DETAILED DESCRIP'rION OF' A PREFEI~RED EMBODIMENT
_ _ _ _ _ _ _ _ _ __ _ _ Referring to the drawings in detail, and initially to Fig. 1 thereof, an information processing appara-tus according to one embodiment of the present invention is divided into a character or word processing section 18, a display section, an~ an image processing and mixing section. The latter section includes a central processing unit (CPU) 1 for controlling the image processing and mixing operation, with CPU 1 being connected through a main bus line 40 to a read only memory (ROM)
2, a random access memory (RAM) 3, a system control device 4 which includes a timing control device, and a key-board control device 5. The latter key-board control device 5 is further connected through a bus line to a key-board 6 having a joy stick and function keys (not shown) an~ t~rnugh whlch ope~ation ^f the image processing and mixing section can be controlled.
Also connected to CPU 1 through the aforementioned bus line ~0 is an image converting device 7 which includes an image sensor 8 connected to CPU 1 through an image pick-up control device 10 and bus line 40. Image sensor 8 is designed to read image in~ormation from a document, as will be latter described, and to supply such image information through image pick-up control device 10 to a buffer memory 12, preferably a random access memory (RA~1), which ls also connected to bus line 40. Image converting device 7 also includes an image printer 9, such as a laser printer, and an image prin-ter control device 11 for controlling the printing operation by image printer 9 in response to an appropriate signal supplied thereto. The image printer con-trol device 11 is also connected to CPU 1 through the aforementioned bus line 40.
ReEerring now to Fig. 2, there is shown a sheet of paper 28 which contains image information ~hereon (not shown).
Al-though any dimension paper can be used with this invention, the image sensin~ opera-tion will now be described for A--4 type paper in which the sheet of paper containing the image ls 297 mm long and 210 mm wide with a margin which provides an effective information region 270 mm long and 184 mm wide~ The sheet of paper 28 is transported in the direction of arrow A and image information recorded thereon is read out by a line image sensor 29 of image sensor 8. Line image sensor 29 includes a plurality of sensing elements disposed in a straight horizontal line, with each sensing elemen-t being adapted to detect the presence o a black or white area at the respective sampling point correspond-ing thereto and which genera-tes one pixcel, that is, dot ir.foLIllaLion o.. one hit for eash bl 2C~ OL ~h1te pic-.u~-e elelmerlt sampled. For example, each ~ixcel or outp~t from each sensing element may be a logic level "1" signal for the detection of a black image area and a logic level "0" signal for a whi-te image area. The outputs of the respective sensing elements of line image sensor 29 are picked up or read out in series by image pick-up control device 10 and stored in the aforemen-tioned buffer memory 12.
The vertical resolution of such read-out information is determined by the feeding pitch of paper 28. Thus, for example, if the feeding pitch is selected so that line image sensor 29 reads or detects 7 lines/mm, then 1,890 lines (270 mm x 7 lines/mm) are read or d~tected by line image sensor 29 for the efective information region of the paper. The horizontal resolution is determined by the density of image sensing elements which are arranged on the aorementioned horizontal line in line image sensor 29. Thus, for example, if the horizontal density is selected as 8 pixcels/mm, then 1,472 pixcels (184 mm x 8 pixcels/mm), are provided for each detected li.ne of the effective ~nforma-tion ~ 3'~'7'~
region? Accordingly, 2,782,080 pi~cels (1,472 pixcels/line x 1,890 lines) are provided for tlle effective information region o~
the size A-4 paper. As previously discussed, these pixcels or out-puts of the respective sensing elements are picked up and read out in series by image pick-up control device 10 and stored in the aforementioned buffer memory 12. Since each pixcel is equivalent to one bit of information, it should be appreciated ~hat buffer memory 12 i5 required to have a storage capacity of 347.76 kilobytes (2,782,0~0 bits . 8 bits/byte). Practically speaking, buffer memory 12 is provided with a storage capacity of 512 kilobytes.
Referring back to Fig. 1, a display section of the apparatus of Fig. 1 is shown to include a display device 13, such as a 15-inch CRT (cathode ray tube), which utilizes a horizontal ~"r.L, ng S-L cq-~cncy ~;f ~PPrO.~imate1 Y 5V Y~l~ and Wh' Ch "~ r.' C~ 2UL
I an interlace scanning operation. Preferably, the picture screen I of CRT 13 has dimensions such that its length is greater than its width. With such CRT, the horizontal resolution is selected as 4 pixcels/mm and the vertical resolution is selected as 2.6 lines/mm.
It should be appreciated that the resolution of the CRT in the horizontal direction is approximately one-half (1/2) of the reso-lution of line image sensor 29 and, in the vertical direction, is approximately one-thircl (1/3) o that of line image sensor 29.
In other words, the number of bits of information that can be dis-played on CRT 13 :is one-sixth (1/6) of that stored in buffer memory 12.
Accordingly, a display buffer memory 14 is provided having a capacity to store image information corresponding to 630 lines with 736 pixcels per line, as shown in Fig. 3, which is one-sixth (1/6) o:E the required storage capacity of buffer memory 12. In th:is manner, the information stored in buffer memory 12 is reduced and transferred to display buffer memory 14 ~ 7'~
for display on t~e screen of CRT 13. For example, the image information stored in buffer memory 12 can be sampled so as to reduce the length of each horizontal line of image information by one-half (1/2) and the length of each vertical line of image information by one-third (1/3), and the sampled information can then be transferred to display buffer memory 1~. This may be accomplished by transferring the entire image stored in buffer memory 12 into display buffer memory 14 with a reduction in resolution. Alternatively, a portion of the image, for example, one-sixth of the image, stored in buffer memory 12 can be transferred to display buf~er memory 14 with no reduction in resolution, as will hereinafter be described. The display section of the apparatus further includes an image display control device 16 which reads the lmage information from display buffer memory 14 and transfers such information to CRT
~ 13 to be displayed. In like manner, a character display control ~ - -I device 17 is provided for performing a similar operation with characters or words from word processing section 18. In addition, a cursor control device 15 is provided which exhibits a horizontal cursor line X and a vertical cursor line Y on CRT 13, with the intersection of such lines being utilized, as will be discussed later in greater detail, to display the image information from display buffer memory 1~ at a deslred location on CRT 13.
Also associated with the display sec~ion and the image information and mixing~section is a digital mass storage ~DMS) system which can, lf desired, be utilized to store the !
.
Also connected to CPU 1 through the aforementioned bus line ~0 is an image converting device 7 which includes an image sensor 8 connected to CPU 1 through an image pick-up control device 10 and bus line 40. Image sensor 8 is designed to read image in~ormation from a document, as will be latter described, and to supply such image information through image pick-up control device 10 to a buffer memory 12, preferably a random access memory (RA~1), which ls also connected to bus line 40. Image converting device 7 also includes an image printer 9, such as a laser printer, and an image prin-ter control device 11 for controlling the printing operation by image printer 9 in response to an appropriate signal supplied thereto. The image printer con-trol device 11 is also connected to CPU 1 through the aforementioned bus line 40.
ReEerring now to Fig. 2, there is shown a sheet of paper 28 which contains image information ~hereon (not shown).
Al-though any dimension paper can be used with this invention, the image sensin~ opera-tion will now be described for A--4 type paper in which the sheet of paper containing the image ls 297 mm long and 210 mm wide with a margin which provides an effective information region 270 mm long and 184 mm wide~ The sheet of paper 28 is transported in the direction of arrow A and image information recorded thereon is read out by a line image sensor 29 of image sensor 8. Line image sensor 29 includes a plurality of sensing elements disposed in a straight horizontal line, with each sensing elemen-t being adapted to detect the presence o a black or white area at the respective sampling point correspond-ing thereto and which genera-tes one pixcel, that is, dot ir.foLIllaLion o.. one hit for eash bl 2C~ OL ~h1te pic-.u~-e elelmerlt sampled. For example, each ~ixcel or outp~t from each sensing element may be a logic level "1" signal for the detection of a black image area and a logic level "0" signal for a whi-te image area. The outputs of the respective sensing elements of line image sensor 29 are picked up or read out in series by image pick-up control device 10 and stored in the aforemen-tioned buffer memory 12.
The vertical resolution of such read-out information is determined by the feeding pitch of paper 28. Thus, for example, if the feeding pitch is selected so that line image sensor 29 reads or detects 7 lines/mm, then 1,890 lines (270 mm x 7 lines/mm) are read or d~tected by line image sensor 29 for the efective information region of the paper. The horizontal resolution is determined by the density of image sensing elements which are arranged on the aorementioned horizontal line in line image sensor 29. Thus, for example, if the horizontal density is selected as 8 pixcels/mm, then 1,472 pixcels (184 mm x 8 pixcels/mm), are provided for each detected li.ne of the effective ~nforma-tion ~ 3'~'7'~
region? Accordingly, 2,782,080 pi~cels (1,472 pixcels/line x 1,890 lines) are provided for tlle effective information region o~
the size A-4 paper. As previously discussed, these pixcels or out-puts of the respective sensing elements are picked up and read out in series by image pick-up control device 10 and stored in the aforementioned buffer memory 12. Since each pixcel is equivalent to one bit of information, it should be appreciated ~hat buffer memory 12 i5 required to have a storage capacity of 347.76 kilobytes (2,782,0~0 bits . 8 bits/byte). Practically speaking, buffer memory 12 is provided with a storage capacity of 512 kilobytes.
Referring back to Fig. 1, a display section of the apparatus of Fig. 1 is shown to include a display device 13, such as a 15-inch CRT (cathode ray tube), which utilizes a horizontal ~"r.L, ng S-L cq-~cncy ~;f ~PPrO.~imate1 Y 5V Y~l~ and Wh' Ch "~ r.' C~ 2UL
I an interlace scanning operation. Preferably, the picture screen I of CRT 13 has dimensions such that its length is greater than its width. With such CRT, the horizontal resolution is selected as 4 pixcels/mm and the vertical resolution is selected as 2.6 lines/mm.
It should be appreciated that the resolution of the CRT in the horizontal direction is approximately one-half (1/2) of the reso-lution of line image sensor 29 and, in the vertical direction, is approximately one-thircl (1/3) o that of line image sensor 29.
In other words, the number of bits of information that can be dis-played on CRT 13 :is one-sixth (1/6) of that stored in buffer memory 12.
Accordingly, a display buffer memory 14 is provided having a capacity to store image information corresponding to 630 lines with 736 pixcels per line, as shown in Fig. 3, which is one-sixth (1/6) o:E the required storage capacity of buffer memory 12. In th:is manner, the information stored in buffer memory 12 is reduced and transferred to display buffer memory 14 ~ 7'~
for display on t~e screen of CRT 13. For example, the image information stored in buffer memory 12 can be sampled so as to reduce the length of each horizontal line of image information by one-half (1/2) and the length of each vertical line of image information by one-third (1/3), and the sampled information can then be transferred to display buffer memory 1~. This may be accomplished by transferring the entire image stored in buffer memory 12 into display buffer memory 14 with a reduction in resolution. Alternatively, a portion of the image, for example, one-sixth of the image, stored in buffer memory 12 can be transferred to display buf~er memory 14 with no reduction in resolution, as will hereinafter be described. The display section of the apparatus further includes an image display control device 16 which reads the lmage information from display buffer memory 14 and transfers such information to CRT
~ 13 to be displayed. In like manner, a character display control ~ - -I device 17 is provided for performing a similar operation with characters or words from word processing section 18. In addition, a cursor control device 15 is provided which exhibits a horizontal cursor line X and a vertical cursor line Y on CRT 13, with the intersection of such lines being utilized, as will be discussed later in greater detail, to display the image information from display buffer memory 1~ at a deslred location on CRT 13.
Also associated with the display sec~ion and the image information and mixing~section is a digital mass storage ~DMS) system which can, lf desired, be utilized to store the !
.
3~7'7 informatiorl in buf~er memo~y 12, and a D~IS col~trol device 34 for controlling t~e operation of the DMS system 35.
As previously mentioned, the apparatus of Fig. 1 also includes a character or word processing section 18 which is shown surrounded by a broken line. In order to better illustrate the distinction between word processing section 1 and the image information and mixing section, CRT 13 and character display control device 17, as aforementioned, are shown to be included within the broken line of word processing section 18. As with the image information and mixing section, word processing section 18 includes a central processing unit (CPU) 19 for controlling the operation thereof. A memory 20, such as a random access memory (RAM) having a capacity of, for e~c.~.pl~, 5~ k~1Obyt~s, îs A~ SO prsv~ d~d For storin~ ch~ At2~ _ r word code date o~ an 8-bit ASCII code, and is connected to CPU
19 through a main bus line 50. Hereinaftert character or word information will only be referred to as character information with the understanding that word information is also included there-in. A magnetic disk drive 219 also of word processing section 18, is provided for driving two magne~ic disks, such as of the diskette or floppy disk type, and is connected to tne aforementioned bus line 50 through a disk control device 22 which controls the reading out and writing in of information from the magnetic disks.
In the present apparatus, one of the magnetic disks is a system disk including a previously stored word processing program which is read or loaded into RAM 20 at the start of operation of word processing section 18. The other magnetic disk is a work disk used for storing eharacter information, for example, corresponding to appro~imately 120 pages of A-4 type sheet. A key-board 23 includes keys of the type normally Eound on conventional English-language typewriters, function keys and 10 additional keys, and ~ 71~
is connected to the aforernentioned bus line 50 through a key-board control device 24. Tl~ls, characters can be typed at key-board 23 and supplied to RAM 20 for storage therein and to character display control device 17 for display on the screen of CRT 13 by means of a suitable character generator in the character display control device 17. At the same time, character information which is typPd at key-board 23 is recorded on the magnetic work disk and, if desired, can be prin~ed out as a hard copy by a character printer 25 which is connected to the aforementioned bus line ~0 through a character printer control device 26. It should be appreciated that word processing section 18 is adapted to edit character information which is displayed on CRT 13 by, for exam~le, correct;ng, sllpplementing cancelLing and the like, such character information. Further, the image information and mixing section and the word processing section 18 are connected together through main bus lines 40 and 50 and a bus control device 27 whereby character information in the latter section can be transferred to the former section~
Various operations of the apparatus of Fig. 1 will now be described with reference Figs. 4-11. As shown in Fig. 4, image information from sensor 8 of image converting device 7 is read into buffer memory 12 through image pick-up control device 10. As previously discussed, the information region in buffer memory 12 is reduced by one-third (1/3) in the longitudinal or vertical direction and by one-half (1/2) in the lateral or hori.zon~al di~ection and then transferred to display bufer memory 14. One method of accomplishing this will now be described in detail.
To better illustrate this reduction operation, reference will now be made to Figs. llA-llC. As shown therein, an 8 x 8 3~
rectangular region, that is, a region containing ei~ht lines with eight bits per line, is stored in buffer memory 12. In the first step, the eight lines ~ 8 are divided into _ se-ts where 1 ~ n ~ 7, with n being equal to 3 in the example which will now be described. In other words, three sets of lines 3~ ~4~ ~6~ and ~7- ~8 are procluced. The first bits from each line are simultaneously read out so that respective bits from each set are supplied through respective OR gates. For example, the first bits in lines ~ 3 are supplied to a first OR gate, the first bits in lines ~4- ~6 are supplied to a second OR gate, and the first bits in lines ~7- ~8 are supplied -to a third OR gate. Thus, when any of the first bits in lines Ql- Q3 are at logic level "1", the output from the first OR gate is also at loglc levcl "1' and this output constitutes the first bit in a newly formed horizontal line ~11 ThP same operation is performed with the second and third OR gates, the outputs of which -constitute the first bits in newly formed horizontal lines ~12 and ~13. This vertical or Y-reduction operation sequentially continues for each of the second through eighth bits in the lines until the region of Fig. llA is reduced to the region of Fig. llB.
To perform the horizontal or X-direction reduction, each horizontal line is divided into n se-ts which, as previously stated, is equal to 3 in this example. For example, the first three bits of each of lines ~ 1' Ql2 and ~13 are grouped into a first set, the next two bits of each line are grouped into a second set, and the last three bits oE each line are grouped into a third set. The bits of information in the firs-t line ~11 are each supplied to one input of respective AND gates, and the other inputs thereof are supplied with a bit of information which is predeterminecl in accordance with a mask pattern. For example, a mask pa-ttern for the eight bits of each line can be comprised
As previously mentioned, the apparatus of Fig. 1 also includes a character or word processing section 18 which is shown surrounded by a broken line. In order to better illustrate the distinction between word processing section 1 and the image information and mixing section, CRT 13 and character display control device 17, as aforementioned, are shown to be included within the broken line of word processing section 18. As with the image information and mixing section, word processing section 18 includes a central processing unit (CPU) 19 for controlling the operation thereof. A memory 20, such as a random access memory (RAM) having a capacity of, for e~c.~.pl~, 5~ k~1Obyt~s, îs A~ SO prsv~ d~d For storin~ ch~ At2~ _ r word code date o~ an 8-bit ASCII code, and is connected to CPU
19 through a main bus line 50. Hereinaftert character or word information will only be referred to as character information with the understanding that word information is also included there-in. A magnetic disk drive 219 also of word processing section 18, is provided for driving two magne~ic disks, such as of the diskette or floppy disk type, and is connected to tne aforementioned bus line 50 through a disk control device 22 which controls the reading out and writing in of information from the magnetic disks.
In the present apparatus, one of the magnetic disks is a system disk including a previously stored word processing program which is read or loaded into RAM 20 at the start of operation of word processing section 18. The other magnetic disk is a work disk used for storing eharacter information, for example, corresponding to appro~imately 120 pages of A-4 type sheet. A key-board 23 includes keys of the type normally Eound on conventional English-language typewriters, function keys and 10 additional keys, and ~ 71~
is connected to the aforernentioned bus line 50 through a key-board control device 24. Tl~ls, characters can be typed at key-board 23 and supplied to RAM 20 for storage therein and to character display control device 17 for display on the screen of CRT 13 by means of a suitable character generator in the character display control device 17. At the same time, character information which is typPd at key-board 23 is recorded on the magnetic work disk and, if desired, can be prin~ed out as a hard copy by a character printer 25 which is connected to the aforementioned bus line ~0 through a character printer control device 26. It should be appreciated that word processing section 18 is adapted to edit character information which is displayed on CRT 13 by, for exam~le, correct;ng, sllpplementing cancelLing and the like, such character information. Further, the image information and mixing section and the word processing section 18 are connected together through main bus lines 40 and 50 and a bus control device 27 whereby character information in the latter section can be transferred to the former section~
Various operations of the apparatus of Fig. 1 will now be described with reference Figs. 4-11. As shown in Fig. 4, image information from sensor 8 of image converting device 7 is read into buffer memory 12 through image pick-up control device 10. As previously discussed, the information region in buffer memory 12 is reduced by one-third (1/3) in the longitudinal or vertical direction and by one-half (1/2) in the lateral or hori.zon~al di~ection and then transferred to display bufer memory 14. One method of accomplishing this will now be described in detail.
To better illustrate this reduction operation, reference will now be made to Figs. llA-llC. As shown therein, an 8 x 8 3~
rectangular region, that is, a region containing ei~ht lines with eight bits per line, is stored in buffer memory 12. In the first step, the eight lines ~ 8 are divided into _ se-ts where 1 ~ n ~ 7, with n being equal to 3 in the example which will now be described. In other words, three sets of lines 3~ ~4~ ~6~ and ~7- ~8 are procluced. The first bits from each line are simultaneously read out so that respective bits from each set are supplied through respective OR gates. For example, the first bits in lines ~ 3 are supplied to a first OR gate, the first bits in lines ~4- ~6 are supplied to a second OR gate, and the first bits in lines ~7- ~8 are supplied -to a third OR gate. Thus, when any of the first bits in lines Ql- Q3 are at logic level "1", the output from the first OR gate is also at loglc levcl "1' and this output constitutes the first bit in a newly formed horizontal line ~11 ThP same operation is performed with the second and third OR gates, the outputs of which -constitute the first bits in newly formed horizontal lines ~12 and ~13. This vertical or Y-reduction operation sequentially continues for each of the second through eighth bits in the lines until the region of Fig. llA is reduced to the region of Fig. llB.
To perform the horizontal or X-direction reduction, each horizontal line is divided into n se-ts which, as previously stated, is equal to 3 in this example. For example, the first three bits of each of lines ~ 1' Ql2 and ~13 are grouped into a first set, the next two bits of each line are grouped into a second set, and the last three bits oE each line are grouped into a third set. The bits of information in the firs-t line ~11 are each supplied to one input of respective AND gates, and the other inputs thereof are supplied with a bit of information which is predeterminecl in accordance with a mask pattern. For example, a mask pa-ttern for the eight bits of each line can be comprised
4~'7'7 of the loglc level bits 101, 01 and 101 which are illustrated as being divided into the aforementioned three se-ts. Thus, the first bit of line 11 is sup~lied -to one input of a first AND gate and another input thereof is supplied with the logic level "1" bit of the masking pattern. A second AND gate receives the second bit of information from line 11 at one input -thereof, and at another input, receives the logic level "0" bit from the masking pattern. In like manner, a third AND gate receives the -third bit of information from line Qll at one input thereof, and at another input thereof, receives the logic level "1" bit from the masking pattern. The outputs from the three AND gates are then supplied to respective inputs of an OR gate which produces the first bit of information in the first line of the reduced region of Fiq. llC. The remainlng bits of lnformat'on i n lines ~ 12 and 13 are processed in the same manner. The reason that the masking patterns have been utilized is to obtain a reduced image information region (Fig. llC) which closely approximates the original image information region (Fig. llA). It should be appreciated that, by means of the above reduction or shrinkage operation, the image information region of Fig. llC has been reduced by a factor or 3/8 as compared with the image information region of Fig. llA.
Alternatively, an information region which covers one-sixth (1/6) of the information stored in buffer memory 12 may be read into display buffer memory 1~ with a one-to-one correspondence therebetween and therefore, without any reduction in size of the actual information region. In this latter operation, which will hereinafter be referred to as a zoom operation, image information from a region comprised of 630 lines with 736 bits or pixcels per line that is stored in buffer memory 12, is transferred ~ 7~
or read into dlsplay buEfer memory 14, as shown in Fig. 5, and thereafter displayed on the screen of CRT 13. In order to select the proper 630 line by 73~ bit region to be transferred to display buffer memory 1~, hereinafter referred to as the zoom region, a picture image formed from all of the image information stored in buffer memory 12 is first displayed on the screen of CRT 13. A point P corresponding to the upper leEt-hand corner of the zoom region is ~hen selected by cursor control device 15. A zoom command is then given and image information in a rectangular region surrounded by 630 lines in the vertical or Y-direction and 736 bits in the horizontal or X-direction, from point P, is transferred or read into display buffer memory 14. Thereafter, a pict1~re image formed from the image informa~ion stored in display buffer memory 14 is displayed on the screen of CRT 13.
It should therefore by appreciated that the image information and mixing section in the apparatus of Fig. 1 is adapted to displa~
the entire contents of buffer memory 12 by performing ~he first a~ove described operation and thereby reducing the size and resolution of the entire image, or by performing a zoom operation in which only a portion of the information stored in buffer memory 12 is displayed by CRT 13 with no reduction in resolution. It should further be appreciated that the zoom display enables an operator to discriminate the original displayed picture image which may be obscure or have insufficient resolution as a result of the aforementioned reducing operation.
The apparatus of Fig. 1 is also adapted to perform a one-half display operation in which image information supplied Erom image converting device 7 and/or character information from word processing section 1~ are displayed on only one-half, for example, the upper half portion, of the screen or CRT 13. In this manner, for example, when a draEt of eharacter information is 3~7~
typed lnto the word processing s~ction 1~, such character information can be displayed on the upper half portion of the screen of CRT 13 to be edited,with the corrected or edited character information being displayed on the lower half portion of the screen. Thus, the line of sight of the operator need not be changed during such editing operation, as with prior art apparatus.
Various editing operations for the information will now be described with reference to Figs. 6-10. Fig. 6 shows an erase operation in which a portion of the information is cancelled or erased. This operation is performed by first displaying all of the information or contents of buffer memory 12 on the screen of CRT 13. The region to be erased is then chosen by seiecting a point P in the upper left-hanu corner or ti-e region to be erased and a point Q in the lower right-hand corner of the region to be erased, by means of cursor control device 15., CPU 1 then generates positional information by selecting addresses in buffer memory 12 corresponding to a rectangular region defined by the points P and ~ and shown by the hatched region in Fig. 6. An erase command, for example, at key-board 6, is then given whereby data in buffery memory 12 corresponding to the hatched portion is erased or cancelled in accordance with a predetermined program. In other words, a logic level "O"
signal is substi-tuted for all of the bits oE information in buffer memory 12 corresponding to the rec-tangular region to be erased. The contents of bu~fer memory 12 can simultaneously or subsequently be transferred to display buffer memory 14 to be displayed~on the screen of CRT 13, with the hatched portion being erased thereerom.
Referring now to E'ig. 7, there is shown a cut operation .
3~
in which the aforementioned rectangular reglon determined by -the points P and Q, rather than being erased, is the only region that is not erased. In other words, the hatched portion oE
Fig. 7 is erased, and the inEormati.on in the selected rectangular region :is retained.
~ transfer or mo~e operation is shown in Fig. 8 in which a selected rectangular region is transferred or moved to another location. In this case, the rectangular hatched region determined by the points P and Q, in a manner similar to the selection of the rectangular region of Fig. 6 r is transferred to a different location, for example, the location determined by point R in Fig. 8. Also, at the time of such transfer, the original rectangular region defined by points P and Q is erased.
With this operation, a picture image, ror example, corresponding to the image information stored in buffer memory 12, is first displayed on CRT 13, and points P and Q are selected by cursor control device 15. Addresses corresponding to points P and Q
are fed to CPU 1 which, in response thereto, selects the rectangular region to be transferred. Also, cursor control device 15 selects the position to which the rectangular region is to be transferred by choosing a point R in the upper left-hand corner of the transfer location which will correspond to point P
in the upper left-hand corner at the original location. The address correspondiny to point R is also fed to CPU 1 which, in accordance with a predetermined program, correlates the addresses in buffer memory ~2 of the information at the original location with those at the transfer location. Information i.ncLuded in the hatched region at the original location is then read out from buEfer memory 12 and stored at addresses, also in buffer memory 12, corresponding to the transfer location, for 7~7 each bit of information. The hatched region is also erased in the manner previously discussed in regard to Fig. 6.
The apparatus of Fig. l is also adapted to perform a copy operation, as shown in Eig. ~, which is identical to the transfer operation of Fig. 8 with the exception that the information in the rectanyular region at the original location is not erased.
The apparatus of Fig. 1 is also adapted to perform a reducing and transfer operation, as shown in Fig- lO, in which a rectangular reyion defined by points P and Q, is reduced in size, as previously discussed in regard to Figs. llA-llC, and -transferred to a new position determined by a selected point R. In other words, the reducing and transfer motion of ~ig. 10 ls a co~bination o~ operations previsusl~- desclibed in regard to Figs. llA-llC and Fig. 9. In this case, the data at the original location defined by points P and Q is shown as not .. . -being erased, although such data could be erased in accordance with the operation oE Fig. ~.
It should be appreciated that the above editing operations are utilized as part of an overall graphic processl~g operation used to frame the original picture image at a desired location and with a desired size. This is achieved by reading dot or bit information into buffer memor~ 12 and display buffer memory 14 and by utilization of cursorcontrol device 15. In this manner, the image information can be transferred from one position to another, erased,~reduced or any combination of the three.
It should be appreclated tha-t the present invention is designed to utilize the above-described operations to combine both image and character information on the screen of CRT 13 and 7t7 on a sheet oE paper 2~. lhus, image information from display buffer memory 14 is supplied -through image display control device 16 and displayed on the screen of CRT 13. Also, character information from RAM 20 of word processing section 18 is displayed on the screen of CRT 13 through character display control device 17. At the same time, X- and Y-cursor lines generated by cursor control device 15 are also displayed on the screen of CRT 13. A composite image and character display is therefore obtained, as shown, for example, in Fig. 13D, by utilizing the above-described editing operations for the image information along with a conventional editing operation for word processing section 18. It should therefore be appreciated that for the display operation, the image information and mixing seclion operates independently of the word processing section 18.
However, in order to provide a hard copy of the composite display at image printer 9, it is necessary that the character code (ASCII) information in RAM 20 be written into buffer memory 12 by means of CPU 1, so as to provide a merging or mixing operation. Thus, main bus line 50 in word processing section 18, which is connected to RAM 20, is connected to main bus line 40 of the image information and mixing section through the aforementioned bus control device 27. In this regard, character informa-tion from RAM 20 is supplied to CPU 1 which, in turn, reads the information into buffer memory 12 at a previously determined position corresponding to the display on the screen of CRT 13. In this manner, a hard copy of the composi-te display of CRT 13, which is stored in buffer memory 12, can be reproduced :by image printer 9. A partial flow diagram of the above operation is shown in Fig. 4.
Because the image information in buffer memory 12 corresponds to a region which is six times as great as the image information :region in display buffer memory 14 and the region displayed by CRT 13, character information which is displayed ~ 7 by CRT 13 anc~ which is also stored in RAM 20 may be too small in comparison with the image information stored in buffer memory 12.
Accordingly, the character information from RAM 20 is supplied through bus control device 27 to CPU 1 which enlarges the character information in accordance with a predetermined program, and supplies the enlarged character information to buffer memory 12. For example, there is shown in Fig. 12 a display containing the letter "A" ~hich is displayed on the screen of CRT 13 and which is formed of 1~ es of information with eight bits per line. If the character lnformation of ASCII code format is con-verted into date of 112 (8 x 14) pixcels and written into buffer memory 12, the character display "A" becomes equivalent to a 1 x 2 mm display which is too small in comparison with the image informati ~ in buf.fer mem~ry 12. Accordingly, the character code information read out from R~ 20 is transmitted through bus control device 27 to RAM 3 which is controlled by CPU 1. CPU 1 is adapted to discriminate characters corresponding to character code informa-tion stored in Pl~ 3 and to read out corresponding character dot information of double font size, that is, 28 lines for each character with 16 bits per line, which is stored in ROM 2. CPU then writes the corresponding character code information from ROM 2, tha-t is, in regard to Fig. 12, a double font size letter "A", into buffer memory 12 at an address corresponding to its origlnal position on CRT 13. ~n this manner, buffer memory 12 stores both image and character information therein from which a hard copy can be produced by image printer 9.
~ t should further be appreciated that, when character information is also stored in buffer memory 12, the aforementioned editing operations by the image in:Eormation and mixing section can be simultaneously or separately performed on the character information with respect to the image information. ln this manner, characters typed on ~ey-boarcl 23 can be mixed with images from image sensor 8 3'~
with any desired relationship therebe-tween in buffer memory 12.
Further, as previously discussed, the da-ta stored in buffer memory 12 can be supplied, if necessary, through DMS controller 34 to be stored in D~S system 35.
In order to better understand the operation of t~e present invention, the editing of image and character information will now be described with reference to Figs. 13A-13D. In such case, first and second picture images PICS. 1 and 2 formed on two sheets as shown in Figs. 13A and 13B are to be combined with the character information shown in Fig. 13C to produce a final composite display or document, as shown in Fig. 13D, which contains both lmage and character information arranged in a selected manner. First, by utilizing the keys on key-board 23 in the word processinq section 18, ch2rac' 2, inlor~tlon which is shown as being surrounded by a two-dot chain line in Fig. 13C, is stored in R~ 20 after being processed by CPU 19, and is also displayed on the screen of CRT 13 through character display control device 17. It should be appreciated that a one-half display operation may be utilized in displaying the character information on CRT 13.
The operator then utilizes word processing section 18 to perform an editing operation, such as a correction or erasing operation, to thereby rearrange the character information to provide room for the two picture images PICS. 1 and 2, as shown in Fig. 13D.
After such changes have been made in the character information, the edited character in~ormation can be stored on the working magnetic disk of magnetic disk drive 21.
After the character information has been edited, as aforementioned, the sheet of paper containing the picture image PIC. 1 of E'ig. 13A is placed in image sensor 8 of image converting device 7 and the operator then ihitiates a read command through key-board 6. This lat-ter command is supplied lg ~ ~ ~3~3,7t~
through key-hoard control device 5 to CPU 1 which lr~terprets the command according to a predetermined program in order to actuate image sensor 8 to carry out the reading operation. The image information of picture image PIC. 1 which is read out from image sensor 8 is supplied through image pick-up control device 10 and stored in buffer memory 12. At the same time, a drawing display command punched into key-board 6 results in the image information stored in buffer memory 12 being displayed on the screen of CRT 13, for example, as shown in Elig. 13A.
While viewing the displayed picture image PIC. 1, a region to be edited, for example, a rectangular region defined by points Pl and Ql and obtained in much the same manner as the rectangular region of Fig. ~, and a desired posit~on Ri; are selected by cursor control device 15. By means of key-board 6, the amount of reduction of theEicture image PIC. 1 is selected and an appropriate command to pexform such operation is given.
Accordingly, the image information in the rectangular region defined by points Pl and Ql is read into CPU 1 from buffer memory 12 and is processed in the former. The processed image information from CPU 1 is then written back into buffer memory 12 at selected addresses corresponding to the selected point Rl and with the aforementloned selected reduction or shrinkage. In addition, CPU 1 performs an erase operation in which the original inEormation in the addresses of buffer memory 12 corresponding to the rectangular region defined by points Pl and Ql are erased. The edited picture image PIC. 1 stored in buffe~ memory 12, along with the previously edited character information, are also displayed on the screen of CRT 13.
In like manner, the picture image PIC. 2 is read by image sensor 8, edited by CPU 1 and the edited image information is stored in buffer memory ]2. In other words, the size of t7t',;js~
plcture image PIC. 2 is reduced and the reduced image is transferred to a desired pOSitiOII, in the same manner as previously dlscussed in regard to picture image PIC. l. The resultant combination of image and character information is shown in Fig. 13D and is displayed on the screen of CRT 13.
It should be appreciated that the character information displayed on CRT 13 is produced and edited in word processing section 18 and displayed on CRT 13 through character display control device 17. However, the image information is produced in the image information and mixing section and displayed on CRT 13 through image display control device 16. In order to produce a hard copy, an appropriate command is generated at key-board 6 whereby the character code (ASCII) information which is stored in R~v; 2û is supplied through bus contL-ol device 2/ and stored in RAM 3. The contents of RAM 3 are then enlarged, as previously discussed in regard to Fig. 12, and corresponding character information from ROM 2 of a larger font are read into buffer memory 12 at positions corresponding to the original character data. Thereafter, when a display command is initiated at key-board 6, a composite image comprised of image information and character information is generated from dot or bit information stored in buffer memory 12 only. Further, when a print command is given, the contents of buffer memory 12 are transferred through image printer control device ll to image printer 9 where a hard copy of the composite image, for example, as shown in Fig. 13D, is produced.
It should be appreciated that various modifications may be made by one of ordinary skill in the art wi-thin the scope o~ this invention. E'or example, although the character edi.ting operation has been discussed as preceding the image editing operation, the reverse may occur. In addition, 3~i"7 al-though only English-language characters have been shown in the figures, it should be appreciatecl that various other language characters or any other symbols may be u-tilized with the word processing section 18 of this invention.
In addition, although two central processing units 1 and 19 and two key-boards 6 and 23 have been shown, it should further be appreciated that these elements can be combined to produce one central processing unit and one key-board for con-trolling both image and character editing operations.
Having described a specific preferred embodiment of theinvention with reference to the accompanying drawings, it is to be understood that the invention is not limited to that precise emhodiment, and that various changes and modifications may be eEfected -LheLein by one skille~ in the art without departing from the scope or spirit of the invention as defined in the appended claims.

Alternatively, an information region which covers one-sixth (1/6) of the information stored in buffer memory 12 may be read into display buffer memory 1~ with a one-to-one correspondence therebetween and therefore, without any reduction in size of the actual information region. In this latter operation, which will hereinafter be referred to as a zoom operation, image information from a region comprised of 630 lines with 736 bits or pixcels per line that is stored in buffer memory 12, is transferred ~ 7~
or read into dlsplay buEfer memory 14, as shown in Fig. 5, and thereafter displayed on the screen of CRT 13. In order to select the proper 630 line by 73~ bit region to be transferred to display buffer memory 1~, hereinafter referred to as the zoom region, a picture image formed from all of the image information stored in buffer memory 12 is first displayed on the screen of CRT 13. A point P corresponding to the upper leEt-hand corner of the zoom region is ~hen selected by cursor control device 15. A zoom command is then given and image information in a rectangular region surrounded by 630 lines in the vertical or Y-direction and 736 bits in the horizontal or X-direction, from point P, is transferred or read into display buffer memory 14. Thereafter, a pict1~re image formed from the image informa~ion stored in display buffer memory 14 is displayed on the screen of CRT 13.
It should therefore by appreciated that the image information and mixing section in the apparatus of Fig. 1 is adapted to displa~
the entire contents of buffer memory 12 by performing ~he first a~ove described operation and thereby reducing the size and resolution of the entire image, or by performing a zoom operation in which only a portion of the information stored in buffer memory 12 is displayed by CRT 13 with no reduction in resolution. It should further be appreciated that the zoom display enables an operator to discriminate the original displayed picture image which may be obscure or have insufficient resolution as a result of the aforementioned reducing operation.
The apparatus of Fig. 1 is also adapted to perform a one-half display operation in which image information supplied Erom image converting device 7 and/or character information from word processing section 1~ are displayed on only one-half, for example, the upper half portion, of the screen or CRT 13. In this manner, for example, when a draEt of eharacter information is 3~7~
typed lnto the word processing s~ction 1~, such character information can be displayed on the upper half portion of the screen of CRT 13 to be edited,with the corrected or edited character information being displayed on the lower half portion of the screen. Thus, the line of sight of the operator need not be changed during such editing operation, as with prior art apparatus.
Various editing operations for the information will now be described with reference to Figs. 6-10. Fig. 6 shows an erase operation in which a portion of the information is cancelled or erased. This operation is performed by first displaying all of the information or contents of buffer memory 12 on the screen of CRT 13. The region to be erased is then chosen by seiecting a point P in the upper left-hanu corner or ti-e region to be erased and a point Q in the lower right-hand corner of the region to be erased, by means of cursor control device 15., CPU 1 then generates positional information by selecting addresses in buffer memory 12 corresponding to a rectangular region defined by the points P and ~ and shown by the hatched region in Fig. 6. An erase command, for example, at key-board 6, is then given whereby data in buffery memory 12 corresponding to the hatched portion is erased or cancelled in accordance with a predetermined program. In other words, a logic level "O"
signal is substi-tuted for all of the bits oE information in buffer memory 12 corresponding to the rec-tangular region to be erased. The contents of bu~fer memory 12 can simultaneously or subsequently be transferred to display buffer memory 14 to be displayed~on the screen of CRT 13, with the hatched portion being erased thereerom.
Referring now to E'ig. 7, there is shown a cut operation .
3~
in which the aforementioned rectangular reglon determined by -the points P and Q, rather than being erased, is the only region that is not erased. In other words, the hatched portion oE
Fig. 7 is erased, and the inEormati.on in the selected rectangular region :is retained.
~ transfer or mo~e operation is shown in Fig. 8 in which a selected rectangular region is transferred or moved to another location. In this case, the rectangular hatched region determined by the points P and Q, in a manner similar to the selection of the rectangular region of Fig. 6 r is transferred to a different location, for example, the location determined by point R in Fig. 8. Also, at the time of such transfer, the original rectangular region defined by points P and Q is erased.
With this operation, a picture image, ror example, corresponding to the image information stored in buffer memory 12, is first displayed on CRT 13, and points P and Q are selected by cursor control device 15. Addresses corresponding to points P and Q
are fed to CPU 1 which, in response thereto, selects the rectangular region to be transferred. Also, cursor control device 15 selects the position to which the rectangular region is to be transferred by choosing a point R in the upper left-hand corner of the transfer location which will correspond to point P
in the upper left-hand corner at the original location. The address correspondiny to point R is also fed to CPU 1 which, in accordance with a predetermined program, correlates the addresses in buffer memory ~2 of the information at the original location with those at the transfer location. Information i.ncLuded in the hatched region at the original location is then read out from buEfer memory 12 and stored at addresses, also in buffer memory 12, corresponding to the transfer location, for 7~7 each bit of information. The hatched region is also erased in the manner previously discussed in regard to Fig. 6.
The apparatus of Fig. l is also adapted to perform a copy operation, as shown in Eig. ~, which is identical to the transfer operation of Fig. 8 with the exception that the information in the rectanyular region at the original location is not erased.
The apparatus of Fig. 1 is also adapted to perform a reducing and transfer operation, as shown in Fig- lO, in which a rectangular reyion defined by points P and Q, is reduced in size, as previously discussed in regard to Figs. llA-llC, and -transferred to a new position determined by a selected point R. In other words, the reducing and transfer motion of ~ig. 10 ls a co~bination o~ operations previsusl~- desclibed in regard to Figs. llA-llC and Fig. 9. In this case, the data at the original location defined by points P and Q is shown as not .. . -being erased, although such data could be erased in accordance with the operation oE Fig. ~.
It should be appreciated that the above editing operations are utilized as part of an overall graphic processl~g operation used to frame the original picture image at a desired location and with a desired size. This is achieved by reading dot or bit information into buffer memor~ 12 and display buffer memory 14 and by utilization of cursorcontrol device 15. In this manner, the image information can be transferred from one position to another, erased,~reduced or any combination of the three.
It should be appreclated tha-t the present invention is designed to utilize the above-described operations to combine both image and character information on the screen of CRT 13 and 7t7 on a sheet oE paper 2~. lhus, image information from display buffer memory 14 is supplied -through image display control device 16 and displayed on the screen of CRT 13. Also, character information from RAM 20 of word processing section 18 is displayed on the screen of CRT 13 through character display control device 17. At the same time, X- and Y-cursor lines generated by cursor control device 15 are also displayed on the screen of CRT 13. A composite image and character display is therefore obtained, as shown, for example, in Fig. 13D, by utilizing the above-described editing operations for the image information along with a conventional editing operation for word processing section 18. It should therefore be appreciated that for the display operation, the image information and mixing seclion operates independently of the word processing section 18.
However, in order to provide a hard copy of the composite display at image printer 9, it is necessary that the character code (ASCII) information in RAM 20 be written into buffer memory 12 by means of CPU 1, so as to provide a merging or mixing operation. Thus, main bus line 50 in word processing section 18, which is connected to RAM 20, is connected to main bus line 40 of the image information and mixing section through the aforementioned bus control device 27. In this regard, character informa-tion from RAM 20 is supplied to CPU 1 which, in turn, reads the information into buffer memory 12 at a previously determined position corresponding to the display on the screen of CRT 13. In this manner, a hard copy of the composi-te display of CRT 13, which is stored in buffer memory 12, can be reproduced :by image printer 9. A partial flow diagram of the above operation is shown in Fig. 4.
Because the image information in buffer memory 12 corresponds to a region which is six times as great as the image information :region in display buffer memory 14 and the region displayed by CRT 13, character information which is displayed ~ 7 by CRT 13 anc~ which is also stored in RAM 20 may be too small in comparison with the image information stored in buffer memory 12.
Accordingly, the character information from RAM 20 is supplied through bus control device 27 to CPU 1 which enlarges the character information in accordance with a predetermined program, and supplies the enlarged character information to buffer memory 12. For example, there is shown in Fig. 12 a display containing the letter "A" ~hich is displayed on the screen of CRT 13 and which is formed of 1~ es of information with eight bits per line. If the character lnformation of ASCII code format is con-verted into date of 112 (8 x 14) pixcels and written into buffer memory 12, the character display "A" becomes equivalent to a 1 x 2 mm display which is too small in comparison with the image informati ~ in buf.fer mem~ry 12. Accordingly, the character code information read out from R~ 20 is transmitted through bus control device 27 to RAM 3 which is controlled by CPU 1. CPU 1 is adapted to discriminate characters corresponding to character code informa-tion stored in Pl~ 3 and to read out corresponding character dot information of double font size, that is, 28 lines for each character with 16 bits per line, which is stored in ROM 2. CPU then writes the corresponding character code information from ROM 2, tha-t is, in regard to Fig. 12, a double font size letter "A", into buffer memory 12 at an address corresponding to its origlnal position on CRT 13. ~n this manner, buffer memory 12 stores both image and character information therein from which a hard copy can be produced by image printer 9.
~ t should further be appreciated that, when character information is also stored in buffer memory 12, the aforementioned editing operations by the image in:Eormation and mixing section can be simultaneously or separately performed on the character information with respect to the image information. ln this manner, characters typed on ~ey-boarcl 23 can be mixed with images from image sensor 8 3'~
with any desired relationship therebe-tween in buffer memory 12.
Further, as previously discussed, the da-ta stored in buffer memory 12 can be supplied, if necessary, through DMS controller 34 to be stored in D~S system 35.
In order to better understand the operation of t~e present invention, the editing of image and character information will now be described with reference to Figs. 13A-13D. In such case, first and second picture images PICS. 1 and 2 formed on two sheets as shown in Figs. 13A and 13B are to be combined with the character information shown in Fig. 13C to produce a final composite display or document, as shown in Fig. 13D, which contains both lmage and character information arranged in a selected manner. First, by utilizing the keys on key-board 23 in the word processinq section 18, ch2rac' 2, inlor~tlon which is shown as being surrounded by a two-dot chain line in Fig. 13C, is stored in R~ 20 after being processed by CPU 19, and is also displayed on the screen of CRT 13 through character display control device 17. It should be appreciated that a one-half display operation may be utilized in displaying the character information on CRT 13.
The operator then utilizes word processing section 18 to perform an editing operation, such as a correction or erasing operation, to thereby rearrange the character information to provide room for the two picture images PICS. 1 and 2, as shown in Fig. 13D.
After such changes have been made in the character information, the edited character in~ormation can be stored on the working magnetic disk of magnetic disk drive 21.
After the character information has been edited, as aforementioned, the sheet of paper containing the picture image PIC. 1 of E'ig. 13A is placed in image sensor 8 of image converting device 7 and the operator then ihitiates a read command through key-board 6. This lat-ter command is supplied lg ~ ~ ~3~3,7t~
through key-hoard control device 5 to CPU 1 which lr~terprets the command according to a predetermined program in order to actuate image sensor 8 to carry out the reading operation. The image information of picture image PIC. 1 which is read out from image sensor 8 is supplied through image pick-up control device 10 and stored in buffer memory 12. At the same time, a drawing display command punched into key-board 6 results in the image information stored in buffer memory 12 being displayed on the screen of CRT 13, for example, as shown in Elig. 13A.
While viewing the displayed picture image PIC. 1, a region to be edited, for example, a rectangular region defined by points Pl and Ql and obtained in much the same manner as the rectangular region of Fig. ~, and a desired posit~on Ri; are selected by cursor control device 15. By means of key-board 6, the amount of reduction of theEicture image PIC. 1 is selected and an appropriate command to pexform such operation is given.
Accordingly, the image information in the rectangular region defined by points Pl and Ql is read into CPU 1 from buffer memory 12 and is processed in the former. The processed image information from CPU 1 is then written back into buffer memory 12 at selected addresses corresponding to the selected point Rl and with the aforementloned selected reduction or shrinkage. In addition, CPU 1 performs an erase operation in which the original inEormation in the addresses of buffer memory 12 corresponding to the rectangular region defined by points Pl and Ql are erased. The edited picture image PIC. 1 stored in buffe~ memory 12, along with the previously edited character information, are also displayed on the screen of CRT 13.
In like manner, the picture image PIC. 2 is read by image sensor 8, edited by CPU 1 and the edited image information is stored in buffer memory ]2. In other words, the size of t7t',;js~
plcture image PIC. 2 is reduced and the reduced image is transferred to a desired pOSitiOII, in the same manner as previously dlscussed in regard to picture image PIC. l. The resultant combination of image and character information is shown in Fig. 13D and is displayed on the screen of CRT 13.
It should be appreciated that the character information displayed on CRT 13 is produced and edited in word processing section 18 and displayed on CRT 13 through character display control device 17. However, the image information is produced in the image information and mixing section and displayed on CRT 13 through image display control device 16. In order to produce a hard copy, an appropriate command is generated at key-board 6 whereby the character code (ASCII) information which is stored in R~v; 2û is supplied through bus contL-ol device 2/ and stored in RAM 3. The contents of RAM 3 are then enlarged, as previously discussed in regard to Fig. 12, and corresponding character information from ROM 2 of a larger font are read into buffer memory 12 at positions corresponding to the original character data. Thereafter, when a display command is initiated at key-board 6, a composite image comprised of image information and character information is generated from dot or bit information stored in buffer memory 12 only. Further, when a print command is given, the contents of buffer memory 12 are transferred through image printer control device ll to image printer 9 where a hard copy of the composite image, for example, as shown in Fig. 13D, is produced.
It should be appreciated that various modifications may be made by one of ordinary skill in the art wi-thin the scope o~ this invention. E'or example, although the character edi.ting operation has been discussed as preceding the image editing operation, the reverse may occur. In addition, 3~i"7 al-though only English-language characters have been shown in the figures, it should be appreciatecl that various other language characters or any other symbols may be u-tilized with the word processing section 18 of this invention.
In addition, although two central processing units 1 and 19 and two key-boards 6 and 23 have been shown, it should further be appreciated that these elements can be combined to produce one central processing unit and one key-board for con-trolling both image and character editing operations.
Having described a specific preferred embodiment of theinvention with reference to the accompanying drawings, it is to be understood that the invention is not limited to that precise emhodiment, and that various changes and modifications may be eEfected -LheLein by one skille~ in the art without departing from the scope or spirit of the invention as defined in the appended claims.
