As described above, when the CPU 74 detects that the switch having the freeze (FREEZE) function assigned to the operation device is ON (S1), it is in the registers FREEZE and OPFREEZE of the CPU I / F 158 of the video processing circuit 55. The FREEZ and OPFRZ bits are turned ON (S2).

  The FREEZ and OPFRZ bits are latched in synchronization with the vertical synchronizing signal VD1, and then control the freeze circuit 155 and the memory 1 (56) and are output to the video processing circuit 57 and the video + compositing process 93 as freeze signals 173 and 174. The freeze process is performed by controlling the enlargement / enhancement / synchronization circuit 163, the memory 2 (58), the synchronization circuit 208, and the memory 6 (101).

  When the Pre-Freeze level is 1 or more in the item Freeze Mode on the system setting screen, the freeze function is pre-freeze processing (S3) and waits for a certain time (for example, 8V when the time between VD1 is 1V) Wait. Wait until the pre-freeze process of the above circuit is completed (S4).

  (Pre-freeze processing: the image having the least color shift is automatically selected from the images in a certain search period immediately before the timing at which the circuits receive ON of the FREEZ and OPFRZ bits, and is frozen. If the Pre-Freeze level is increased, the range of the search period becomes longer, and the number of images that can be selected increases (see Patent Document 5 for details).

  When IHB_ave of the item IHB of the user setting screen is ON (S6), the average value of the IHB value of the area set by the IHBArea of the item IHB of the user setting screen calculated by the image processing circuit 202 is CPU I / F4 (203). And the display information is controlled by the graphic circuit 1 (103) and the graphic processing circuit 2 (212) (S7) and waits until the display is fixed (for example, VD1). If the time between them is 1V, 2V) (S8), the freeze flow is terminated (S9).

  When the level of Pre-Freeze is 0 in the item Freeze Mode on the setting screen, post-freeze processing is performed so that the freeze processing is completed within the freeze time set by the item Freeze (S5).

(Post-freeze processing: Immediately after the timing at which the circuits receive ON of the FREEZ and OPFRZ bits, the smallest image in the search period set by the item Freeze on the setting screen is automatically selected and frozen.)
Although not shown in this flow, when the CPU 74 detects that the switch having the freeze (FREEZE) function assigned to the operation device is turned off, the CPU 74 is in the registers FREEZE and OPFREEZE of the CPU I / F 158 of the video processing circuit 55. After the FREEZ and OPFRZ bits are turned OFF and latched in synchronism with the vertical synchronizing signal VD1, the freeze circuit 155 and the memory 1 (56) are controlled and the video processing circuit 57 and the video + compositing process 93 are used as the freeze signals 173 and 174. And the enlargement / emphasis / synchronization circuit 163, the memory 2 (58), the synchronization circuit 208, and the memory 6 (101) are controlled to perform the freeze release processing.

  In addition, ON / OFF of the freeze may be provided with a dedicated switch on the operation device, or the same switch is toggled (switched as ON → OFF → ON →... Each time it is pressed). Also good.

FIG. 40 (FIGS. 40A and 40B) is a flow showing a recording operation (release) to the photography apparatuses 307 and 356 and the filing apparatuses 308 and 357 among the peripheral devices. Unlike the freeze operation, the release operation is accompanied by an image recording operation. (Shows the operation when Release is selected in the item “Index record” on the system setting screen.)
As described above, when the CPU 74 detects that the switch assigned to the operation device and performs a recording instruction such as a release (RELEASE) function (S11), the endoscope image is not first frozen. (S12), the FREEZ, OPFRZ, RELSE, and OPRLE bits in the registers FREEZE and OPFREEZE of the CPU I / F 158 of the video processing circuit 55 are turned ON (S13).

  The FREEZ, OPFRZ, RELSE, and OPRLE bits are latched in synchronization with the vertical synchronizing signal VD1, and then control the freeze circuit 155 and the memory 1 (56), and the video processing circuit 57 and the video + compositing process as freeze signals 173 and 174 The freeze process is performed by controlling the enlargement / enhancement / synchronization circuit 163, the memory 2 (58), the synchronization circuit 208, and the memory 6 (101).

  When the Pre-Freeze level is 1 or higher in the item FreezeMode on the setting screen, the freeze function is pre-freeze processing (S14), and wait processing is performed for a certain period of time (for example, 8V if the time between VD1 is 1V). The process waits until the pre-freeze process of the circuit is completed (S15).

  When the IHB_ave of the item IHB of the user setting screen is ON (S17), the average value of the IHB value of the area set by the IHBArea of the item IHB of the user setting screen calculated by the image processing circuit 202 is CPU I / F4 (203). Is read via the register IHB_VALU, and the display information is controlled by the graphic circuit 1 (103) and the graphic processing circuit 2 (212) (S18).

  When the level of Pre-Freeze is 0 in the item Freeze Mode on the setting screen, post-freeze processing is performed so that the freeze processing is completed within the freeze time set by the item Freeze (S16).

(Wait of S15 and S16 includes the IHB value average value calculation time and the error of the timer used in Wait in addition to the pre-freeze process.)
On the other hand, when the endoscopic image is frozen (S12), since the FREEZ and OPFRZ bits are originally in an ON state, only the RELSE and OPRLE bits are turned on and latched in synchronization with the vertical synchronization signal VD1, Only the recording instruction signal is transmitted to the freeze circuit 155, the memory 1 (56), the enlargement / enhancement / synchronization circuit 163, the memory 2 (58), the synchronization circuit 208, and the memory 6 (101) (S83). Thereafter, index processing is performed (S19).

FIG. 41 shows a detailed flow of the index process (S19). The bit cpmod of the register Index0 of the CPU I / F 209 of the video + compositing process 93 is set to “00”, and the memory control circuit 312 and the bidirectional buffer 310 are controlled so that the READ and WRITE processes of the memory 8 (112) are not performed ( (If the memory 112 is an SDRAM, the WRITE, READ, WRITEA, and READA commands are not executed. Other commands are executed.)
Also, adisp, odisp, sdisp, tdisp, fdisp, and “0” are set to turn off the display of the index image (see FIGS. 35 to 38) (S32). Wait until a certain time (for example, 1 V when the time between the vertical synchronization signals VD3 is set to 1 V) is waited until S32 is reliably set (S33), and the index image is written (stored) in the memory 8 (112). (S34).

  FIG. 42 shows a detailed flow of the index image WRITE process (S34). The bit cpmod of the register Index0 is set to “10”, and the memory control circuit 312 and the bidirectional buffer 310 are controlled so that the WRITE process of the memory 8 (112) is performed (when the memory 112 is an SDRAM, for example, a WRITE, WRITEA command The endoscope image reduced by the reduction processing circuit 309 is written to the memory 8 (112) (S51).

  Registers wstartv, wstartth, wedv, and wendh (hereinafter referred to as an index WRITE register) of the CPU I / F 209 indicate the range of the endoscopic image to be reduced by the reduction processing circuit 309, and the reduction processing is performed in the designated range. And the WRITE process to the memory 8 (112) is performed (see FIGS. 43 and 44).

The setting value of the index WRITE register varies depending on the type of the endoscope 1, the image size, the screen aspect ratio, and the number of frames of the index image. An example is shown in FIGS.
The reduction ratio of the reduction process is set by bits red2-0 of the register Index0 of the CPU I / F 209 and controls the reduction processing circuit 309, but the setting value differs depending on the type of the endoscope 1, the image size, and the screen aspect ratio. An example is shown in FIGS.

  FIG. 45 shows an example of the memory configuration of the memory 8 (112). In one example, two SDRAMs of 2Mword × 16bit × 4BANK configuration are used so that video data of up to 32 bits per dot can be stored. The video data may be stored in 10 bits each for R, G, and B. A mask signal for masking the index image may be stored in the remaining bits.

  The address in the horizontal direction and the vertical direction indicate the column address and row address of the memory, respectively, and an index image is stored for each bank so that the control can be easily performed. POSITION [0-63] indicates the position of the stored index image. In this embodiment, a maximum of 64 index images can be stored.

  Further, by setting the bit WPOSI (see FIG. 17O) of the register Index1 of the CPU I / F 209, the POSITION to be written in the memory 8 (112) is determined. When an image other than the endoscopic image is displayed, such as a setting screen or a user setting screen (S52), the bit dwmsk = '1' (see FIG. 17N) of the register Index0 of the CPU I / F 209 is set (S54), and the composition is performed. The mask processing of the endoscopic image is turned on by the circuit 308 and a fixed value (for example, ALL “0”) is output to the reduction processing circuit 309, and the reduced image such as the system setting screen or the user setting screen is stored in the memory 8 ( 112) is not written.

  When the endoscopic image is displayed (S52), dwmsk = '0' is set (S53), and the mask processing of the endoscopic image is turned off. In order to reliably write the reduced image for one frame to the memory 8 (112), it waits for a certain time (for example, 3V when the time between the vertical synchronization signals VD3 is 1V) (S55).

  Set the bit cpmod = “00” of the register Index0 of the CPU I / F 209, adisp, odisp, sdisp, tdisp, fdisp, = '0' to turn off the display of the index image (S35 in FIG. 41), and the setting of S35 is ensured. After waiting for a predetermined time (for example, 1 V when the time between the vertical synchronization signals VD3 is 1 V) (S36), index image READ processing is performed (S37).

  FIG. 46 shows a detailed flow of the index image READ process (S37 in FIG. 41). If the Index Delete setting on the setting screen is OFF (S58), the bits cpmod = “01”, adisp = “0”, odisp, sdisp, tdisp, and fdisp of the register Index0 of the CPU I / F 209 are set, and the registers Index3 and Index4 are set. Bits iposi5-0, isposi5-0, itposi5-0, and ifposi5-0 are set to control the memory control circuit 312 and the bidirectional buffer 310 so as to perform the READ processing of the memory 8 (112) (the memory 112 is the SDRAM). In this case, for example, READ and READA commands are executed.) The endoscope image stored in the memory 8 (112) is read, and the mask processing circuit 306 performs index mask processing via the bidirectional buffer 310. After doing The index images are combined by forming processing circuit 313 (S59).

If the Index Delete setting on the setting screen is ON, cpmod is not set at this timing.
The registers rstart, rstart2, rstart3, rstart4, rstartv2, rstartv2, rstartv3, and rstartv4 of the CPU I / F 209 are positions where the reduced image read from the memory 8 (112) is displayed (see FIGS. 43 and 44), and the rareav and rareh are the memory 112. Indicates the range (see FIG. 47) for reading data from each position when the upper left corner of each position is the base point ((x, y) = (0, 0)) (hereinafter referred to as index READ register). Based on the setting, the memory control circuit 312, the bidirectional buffer 310, and the memory 112 are controlled.

  These registers have different setting values depending on the type of the endoscope 1, the image size, the screen aspect ratio, and the number of frames of the index image. An example is shown in FIGS. Further, the registers wmskx0, wmsky0, wmskx1, wmsky1, and wmskt of the CPU I / F 209 are masks of the mask processing circuit 306 when the upper left part of each position of the memory 112 is set as a base point ((x, y) = (0, 0)). A range (see FIG. 47) is shown (hereinafter referred to as an index mask register).

  The register has different set values (that is, mask ranges) depending on the type of endoscope 1 and the screen aspect ratio (an example is shown in FIGS. 22 to 24). However, in the case of the same endoscope 1, control must be performed so that the mask range does not change even if the image size changes. Therefore, in the case of the same endoscope 1, the value of the index mask register is fixed, and the values of the index READ register, the index WRITE register, and the bit red are changed (in this embodiment, for each image size). To the index WRITE register and the bit red).

  In FIG. 41, the bit WPOSI of the register Index1 of the CPU I / F 209 is set, and the position to write to the memory 112 at the next recording instruction is determined. When WPOSI = 63 (S38), WPOSI = 0 is set (S39). Otherwise, the value of WPOSI is incremented (+1) (S40).

  Thereafter, the recording instruction count Z from the start of recording until the recording end instruction (power OFF, inspection end key on the operation device, etc.) is performed is confirmed (S41), and when it is 40 times or more (S42), Caps = Z-40 and Capn = Z-1 (S43) of the register Index2 of the CPU I / F 209, and Caps = 0 and Capn = Z-1 are set when the number is less than 40 (S44), and the index list is displayed. Sets the number of frames displayed for the index image.

  Thereafter, the recording instruction signal ON is sent to the peripheral device (S20 in FIG. 40B) (for example, the RMOSCV0, RMODF0, RMOSCV1, and RMODF1 bits ON of the register REMOTOUTP, VTR — 232C, VTR2 — 232C, DF — 232C, DF2 — 232C, SCV — 232C, SCV2 — 232C (Setting etc.) (Note that the operation of S20 may be controlled to be output during the process of S19).

  After that, the time set by Release Time on the setting screen is waited, and when the HDTV setting time of Release Time ends (S22), the value of IHB_VALU set in S18 is deleted and a blank or a hyphen (-) is displayed. The graphic circuit 212 is controlled (S23), the bits OPFRZ and OPRLE are turned OFF to release the freeze and release, and the RMOSCV1 and RMODF1 bits of the register REMOTOUTP are turned OFF to turn off the recording signal of the peripheral device (S24). .

  Thereafter, when the set time of the SDTV is over (S25), the graphic circuit 103 is controlled to delete the value of IHB_VALU and display a blank or a hyphen (-) (S26), and the bits FREEZ and RELSE are turned OFF. Freeze and release are canceled, and the RMOCV0 and RMOD0 bits of the register REMOTOUTP are turned OFF to turn off the recording signal of the peripheral device (S27).

  When the Release Time HDTV setting time has not ended (S22), and when the SDTV setting time has ended (S80), the graphic circuit is configured to delete the value of IHB_VALU and display a blank or a hyphen (-). 103 (S81), the bits FREEZ and RELSE are turned OFF to release the freeze and release, the RMOSCV0 and RMOD0 bits of the register REMOTOUTP are turned OFF to turn off the recording signal of the peripheral device (S82), and the HDTV is set again. Check the time. Thereafter, index processing 2 is performed (S28).

  FIG. 48 shows a detailed flow of the index process 2 (S28). First, the bits ioposi5-0, isposi5-0, itposi5-0, and ifposi5-0 of the registers Index3 and Index4 of the CPU I / F 209 are incremented by 1 (S201). If any of ioposi5-0, isposi5-0, itposi5-0, and ifposi5-0 = 63 (S205), 0 is set instead of +1 (S206).

  When the Index Delete setting on the setting screen is ON (S202), the bits cpmod = “01”, adisp = “0”, odisp, sdisp, tdisp, and fdisp of the register Index0 of the CPU I / F 209 are set, and the registers Index3 and Index4 are set. Bits iposi5-0, isposi5-0, itposi5-0, and ifposi5-0 are set to control the memory control circuit 312 and the bidirectional buffer 310 so as to perform the READ processing of the memory 8 (112) (the memory 112 is the SDRAM). In this case, for example, READ and READA commands are executed.) The endoscope image stored in the memory 8 (112) is read, and the mask processing circuit 306 performs index mask processing via the bidirectional buffer 310. After doing The index images are combined by forming processing circuit 313 (S203).

  If the Index Delete setting is ON from the settings of S59 and S203, the index image is not displayed during recording to the peripheral device, and as a result, the index image is not displayed on the recorded image. The user can easily add / delete the index image to / from the recorded image by setting ON / OFF of the Index Delete setting.

  FIG. 49 shows the flow of changing the image size. In the figure, first, it is determined whether or not an instruction to change the mask is given (S61). If there is no change instruction, this flow ends. If the change instruction is correct, it is determined whether or not to change the mask size in the enlargement direction (S62). In the case of changing the mask size in the enlargement direction, the image size is switched by changing SIZSEL, HSIZSEL (S63). After waiting for a fixed time (3 V) (S65), HD mask setting is performed (S66). Thereafter, SD mask setting (SMSKSEL) is performed (S68), and this flow ends.

  In the case of changing the mask size in the reduction direction, HD mask setting is performed (S64), SD mask setting (SMSKSEL) is performed (S67), and after waiting for a fixed time (3V) (S69), SIZSEL, HSIZSEL. To change the image size (S70). The reason why the mask processing timing differs between enlargement and reduction is to reduce the influence of noise generated at the edge of the image.

  FIG. 50 shows the flow of the HD mask size setting process of FIG. First, HMKON = '1' (see FIG. 17O) is set (S71), and HMSKX0, HMSKX1, HMSKY0, HMSKY1, HMSKT0, HMSKT1 are set (S72) (HMSKX0, HMSKX1, HMSKY0, HMSKY1, HMSKT0, HMSKT1, 17). Next, HMKON = '0' is set (S73), and this flow ends (S74).

  51 (FIGS. 51A and 51B) is a flowchart showing the recording operation to the printers 306 and 355 among the peripheral devices (the operation when “Capture” is selected in the item “Index record” of the system setting screen). ). The recording operation is performed when the CPU 74 detects that a switch for instructing recording such as a CAPTURE function (for example, the “Print” key on the front panel 69 or the CAP key on the keyboard 14) assigned to the operation device is turned on (S111). ).

  S112 to S119 are performed in the same manner as S12 to S19 in FIG. Thereafter, a recording instruction signal ON is sent to the peripheral device (S120) (for example, setting of a recording instruction command to RMOCVP0, RMOCVP1, CVP_2232C, CVP2_2232C of the register REMOTOUTP).

  Thereafter, when an instruction to end capture is received from the printer 355 (S122), the graphic circuit 212 is controlled so as to delete the value of IHB_VALU set in S118 and display a blank or a hyphen (-) (S123). Then, the bits OPFRZ and OPRLE are turned off to release the freeze and release, and the RMOSCV1 and RMODF1 bits of the register REMOTOUTP are turned off to turn off the recording signal of the peripheral device (S124).

  When a capture end instruction is received from the printer 306 (S125), the graphic circuit 103 is controlled to delete the value of IHB_VALU and display a blank or a hyphen (-) (S126), and the bits FREEZ and RELSE are set. It is turned OFF to release freeze and release, and the RMOCV0 and RMOD0 bits of the register REMOTOUTP are turned OFF to turn off the recording signal of the peripheral device (S127).

  When a capture end instruction is not received from the printer 355 (S122), and when a capture end instruction is received from the printer 306 (S180), the value of IHB_VALU is deleted and a blank or a hyphen (-) is displayed. The graphic circuit 103 is controlled (S181), the bits FREEZ and RELSE are turned OFF to release the freeze and release, the RMOCV0 and RMOD0 bits of the register REMOTOUTP are turned OFF to turn off the recording signal of the peripheral device (S182), and the printer again. From 355, the capture end instruction is confirmed.

  The capture end confirmation in S122, S125, and S180 is performed only for a certain period, and if the process is not completed within the certain period, an error process is performed with a timeout (error display to peripheral device, error command transmission, etc.) End the recording operation.

(The capture end instruction is, for example, that the RMICVP1 and RMICVP0 bits of the register REMOTINP are OK or the capture completion command is received at CVP — 232C, CVP2 — 232C).
As shown in FIG. 51, in the recording operation to the printers 306 and 355, if there is a recording operation at the time of freezing (Yes in S112), the FREEZ and OPFRZ in S124 and S182 are kept ON and the freeze is released. It may be possible not to perform the operation, or the operation that does not cancel / cancel the freeze may be automatically changed depending on the language (destination) set in the item “Language” on the system setting screen (for example, “JP” selection) (Freeze is not canceled at the time, and freeze is canceled when “US”, “GB”, “FR”, “D” is selected).

  In S128, the same processing as S28 is performed. The recording instruction count Z is counted independently in the case of the recording operation to the photography devices 307 and 356 and the filing devices 308 and 357 (S19) and in the case of the recording operation to the printers 306 and 355 (S119). The sum of the coefficients of S19 and S119 may also be used.

  FIG. 52 shows the relationship among the memory 8 (112), the register Index0, and the endoscope composite image. 40 and 51, when a recording error command (including a capture error and during printer printing) is received from the recording device during the processing of S20, S120, S122, S125, and S180, index processing based on the recording operation is performed. It is also possible to invalidate and not update the index image.

  Further, when Release + Capture is selected in the item “Index record” on the system setting screen, the common processing of the recording processing of FIGS. 40 and 51 may be performed in common, and the program may be saved. .

  FIG. 53 (FIGS. 53A and 53B) shows a flowchart of the index list display operation. When the image list display SW is input from the operation device (for example, “SHIFT + SEACH” in FIG. 69C) (S210), when the endoscope screen is being displayed (S211), the register HCNTL of the CPU I / F 209 is displayed. The bit HCHRON of the CPU is set to “0”, the graphic circuits 103 and 212 are controlled to erase characters and graphics such as endoscope related information, and the bit HMUTE of the register HCNTL of the CPU I / F 209 is set to “0”. Thus, the display of the endoscopic image is turned off, the bit cpmod = “00”, adisp, odisp, sdisp, tdisp, fdisp = “0” of the register Index0 of the CPU I / F 209 is set to turn off the display of the index image (S212). ), A certain period of time until the setting of S212 is surely performed ( In example 1V minute when the time between the vertical synchronizing signal VD3 as 1V) to Wait (S213).

  Then, registers rstart, rstart2, rstart3, rstartth4, rstart5, rstartv, rstartv2, rstartv3, rstartv4, rareav, rareah, wmskx0, wmsky0, wmskyx1, wmsky1, wmskt1 are set (see FIG. 54).

(Setting values differ depending on the type of endoscope 1, image size, and screen aspect ratio) (an example is shown in FIG. 25).
Further, the bit capp of the register Index2 of the CPU I / F 209 is set to “00” so that the first page of the index list display is displayed (S218). Wait until the setting of S218 is surely performed (for example, 1 V when the time between the vertical synchronizing signals VD3 is 1 V) (S219), and the CPU interface 209 register Index0 bit cpmod = "01", adisp = '1' is set (S220), and an index list is displayed (S221).

  When the index list display screen is displayed when the image list display SW is input (S211), the bit cpmod = “00”, adisp, odisp, sdisp, CPUI / F209 register Index0 is displayed. tdisp, fdisp = '0', the index image display is turned OFF (S214), and a fixed time until the setting of S214 is performed reliably (for example, 1V when the time between the vertical synchronization signals VD3 is 1V) Wait (S215), set the bit HCHRON of the register HCNTL of the CPU I / F 209 to “1”, control the graphic circuits 103 and 212 to display characters and graphics such as endoscope related information, and the register of the CPU I / F 209 Endoscope with HCNTL bit HMUTE set to '1' ON the display of the image, CPU I / F 209 of the bits of the register Index0 cpmod, back adisp, odisp, sdisp, tdisp, fdisp, caps, the state of the endoscopic image displayed during the previous index list capn (S216).

  FIG. 52 shows the relationship between the register Index0 and the endoscope composite image. It is possible to perform a recording operation such as the release or capture operation described above when displaying the index list. In that case, only one of the release and capture may be enabled.

  FIG. 55 (FIGS. 55A and 55B) shows a flowchart of the page switching operation of the index list display. When the PAGE switching SW is input from the operation device (S225), the index image is displayed by setting the bits cpmod = “00”, adisp, odisp, sdisp, tdisp, fdisp = “0” of the register Index0 of the CPU I / F 209. Is turned off (S226), and a certain time (for example, 1V when the time between the vertical synchronization signals VD3 is 1V) is waited until the setting of S226 is surely performed (S227).

  If the bit capp = of the register Index2 of the CPU I / F 209 is “00” (S228), capp = “01” is set, and the second page of the index list display is set to be displayed (S229). For example, if the number of index images displayed on one page is 20, control is performed so as not to move to the second page when the number of recording instructions Z ≦ 20 (error processing (error sound or error display) is performed). May be).

  On the second page, when Z <40, the number of Z-20 is displayed. If Z ≧ 40, Caps = Z-40 and Capn = Z-1 are set in S43, and the latest 20 written data are displayed in the memory 112. If the bit capp = of the register Index2 of the CPU I / F 209 is “01” (S228), capp = “00” is set so that the first page of the index list display is displayed (S230).

  If Z ≧ 40, Caps = Z-40 and Capn = Z-1 are set in S43, so the next 20 of the 20 most recent images displayed on the second page are the first page. It is displayed (S230). Wait until the setting of S229 or S230 is performed reliably (for example, 1 V when the time between the vertical synchronization signals VD3 is 1 V) (S231), and the bit cpmod = “01” of the register Index0 of the CPU I / F 209 ", Adsp = '1', and the index image is displayed again (S232).

  56 and 57 show an example of the index list (the numbers in the index image indicate the value of Z). FIG. 56 shows only one page when Z = 15. FIG. 57 shows the case of Z = 42, FIG. 57 (a) shows the first page, and FIG. 57 (b) shows the second page. Since Z = 42 ≧ 40, the latest 40 images are displayed.

FIG. 58 is a flowchart showing a series of operations for continuously creating index images. The power of the processor 13 is turned on (S240), the program mode is determined (S400) (refer to the flowchart of FIG. 85 for details), and each circuit in the processor is initialized (S241). (If the endoscope 1 is replaced while the power of the processor 13 is ON, S400 is omitted, S401)
In S241, a part of the CPU I / F (209) of the video + compositing processing circuit 93 is initialized as follows.

その後、映像処理回路１（５５）のＣＰＵＩ／Ｆ１５のレジスタＣＣＤに格納された内視鏡１又はＣＣＤ２の種類の情報をＣＰＵ７４がＲＥＡＤし、内視鏡１又はＣＣＤ２の種別を行う（Ｓ２４２）。ＢＡＣＫＵＰ ＲＡＭ７７には、操作デバイス（フロントパネル６９、キーボード１４他）の設定や、プロセッサ１３のプログラムのバージョン、設定画面、ユーザー設定画面で設定された各設定項目が全て格納されており、プロセッサ３の電源ＯＦＦ時にも保存されている。

Thereafter, the CPU 74 reads the type information of the endoscope 1 or CCD 2 stored in the register CCD of the CPU I / F 15 of the video processing circuit 1 (55), and performs the type of the endoscope 1 or CCD 2 (S242). The BACKUP RAM 77 stores all the setting items set on the operation device (front panel 69, keyboard 14, etc.), the program version of the processor 13, the setting screen, and the user setting screen. It is saved even when the power is turned off.

  Image Size information on the user setting screen is also stored, and when the power of the processor 3 is turned on or the endoscope 1 is replaced, one of the Image Sizes (for example, fixed to the left side) is set in S241 (ImageSize is Medium ← (If the Full setting has been saved, set the Medium on the left).

  In S243, one side of the ImageSize set in S241 is determined. Thereafter, the setting of the bit red, the index WRITE register, the index READ register, and the index mask register of the register Index0 is performed from the setting of the type of the endoscope 1 or the CCD 2, the ImageSize, and the item “HDTV: Mon Size” on the setting screen. S244). (See FIGS. 20 to 24 for setting examples). Thereafter, the normal processing is started (S245).

The image size is set to one (for example, fixed to the left side) in the following cases.
-When a RESET process is performed by pressing the RESET switch 400 on the front panel (69),
When the ImageSize Change is Determined on the User Setting Screen FIG. 59 is a flowchart showing a part of the normal processing in S245. When the recording SW is input from the operation device and the CPU 74 detects that the recording SW is ON (S246), the recording operation and index creation shown in FIGS. 40 and 51 are repeated every time the recording SW is detected (S247). 26 to 29 show changes in the display state of the endoscope screen during the operations of S246 and S247. The change state of the register setting at that time is as follows.

なお、システム設定画面の項目ＨＤＴＶのＭｏｎ Ｓｉｚｅで異なるアスペクト比が選択、設定完了した直後（例えば、４：３→５：４や５：４→１６：９に変更された場合）は、レジスタは以下のように設定し、内視鏡合成画像下のインデックス４駒、１駒及びインデックス一覧のインデックスの表示は消去する。

In the system setting screen item HDTV Mon Size, different aspect ratios are selected and set immediately (for example, when changed to 4: 3 → 5: 4 or 5: 4 → 16: 9), The following settings are made, and the display of the index 4 frames, 1 frame, and the index list under the endoscope composite image is deleted.

また、操作デバイス（例えばキーボードの５００）にある検査終了キーを押した場合には、レジスタは以下のように設定され、インデックス４駒、１駒は消去されるが、インデックス表示は表示されるようにし、

When an examination end key on the operation device (for example, the keyboard 500) is pressed, the registers are set as follows, and the index 4 frames and 1 frame are erased, but the index display is displayed. West,

その後の最初のレリーズ処理時に、インデックス表示レジスタを設定し直すようにする。これより、検査終了キーが押された後でも、インデックス画像の確認を行うことができる。

Then, the index display register is reset during the first release process. Thus, even after the inspection end key is pressed, the index image can be confirmed.

また、操作デバイスに割り当てられた画像サイズキーにより、画像サイズ変更操作が入力された場合は（Ｓ２４８）、設定画面で設定された画像サイズに変更する（Ｓ２４９）。その際、内視鏡画像がインデックス画像と重なる場合には（Ｓ２５０）、設定されているレジスタ値の内ａｄｉｓｐ，ｏｄｉｓｐ，ｓｄｉｓｐ，ｔｄｉｓｐ，ｆｄｉｓｐを退避し（Ｓ２５１）、ａｄｉｓｐ，ｏｄｉｓｐ，ｓｄｉｓｐ，ｔｄｉｓｐ，ｆｄｉｓｐ＝‘０’に設定することでインデックス画像を消去する（Ｓ２５２）。

If an image size change operation is input using the image size key assigned to the operation device (S248), the image size is changed to the image size set on the setting screen (S249). At this time, if the endoscopic image overlaps with the index image (S250), the set register values adisp, odisp, sdisp, tdisp, and fdisp are saved (S251), and the adisp, odisp, sdisp, tdisp , Fdisp = '0', the index image is deleted (S252).

Thereafter, the Red, index WRITE register, index Read register, and index mask register are set (S253). (Note that the following FIGS. 60 to 62 are not limited to S253, but are flows performed when all index registers are set.)
FIG. 60 shows a processing flow of register setting for WRITE. First, WPON = '1' is set (S261), and wstartv, wstartth, wendv, and wendh are set (S262) (refer to FIG. 17 for wstartv, wstartth, wendv, and wendh). Next, WPON = '0' is set (S263), and this flow ends (S264).

  FIG. 61 shows a processing flow for setting the READ register. First, RPON = '1' is set (S271), and rstartth, rstartth2, rstartth3, rstartth4, rstartv, rstartv2, rstartv3, rstartv4, rareav, rarealh are set (S272) (rstartth, rstartth2, rstartv3, rstartv3, rstartv3, rstartv3, rstartv3, rstartv3 (See FIG. 17 for rstartv3, rstartv4, rareav, and rareah). Next, RPON = “0” is set (S273), and this flow ends (S274).

  FIG. 62 shows a processing flow for setting the index mask register. First, WMSKON = '1' is set (S281), and wmskx0, wmsky0, wmskx1, wmsky1, and wmskt are set (S282) (see FIG. 17 for wstartv, wstartth, wendv, and wendh). Next, WMSKON = '0' is set (S283), and this flow ends (S284).

FIG. 63 shows an example of index image erasure when the endoscope images overlap when the screen aspect ratio is 4: 3, 5: 4 and the index is 4 frames.
On the other hand, if the endoscope image does not overlap with the index when the image size is changed, if the set value is saved (S254), the set adisp, odisp, sdisp, tdisp, and fdisp are returned (S255). .

If the endoscopic image overlaps with some endoscope related information (S256), the display of the information is deleted (S257).
FIG. 64 shows an example of part of the endoscope-related information erasure when the endoscope images overlap when the screen aspect ratio is 4: 3, 5: 4 and the index is one frame.

If they do not overlap, the display state is set (S258).
(Some endoscope-related information includes information read from the memory 8 in the endoscope 1).

  As a result, when the image size of the endoscopic image is changed and the endoscopic image overlaps with the index image or endoscope related information, the index image or endoscope related information is deleted. It is possible to prevent adverse effects on examinations and operations due to overlapping.

  Note that the values of adisp, odisp, sdisp, tdisp, and fdisp set at the time of index creation in S247 are updated with respect to the saved values when saved in S251.

In S250 and S256, it is determined whether or not the index image or the endoscope related information overlaps.
-It calculates | requires by calculation from the coordinate of an endoscopic image, and the coordinate of an index image or endoscope related information.

    The following table may be prepared based on the type of the endoscope 1 (or the CCD 2), the image size, and the screen aspect ratio.

前記の内視鏡合成画像の記録時のフロー及びインデックス処理により、
・内視鏡１（又はＣＣＤ２）の種類によって、内視鏡画像に合わせて、インデックス画像が最適なサイズ、位置になるように制御でき、使用者が観察しやすい画像を提供できる。

By the flow and index processing at the time of recording the endoscope composite image,
Depending on the type of the endoscope 1 (or the CCD 2), the index image can be controlled to have an optimal size and position according to the endoscope image, and an image that can be easily observed by the user can be provided.

-According to the image size of the endoscopic image, the index image can be controlled so as to have an optimal size and position, and an image that can be easily observed by the user can be provided.
In the same endoscope 1 (CCD2), it is possible to control the index image to be the same even if the image size is changed, and even if the image size is changed, the endoscope image is not uncomfortable to the user. And index images can be observed.

    -When the endoscopic image overlaps with the index image, the index image is deleted, and the overlapping of the images does not make it difficult for the user to observe the endoscopic image, thereby improving the efficiency of examination, examination, and surgery. Can be planned.

    ・ When the endoscope image overlaps with the endoscope related information, the endoscope related information is erased, and the overlap with the image does not make it difficult for the user to observe the endoscope image. The efficiency of examination and surgery can be improved. The endoscope related information includes information read from the memory 8 in the endoscope 1.

    By changing the setting item of the system setting screen item “Index Delete”, it is possible to control the display or non-display of an index image during recording during a recording operation such as release or capture. Thus, it is possible to deal with users who need an index for recorded images and users who do not need an index image, and can provide an easy-to-use endoscope apparatus or endoscope system.

    D. of setting item Remote Control in Table 4A. In F, for example, when “TYPEB” is selected, the setting item of “Index Delete” may be automatically switched to ON. Thus, display control of the index image can be performed according to the connected peripheral device.

    The setting of “Index Delete” may be changeable through filing devices 308 and 357, photography devices 307 and 356, recording devices 86 and 87, and a serial interface or parallel interface via SIO 250 or PIO 251. As a result, the display control of the index image can be controlled from the peripheral device (Note that not only the index but also all the endoscope related information, setting of various setting screens, and reading and changing the setting state of the operation device are ( Including disabling operation keys), and by peripheral devices.)

    As shown in FIG. 8, only specific graphic data (for example, an arrow cursor) can be combined with an index image. Therefore, when an index image is generated, endoscope related items other than the arrow cursor (for example, 624, 624 ′) Information (for example, 600 to 623, 600 ′ to 623 ′, error messages, messages in FIGS. 75 and 76 to 80, etc.) is not included in the index image even if it overlaps the endoscopic image (not synthesized). It is possible to provide an index image that is easy to observe for the user.

    -The index image may be displayed only in the endoscope composite image output in the composition process 2 (99) by creating only the video + composition process 93, and the composition processing circuit 102 also generates the index image. Thus, the image may also be output to the composition process 1 (61) and the endoscope composite image of the digital encoder 62.

  FIG. 65 shows a connection example of peripheral devices when the processor 13, the keyboard 2 (45), and the ultrasonic device 358 are combined. The keyboard 2 (45) is connected to each of the ultrasonic apparatus 358 and the processor 13 through a serial interface, and can control each operation.

  The processor 13 controls the monitor 353 via the SIO 250 or the PIO 251 each time the switch for switching the video output of the ultrasonic device 358 of the keyboard 2 (45) and the output of the processor 13 is pressed. The video output 360 of the ultrasonic device 358 is switched (toggle operation).

When the stopwatch key is pressed in the state of FIG. 70-1 (a), the stopwatch is displayed in an empty area on the left side of the screen, and the stopwatch starts (FIG. 70-1 (b)). Further, when the stopwatch key is pressed, the stopwatch is temporarily stopped (FIG. 70-2 (c)).

  If the stopwatch key is pressed while pressing the shift key in the state of FIG. 70-2 (c), the stopwatch is restarted (FIG. 70-3 (e)), and if the stopwatch key is pressed, the stopwatch is paused again ( FIG. 70-3 (c)). When the stopwatch key is pressed in the state of FIG. 70-2 (c), the stopwatch is terminated and the display of the stopwatch disappears from the screen (FIG. 70-2 (d)).

  FIG. 71 shows a stopwatch with an endoscopic image controlled by the video processing 2 (57) output in the SDTV. When the stopwatch key is pressed in the state of FIG. 71 (a), the time display on the left of the screen is switched to the stopwatch display, and the stopwatch starts (FIG. 71b). Further, when the stopwatch key is pressed, the stopwatch is temporarily stopped (FIG. 71 (c)).

  If the stopwatch key is pressed while pressing the shift key in the state of FIG. 71 (c), the stopwatch restarts (FIG. 71 (e)), and if the stopwatch key is pressed, the stopwatch is paused again (FIG. 71 (c) )). When the stopwatch key is pressed in the state of FIG. 71 (c), the stopwatch is terminated and the stopwatch display is switched to the time display (FIG. 71 (d)). 70 and 71 may be operated by the same stopwatch key.

  72 (FIGS. 72-1 and 72-2) shows REMOVE DATA in an endoscopic image controlled by video + compositing processing (93) output in HDTV. The figure shows how the endoscope related information displayed on the screen is erased step by step each time the REMOVE DATA key is pressed. Endoscope related information will be described with reference to FIG.

  FIG. 72-1 (a) shows a state in which all the endoscope related information is displayed. When the REMOVE DATA key is pressed, a part of the endoscope related information is deleted (FIG. 72-1 (b). ) Abbreviated display 1). When the REMOVE DATA key is further pressed, a part of the endoscope related information is further deleted (FIG. 72-2 (c) omitted display 2). When the REMOVE DATA key is further pressed, all the endoscope related information displayed on the screen is deleted (FIG. 72-2 (d) all deletion).

FIG. 73 (c-1) shows an abbreviated display 2 during the stopwatch operation. When the REMOVE DATA key is further pressed, all the endoscope related information displayed on the screen is deleted (FIG. 73 (d) all deletion).

FIG. 74 (FIGS. 74A, 74B, and 74C) shows an example of endoscope related information (part) displayed on the endoscope composite image display screen in the present embodiment.
FIG. 75 shows an example in which a part of the endoscope related information is displayed for a certain period. In the figure, for example, a part of the endoscope related information that is not normally displayed is displayed in an overlay on the index image display area by the key operation of the operation device (for example, SCOPE INFO (504) in FIG. 69F). In this way, it is possible to easily refer to predetermined endoscope related information with a low display frequency.

  Further, as described above, in FIGS. 72 and 73, the display of the endoscope related information can be controlled by a dedicated display control switch (for example, the REMOVE DATA key 528 of the keyboard 14). (Including information stored in the memory 8 in the endoscope 1).

  Also, the endoscope related information to be combined in the video + compositing processing 93 and the endoscope related information to be combined in the combining processing circuit 102 can be displayed separately (for example, only the video + compositing processing 93 is always displayed for 619 to 621). Yes.) The display contents of endoscope related information can be controlled (selection of display or non-display) according to the image quality and display range of multiple image outputs. Output can be selected.

  Next, a description will be given of displaying on the screen a message indicating that a predetermined process is being performed and whether a predetermined setting has been made. In particular, it is detected whether or not white balance processing is set, and a message to that effect is displayed on the screen. An example is shown below. Note that “WB” described below is an abbreviation for white balance.

  FIG. 76 shows an example of a message display indicating that the index list is being displayed. In the figure, a message “Index Display” indicating that the index list is being displayed is displayed (this display is only displayed for the synthesis processing circuit 102 in which the index is not synthesized, so that the index list is displayed to the user. To inform you of that).

  FIG. 77 shows a message display notifying that the white balance processing is not set. In the figure, since the white balance process is not set, a message “Please Adjust WB” prompting the user to set the white balance process is displayed.

  FIG. 78 shows an example of a message for notifying that the white balance processing setting is completed. In the figure, a message “WB Adjustment is completed” indicating that the white balance processing setting is completed is displayed.

  FIG. 79 shows an example of a message notifying that the white balance processing setting has failed. In the figure, “WB Adjustment error” indicating that the white balance processing setting has failed is displayed.

FIG. 80 shows an example of a message displaying the program version of the endoscope 1 and the light source 17 and the communication result.
These will be described in detail below.

  81 (FIGS. 81A and 81B) and FIG. 82 are flowcharts showing the operation of white balance processing. FIG. 81 is a flowchart showing a portion related to the white balance process in the initialization process of the flow of FIG. 58 (S241 of FIG. 58). The CPU 74 detects the signal level 29 b via the PIO 251 of the control circuit 67 and identifies the type of light source connected to the processor 13.

  When the signal level is “Hi”, it is determined that the light source 17a does not have a communication function (see FIG. 1B) (S301), and the white balance data stored in the BACKUP RAM 77 is used. White balance processing is performed by the W / B circuit 153 (S315). When the LED “INC.” Above the white balance switch (404) of the front panel 69 is turned on and the WB Message item “ON” is set in the system setting screen, the “Plause Adjust WB” is displayed on the endoscope composite image display screen. Is displayed, indicating that white balance processing has not been set (S316).

  It should be noted that “please adjust WB” is displayed until the white balance switch (404) on the front panel 69 is input, the white balance processing is completed, and a white balance completion message (“WB adjustment is completed!”) Is displayed. Continue to display. When the signal level is “Low”, it is determined that the light source 17 has a communication function (S301), and DSR is detected among the signal lines of the serial interface via the SIO 250.

  When the power source of the light source 17 is ON, the DSR is turned ON on the light source side. When it is determined that the DSR is ON, communication processing with the light source 17 is started (S302). First, the serial number of the light source 17 stored in the memory 23 of the light source 17 is read (S303), and the memory 8 in the endoscope 1 is searched for white balance data corresponding to the serial number, If there is corresponding white balance data, the white balance data is read.

  If not, a command indicating that there is no white balance data is read (S306). If there is corresponding white balance data (S321), coefficient values such as G / R, G / B, etc. are obtained from the read white balance data, and the W / B circuit 153 in the video processing 1 automatically The white balance processing is performed (S308), the LED “COMP.” Above the white balance switch (404) of the front panel 69 is turned on to indicate that the white balance processing has been set (S309), The message “WB Adjustment is completed!” To the endoscope composite image display screen is not displayed), and the white balance data is stored in the BACKUP RAM 77 (S310).

  Thereafter, other light source information (software and hardware versions, failure status, etc.) stored in the memory 23 of the light source 17 is also read (S311). The white balance data to be read is the average value of R, G, B for each of a plurality of horizontal (or vertical) line signals read from the CCD 2, or G / R, B for each of a plurality of horizontal (or vertical) line signals. It may be a coefficient value of / R.

In the case of the average value of R, G, and B for each of a plurality of horizontal (or vertical) line signals read from the CCD 2, in order to reduce the amount of data stored in the memory 8, the R, G of one of the plurality of horizontal line signals is stored. , The B average value and only the G average value of other horizontal lines may be stored, and processing may be performed so as to obtain all the G / R and B / R coefficient values by performing the calculation in S308. (In the white balance process (8) of the W / B circuit 153, which will be described later, the thick frame data in Table 21)
If there is no corresponding white balance data (S321), white balance processing is performed by the W / B circuit 153 in the video processing 1 using the white balance data stored in the BACKUP RAM 77 (S319). When the LED “INC.” Above the white balance switch (404) of the front panel 69 is turned on and the WB Message item “ON” is set in the system setting screen, the “Plause Adjust WB” is displayed on the endoscope composite image display screen. Is displayed, indicating that white balance processing has not been set (S320).

  When DSR is off, the power of the light source is OFF, so communication processing with the light source 17 is not performed (S302), and the white balance data stored in the BACKUP RAM 77 is used to The white balance processing is performed by the / B circuit 153 (S319).

  When the LED “INC.” Above the white balance switch (404) of the front panel 69 is turned on and the WB Message item “ON” is set in the system setting screen, the “Plause Adjust WB” is displayed on the endoscope composite image display screen. Is displayed, indicating that white balance processing has not been set (S320).

  After S311, the other endoscope related information in the memory 8 in the endoscope 1 is read. When performing communication processing to the light source 17 and the endoscope 1, it is determined whether the communication has been normally received (S305, S307, S322). If the communication has not been normally received, retry processing is performed (S304, S313). , S323).

  The number of retries is changed according to the communication device and communication timing (one or more times). If it cannot be received normally even after the set number of retries, it will end abnormally as a communication error. If the process ends abnormally in S304 and S313, white balance processing is performed by the W / B circuit 153 in the video processing 1 using the white balance data stored in the BACKUP RAM 77 (S315, S319).

  When the LED “INC.” Above the white balance switch (404) of the front panel 69 is turned on and the WB Message item “ON” is set in the system setting screen, the “Plause Adjust WB” is displayed on the endoscope composite image display screen. Is displayed, indicating that white balance processing has not been set (S316, S320).

  FIG. 82 is a flowchart of white balance processing when the processor is turned on and normal processing is being performed (S245 in FIG. 58), the light source is turned on, and the communication line DSR is turned on. . The figure shows the operation when the WB key is pressed. The DSR ON interrupt may be a level interrupt or a trigger interrupt.

  When interrupted (S330), communication processing with the light source 17 is started (S331). First, the serial number of the light source 17 stored in the memory 23 of the light source 17 is read (S331), and the memory 8 in the endoscope 1 is searched for white balance data corresponding to the serial number, If there is corresponding white balance data, the white balance data is read.

If there is no corresponding white balance data, a command indicating that there is no white balance data is read (S334). If there is corresponding white balance data (S348), the G / R and G / B coefficient values are obtained from the read white balance data, and automatically obtained by the W / B circuit 153 in the video processing 1. White balance processing is performed (S336), and the LED “COMP.” Above the white balance switch (404) of the front panel 69 is turned on to indicate that the white balance processing has been set (S337). (The message “WB Adjustment is completed!” To the endoscope composite image display screen is not displayed.)
At this time, if “Please Adjust WB” is displayed in the endoscope observation image (endoscope composite image display screen), the display is automatically deleted. Further, the white balance data is stored in the BACKUP RAM 77 (S338). Thereafter, other light source information (software and hardware versions, failure status, etc.) stored in the memory 23 of the light source 17 is also read (S339).

  If there is no corresponding white balance data (S348), white balance processing is performed by the W / B circuit 153 in the video processing 1 using the white balance data stored in the BACKUP RAM 77 (S344).

  When the LED “INC.” Above the white balance switch (404) of the front panel 69 is turned on and the WB Message item “ON” is set in the system setting screen, the “Plause Adjust WB” is displayed on the endoscope composite image display screen. Is displayed, indicating that white balance processing has not been set (S345). In addition, when performing communication processing to the light source 17 and the endoscope 1, it is determined whether the communication is normally received (S333, S335, S346). If the communication is not normally received, retry processing is performed (S332, S341). , S347).

  The number of retries is changed according to the communication device and communication timing (one or more times). If it cannot be received normally even after the set number of retries, it will end abnormally as a communication error. If the process ends abnormally in S332 and S341, white balance processing is performed by the W / B circuit 153 in the video processing 1 using the white balance data stored in the BACKUP RAM 77 (S342 and S344).

  When the LED “INC.” Above the white balance switch (404) of the front panel 69 is turned on and the WB Message item “ON” is set in the system setting screen, the “Plause Adjust WB” is displayed on the endoscope composite image display screen. Is displayed, indicating that white balance processing has not been set (S343, S345).

  If the endoscope 1 is not connected to the processor 13, “Please Adjust WB” is not displayed on the endoscope composite image display screen. There is also an endoscope that does not have a communication function with the processor 13. In that case, the flow is S307, S313, S315,. When the white balance switch (404) of the front panel 69 is pressed when the signal level of the signal line 29b is LOW and DSR = OFF, it is determined that the power source of the light source 17 is OFF, and an error buzzer is generated by the buzzer 71. An instruction is given to turn on the power of the light source 17 by sounding a sound (for example, a short continuous sound of medium sound) or by displaying an error message on the endoscope composite image display screen.

  When the signal level of the signal line 29b is HI, an error buzzer sound by the buzzer 71 (for example, a continuous sound with a short middle tone) and an error message are not performed on the endoscope composite image display screen.

  Next, details of white balance processing of the W / B circuit 153 in the video processing 1 (55) when the WB switch of the operation device (for example, WHITE BAL. (404) on the front panel 69) is pressed will be described. . The procedure is as follows (performed when a white index is imaged on the CCD 2 of the endoscope 1 and the RGB input signals are at the same signal level).

(4) Set “0” to WH_ON of WHT_ON. (5) WAIT (Ex, vertical synchronization signal VD1 is 3V WAIT (Because of frame sequential type, wait until the average value of R, G, B is updated))
(6) Repeat (2) to (4) above.

(11) The average value of R, G, B signals and correction coefficient data are stored in the BACKUP RAM 77.

(12) The data of the thick frame in (8) is stored in the memory 8 of the endoscope 1. At that time, the data is stored in association with the serial number of the light source 17 connected to the processor 13.
81 and 82, the white balance data to be read from the memory 8 in the endoscope 1 in S306 and S334 is the thick frame in (8) described above in order to reduce the data to be stored. Data is read and a correction coefficient obtained by calculation is set in the WB circuit 153.

  If the calculated correction coefficient data overflows, the “INC” LED above the white balance switch blinks for 5 seconds, and then the “INC” LED lights. At this time, an error sound (a sound of the buzzer 71 (for example, a short high tone is repeated for a certain period)) is sounded. Further, “WB Adjustment error!” Is displayed for a certain period (Ex. 5 seconds) on the endoscope composite image display screen.

The average value of white balance and the white balance coefficient are displayed as shown in the item “WB” in FIG. 14 (FIG. 14: The average value of white balance is the value of the thick frame in (8) above. )
By the white balance process,
The white balance setting state can be displayed on an operation device (for example, INC and COMP LEDs on the top of WHITE BAL. (404) on the front panel 69) or an endoscope composite image (FIGS. 77 to 79). In addition, since it is possible to notify with a sound by the buzzer 71, even if the user forgets to take the white balance, it can be easily and instantly noticed, and there is no trouble in the examination and the operation.

    -In addition, since white balance can be controlled corresponding to a plurality of light sources (17, 17a), processors can be combined regardless of the type of light source, and the range of user equipment selection is widened and used. An easy-to-use endoscope device and endoscope system can be provided.

    When the light source 17 is turned off, the user can turn on the light source 17 by displaying an error on the endoscope composite image or notifying the buzzer 71 with sound during white balance processing. Can be instructed and the white balance processing can be performed correctly, so that an optimal endoscopic image can be provided to the user.

FIG. 83 shows another embodiment of the screen display method when the screen aspect ratio is 16: 9.
-Display the function of the operation device on the left and right (or either) of the observation image (endoscope composite image display screen), and use the cursor key and enter key on the operation device to The function can be performed even on the endoscope composite image display screen).

-Display of items set on the system setting screen and user setting screen-The program version of the processor 13, the light source 17, and the endoscope 1 can be displayed. The display content may be arbitrarily selected by the user. It should be noted that at the place where the index image and the endoscope related information overlap (399), the index image may be prioritized and the endoscope related information may be displayed so as to be hidden, and it is selected on the operation device which is prioritized. A key may be provided, and selection items may be prepared on a user setting screen or the like.

  FIG. 84 shows a version upgrade example of the program, FPGA data, and parameters of the processor 13. Using a cable or connector of a peripheral device (for example, a filing device) to which the processor 13 is connected, a VerUP device 450 such as a personal computer is connected, and the version is upgraded using a serial interface via the SIO 250.

  The processor software is started in the VerUP mode by turning on the power of the processor 13 while simultaneously pressing specific keys of the operation device (for example, simultaneously pressing one or more specific keys on the front panel 69) (see FIG. 85).

VerUP, READ, WRITE, Verify, and update of the following data can be performed from the software on the VerUP device 450.
-Program of processor 13 stored in program ROM 83-Configuration data stored in each configuration memory-Parameters stored in parameter memory-Setting data stored in BACKUPRAM-Physical address of ETHERNET Configuration data, When upgrading parameter data,
(1) The configuration IC is selected by the bits BNK3-0 of the register BANKSL in the address decoder 80, and then the configuration data is set. (2) The bit CMON of the register MEMOK of the selected configuration IC is set to “1”. (3) This is performed in the procedure of writing to the configuration memory connected to the selected configuration IC (see FIG. 17R for the registers).

  The program ROM 83, each configuration memory, and each parameter memory may be EEPROM, FLASH ROM, FRAM, FeRAM, MRAM, OUM, battery-equipped SRAM, and may be either a parallel interface or a serial interface.

  When the processor power is turned on again after upgrading the program of the processor 13, the version information of the new program stored in the program ROM 83 is compared with the version of the program stored in the BACKUPRAM 77 before the upgrade. If they are different, the setting of the operation device (front panel 69, keyboard 14, etc.), each setting item set on the setting screen and user setting screen is automatically set to the factory default value, and the malfunction of the program by VerUP May be avoided.

FIG. 85 is a flowchart showing details of the program mode discrimination (S400). When the processor 13 is powered on, the bits CMSL and CON of the register MEMOK of the CPU I / F of each configuration IC are preset to “0”, so that the FPGA of each block is a configuration memory for VerUP in each configuration memory Configuration is automatically performed using the area (address area H'09C00000 to H'09FFFFFF) (S402). (Read / Write can be set in the register (MEMOK) of each configuration IC by setting the register BANKSL in FIG. 17R.)
After the configuration is normally completed (S403), if simultaneous pressing of a specific key of the operating device (for example, simultaneous pressing of one or more specific keys on the front panel 69) is detected, the program of the processor 13 is updated to VerUP. The operation is performed in the mode (S404, S403). The confirmation method of whether or not the configuration of S403 is normally completed is to confirm the completion of the configuration of all the FPGAs.
(1) Select configuration IC with bits BNK3-0 of register BANKSL in address decoder 80 (2) Check bit COK = '1' in register MEMOK of selected configuration IC (3) Check with all configuration ICs Follow the confirmation procedure. By confirming whether the configuration is normally completed in S403, for example, it is possible to confirm whether the SIO 250 and PIO 251 operating on the control circuit 67 are operable, and thus it is possible to detect the operation device. From S402, when the program of the processor 13 operates in the VerUP mode, the configuration is performed in the VerUP configuration memory.

  Therefore, even if the configuration data version upgrade fails in the VerUP mode and incorrect data is stored in the normal configuration memory, in the VerUP mode, the configuration data is configured with the correct data stored in the VerUP configuration memory. Therefore, the normal operation of each FPGA can be confirmed in the VerUP mode.

(For example, if VerUP of the configuration data in the normal use of the configuration memory 4 fails, the configuration using the configuration data in the normal use is not normally completed in the next configuration, and the control circuit 67 SIO 250 does not operate, so version upgrade cannot be performed via SIO 250. However, since the configuration data for Verup is used in the Verup mode, the version is again transmitted via SIO 250 in control circuit 67. It becomes possible to perform up.)
On the other hand, if there is no input of a specific key from the operation device, it is determined that it is normally used (S404), CON of register MEMOK of each configuration IC is set to '1', and the configuration processing is turned off. (S406) After setting to enable configuration using the normal configuration memory area (address areas H'098000000 to H'09BFFFFF) in each configuration memory by setting CSL = '1' ( S407), reconfiguration is performed with CON = '0'.

  After the configuration is completed normally, the process proceeds to the initialization process (S241). Note that the processing of S402 to S403 may shorten the startup time and reduce the memory capacity by preparing a configuration memory for VerUP only for a part of the configuration memory (for example, only the configuration memory 4). .

This system can be applied regardless of the frame sequential type or the simultaneous type. As shown in FIG. 80, by simultaneously pressing one or more keys on the operation device,
The program version of the endoscope 1 The program version of the light source 17 The communication result between the endoscope 1 and the processor 13 The communication result between the light source 17 and the processor 17 The status error display of the light source 17 (for example, turret error, A message for displaying RGB unit error, RGB filter (19, 20) error, ON switch error, ignition error, lamp tent use, spare lamp change) for a certain period may be prepared.

As described above, according to the present invention,
Depending on the type of the endoscope 1 (or the CCD 2), the index image can be controlled to have an optimal size and position according to the endoscope image, and an image that can be easily observed by the user can be provided.

-According to the image size of the endoscopic image, the index image can be controlled so as to have an optimal size and position, and an image that can be easily observed by the user can be provided.
In the same endoscope 1 (CCD2), even if the image size is changed, it is possible to control the index image to be the same, and even if the image size is changed, the endoscope can be used without any discomfort to the user. Images and index images can be observed.

    -When the endoscopic image overlaps with the index image, the index image is deleted, and the overlapping of the images does not make it difficult for the user to observe the endoscopic image, thereby improving the efficiency of examination, examination, and surgery. Can be planned.

    ・ When the endoscope image overlaps with the endoscope related information, the endoscope related information is erased, and the overlap with the image does not make it difficult for the user to observe the endoscope image. The efficiency of examination and surgery can be improved. The endoscope related information includes information read from the memory 8 in the endoscope 1.

    By changing the setting item of the system setting screen item “Index Delete”, it is possible to control the display or non-display of an index image during recording during a recording operation such as release or capture. Thus, it is possible to deal with users who need an index for recorded images and users who do not need an index image, and can provide an easy-to-use endoscope apparatus or endoscope system.

    -D. of setting item Remote Control of Table 4A. For example, when “TYPEB” is selected in F, the setting item of “Index Delete” may be automatically switched to ON. Thus, display control of the index image can be performed according to the connected peripheral device.

The setting of “Index Delete” may be changeable through filing devices 308 and 357, photography devices 307 and 356, recording devices 86 and 87, and a serial interface or parallel interface via SIO 250 or PIO 251. As a result, the display control of the index image can be controlled from the peripheral device (Note that not only the index but also all the endoscope related information, setting of various setting screens, and reading and changing the setting state of the operation device are ( (Including invalidation of operation keys), possible by peripheral devices.)
As shown in FIG. 8, since the index image can be synthesized only with specific graphic data (for example, an arrow cursor), an endoscope other than the arrow cursor (for example, 624, 624 ′) is used when generating the index image. Even if related information (for example, 600 to 623, 600 ′ to 623 ′, an error message, the messages in FIGS. 75 and 76 to 80, etc.) overlaps with the endoscope image, it is not included in the index image (not synthesized). Therefore, an index image that can be easily observed by the user can be provided.

  The index image may be displayed only on the endoscope synthesized image output in the synthesis process 2 (99) by creating only the video + synthesis process 93, and the synthesis processing circuit 102 also generates the index image. Alternatively, it may be output to the synthesis process 1 (61) or the endoscope composite image of the digital encoder 62.

  The white balance setting state can be displayed on an operation device (for example, INC and COMP LEDs on the top of WHITE BAL. (404) on the front panel 69) or an endoscope composite image (FIGS. 77 to 79), or Since it is also possible to notify with a sound from the buzzer 71, even if the user forgets to take the white balance, it can be easily and instantly noticed, and there is no trouble in the examination and the operation.

    -In addition, since white balance can be controlled corresponding to a plurality of light sources (17, 17a), processors can be combined regardless of the type of light source, and the range of user equipment selection is widened and used. An easy-to-use endoscope device and endoscope system can be provided.

When the light source 17 is turned off, the user can turn on the light source 17 by displaying an error on the endoscope composite image or notifying the buzzer 71 with sound during white balance processing. The user can provide an optimal endoscopic image to the user because the white balance process can be performed correctly and the user can provide the endoscope-related information as shown in FIGS. 72 and 73 with a dedicated display control switch. The display can be controlled by (for example, the REMOVE DATA key 528 of the keyboard 14). (Endoscope-related information includes information stored in the memory 8 in the endoscope 1)
Endoscope-related information to be synthesized by the video + compositing process 93 and endoscope-related information to be synthesized by the synthesis processing circuit 102 can be displayed separately (for example, only the video + synthesizing process 93 is always displayed in 619 to 621). ). The display contents of endoscope related information can be controlled (selection of display or non-display) according to the image quality and display range of multiple image outputs. Output can be selected. It is possible to provide an endoscope apparatus or an endoscope system having the characteristics as described above.

<Second Embodiment>
FIG. 86 shows another embodiment of a detailed block diagram (see FIG. 8) of the character / mask / image composition 211. In FIG. 8, the image data is reduced by the reduction processing 269 and then stored in the memory 8 (112). However, in FIG. 86, the image data is stored as it is in the memory 8 (112) and then displayed. The image is reduced by the reduction process 269 ′ at the time of READ.

  As described above, the reduction processing 269 ′ is performed after passing through the memory 8 (112) → the bidirectional buffer 270, so that the endoscope composite image display screen that is not reduced to the memory 8 (112) is written, and the memory 8 (112 ) To READ after the READ.

FIG. 87 shows a position where the memory 8 (112) is written without being reduced in the configuration of FIG. The registers wstart, wstartv, wendh, and wndv indicate the range of the image to be written to the memory 8 (112) without being reduced, and the WRITE processing to each POSITION of the memory 8 (112) is performed in the specified range. (In this embodiment, the row and column address values of each POSITION are different from those in FIG. 45.)
FIG. 88 shows the position to read each POSITION in the memory 8 (112) in the configuration of FIG. Registers mrstart, mrstartv, mrendh, mrendv indicate the range of the image to be read when the upper left corner of each POSITION of the memory 8 (112) is the base point ((x, y) = (0, 0)). The image is reduced by the reduction process 269 ′ to become an index image.

  FIG. 89 is a table showing a setting example for creating an index in the configuration of FIG. 89. By controlling the memory control circuit 312, the bidirectional buffer 310, the memory 112, the reduction process 269 ′, and the mask process 266 based on the table of FIG. 89, the memory 8 (112 ) And READ to create and display an index image.

  As described above, in FIG. 8, since the image is reduced and then written in the memory 8 (112), it cannot be handled when the user wants to see the enlarged image later. However, in the present embodiment, the memory 8 (112) Since the image before the reduction is written in, the request can be met even when the user wants to see the enlarged image later.

<Third Embodiment>
Next, another embodiment of control relating to the index display of FIGS. 26 to 29 will be described. By controlling the operation device, for example, the front and rear index display may be controlled as follows. (In the following description, the display mode is 4: 3, but the same applies to display modes 5: 4 and 16: 9.)
Here, FIG. 90 (FIGS. 90-1 to 90-3) shows an example of index display control when Fn (536) + cursor (544) “←” is input when there are four frames. FIG. 91 (FIGS. 91-1 to 91-3) shows an example of index display control when Fn (536) + cursor (544) “→” is input when there are four frames. FIG. 92 (FIGS. 92-1 to 92-3) shows an example of index display control when Fn (536) + cursor (544) “→” is input when an index is one frame. FIG. 93 (FIGS. 93-1 to 93-3) shows an example of index display control when Fn (536) + cursor (544) “←” is input at the time of one index. Hereinafter, a description will be given with reference to FIGS.

(I) When four frames are displayed, when the keyboard 14 and keyboard 2 (45) Fn (536) + cursor (544) "←" is input, the previous index image can be displayed as shown in FIG. The index image can be moved. (When displaying the index image immediately before the POSITION 0 image (index image “1” in FIG. 90), the POSITION 63 may be displayed (displaying the index image “64” in FIG. 90). The operation when Fn (536) + cursor (544) “←” is input may be invalidated and warning such as an error sound or an error display may be issued so as not to shift to POSITION 63 ((ii) and below). The same applies to the processing of
(Ii) When four frames are displayed, when the keyboard 14 and the keyboard 2 (45) Fn (536) + cursor (544) “→” is input, the next index image can be displayed as shown in FIG. The index image can be moved.

    (Iii) When one frame of index is displayed, when the keyboard 14 and keyboard 2 (45) Fn (536) + cursor (544) “←” is input, the previous index image can be displayed as shown in FIG. The index image can be moved.

    (IV) When one frame of index is displayed, when inputting Fn (536) + cursor (544) “→” of the keyboard 14 and keyboard 2 (45), the next index image can be displayed as shown in FIG. The index image can be moved.

  If there is no index image before or after (the image corresponding to the memory 8 (112) is not stored) and the Fn (536) + cursor (544) is input, the operation is invalidated. A warning such as an error sound or an error display may be given.

  On the other hand, frames 3660 to 3663 for automatically selecting an index image are displayed when the dedicated key or a plurality of keys are simultaneously pressed by the operation device, or when the operations (i) to (iV) are performed / the index list is displayed (FIG. 94). When the selection confirmation key (for example, ENTER 542, 546) is input in a state where the frame is displayed, the unreduced internal view stored in the memory 8 (112) in FIG. 86 is displayed. The mirror composite image display screen may be displayed without being reduced by controlling the memory control circuit 312, the bidirectional buffer 310, the memory 112, the reduction process 269 ′, and the mask process 266. (From this, the index image is used as a search image, and as described in the second embodiment, the uncompressed endoscope composite image display screen stored in the memory 8 (112) can be easily and reliably obtained. It is possible to display it on.) The frames 3660 to 3663 can be moved to another index image from the cursor (544).

  Note that an image to be written and read in the memory 8 (112) may be a compressed image by providing an encoding / combining process (not shown), and both an index image and an uncompressed endoscope composite image display screen are stored. You may do it.

  Further, a number may be added so that it is possible to easily confirm in which POSITION of the index image the memory 8 (112) (or how much the index image is stored in the memory 8 (112)). (FIG. 95).

As described above, the index image can be moved to the previous or next index image by a keyboard operation.
<Fourth Embodiment>
Next, an embodiment relating to transmitted illumination in the control between the processor 13 and the light source 17 will be described. When a transmission illumination switch (not shown) on the operation panel 25 of the light source 17 is input, it is possible to measure the increase in the amount of light and confirm the distal end position of the endoscope 1 by the extracorporeal transmitted light (for details, refer to Patent Document 6). reference). This embodiment relates to a transmission / reception process between the processor 13 and the light source 17 (via signal lines 28a and 28b) in the case of transmitted illumination.

  FIG. 96 shows an operation flow relating to transmitted illumination between the processor 13 and the light source 17. First, when a transmission illumination switch of the light source 17 is input (S501), a switch start command for the RGB filter 19 and the special light filters 20a, 20b, and 20c is transmitted (S502).

  Next, the processor 13 that has received the command performs monochrome setting (the same processing as the monochrome processing by inputting the B / W key 511 of the keyboard 14) (S503), and transmits a normal reception command indicating that the command has been normally received. (S504). After receiving the normal reception command, the light source 17 retracts the RGB filter 19 and the special light filters 20a, 20b, and 20c from the optical path (S505), and changes the switching state of the RGB filter 19 and the special light filters 20a, 20b, and 20c. A command to be notified is transmitted (S506).

  After receiving the command, the processor 13 transmits a normal reception command (S507). After receiving the normal reception command, the light source 17 increases the amount of light and holds it for a certain period (for example, 7 s), and the tip position of the endoscope 1 is confirmed (S508). After the predetermined period, a command for notifying the switching state of the RGB filter 19 and the special light filters 20a, 20b, and 20c is transmitted (S509).

  After receiving the command, the processor 13 transmits a normal reception command (S510). After receiving the normal reception command, the light source 17 transmits a switching start command for the RGB filter 19 and the special light filters 20a, 20b, and 20c (S511).

  After receiving the command, the processor 13 returns to the setting state before the monochrome setting in S503 (S512). (If the RGB display is performed before the transparent illumination is performed, the RGB display is performed, and the B / W key 511 is used. In the case of monochrome display, leave it as monochrome display.) Then, a normal reception command is transmitted (S513).

After receiving the normal reception command, the light source 17 returns the RGB filter 19 and the special light filters 20a, 20b, and 20c to the state before the saving in S505 (S514).
In the operation flow of FIG.
-When a communication error occurs (for example, when an abnormal command is sent or received, a timeout error, a parity error, an overrun error, a checksum error, etc.)
When a command different from the sequence order of S501 to S514 is transmitted / received (for example, when a switching state notification command is transmitted / received instead of the switching start command at the sequence timing of S502)
When all the keys (or some keys) of the operation switch of the light source 17 are input. All of the operations when all the keys (or some keys) of the operation device of the processor 13 are input (or Part)), stop the transillumination process,
The processor 13 is returned to the setting state before the monochrome setting (setting state before the transmission illumination process in FIG. 96). The state before the light source 17 is saved in the above S505 (setting state before the transmission illumination process in FIG. 96). You may make it return to.

  On the other hand, when the setting item is corrected in each setting screen, the item corrected on the screen may be retained until the selection confirmation key is input or the screen is shifted to another screen by inputting the ESC key or the like. (For example, in a system setting screen having a plurality of pages, after the setting item on the first page is corrected, the corrected item is retained even if the page shifts to 2-3 pages and returns to page 1 again. May be good).

  The recording devices 86 and 87 may be an MO, a DVD-RAM, a DVD ± R / RW, an HDD, a non-volatile memory, and a printer. The endoscope composite image to be recorded is an uncompressed image (RGB, YcrCb) or JPEG / JPEG2000 / MPEG1 / MPEG2 / MPEG4 / H. A format such as H.264 / TIFF / AVI / BMP / WMV may be used. In that case, by controlling the CPU 74, the CPU I / F 6 (209), and the image capture unit 215, the endoscope composite image in the memory 9 (113) is uncompressed or JPEG / JPEG2000 / MPEG1 / MPEG2 / MPEG4 / H. .
