32 (in this case, data indicating the position at which the subject clicked the operation input unit 201 (the position of the designated pointer) (Hereinafter, referred to as first operation input data) is supplied to the inspector inspection apparatus 31 via the data transmission unit 207.

  Therefore, in step S36, the test data receiving unit 160 transmits operation input data (the position of the designated pointer, that is, the operation input data indicating the position of the pointer at the time of the click) from the subject inspection apparatus 32. It is determined whether or not it has been sent, and waits until it is sent. When it is determined that the operation input data has been transmitted from the subject inspection apparatus 32, the process proceeds to step S37, and the test data receiving unit 160 determines that the operation input data (first time) In step S36, the first operation input data for the first inspection data is received. The received operation input data is supplied to the multiple image inspection processing unit 172 via the main control unit 152. The multiple image inspection processing unit 172 causes the display unit 156 to display an image corresponding to the operation input data on the display unit 156 via the display control unit 155, as shown in FIG. In the figure, portions corresponding to those in FIG. 10 are denoted by the same reference numerals, and description thereof will be omitted because it is repeated.

  In FIG. 11, points 401 to 405 indicated by crosses indicate the positions of the pointer designated by the subject, that is, points indicating the center of the pointer 380 in a circular frame at the time when the pointer is clicked. Reference numerals 416 to 419 indicate points that have not yet been selected by the subject, that is, points corresponding to places that will be transmitted to the subject inspection apparatus 32 and displayed. In the case of FIG. 11, it is indicated that the processing of steps S35 to S38 has been repeated five times because the subject has already selected five places 401 to 405.

  In step S38, the multiple image inspection processing unit 172 determines whether all inspections have been completed. Specifically, the multiple image inspection processing unit 172 transmits all the inspection data (inspection data including the first inspection data to the ninth inspection data) representing the nine positions generated in step S34, and It is determined whether all the operation input data (first operation input data to ninth operation input data) have been received. If it is determined that the inspection has not been completed, the process returns to step S35, and the subsequent processing is repeated. Specifically, the second to ninth inspection data are sequentially transmitted (a part of the inspection data is sequentially transmitted), and the second to ninth operation input data input to the subject inspection apparatus 32 are sequentially transmitted thereto. Is received and the result is displayed. As a result, all nine locations have been input (selected) by the subject, and the nine cross-points are displayed (see later-described cross-points 401 to 409 in FIG. 12).

  If it is determined in step S38 that all the inspections have been completed, in step S39, the multiple image inspection processing unit 172 instructs the subject inspection apparatus 32 to end the inspection. Specifically, the multiple image inspection processing unit 172 transmits, via the inspection data transmission unit 159, data for instructing termination of the inspection performed by the multiple image inspection processing unit 172 to the subject inspection apparatus 32. The subject inspection apparatus 32 receives this, and ends the processing (step S76 in FIG. 15 described later). After that, based on the instruction from the multiple image inspection processing unit 172, the display unit 156 displays, for example, a button 373 displayed as a result display in FIG. 11, a button 374 displayed as a print, a button 375 displayed as a save, A button 376 indicating "end" and a button 377 indicating "condition setting" are displayed by solid lines. That is, the multiple image inspection processing unit 172 makes these buttons 373 to 377 selectable.

  In step S40, the multiple image inspection processing unit 172 determines whether an inspection result display has been instructed. After the process of step S39, when the examiner selects the button 373 displayed as the result display displayed on the display unit 156, the multiple image inspection processing unit 172 determines that the inspection result display has been instructed. . When it is determined that the inspection result display has been instructed, the multiple image inspection processing unit 172 causes the display unit 156 to display an inspection result display option in step S41. At this time, the display unit 156 displays an inspection result display option on the screen as shown in FIG.

  In FIG. 12, the positions of the first to ninth examination data designated (clicked) by the subject are displayed as points 401 to 409 indicated by crosses. That is, the position of the pointer designated by the operation input from the subject with respect to the positions of the first to ninth targets is displayed. Further, as the (inspection) result display option 440, an option button 451 for selecting an inspection side, an option button 461 for selecting the presence or absence of a connection line, and a button 471 indicating OK are displayed. The examiner selects one of the right eye and the left eye with the option button 451, and selects the presence or absence of a connection line with the option button 461. Further, the examiner clicks the button 471 (specifically, clicks with the mouse 51 as the operation input unit 201) to determine the setting of the result display option (parameter).

  In step S42, the operation input unit 151 receives an input of the setting of the inspection result display option 440 displayed on the display unit 156 of FIG. 12 and supplies this to the parameter processing unit 171 via the main control unit 152. The parameter processing unit 171 holds and processes such display options as parameters in addition to the parameters received in step S31 described above.

  In step S43, the display unit 156 displays the inspection result. Specifically, the multiple image inspection processing unit 172 displays the inspection result based on the input of the display option setting received in the processing of step S42. For example, in the result display option 440 of FIG. 12, when the left eye is set as the examination side and “Yes” is selected as the connection line, the display unit 156 displays the examination result as shown in FIG. The screen data of the inspection result is generated by the multiple image inspection processing unit 172.

  FIG. 13 shows square frames 411 to 419, which are the positions of the nine targets corresponding to the nine inspection data generated in the process of step S34 in FIG. 8, and the positions of the pointers designated for the respective targets. Are indicated by points 401 to 409 indicated by crosses indicating the symbols. Further, points 401 to 409 indicated by crosses are connected by lines (connected lines). As described above, the display unit 156 displays the relationship between the position of the target as the target for specifying the position with the pointer moving by the operation of the subject and the position of the pointer specified by the operation input from the subject. Is displayed, the examiner can easily see the result of the examination. In addition, the inspection result can be easily determined. Further, a quantitative inspection can be performed.

  If it is determined in step S40 that the result display has not been instructed, or after the process in step S43, the process proceeds to step S44, and the multiple image inspection processing unit 172 determines whether or not printing has been instructed. That is, when the button 375 displayed on the display unit 156 and displayed as print is selected by the examiner, the multiple image inspection processing unit 172 determines that printing has been instructed. If it is determined that printing has been instructed, in step S45, the multiple image inspection processing unit 172 prints the print data (for example, the image data of the print result or the text data of the print result) that is the data to be printed based on the data of the inspection result. Print). Specifically, the multiple image inspection processing unit 172 transmits the print data to the printer 34 via the print data transmission unit 161 (and the cable 35). The printer 34 prints an image (or a document) based on the print data on paper and outputs it.

  By the processing in step S45, for example, an image as shown in FIG. 14 is printed. FIG. 14 shows a chart 551 of the test result of the left eye and the test result of the right eye. Further, the ID, name, and examination date of the subject are displayed. The examiner (ophthalmologist) can judge the examination result by looking at the printed paper. Of course, the charts of the test results of the left and right eyes may be printed on different papers.

  When it is determined in step S44 that printing has not been instructed, or after the processing in step S45, in step S46, the multiple image inspection processing unit 172 determines whether or not data saving has been instructed. That is, when the examiner selects the button 375 displayed on the display unit 156 and displayed as save, the multiple image inspection processing unit 172 determines that the instruction to save the inspection data has been issued. If it is determined that the storage of the inspection data has been instructed, in step S47, the multiple image inspection processing unit 172 stores the data of the inspection result as a file. Specifically, the multiple image inspection processing unit 172 causes the file storage unit 157 to store the inspection result data as, for example, a CSV format file via the main control unit 152. At this time, the subject ID, the subject name, the examination date and time, etc. are added to the file and stored so that they can be referred to as search parameters. In addition, this file includes data of the right eye / left eye, examination conditions (all parameters), and examination results, in addition to the examinee ID, the examinee name, and examination date and time. At this time, file data is transmitted to the file storage unit 205 of the subject inspection apparatus 32 so as to be stored as a backup. Thus, even if a file stored in the file storage unit 157 of the inspector inspection apparatus 31 is deleted, the data can be read.

  If it is determined in step S46 that the instruction to save the data has not been issued, or after the processing in step S47, the processing ends. Note that, in FIG. 12, for example, even when the button 376 indicating “end” is pressed, the processing is ended. Thereafter, the process returns to step S13 in FIG. 6 described above, and proceeds to step S11.

  8 and 9, inspection data for multiple image inspection is generated, transmitted to the subject inspection apparatus 32, and displayed. Then, the operation input data input by the subject inspection apparatus 32 is received, and the result is displayed, printed, or saved as a file. Thus, the double-image inspection can be performed by reading the position of the pointer operated by the subject directly as data instead of plotting the position of the pointer by the examiner by hand.

  Also, for example, when the subject has a green lens on the left eye and a red lens on the right eye, the display unit 204 can display the image without changing the color of the lens depending on the eye to be examined. Since it is only necessary to reverse the colors of the target (square frame) and the pointer (round frame) to be displayed, the labor of the inspection can be further reduced. That is, the multiple image inspection processing unit 172 generates inspection data according to the subject and the eye to be inspected in the process of step S34, so that the inspection can be performed quickly and quantitatively.

  In the processing of steps S36 and S37, the operation input data is handled as data indicating a click (designating the position of the pointer). In addition to the data indicating the click, the data indicating the movement of the pointer is also combined. When the input data is treated as operation input data and the operation input data is data indicating the movement of the pointer, the position of the pointer is moved corresponding to the data and displayed, and the operation input data is data indicating a click. In this case, a position corresponding to the position of the pointer at the time of clicking on the data (the position of the designated pointer) may be displayed as a cross.

  Next, an inspection process performed by the subject inspection apparatus 32 in FIG. 5 that is performed in correspondence with the processes in FIGS. 8 and 9 will be described with reference to the flowchart in FIG. This process is started when the test program of the subject test apparatus 32 is started (actually, this program is started by the tester).

  In step S71, the data receiving unit 206 receives inspection data for inspection. This inspection data is, for example, data transmitted by the inspector inspection apparatus 31 in step S35 of FIG. The data receiving unit 206 supplies the received inspection data to the main control unit 202.

  In step S72, the display unit 204 displays an image based on the inspection data. Specifically, the main control unit 202 supplies the inspection data to the display control unit 203, and the display control unit 203 controls the display unit 204 to display an image based on the inspection data. On the other hand, the display unit 204 displays an image as shown in FIG. In FIG. 16, a circular frame pointer 651 that operates in response to the operation input of the subject to the operation input unit 201 is displayed on the display unit 204 against the gray back surface. Further, a square frame target 661 based on the inspection data is displayed. The target 661 is displayed, for example, at a location corresponding to the above-described square frame 411 in FIG. That is, the target 661 is a square frame corresponding to the first inspection data transmitted in the first process of step S35 in FIG. The subject clicks (designates the position of the pointer) at a point where the pointer 651 appears to overlap the target 661 of the square frame. As described above, when the pointer (round frame) 651 overlaps the square frame (target) 661, the figure of the pointer 651 (in this case, a round figure) surrounds the square frame (target) 661. Become. Thus, the position of the pointer (round frame) 651 with respect to the target (square frame) 661 can be determined precisely. As a specific example, since the operation input unit 201 is the mouse 51 shown in FIG. 2, the subject moves the pointer 661 using the mouse 51 and overlaps the square frame 661. Click at the position (at the position where the square frame (target) 661 is surrounded by the round frame of the pointer 651).

  In step S73, the operation input unit 201 determines whether or not an operation has been input by the subject, and waits until an operation (for example, a click operation) is input. When it is determined in step S73 that an operation has been input by the subject, in step S74, the operation input unit 201 receives an operation input from the subject.

  In step S75, the data transmission unit 207 transmits the operation input data (for example, data indicating the clicked position) received in the processing in step S74 to the inspector inspection apparatus 31. Specifically, the operation input unit 201 supplies operation data based on the operation input received in the process of step S74 to the main control unit 202, and the main control unit 202 transmits the operation data to the inspector inspection apparatus 31. To the data transmission unit 207, and the data transmission unit 207 transmits the operation input data.

  In step S76, the main control unit 202 determines whether or not the end is instructed by the examiner inspection apparatus 31. Specifically, the main control unit 202 determines whether or not data for instructing termination is received from the examiner inspection apparatus 31 via the data receiving unit 206. That is, this process is a process for step S39 in FIG. 8 described above, and it is determined as YES when the process of step S39 is performed. If it is determined in step S76 that the termination has not been instructed, the process returns to step S71, and the subsequent processing is repeated. That is, the next inspection data (for example, the second inspection data) is received and displayed, and the data of the operation input corresponding thereto is transmitted. If it is determined in step S76 that termination has been instructed, the process is terminated.

  The multiple image inspection processing in the inspector's inspection device 31 and the inspector's inspection device 32 is performed by the processing in FIGS. 8, 9, and 15. Conventionally, the examiner has manually generated the Hess chart, whereas the chart is generated simply by inputting and instructing parameters to the subject inspection apparatus 32, so that the inspection can be performed without much trouble. It can be performed. Further, the inspection result data can be easily printed or saved as a file. Further, the inspection setting can be changed only by operating parameters and display options. In other words, the inspection can be performed quickly and quantitatively.

  Although the inspection data is transmitted as the first to ninth inspection data in the processes of FIGS. 8, 9, and 15, the inspection data may be transmitted collectively. In addition, although the data at nine locations are used, in practice, inspection may be performed at 25 locations depending on the case of inspection. These can be appropriately changed by setting parameters and the like.

  Next, with reference to the flowchart of FIG. 17, a description will be given of the processing when the examiner selects the condition setting and the displayed button 378 of FIG. 13 displayed on the display unit 156 of FIG. This processing is executed in parallel with the processing of FIGS. 8 and 9, and is executed when the button 378 is in a selectable state (state shown by a solid line) and when the examiner selects it. This is the process to be performed.

  In step S91, the operation input unit 151 receives a condition setting command. Specifically, an operation input for selecting the button 378 displayed as the condition setting in FIG. 13 is received.

  In step S92, the display unit 156 displays a condition setting screen as shown in FIG. The inspection condition setting box 700 in FIG. 18 includes an option button 710 for selecting a target presentation method, an option button 720 for selecting a background, an option button 730 for selecting a target luminance, an option button 740 for selecting a cursor luminance, and a display on a display. In addition to an option button 750 for selecting a method and an option button 760 for selecting a target cursor size, a button 771 displayed as “Yes” for saving all these setting conditions, and a button for not saving the conditions A button 772 labeled "No" is displayed.

  With the option button 710, one of the target presentation methods can be selected from manual, automatic, or full presentation (for example, the processing method of steps S34 to S38 can be selected), and the option button 720 can be selected. Then, one of light, medium, and dark can be selected as the background (for example, the background of the display unit 204 in FIG. 16). With the option button 730, the target (for example, the square frame 661 in FIG. 16) can be selected. One of high, medium, and low can be selected as the luminance of the cursor. The option button 740 displays the luminance of the cursor (for example, the pointer 651 in FIG. 16) as one of high, medium, or low. The option button 750 allows the user to select an effective display area, a maximum display resolution, an eye-screen Can be set away, the option button 760, as the target cursor size (e.g., size of the rectangular frame 661 of FIG. 16), large, medium, or one of the small can be selected.

  In step S93, the operation input unit 151 receives an operation input from the examiner on the condition setting screen shown in FIG. 18, and reflects the condition input on the condition setting screen in step S94. Thereafter, the processing is terminated.

  By the processing of FIG. 17, the examiner can freely set these conditions. In addition, these conditions can be immediately reflected, and the inspection can be continued and performed. These conditions are stored as parameters in the file stored in step S47 of FIG. 9 described above. Further, the parameter processing unit 171 may store these parameters as parameters for the next examination, or may store the parameters so that the same subject is performed under the same conditions. You may do so.

  Next, the eye position inspection processing in step S15 in FIG. 6 will be described with reference to the flowcharts in FIG. 19 and FIG. The eye position test is a test for checking whether the positions of the left and right eyes are normal or not. The eye position test is performed at a predetermined position (for example, a display position) on the display unit 204 of the subject inspection apparatus 32 in front of the subject. This is performed by displaying a red square frame (target) at the center of the unit 204) and allowing the subject to operate the frame so as to overlap (using the mouse 51) with a green circle pointer.

  In step S121, the operation input unit 151 receives an input of a parameter from the examiner. For example, the eye position examination processing unit 182 of the eye position examination unit 154 causes the display unit 156 to display a screen as shown in FIG. 21 via the main control unit 152 and the display control unit 155.

  In the center of the display unit 156 in FIG. 21, an image of a pointer operated by the subject using the operation input unit 201 of the subject inspection apparatus 32 and a target serving as a target for specifying a position with the pointer (Field) 850 in which the image is displayed. In the upper part of FIG. 21, an examination date 851 displayed as January 21, 2004, an input field 852 for inputting a subject ID, a name field 853 for inputting a subject name, and confirmation and display Button 854 is displayed. Further, on the left side of the display unit 156, an option button 860 displayed as a left eye and a right eye for selecting an eye to be inspected, a button 870 displayed as a start of the inspection, a button 871 displayed as a return, and a display as an interruption of the inspection Button 872, a result display button 873, a print button 874, a save button 875, an end button 876, and a condition setting button 877 are displayed. ing. The buttons 854 and 877 are displayed as solid lines because they are currently selectable by the examiner, and the buttons 870 to 876 are displayed as broken lines because they are items that cannot be currently selected by the examiner. On the right side of the drawing, a frame 880 for displaying the test result, a frame 881 for inputting the distance between the subject's eye and the screen, and a button 882 for switching the target ON / OFF are displayed.

  In step S121, the examiner inputs the subject ID (eg, aaa) in the input field 852, the subject name (eg, Ichiro Yamada) in the input field 853, and the right or left eye of the option button 860 on the test side. (For example, the left eye) and a parameter in a frame 881 for inputting an eye-screen distance, and an operation input to select the button 854 displayed as confirmation is performed on the operation input unit 151. The operation input unit 151 receives the input of the parameter, and is supplied to the parameter processing unit 181 of the eye position examination unit 154 via the main control unit 152. Note that the eye-screen distance is not set every time as a parameter, but may be a default value.

  In step S122, the parameter processing unit 181 determines whether or not all the essential parameters have been input by the examiner. In the case of the example of FIG. 21, since the check of the input fields 852 and 853 (the subject ID and the subject name) and the option button 860 on the examination side are essential parameters, the parameter processing unit 181 sets these essential parameters Is determined by the examiner. If it is determined that all the essential parameters have not been input, the process returns to step S121, and the subsequent processes are repeated.

  When it is determined in step S122 that all the essential parameters have been input, the eye position examination processing unit 182 sets the button 870 indicating that the examination is started in FIG. ). Then, in step S123, the eye position examination processing section 182 determines whether or not the start of the examination is instructed by the examiner, and waits until the start of the examination is instructed. Specifically, when the subject selects the button 870 indicating that the examination has started, the eye position examination processing unit 182 determines that the examination has been commanded by the examiner.

  When it is determined in step S123 that the start of the test has been instructed (that is, when it is determined that the button 870 has been selected), in step S124, the eye position test processing unit 182 generates test data for the test. I do. Inspection data to be generated includes, for example, data indicating the position, color, and size of the target, data indicating the display of the target, and data indicating the color of the pointer (the size may be included). It is included. In step S125, the eye position inspection processing unit 182 transmits the data indicating the position of the target, the data for instructing the display of the target, and the inspection data indicating the color of the pointer to the inspection data transmitting unit 159 via the main control unit 152. Send from. Note that the test data generated in the process of step S124 may be generated and stored in advance as data for an eye position test. Further, the examination data may be data newly generated by the eye position examination processing unit 182 based on the parameters processed by the parameter processing unit 181 (based on information unique to the subject). Further, the inspection data may be generated based on the condition set by the condition setting process (the process of FIG. 17 described above). For example, the inspection data is data for displaying a target at a predetermined position.

  The test data transmitted in step S125 is received by the subject test apparatus 32, and an image based on the test data is displayed. That is, the display unit 204 of the test device for a subject 32 displays a gray background and a red square frame at the center as a target (for example, step S72 in FIG. 15).

  In step S126, the eye position examination processing section 182 determines whether or not the examiner has turned ON. Specifically, when the examiner clicks (selects) the ON-OFF button 882 via the operation input unit 151, the eye position examination processing unit 182 determines that ON has been instructed. If it is determined in step S126 that ON has been instructed, that is, if the ON-OFF button 882 has been clicked, the eye position examination processing unit 182 performs the examination data transmission unit 159 via the main control unit 152 in step S127. Transmits an instruction to display a pointer (ON instruction) to the subject inspection apparatus 32.

  On the other hand, the subject inspection apparatus 32 receives the ON command (command to display the pointer) and displays an image (pointer) based on the command on the display unit 204. For example, since the display unit 204 has already displayed a gray background and a red square frame as the target in the center corresponding to the processing of step S125, the display unit 204 further moves the pointer (based on the ON command) to this. indicate. That is, before the process of step S127, only the target image is displayed on the display unit 204. The examiner operates the operation input unit 201 with respect to the subject so that the round frame (pointer (cursor)) overlaps the square frame (target), and clicks the pointer with the operation input 201 at the overlapping position. Give instructions. On the other hand, the subject operates the operation input unit 201 so that a pointer (circular frame) operable by the operation input unit 201 overlaps a target (square frame) displayed on the display unit 204 in front. Then, the operation input unit 201 is clicked (operated) at the overlapping position. Operation input data (for example, data indicating the movement of the pointer or data indicating the click operation) input by the subject to the operation input unit 201 of the subject inspection apparatus 32 is transmitted via the data transmission unit 207. And supplied to the inspector inspection device 31. That is, in this case, the “operation” in step S73 of FIG. 15 described above includes not only the click but also the operation of the movement of the pointer.

  Therefore, in step S128, the test data receiving unit 160 determines whether or not the operation input data has been transmitted from the subject inspection apparatus 32, and waits until the operation input data is transmitted. When it is determined that the operation input data has been transmitted from the subject inspection apparatus 32, the process proceeds to step S129, and the test data receiving unit 160 receives the operation input data from the subject inspection apparatus 32. . The received operation input data is supplied to the eye position examination processing unit 182 via the main control unit 152. At this time, the eye position examination processing unit 182 causes the display unit 156 to display the coordinates for the operation input data via the display control unit 155. For example, the display unit 156 displays an image as shown in FIG.

  FIG. 22 shows the parameters (subject ID, subject nomination, examination side, eye-screen distance) accepted in the process of step S121 described above. In the frame (field) 850 indicating the position of the pointer operated by the subject, R (right), L (left), and U (up) are included in the frame 850, as in FIG. , D (bottom) and numerical values indicating angles are displayed. Further, in the frame 850, a square frame 890 which is a target as a target for specifying a position with a pointer, and a pointer 891 operated and moved by the operation input unit 201 of the subject inspection apparatus 32. Is displayed. In this way, the target (square frame) 890 and the pointer (cursor, round frame) 891 operated by the subject are displayed, so that the examiner can see the movement of the subject's pointer 891 with respect to the target. Can be. The position of the pointer 891 displayed on the display unit 156 moves in accordance with the movement of the pointer by the subject. That is, the position of the pointer 891 moves based on the received operation input data.

  Therefore, in step S130, the eye position examination processing unit 182 determines whether or not the operation input data received in step S129 is data indicating a click (not data indicating movement of a pointer). In step S130, when it is determined that the operation input data is not data indicating a click (when it is determined that it is data indicating movement of a pointer), or in step S128, the operation input data is If it is determined that the data has not been transmitted, the process returns to step S128, and the subsequent processes are repeated. That is, in the processing of steps S128 to S130, when the pointer is moved by the subject, the data corresponding to the movement is received as the operation input data, and the display is updated. Is repeated until a click operation is performed.

  If it is determined in step S130 that the operation input data from the subject test apparatus 201 is a click, in step S131, the eye position test processing unit 182 turns off the display of the pointer for the test. Send command data. As a result, the pointer displayed on the display unit 204 of the subject inspection apparatus 32 is turned off (turned off).

  In step S132, the eye position examination processing unit 182 compares one examination result (the coordinates of the position of the clicked cursor with respect to the position of the target based on the examination data) acquired in one process of steps S126 to S131. Are displayed on the display unit 156 via the display control unit 155. For example, in FIG. 22, the pointer 891 disappears, and the target 890 and a cross (cross) indicating the clicked position are displayed.

  In step S133, the eye position examination processing unit 182 determines whether the number of examinations has reached the set number. In the eye position examination, for example, the number of examinations for the left eye and the right eye is set to four, respectively, and it is determined whether or not the number has been reached. The set number of times may be set by the examiner or may be set in advance. If it is determined in step S133 that the number of inspections has not yet reached the set number, the process returns to step S126, and the subsequent processing is repeated. For example, when the set number of times is set to four times for the left eye and four times for the right eye, the process is repeated until the inspection is performed for the set number of times. In other words, the process of instructing ON, receiving the operation input data indicating the click, and displaying the result is repeated.

  Note that the processing in step S133 is equivalent to determining whether or not all the inspections have been completed. Specifically, as in step S133, the end is determined not only by the number of examinations but also by an input to the operation input unit 151 by the examiner (for example, an input for instructing the end of the examination by the examination interruption button 872). May be.

  When the operation input data is not transmitted from the subject inspection apparatus 32, the examiner clicks the ON-OFF button 882 to forcibly display the operation input data on the display unit 156 of the subject inspection apparatus 32. The pointer can be turned off (erased) to proceed with the process.

  If it is determined in step S133 that the number of examinations has reached the set number of times, in step S134, the eye position examination processing unit 182 instructs the subject examination device 32 to end the examination. Specifically, the eye position examination processing unit 182 transmits, via the examination data transmission unit 159, data instructing the end of the examination by the eye position examination processing unit 182 to the subject inspection apparatus 32. The subject inspection apparatus 32 receives this, and ends the processing (step S76 in FIG. 15). Thereafter, the display unit 156 displays, for example, the buttons 873 to 877 in FIG. 22 with solid lines based on the instruction from the eye position examination processing unit 182. That is, these buttons 873 to 877 are made selectable.

  Note that the subsequent processing in steps S135 to S142 is basically the same as the processing in steps S40 to S47 in FIG. 9 described above, and thus a detailed description thereof will be omitted and will be briefly described.

  In step S135, the eye position examination processing unit 182 determines whether or not the examination result display has been instructed. If it is determined that the examination result display has been instructed, in step S136, the eye position examination processing unit 182 performs the display. The unit 156 displays an inspection result display option. In the case of the eye position examination process, an option for displaying the examination result is appropriately displayed as an option.

  In step S137, the operation input unit 151 receives the input of the setting of the inspection result display option, and supplies this to the parameter processing unit 181 via the main control unit 152.

  In step S138, the display unit 156 displays the inspection result. In the case of the eye position test, the display unit 156 displays a screen as shown in FIG. In the figure, portions corresponding to those in FIG. 22 are repeated, and the description thereof is omitted.

  In the frame 850 in FIG. 23, a position clicked by the subject, that is, an X mark indicating the test result is displayed. The number of crosses is the above-mentioned set number of times (8 in this case). For example, the right eye test result is displayed in red, and the left eye test result is displayed in green. In the frame 880, an inspection result obtained by repeating the processing of steps S126 to S133 is displayed. The test results include, from the left, the number of tests, the eye-screen distance, L (left) or R (right) indicating the side of the eye to be tested, and the horizontal direction (horizontal axis position) and the vertical direction (vertical axis position). ) Respectively. The position in the horizontal direction and the position in the vertical direction are values indicating the displacement of the eyes. The greater the absolute value of this value, the greater the displacement of the eyes, and the sign indicates the direction of the “deviation”. In the case of the example of FIG. 23, the first row is the first examination, the eye-screen distance is 25 cm, the horizontal position is 0.0, and the vertical position is 0.6 ( That is, it is 0.6 degrees on the upper side). Similarly, the second row is the second test, the eye-screen distance is 25 cm, the horizontal position is -0.6 (i.e., 0.6 degrees on the L side), and the vertical This indicates that the position in the direction is 0.6 (that is, 0.6 degrees upward). In other words, the frame 880 displays the result of the inspection performed eight times, that is, the result of repeating the processing of steps S126 to S133 eight times. As described above, by displaying the image and the character indicating the relationship between the operation input from the subject and the image based on the inspection data on the display unit 156, the eye inspection can be quantitatively performed. In addition, the subject changes or moves the color of the glasses lens by generating inspection data that changes the target and the pointer displayed on the display unit 204 based on the parameter of the eye-screen distance. Since the necessity is eliminated, the inspection can be performed more easily.

  If it is determined in step S135 that the result display has not been instructed, or after the process in step S138, the process proceeds to step S139, and the eye position examination processing unit 182 determines whether or not printing has been instructed. For example, the determination is made based on whether or not the button 874 displayed on the display unit 156 and displayed as print is selected by the examiner. When printing is instructed, in step S140, the eye position inspection processing unit 182 outputs print data (for example, image data of the print result or text data of the print result) which is data to be printed based on the data of the test result to the printer 34 is printed.

  When it is determined in step S139 that printing has not been instructed, or after the processing in step S140, in step S141, the eye position examination processing unit 182 determines whether or not saving of data has been instructed, and If it is determined that the saving is instructed, in step S142, the eye position examination processing unit 182 saves the data of the examination result as a file. Specifically, the eye position examination processing unit 182 stores the data of the examination result as a file in the file storage unit 157 via the main control unit 152.

  If it is determined in step S141 that data storage has not been instructed, or after the process of step S142, the process ends. In FIG. 23, for example, even when the button 876 indicating “end” is pressed, the processing is ended. Thereafter, the process returns to step S15 in FIG. 6 described above.

  19 and 20, the test data for the eye position test is generated, transmitted to the subject test apparatus 32, and displayed. Then, the operation input data input by the subject inspection apparatus 32 is received, and the result is displayed, printed, or saved as a file. Thus, the eye position test can be performed not by handwriting by the examiner but by data operated by the examinee himself.

  Note that the inspection processing in the subject inspection apparatus 32 corresponding to FIGS. 19 and 20 is the same as the processing in FIG. 15 described above, and a description thereof will be omitted. However, after the processing of step S71 and step S72 of FIG. 15 is executed for the processing of step S125 of FIG. 19, the processing of step S127 and step S72 of FIG. Is performed, and the process proceeds to the process of step S73. That is, the processes of step S71 and step S72 are respectively executed based on the inspection data and the ON command.

  Further, the condition setting processing at the time of the eye position examination in the examiner's examination apparatus 31 is the same as the processing of FIG. 17 described above, and the description of the processing is omitted. However, the screen set in the condition setting process is slightly different from that in FIG. 18 described above, and thus will be described with reference to FIG.

  FIG. 24 is a diagram showing an example of a screen displayed on the display unit 156 in step S92 of the condition setting process of FIG. 17 executed in parallel with the above-described eye position inspection process of FIGS. 19 and 20. In the inspection condition setting box 900 in FIG. 24, an option button 910 for selecting the background luminance, an option button 920 for selecting the target cursor size, an option button 930 for selecting the cursor luminance, an option button 940 for selecting the target luminance, and In addition to the option button 950 for selecting the display method of the subject-side display, a button 971 displayed as “Yes” for saving all these setting conditions, and a “No” for not saving the conditions "Button 972 is displayed.

  With the option button 910, one of light, medium, and dark can be selected as the background (for example, the background of the display unit 204). With the option button 920, the target cursor size (for example, the square frame in FIG. 16) can be selected. One can be selected from large, medium, or small as the cursor size in the eye position test corresponding to 661. The option button 930 allows the cursor (for example, the eye corresponding to the pointer 651 in FIG. 16) to be selected. One of high, medium, and low luminances of the cursor for the position test can be selected from among high, medium, and low. The option button 940 displays the target (for example, the eye position test corresponding to the square frame 661 in FIG. 16). In this case, one of high, medium, and low luminances can be selected as the luminance of the target. As a display method on the side of the display, it is possible to set the effective display area and the maximum display resolution.

  According to the above, test data for an eye test is generated by the tester's test apparatus 31, and based on the test data, a target and a pointer that are targets for specifying a position with a pointer that is moved by operation of a subject Is an image that shows either the target or the pointer to the left eye of the subject, does not show the other, shows the other to the subject's right eye, and shows no subject. The operation input for displaying the position of the pointer from the subject, which is displayed on the inspection device 32 for the subject, is received by the inspection device 32 for the subject, and the position of the target and the position of the pointer designated by the received operation input (For example, the frame 880 in FIG. 23) or an image (for example, the frame 350 in FIG. 13 or the frame 850 in FIG. 23) indicating the relationship with the subject is displayed on the subject inspection apparatus 32. Shall, together with know quickly test results, it is possible to perform a quantitative test. That is, a quick and quantitative test result can be obtained.

  In addition, the examiner does not need to write down the points indicated by the subject by hand, and can perform the examination quickly and easily. Furthermore, for the summary display of the test results, for example, it is not necessary to draw a connecting line of points operated and input by the subject by hand, so that the test time can be reduced.

  Further, since two inspections, that is, the double image inspection and the eye position inspection, can be performed by one inspection system, the inspection apparatus can be reduced in size.

  In addition, since the examiner's examination apparatus 31 receives parameters for the eye examination and generates examination data based on the accepted parameters, the examination parameters can be easily changed, and the examination parameters can be changed according to the subject. Inspection can be performed quickly and easily.

  Furthermore, the examiner's examination apparatus 31 generates examination data that changes the target and the pointer displayed on the display unit 204 based on the parameter of the eye-screen distance. It is not necessary to move the distance finely, and the inspection can be performed more easily.

  The items of the ophthalmic examination can also be realized by installing a program for executing the above-described processing. Can be easily realized by installing.

  Furthermore, since data (test result data) indicating the relationship between the position of the target and the position of the designated pointer is stored as a file, it can be easily searched based on the ID of the subject and the like. The test results can be used for examining changes over time of the same subject, for comparing a plurality of subjects, and for obtaining statistical data.

  In addition, since the coordinates of the point indicated by the subject are acquired and displayed by the examiner's inspection device 31, the coordinates of the point indicated by the subject are compared with the case where the examiner inputs data as data. Even so, the inspection can be performed without much trouble.

  Further, by inverting the colors of the target 650 and the pointer 651 displayed on the display unit 204 of the subject inspection apparatus 32, the subject can perform the inspection without inverting the color of the lenses of the glasses worn. Inspection can be performed more quickly.

  In the above example, the case where the present invention is applied to the inspection system 20 shown in FIG. 3 has been described. However, the present invention is not limited to this, and a display for the subject to view the screen and input the result is provided. The present invention can be applied to a single device including a pointing device and a display provided with an input device for the examiner to set examination items. That is, the present invention can be applied not only to the plurality of devices constituting the inspection system 20 of FIG. 3 but also to an inspection device in which these plurality of devices are mounted on one device.

  In the inspection system 20 shown in FIG. 2, the inspector's inspection device 31 and the examinee's inspection device 32 are directly connected by the Ethernet (registered trademark) cable 33. ) May be connected via a LAN (Local Area Network) or the like.

  Further, in the above example, the lenses for the eye examination are the red lens and the green lens, but these may be changed as appropriate. In this case, the colors of the target and the pointer displayed on the display unit 204 are changed according to the color of the lens. Further, the lens may have a power for a person with bad eyes.

  Further, in the above example, it is described that the test is performed by attaching a colored lens (color filter glasses) to the subject for the eye test. However, the present invention is not limited to this. Any configuration may be used as long as it can be seen by any one of the eyes and the pointer can be seen by the other eye.

  As a specific example, by causing the subject to wear glasses using polarizing filters having different right and left deflection directions, the left eye shows either the target or the pointer, and the right eye shows the other. It may be a method of causing the target or the pointer to be shown with the left eye by synchronizing the display by alternately opening and closing shutters (for example, liquid crystal shutters) applied to the left and right eyes. Alternatively, the right eye may be used to make the other visible. Further, a parallax barrier is provided in the display unit, and one of two lights emitted from two adjacent points of the display unit enters the left eye and the other enters the right eye (for example, a three-dimensional liquid crystal display). (Display), the left eye may show either the target or the pointer, and the right eye may show the other. With any of those methods, the subject can show either the target or the pointer with the left eye and the other with the right eye. The target and the pointer are displayed on the display unit 204 of the subject inspection apparatus 32, and operation data based on the movement of the pointer with respect to the operation on the operation input unit 201 by the subject (the operation in which the pointer overlaps the target) is obtained. By doing so, the inspection can be performed.

  In the present embodiment, the required parameters such as the subject ID, the subject name, the effective display area of the display, and the maximum display resolution are determined in the processes in steps S13, S15, and S17 in FIG. Although they are input, they may be input following step S11 of displaying the initial screen.

  Further, in the above example, the examiner's inspection device 31 and the examinee's inspection device 32 are each a personal computer as shown in FIG. 3, but actually, for example, an embedded computer may be used. Good.

  The shape of the target and the pointer is not limited to a square or a circle, but may be any shape.

  The above-described series of processes can be executed by hardware or can be executed by software. When a series of processing is executed by software, a program constituting the software is installed from a network or a recording medium.

  As shown in FIG. 3, this recording medium is not only constituted by a package medium consisting of a removable medium 101 on which the program is recorded, which is distributed in order to provide the program to the user, separately from the computer. And a hard disk including a ROM 82 and a storage unit 88 in which a program is recorded and provided to a user in a state where the program is incorporated in the apparatus main body in advance.

  In this specification, a step of describing a computer program refers to not only a process performed in chronological order according to the described order, but also a process executed in parallel or individually even if not necessarily performed in chronological order. Is also included.
