Typically, when an image captured by a digital camera is to be printed, the use of a personal computer (PC) is required. For example, after the digital camera captures and stores an image, the digital camera and PC may be coupled to each other via a communication cable. Alternatively, the digital camera may store the image on a removable storage device (RSD), such as a flash memory card, which may be removed from the camera and coupled to a data port of the PC. Subsequently, the PC captures image data from the digital camera or memory card, converts the captured image data into print data, and outputs the converted print data to a printer for processing.
Alternatively, the image to be printed may be stored on a portable storage medium, such as a compact disc (CD) or digital versatile disc (DVD). In this case, the PC captures image data from the CD or DVD, converts the captured image data into print data, and outputs the converted print data to a printer for processing.
In either case, the necessity of using a PC, from both time-consumption and equipment-requirement standpoints, unduly complicates the digital-image printing process. Some existing printers accept RSDs directly and allow a user to select images stored on the RSD and directly print them via the printer, but such printers have limited utility for archiving image files and cannot transfer such files to other more suitable archival storage media without the use of a PC.
According to an aspect of the invention, an electronic device includes a housing having a first readable-optical-medium-receiving portion and a medium-removal portion, the first readable-optical-medium-receiving portion operable to receive a first optical storage medium carrying data representing a first image. The device further includes a first renderer coupled to the housing and operable to render the first image on a presentation medium at least partially disposed within the housing, the medium-removal portion operable to allow removal of the presentation medium from the housing.
The electronic device allows a user to print images stored on an optical storage medium without requiring the use of a PC, and also allows the user to archive image data stored on other storage media, such as an RSD, to the optical storage medium.
Referring to the embodiment illustrated in
The housing 20 may further include a conventional paper-feed assembly 50 and a presentation-medium-removal portion, such as a conventional slot 60, from which a presentation medium, such as paper, transparent plastic or any other medium on which an image can be printed, can be removed from the housing 20. For purposes of the ensuing discussion, it will be assumed that paper is the presentation medium employed. Additionally, the term “image” should be construed to include alphanumeric characters and/or graphical depictions.
The printer 10 may further include a user interface 70 that can be used to control printer function. The user interface 70 may include one or more controls, such as buttons 80, that, when employed by a user, instruct the printer 10 to perform functions including those described hereinafter.
Referring now to
As described above, the disc slot 30 is operable to receive an optical disc on which is stored image data. Upon receipt of the optical disc by the disc slot 30, the disc interface 100 reads the image data from the disc. Upon activation of one or more user interface controls 80 by the user, the processing unit 90 converts the image data into print data by, for example, employing a conventional printer driver (not shown). The processing unit 90 then employs the primary print-head assembly 140 to print the image represented by the print data to one or more sheets of paper. After the image has been printed to a sheet of paper, the sheet may be removed from the housing 20 via the slot 60 by, for example, rollers (not shown) in a conventional manner.
As described above, the port 40 is operable to receive an RSD on which is stored image data. Upon receipt of the RSD by the port 40, the RSD interface 110 reads the image data from the RSD. In a manner similar to that described above, upon activation of one or more user interface controls 80 by the user, the processing unit 90 converts the image data into print data and employs the primary print-head assembly 140 to print the image represented by the print data to one or more sheets of paper. After the image has been printed to a sheet of paper, the sheet may be removed from the housing 20 via the slot 60.
Alternatively, the user may utilize the user interface controls 80 to view and select images stored on the RSD placed in the port 40 and thereafter transfer or archive the files corresponding to these selected images to an optical disc in the port 30 via the disc interface 100. More specifically, responsive to input from the user via the user interface controls 80, the RSD interface 100 retrieves selected image data from the RSD in the port 40. The RSD interface 100 transfers this image data via the system bus 160 to the disc interface which, in turn, transfers the image data to the optical disc in the port 30. In this way, the user may store image data on the optical disc without the need for a PC. Storage on optical storage media is preferable to storage on RSD or other electronic storage devices since the retention rate for such optical storage is longer and less susceptible to corruption.
Similarly, upon receipt of a disc by the slot 30, the disc interface 100 may read image data stored on the disc. Upon activation of one or more user interface controls 80 by the user, the processing unit 90 employs the RSD interface 110 to write the image data to an RSD received by the RSD interface 110, thereby storing the image data on the RSD. This feature may be convenient, for example, if a user wants to take images with him or her via a digital camera, for example. Once the user transfers the image data from the optical disc to the RSD, the user can then insert the RSD in the digital camera and show the images to others.
In another embodiment, the processing unit 90 may employ, for example, a video driver (not shown) to drive the LCD display 130 and display one or more images represented by the image data read from a disc or RSD received by the housing 20. Consequently, the user, by activating one or more user interface controls 80, may review the images via the LCD display 130 and, if desired, instruct the printer 10 to print one or more of the displayed images.
In a further embodiment, upon activation of a user interface control 80 by the user, the processing unit 90 may store in the system memory 120 image data read from a disc or RSD received by the housing 20. Consequently, at a later time, the user, by activating one or more user interface controls 80, may review the stored images via, for example, the display 130 and, if desired, instruct the printer 10 to print one or more of the stored images. Moreover, the user may thus be able to transport the printer 10, thereby using the printer itself as a portable image-data-storage device.
In yet another embodiment, the disc interface 100 is operable to read image data from a DVD. Accordingly, the processing unit 90 may employ the video driver to drive the LCD display 130 with this video image data and display one or more video frames from this video image data read from the DVD. By activating one or more user interface controls 80, the user may review the frames of video images via the LCD display 130 and select one or more frames for printing, and may also control the printer 10 to print the selected images.
In another embodiment, the user, by activating one or more user interface controls 80, may select one or more images to be printed on a surface or label attached to a surface of a disc present in the slot 30. These images may comprise at least one alphanumeric character generated to the display 130 by, for example, a text editor (not shown) stored in the system memory 120 and executed by the processing unit 90. After receiving the user's selection, the processing unit 90 employs the secondary print-head assembly 150 to print the selected image to the label or disc surface.
