DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 through 25, several preferred embodiments of the present invention will be described. The present invention is directed to stand-alone, computer peripheral scanners which, in their conventional form, include a connection to and requirement that they be operatively connected to a computer for processing digital signals sent by either the charged couple device (“CCD”) or a contact image sensor (“CIS”) incorporated within the scanner. The digital signals are then processed in the computer, and stored in a conventional storage media, such as a removable hard drive, 3.5 inch floppy disk, Zip-Drive® or the equivalent. The present invention is directed to incorporation of removable, or portable data storage media, i.e., memory, within the scanner itself. The present invention, therefore, enables the user to scan an image with, and store the digital data representation of the image in, a portable memory in the scanner itself, and eliminates the need for having a computer operatively connected thereto during the scanning process. The scanned image may then be stored on the portable memory, such as a 3.5 inch floppy disk, for example. The disk then may be removed from the scanner upon completion of scanning, and may be taken to a remote computer for further processing.
Referring to FIG. 1, a first preferred embodiment of the present invention is shown, including a conventional CCD-type flatbed scanner 20, housing 22, glass platen 24 and hinged lid 26. Also shown at 28 is a disk drive into which a conventional 3.5 inch floppy diskette 30 may be inserted for storage of digital data generated during the scanning process. Also shown on the scanner housing is control panel 32, which will be described in greater detail in conjunction with FIGS. 3 and 4.
Referring to FIG. 2, a second preferred embodiment of the invention is shown adapted for use in a CIS-type scanner 34. The scanner 34 includes a housing 36, glass platen 38, hinged cover 42, and a CIS scanner positioned on a carriage 40. A CIS scanner of this type is described in commonly owned U.S. Pat. No. 5,907,413, incorporated by reference as if set forth fully herein. Housing 36 also incorporates a conventional disk drive, such as a disk drive 44 for a conventional 3.5 inch floppy disk 46.
Referring to FIG. 3, a third preferred embodiment is shown, including a conventional transmissive/reflective type scanner 50, a housing 52, reflective scanning platen 56 and a transparency holder 54. This type of transmissive/reflective scanner is of the type disclosed in commonly owned U.S. Pat. No. 5,705,805, entitled Transmissive/Reflective Optical Scanning Apparatus; commonly owned U.S. Pat. No. 5,814,809 entitled Transmissive/Reflective Optical Scanning Apparatus and in commonly owned U.S. Pat. No. 5,574,274. Referring to FIG. 3, scanner 50 also incorporates a conventional disk drive into which a removable conventional, preferably, formatted, 3.5 inch floppy diskette 58 may be used for purposes of the present invention. The housing 52 includes a control panel 60 which includes a liquid crystal display 62 (“LCD”) and a multi-function control button 64.
Referring to FIG. 4, an alternate control panel 66 is shown having LCD display 68 and a plurality of control buttons. Control button 70 controls the mode of operation, either color, or black and white, with the light emitting diode (“LED”) 72, when energized indicating the color mode of operation. The black and white mode of operation is indicated when LED 74 energized. Control button 78 controls the resolution of the scanner, with a high, low and medium resolutions preferred. LED's 80, 82 and 84 indicate whether the selected resolution is high, low or medium, respectively. Control button 86 is for controlling whether the LCD display is “on” or “off”, the “on” being indicated simply by having an image on the display 68, and “off” being indicated by an absence of a display. Control button 88 is the erase control button, in which case an image stored in the disk drive may be erased. Control button 76 controls advance of the image displayed to the next image stored in the media. Button 90 controls the data compression of raw data.
Alternatively, and as shown in FIG. 3, the alternate control panel 60, control panel includes a multi-function control button 64 with “left”, “right”, “up”, “down”, and “enter” control functions, as is conventional. With such a multi-function control button 64, the various operational control choices are displayed as a series of menus on the LCD 62, with a cursor or pointer being controlled by operator movement of the multi-function button.
Referring to FIGS. 1 through 4 above, the present invention scanner provides for either reflective or transmissive scanning, and flatbed or handheld scanning, as is conventional and, at various resolutions, as also is conventional. However, the present invention also provides for transfer of the digital data representative of each scanned image directly to a portable memory positioned in the scanner itself. Alternatively, of course, an alternate transfer path may be incorporated into the scanner whereby digital data may be transferred directly to a computer, as is found in conventional scanners of this type.
Preferably the portable memory incorporated into a scanner of the present invention is a 3.5 inch floppy diskette, as is well known. Also, the present invention may be used in conjunction with other types of conventional data storage media, such as a flash memory card (also known as a PCMCIA card); a 100 MB Zip-Drive; a 120 MB, 3.5-inch diskette using a 120 MB, 3.5-inch disk drive available from O.R. Technology, Campbell, Calif., as its model FD-3120A (drive has industry standard ATAPI IDE interface); and also may be adapted to use a compact disk (CD) with write capability. The conventional 3.5 inch floppy diskette holds approximately 1.44 megabytes of data, which is equivalent to approximately 30 to 40 images, after compression, for a standard resolution, color VGA, 640×480 pixel image.
With respect to a standard or normal resolution for flatbed scanners of the general type described herein, a 300 dots per inch (“dpi”) resolution is typical. At this resolution, using a color mode of operation, it is expected that a conventional 3.5 inch floppy diskette would store approximately 10 to 12 images wherein the object is of a standard letter size, i.e., 81⁄2×11 inches, with presently available data compression technology.
Also, as will be appreciated, incorporation of a portable storage media such as a floppy diskette, etc., will require adaptations to the scanner such as provision for a battery and AC power supply to the memory device. With respect to the different types of portable storage media, a 3.5 inch floppy disk is most preferred, with a Zip-Drive, holding approximately 100 megabytes of data, being also preferred.
Referring to FIG. 5, a flow chart of programming steps for controlling the data collection, display and storage features of the invention will be described. Each of the blocks in the block diagram represent a programming step, or a series of programming steps which are available as conventional software, and/or readily generated using conventional programming techniques. Control routine 92 begins by starting the function at step 94 at the conventional on/off power button, not illustrated in FIG. 4. Once the system is energized, the mode of operation is selected at step 96, being either a color or black and white mode of operation. As shown in FIG. 4, control step 96 is selected with button 70, and LED 72 indicating a color mode of operation and LED 74 indicating a black and white mode of operation. Once the mode of operation is selected, the degree of resolution is selected, at step 98. Corresponding control button 78, with high 80, medium 82 and low 84 resolution LEDs also shown on the front of the control panel in FIG. 4. With conventional scanners, the medium resolution is typically 300 dpi, a high resolution is typically 600 dpi, with as high as 1200 dpi. For scanner operation, a low resolution is typically approximately 100 dpi.
Once the resolution has been selected, the scanning function is begun, at step 100, during which the carriage is advanced across the length dimension of the scanner to scan the object image and, through a CCD or CIS camera the object image is converted into digital data representative of the object image. Referring to FIG. 4, the scan or advance control button is shown at 76. Once the data has been scanned, data may be compressed, in step 102, using a conventional data compression routine, such as JPEG, or the equivalent. It is within the scope of the present invention that a single, predetermined data compression routine may be incorporated into the computer software application program controlling the operation of the scanner, or that several data compression options may be available, with further control options made available at the control panel (not shown) for selecting a particular data compression technique. Once the data has been compressed, it is then stored on the removable digital data storage media, step 104 indicating being stored on disk. Alternatively, no data compression is also an option, step 103. Data Compression is controlled by button 90, as shown on FIG. 4. Once the data has been stored on the disk, it may also be displayed on the LCD display, step 106, corresponding to display 62 (FIG. 3) or display 68 shown at FIG. 4. The stored data may be erased as described above in conjunction with control button 88.
Referring to FIGS. 6–9, a fourth preferred embodiment 200 of the present invention is a conventional flat bed scanner that incorporates a personal computer (PC) central processing unit (CPU) underneath the scanner platen and adapted to control conventional scanning, editing, input and output functions. The PC CPU is not shown in FIGS. 6–9, but can be conveniently positioned within the housing of the scanner, preferably underneath the platen of the scanner. The scanner 200 includes a top cover 202 and a housing 204. The front of the scanner includes a control panel 206 which is preferably flush with the level of the scanner which includes the platen. The shape, style and overall external configuration of the scanner may take many forms, one preferable form of which is illustrated in FIGS. 6–9. Referring to FIG. 7, the scanner 200 is shown with its cover 202 in a partially raised position, exposing a recess 210 that is configured and adapted for use as a handle to raise and lower the cover. The top surface of the scanner housing includes a scanning bed 212 having a conventional glass platen. The front of the scanner includes a conventional 3.5′′ floppy disk drive 214 and a conventional 100 MB drive 216, commonly referred to as a “Zip®” brand drive. Both of these drives are operatively connected to the CPU in a conventional fashion.
Referring to FIG. 8, this preferred embodiment also, preferably includes a conventional share port 218, a conventional printer point 220 and a conventional accessory port 222 for use, optionally, for peripherals such as a document feeder.
With reference to FIG. 9, the control panel 206 includes controls and indicators for numerous functions used during operation of the scanner. Start button 226 initiates the selected operation, such as scan, or copy, both of which are conventional functions in scanners, as is well known. Stop/clear button 228 controls and permits the current scanner function to be stopped during operation. This function is used for printer set up operations and to return any settings back to default values. Also, pressing and holding the stop/clear button 228, preferably for 5 seconds, will reset a conventional file name counter. Mode button 230 functions to toggle between copying images to a connected printer, which may be either black and white or color, and scanning to a floppy or Zip® disk, which may be black and white, gray scale or color. The desired operation is selected, preferably, by pressing the mode button repeatedly to cycle through the various options. Compression button 232 functions to choose the amount of file compression desired for the scanned image. The options included, preferably, are low, medium and high compression. Conventional compression techniques are used in the present invention. As is well known, lower compression results in a larger file size but provides better image quality. In the preferred embodiment, compression setting is not available for the copy function or when scanning in a black and white mode. The control panel also includes the +/− button 234, with the − function illustrated at 236 and the + function illustrated at 238. These buttons function to specify the number of pages to be printed, when the scanner is in the copy mode of operation. When the scanner is in scan mode, these buttons function to increase or decrease the resolution level. Also, when the mode button 230 is pressed and held for at least 5 seconds, preferably, and with the printer mode selection selected, the +/− buttons 234, 236 and 238 function to choose a printer mode number that corresponds to a printer model. Various printer models are supported, as desired, with the present invention.
Resolution control button 240 functions to choose the level of detail desired for a particular image to be scanned. The resolution is increased by using the + button 238 and decreased by pressing the − button 236. The preferred resolution settings for the scan function, in dots per inch, for the default settings for low, medium and high resolution are as follows:

    
    
        In black and white mode: 150, 300 and 600
        In gray scale: 75, 150 and 300.
        In color: 75, 150 and 300.
    
    


In the copy function the resolution settings, in dots per inch, the default settings for low, medium and high resolution are as follows:

    
    
        In black and white: 300, 450 and 600.
        In color mode: 100, 150 and 300.
    
    


In this preferred embodiment of the present invention, the settings shown on the LED display panel during the copy mode refer not to the resolution setting itself but rather to the number of copies to be printed.
Scan area selection button 242 functions to choose the maximum size that can be scanned by the scanner. In the present invention, the preferred sizes are A4, which is 8.5′′ by 11.7′′; and letter, which 8.5′′ by 11′′ and “auto”. Auto refers to enablement of an automatic edge detection system, which is conventional. In this mode, the scanner will complete an initial pass to find the edges of the photo or document and then scan only the detected area. When using this mode, it is preferable to keep the lid closed.
The document function button 244 functions to automatically set preferred defaults for quickly scanning a text document. In the present invention, the preferred default settings are B/W for the scan mode. Although in this mode color documents may be scanned, the resulting output would be black and white. The default resolution is 300 dpi, the scan area is letter size and no compression is performed. After the document button is pressed to select the default settings, individual settings may be altered as desired, and then scanning may be started by pressing the start button 226.
The “save to” button 246 functions to select whether the scanned images are saved to a Zip® disk or to a floppy disk. In the present invention, it is preferred that pressing and holding the “save to” button for at least 5 seconds will cause the CPU to attempt to format the floppy disk into an IBM-compatible formatted disk. This function will erase all files on the disk unless it is write protected. Various file formats may be used, but in the present invention the PCX file format is preferred for files scanned in black and white mode, and Jpeg file format is preferred for files scanned in the color mode.
Also, preferably, saved files are assigned numeric file names in sequence, starting from img01.pcx or img01.jpg, repeating after img99. Preferably, the counter may be reset back to img01 by pressing and holding the stop/clear button 228 for at least 5 seconds. In this case the LED display will show “F1” to indicate that the counter has been reset to indicate file number “1”.
Although the present invention could use an internal clock, the preferred embodiment does not and all saved files are date stamped as Jan. 1, 1999.
Various indicator lights and labels may also be used on the control panel 206. For example, in the preferred embodiment, indicator lights 248 and 250 indicate B/W and Color, respectively in the copy mode. Indicator lights 252, 254 and 256 indicate B/W, Gray and Color, respectively in the scan mode. Indicator lights 258, 260 and 262 indicate high compression, medium compression and low compression, respectively.
Above the LED 263 display, indicator lights 264, 266 and 268 indicate an unformatted disk, a full disk and no disk, respectively. Above, the resolution button 240, indicator lights 270, 272 and 274 indicate high resolution, medium resolution and low resolution, respectively. Above the scan area control button 242, indicator lights 276, 278 and 280 indicate A4, letter and auto sizes respectively. Above the “save to” control button 246 the indicator lights 282 and 284 indicate selection of the Zip® drive or diskette, respectively.
This fourth preferred embodiment of the present invention is a 36-bit, stand-alone scanning appliance with scan, copy, image-saving, image-compression and disk-formatting capabilities combined into a single scanner. This preferred embodiment is a stand-alone scanner which means that there is no need to connect the scanner to a computer. Rather, once power is supplied to the scanner, it is ready to scan and copy, save and perform its other functions. Because it is a stand alone scanning device, it comes with its own file saving features built in. The Iomega brand Zip® drive accommodates a standard 100-MB, IBM-compatible, formatted Iomega Zip® disk and also includes a standard floppy drive that accommodates conventional 3.5′′ floppy disks. This preferred embodiment includes 600×600 dpi optical resolution and scans in color, gray scale and black and white modes. Also, preferably, it is adapted for and may include conventional image editing, document management, and OCR software for scanning photos and documents, thus making the entire scanning process simple and convenient.
Typical optional uses for the present invention would include the scanner to scan images and then send the scanned images to a printer. In this configuration, a standard printer cable from the printer's parallel port is preferably connected to the present invention's printer port 220. Then, the “mode” control button 252 is held for at least 5 seconds, and the +/− keys are operated to choose the printer mode number corresponding to the printer model that is connected. The start button is then pressed to save the printer mode number into the computer's CPU memory and set up is complete.
In an alternate mode of operation, the same printer may be shared with a PC and the scanner of the present invention. In this application two standard parallel printer cables are used, with one cable connected from the printer to the printer port 220 and the second printer cable connected from the PC's parallel port to the “share port” 218 shown in FIG. 8. During operation in this mode, the scanner of the present invention must be turned “on”.
In yet another mode of operation, the scanner of the present invention may be configured to work with Microtek brand, standard 10-page auto document feeder, such as model ADF-600L, for simplified multi-page document scanning. In this mode of operation, the upper lid 210 is removed by raising it up 90° and lifting it straight up. Then the metal posts of the ADF are inserted into the holes on the right side of the scanning bed, shown at 288 and 290 in FIG. 7. The ADF is then plugged into the accessory port 222 in the scanner, and is ready for automatic document feed mode.
The present invention also includes numerous conventional warning indicators that are displayed on the LED display panel. Detection processing and display of these indicators are conventional, and may include messages such as “write-protected disk”, “no-disk”, “disk full”, “disk not formatted”, “warm up” and so forth, as is conventional.
Described below are several operations of the present invention.

Both of these projectors include a conventional control panel, not shown. In the preferred embodiment projectors, the control panel is located on the top of the unit. As described above, these LCD projectors are of conventional design.
With reference to FIGS. 19A and 19B, the remote control 568 for the LCD projector 510 will be described. FIG. 19A shows the top view of the controller 568. The controller 568 enables the user to interact with the projector 510 on projector 510's onscreen display and customize various operations. The remote controller also includes features for the laser pointer and, when used with a Windows® based operating system, functions as a remote mouse. The laser pointer is activated at laser pointer button 570. The remote mouse curser button, which functions as a mouse curser when used with a Windows® based operating system, is shown at 572. Left and right click mouse buttons 574 and 576, respectively, are also shown, for use as these functions when used with a Windows® based operating system. Other conventional functions may be controlled by the controller 568 with input button 578, mute control button 580, lamp control button 582, menu selection control 584, channel increase control 586, enter function 588, volume decrease control 590, channel decrease control 600, and volume increase control 602.
With reference to FIG. 19B, the bottom view of the remote control 568 is shown. IR transmitter 604 is shown at the top. Additional control button 606 is shown near the middle of the remote control. Control 606 functions as does the left mouse click button for a Windows® based system. Battery compartment 608 is shown near the lower part of the controller.
With reference to FIG. 20, a typical scanner projection system arrangement is illustrated. In the FIG. 20 schematic, a scanner 610 is shown with a VGA monitor cable output 614. The scanner 610, as shown in FIG. 20, may be any of the previously described scanners, provided that they are stand alone scanners having a central processing unit of at least a 486 capability, and having the adaptations as described elsewhere in the specification, for providing output to an LCD type projector 510. The VGA monitor cable 614 are connected to the corresponding inputs 536, and 562, as described above, for the LCD projector 510. In this regard, and in general, if the computer was connected to PC 1 in, the related connected channels should also be PC 1 audio in and mouse 1 input connectors. The connectors should not be connected across channels such as PC 1 in, PC 2 audio and so forth. In order to utilize the projector 510s internal, amplified stereo speakers, the preferred mini-stereo-to-mini-stereo audio cable should be connected to the appropriate PC 1 or PC 2 audio in connector at the rear of the projector 510. The other end of the cable should be connected to the audio output connector of the IBM-compatible lap top or notebook computer.
If the remote mouse feature is desired for use with the multimedia projector's remote control mouse, then it is also necessary to connect to the serial mouse cable.
Referring to FIG. 21, a flow chart 616 illustrating programming steps used in the present scanner projector system during operation will be described. Each of the blocks in the flow chart 616 represent a software routine, or a series of software routines, which are available as conventional software, and/or readily generated using conventional programming techniques.
Image digital data processing commences with user selection of settings for the projector scan 618 as previously described and subsequent actuation by depression of the scanner start button 620. Once the processing has commenced the scanner is calibrated by operation of one or a series of calibration routines 622. Following calibration one line of image digital data 624 is acquired by the digital camera and processed sequentially by one or a series of shading correction routines 626 and one or a series of DCR color and gamma correction routines 628, following which the one line of image digital data is written to video memory 630.
If the line of image digital data written to video memory 630 is not the last line 632 of the image scan, the next line of image digital data is acquired and processed as aforesaid. This sequence of image digital data acquisition and processing steps is repeated line by line until the last line of the image scan has been acquired at 624, processed at 626 and at 628, and written to video memory at step 630.
As the lines of the image scan digital data are written to video memory 630, the image digital data stored in video memory 630 is projected onto the screen 512 via LCD projector 510 via a VGA or SVIDEO output 508. Once the completed image digital data have been stored and displayed, the image is available to the image browsing function 634 via one or a series of routines which permits user selection of the displayed image scale, browsing and centering of any selected region of the display image 662, as further described.
Referring to FIG. 22, flow chart 617 illustrating the various programming steps used in changing the scaling factor for the size of the image display and for browsing and/or centering a region of the displayed image will be described. Each diamond symbol in the flow chart 617 represents a user operation of a key of the IR Remote Control 514 and each block represents a software routine, or a series of software routines, which are available as conventional software, and/or readily generated using conventional programming techniques. Changing the displayed image 662 is initiated by user depression of the various keys of the IR Remote Control 514. A software routine 636, or a series of software routines, query whether a key of the IR Remote Control 514 is actuated. If a key of the IR Remote Control 514 is actuated a series of software routines 638, 640, 642, 644, 646 and 648 query which key has been actuated. If the IR Remote Control 514 up key 522 is actuated, software routine 638, or a series of software routines, initiate operation of software routine 650, or a series of software routines, to change the vertical position of the displayed image 662 pursuant to an algorithm of the type Y1 equals Y1−((480*4)/ZOOMFACTOR [ZOOMSTATUS]) where Y represents the vertical axis, as is conventional.
If the IR Remote Control 514 down key 526 is actuated, software routine 640, or a series of software routines, initiate operation of software routine 652 or a series of software routines, to change the vertical position of the displayed image 662 pursuant to an algorithm of the type Y1 equals Y1+((480*4)/ZOOMFACTOR [ZOOMSTATUS]), where Y again represents the vertical axis, as is conventional.
If the IR Remote Control of 514 right key 524 is actuated, software routine 642, or a series of software routines, initiates operation of software routine 654, or a series of software routines, to change the horizontal position of the displayed image 662 pursuant to an algorithm of the type X1 equals X1+((640*4)/ZOOMFACTOR [ZOOMSTATUS]), where X represents the horizontal axis, as is conventional.
If the IR Remote Control 514 left key 520 is actuated, software routine 644, or a series of software routines, initiates operation of software routine 656, or a series of software routines, to change the horizontal position of the displayed image 662 pursuant to an algorithm of the type X1 equals X1−((640*4)/ZOOMFACTOR [ZOOMSTATUS]), where X again represents the horizontal axis, as is conventional.
If the IR Remote Control 514 zoom in key 518 is actuated, software routine 646, or a series of software routines, initiates operation of software routine 658, or a series of software routines, to change the scale of the displayed image 662 pursuant to an algorithm of the type which modifies the horizontal X1 and the vertical Y1 values of the displayed image 662 and which further sets up a scaling factor for display of a smaller portion of the image digital data stored in video memory 630 and displays a smaller portion of the stored image digital data than previously displayed, resulting in enlargement of that portion of the image which is displayed.
If the IR Remote Control 514 zoom out key 516 is actuated, software routine 648, or a series of software routines, initiate operation of software routine 660, or a series of software routines, to change the scale of the displayed image 662 pursuant to an algorithm of the type which modifies the horizontal X1 and vertical Y1 values of the displayed image 662 and which further sets up a scaling factor for display of a larger portion of the image digital data stored in video memory 630 and displays a larger portion of the stored image than previously displayed, resulting in a reduction of that portion of the image which is displayed.
