Abstract:
An information processor obtains information (home page) from an arbitrary information apparatus connected to the information processor via a network, and implements processing in which image data in the home page is extracted and stored so as to be correlated with a Uniform Resource Locator (URL). When the stored image data is designated with a mouse or the like, additional data are received from the information apparatus corresponding to the stored URL correlated with the stored image data, and are displayed. Thereby, image data extracted from a target homepage is used as a bookmark, which enables access to the target homepage, even if the number of bookmarks increases.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an information processing apparatus and method for displaying received data obtained by performing communication with information apparatuses connected to a network and for implementing control in recording the received data. 
     2. Description of the Related Art 
     As a result of the spread of the Internet and intranets, information apparatuses (sites) transmitting various types of information (hereinafter referred to as “homepages”) are rapidly increasing. Many tools for reading the homepages are provided. The tools have a function (generally called a “bookmark”) of recording the address of a homepage so that an operator can subsequently view the homepage when needed. 
     In the above-described conventional case, a bookmark is simply used to record the address of a homepage. When subsequently viewing the homepage, the operator may not recognize what the bookmark represents. Accordingly, in many cases, the operator needs to perform communication with the information apparatus corresponding to the bookmark in order to recognize the bookmark from displayed data. 
     In addition, when the number of bookmarks is very large, it is difficult to find a bookmark representing the desired homepage.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention is described below, with reference to the attached drawings. 
     An information processing apparatus according to a first embodiment of the present invention is described based on FIGS. 1 to  9 . 
     The information processing apparatus block diagram shown in FIG. 1, includes: a key-input unit  1 ; a key-input-data analyzing unit  2 ; a communication unit  3 ; a data analyzing unit  4 ; a coordinate input unit  5 ; a display unit  6 ; an image extracting unit  7 ; and an image storage unit  9 . 
     The key-input unit  1  designates an information source  100  connected to a network, and is used to input commands. The key-input-data analyzing unit  2  analyzes data input with the key-input unit  1 . The communication unit  3  performs data communication with the information source  100 . The data analyzing unit  4  converts the data received by the communication unit  3  into display data, and analyzes data stored in the image storage unit  9  to perform data communication with the display unit  6  and the communication unit  3 . The coordinate input unit  5  is used to input coordinates from a pointing device, and has the function of controlling a cursor and the function of drawing a rectangle indicating a region. The display unit  6  has display devices such as a CRT display and a liquid crystal display, which display windows, a selection menu, the cursor, data, and so forth. The image extracting unit  7  extracts part or all of an image on a screen. The image storage unit  9  stores image data from the image extracting unit  7 . In other words, the image storage unit  9  stores the image data, to which network information concerning the information source  100  is added. 
     The functions of the data analyzing unit  4  is described in detail below. The data analyzing unit  4  has the function of adding the network information of the information source  100  to the image data extracted by the image extracting unit  7  so that the network information is correlated with the extracted image data, and the function of performing the steps of: designating the image data stored in the image storage unit  9  in order to extract the network information correlated with the image data; obtaining new data related to the image data from the information source  10  corresponding to the network information; and causing the display unit  6  to display the obtained data. These functions are executed in the processing indicated by the flowcharts shown in FIGS. 14 to  21  (described below). The flowcharts in FIGS. 14 to  21  are stored as programs in a memory in the data analyzing unit  4  or a separate storage medium (floppy disc or the like). 
     When the programs (flowcharts shown in FIGS. 14 to  21  described below) according to the first embodiment of the present invention are activated, a data-display window  20  shown in FIG. 2 is displayed by the display unit  6 . The data-display window  20  includes a region  21  for displaying input data obtained from the information source  100 ; a window title bar  22  used for the identification and moving of the window  20 ; menu command buttons  23  and  24  for selecting operation commands; and a cursor  25  that is moved so as to correspond to coordinates input from the coordinate input unit  5 . 
     Next, processing according to the present invention is described below, with reference to FIGS. 2 to  9 . 
     First, the case where input data received from the information source  100  are displayed is described, based on FIGS. 3 and 4. To receive input data from the information source  100 , the cursor  25  shown in FIG. 2 is operated to select the menu command button  23 . Based on this selection, a pull-down menu  30  shown in FIG. 3 is displayed under the menu command button  23 . Among the items of the pull-down menu  30 , “OPEN BY LOCATING A PLACE” is selected. Based on this selection, the pull-down menu  30  shown in FIG. 3 is erased before a subwindow  40  shown in FIG. 4 is displayed. In the subwindow  40 , the place (network information) of the information source  100  is located. 
     The place is located with the key-input unit  1 . For locating a place, Uniform Resource Locator (URL) notation is generally used. The URL input in this manner is displayed in a region  41 . For stopping the operation, a cancel button  42  is selected to erase the subwindow  41 . When an open button  43  is selected for proceeding with the operation, the subwindow  40  is erased, and the URL is evaluated by the data analyzing unit  4  before being transferred to the communication unit  3 . The communication unit  3  issues a data-obtaining command to the information source  100 . Concerning a communication protocol, it is common to use a hypertext transfer protocol (http). 
     When the input data are received from the information source  100  as described above, the received input data are transferred to the data analyzing unit  4 . Since the received input data are written in a hypertext markup language (HTML), the data analyzing unit  4  analyzes the HTML, and issues text-displaying, image-drawing and graphics-displaying commands to the display unit  6  in accordance with the contents of the received input data. The display unit  6  performs displaying in accordance with the commands from the data analyzing unit  4 . 
     Next, the case where a cutout of the input data displayed by the display unit  6  is stored in the image storage unit  9  is described, based on FIGS. 5 to  8 . 
     FIG. 5 shows a condition of the display screen on which input data from the information source  100  are displayed. If an operator considers the displayed data to be useful and decides to subsequently open the data, a characteristic part of the data is cut out (extracted) and stored. 
     The cutout operation is performed such that, as shown in FIG. 6, a first coordinate point  61  of a part to be cut out is pointed to by the cursor  25  controlled by the coordinate input unit  5 , and a second coordinate point  25  of the part is similarly pointed to. A rectangle  62  formed by two line segments orthogonally crossing at the first coordinate point and two line segments orthogonally crossing at the second coordinate point is termed a selected region. In this condition, the menu command button  24  (edit) is selected to display a pull-down menu  70  shown in FIG. 7, and among its items, “CUTOUT”  71  is selected. Based on this selection, the image of the region  62  is extracted by the image extracting unit  7 . 
     For the operation of storing the extracted image, the menu command button  23  (file) is selected, and among the items of the pull-down menu  30  shown in FIG. 3, “OPEN THE SCRAPBOOK” is selected (The scrapbook has a design identical to that of the window  20  shown in FIG. 2, and the cutout image can be pasted on it). To paste the cutout image on the selected scrapbook, the menu command button  24  is selected, and among the items of the pull-down menu  70  shown in FIG. 7, “PASTE”  72  is selected. Based on this selection, the image of the region  62  extracted by the image extracting unit  7  is transferred to the display unit  6 , and it is displayed as image  80  shown in FIG.  8 . At the same time, the image data are correlated with the URL (network information) by the data analyzing unit  4 , and are stored in the image storage unit  9 . 
     Next, the case where the image data stored so as to be correlated with the URL are used to acquire and display the information related to the image data from the information source  100  is described, based on FIG.  9 . 
     When, from the image data on which the URL is pasted, the corresponding information source  100  is opened, if the scrapbook is not open, the menu command button  23  is selected, and among the items of the pull-down menu  30 , “OPEN THE SCRAPBOOK”  32  is selected. 
     Based on this selection, the URL-included image data stored in the image storage unit  9  are extracted and transferred to the display unit  6 , so that the display condition shown in FIG. 8 appears. By using the cursor  25  controlled by the coordinate input unit  5  to designate the image data  80 , the URL as well as the image data stored in the image storage unit  9  is extracted and transferred to the data analyzing unit  4 . 
     The URL is evaluated by the data analyzing unit  4  before it is transferred to the communication unit  3 . The communication unit  3  issues a data-obtaining command to the information source  100  for obtaining additional data. Based on this command, when the additional data from the information source  100  are received, the received additional data are transferred to the data analyzing unit  4 . The data analyzing unit  4  analyzes the HTML, and issues text-displaying, image-drawing and graphics-drawing commands to the display unit  6  in accordance with the contents of the received additional data. The display unit  6  performs displaying in accordance with a command from the data analyzing unit  4 , whereby displaying new data from the information source  100  as shown in FIG.  9 . 
     An information processing apparatus according to a second embodiment of the present invention is described, based on FIGS. 10,  11 A,  11 B,  12 A,  12 B,  13 A, and  13 B. 
     FIG. 10 is a block diagram of the information processing apparatus. In the second embodiment, an image demagnifying unit  8  is additionally provided. The image demagnifying unit  8  has the function of using an arbitrary magnification to reduce image data extracted by an image extracting unit  7  and transferring the reduced image data to an image storage unit  9 . 
     In the case where, when data received from an information source  100  is displayed in a data-display window (FIGS.  11 A and  11 B), an operator considers the data to be useful and cuts out the whole of the data in order to subsequently open the data, the structure of the information processing apparatus according to the second embodiment may be similarly formed to the above-described first embodiment of the present invention. However, if the operator does not wish to record the data in the original size in the scrapbook, it is possible to select the whole or part of the data before storing it in a reduced size. 
     Accordingly, as shown in FIG. 11A, a menu command button  24  is selected, and among the items of the pull-down menu  70  shown in FIG. 5, “SELECT ALL”  74  is selected to designate all the data as a selected region. Based on this selection, the image of the selected region is extracted by the image extracting unit  7 , and a predetermined demagnification (reduction) is used to demagnify (reduce) the extracted image. As shown in FIG. 6, with the rectangle  62  (surrounded by two line segments orthogonally crossing at the first coordinate point and two line segments orthogonally crossing at the second coordinate point) selected as shown in FIG. 6, the menu command button  24  is selected, and also when “REDUCTION”  73  is selected from the pull-down menu  70 , the predetermined demagnification is used to demagnify the selected image. 
     The operation of storing the demagnified image is performed such that menu command button  23  shown in FIGS. 11A and 11B is selected and “OPEN THE SCRAPBOOK”  32  is selected from pull-down menu  32  shown in FIG.  3 . To paste the demagnified image on the scrapbook, the menu command button  24  is selected, and “PASTE”  72  is selected from the pull-down menu  70 . Based on this selection, as shown in FIG. 11B, a demagnified image  90  formed by the image demagnifying unit  8  is transferred to a display unit  6 , and it is displayed. At the same time, the demagnified image  90  is correlated with a URL (network information) by the analyzing unit  4 , and is stored in the image storage unit  9 . 
     Next, the case where the demagnified image  90  stored so as to be correlated with the URL is used to acquire and display information related to the image data from an information source  100  is described, based on FIGS. 12A,  12 B,  13 A, and  13 B. 
     When “OPEN THE SCRAPBOOK”  32  is selected, the demagnified image  90  stored in the image storage unit  9  is transferred to the display unit  6 , and the URL stored together with the demagnified image  90  is transferred to and analyzed in a data analyzing unit  4  before being transferred to the communication unit  3 . Subsequently, when latest (additional) data are received from the information source  100  corresponding to the URL, the received additional data are transferred to the data analyzing unit  4 . The data analyzing unit  4  analyzes the HTML, and issues text-displaying, image-drawing and graphics-displaying commands to the display unit  6  in accordance with the contents of the received data. The display unit  6  performs displaying in accordance with the commands from the data analyzing unit  4 , whereby new data from the information source  100  is displayed as shown in FIG.  11 A. 
     FIGS. 12A,  12 B,  13 A, and  13 B show examples of latest (additional) data, received from the information source  100 , which are displayed by the display unit  6 . FIGS. 12A and 12B show a display screen condition obtained when the scrapbook is open, where data cut out from a certain information source  100  is pasted. In this case, the contents of the displayed additional data shown in FIGS. 12A and 12B differ because, when the scrapbook is opened, the data of the information source  100  have changed. On the display screen, a plurality of demagnified images can be simultaneously displayed. 
     FIGS. 13A and 13B show data from an identical information source  100 . In this case, the contents of information change depending on timing for opening the scrapbook, similarly to the cases shown in FIGS. 12A and 12B. Accordingly, the contents on the display screen differ as shown in FIGS. 13A and 13B. 
     Next, one example of a programmed process for enabling the first and second embodiments of the present invention is described, based on the flowcharts shown in FIGS. 14 to  21 . This process enables the above-described first embodiment. 
     The flowchart shown in FIG. 14 is described. 
     In step S 1 , the window  20  is displayed. 
     In step S 2 , the inputting of coordinates from the coordinate input unit  5  is awaited. 
     In step S 3 , it is determined whether or not the coordinates are input. If the coordinates have been input, the process proceeds to step S 8 . If no coordinates have been input, key inputting from the key-input unit  1  is awaited in step S 4 , and in step S 5 , it is determined whether or not the key inputting has been performed. If no key inputting has been performed, the process returns to step S 2 , and key or coordinate inputting is awaited by repeatedly performing steps S 2  to S 5 . 
     In step S 5 , if key inputting has been performed, in step S 6 , it is determined whether or not the subwindow  40  is open. If the subwindow  40  is not open, the process returns to step S 2  since key inputting is not requested. If the subwindow  40  (FIG. 4) is open, the process proceeds to step S 7 , in which the input keys are displayed in the region  41  of the subwindow  40  before the process returns to step S 2 . 
     In step S 8 , it is determined whether or not the input coordinates represent a position on the menu command button  23 . If the input coordinates represent a position on the menu command button  23  (FIG.  5 ), the process proceeds to step S 32  shown in FIG.  18 A. If the input coordinates do not represent a position on the menu command button  23 , the process proceeds to step S 9 . 
     In step S 9 , it is determined whether or not the input coordinates represent a position on the menu command button  24 . If the input coordinates represent a position on the menu command button  24 , the process proceeds to step S 33  shown in FIG.  18 B. If the input coordinates do not represent a position on the menu command button  24 , the process proceeds to step S 10 . 
     In step S 10 , it is determined whether or not the input coordinates represent a position on the item  31  of the pull-down menu  30 . If the input coordinates represent a position on the item  31 , the process proceeds to step S 34  shown in FIG.  18 C. If the input coordinates do not represent a position on the item  31 , the process proceeds to step S 11 . 
     In step S 11 , it is determined whether or not the input coordinates represent a position on the item  32  of the pull-down menu  30 . If the input coordinates represent a position on the item  32 , the process proceeds to step S 26  shown in FIG.  17 . If the input coordinates do not represent a position on the item  32 , the process proceeds to step S 12 . 
     In step S 12 , it is determined whether or not the input coordinates represent a position on the item  33  of the pull-down menu  30 . If the input coordinates represent a position on the item  33 , the process proceeds to step S 35  shown in FIG.  18 D. If the input coordinates do not represent a position on the item  33 , the process proceeds to step S 13 . 
     In step S 13 , it is determined whether or not the input coordinates represent a position on the “CANCEL” button  42  in the subwindow  40 . If the input coordinates represent a position on the button  42 , the process proceeds to step S 36  shown in FIG.  18 E. If the input coordinates do not represent a position on the button  42 , the process proceeds to step S 14 . 
     In step S 14 , it is determined whether or not the input coordinates represent a position on the “OPEN” button  43  in the subwindow  40 . If the input coordinates represent a position on the button  43 , the process proceeds to step S 37  shown in FIG. 19A, in which the URL in the region  41  is extracted. If the input coordinates do not represent a position on the button  43 , the process proceeds to step S 15  shown in FIG.  15 . 
     In step S 15 , it is determined whether or not the input coordinates represent a position on the item  71  of the pull-down menu  70 . If the input coordinates represent a position on the item  71 , the process proceeds to step S 38  shown in FIG. 19B, in which the selected region is extracted. If the input coordinates do not represent a position on the item  71 , the process proceeds to step S 16 . 
     In step S 16 , it is determined whether or not the input coordinates represent a position on the item  72  of the pull-down menu  70 . If the input coordinates represent a position on the item  72 , the process proceeds to step S 39  shown in FIG. 19C, in which the extracted image data and URL are stored. If the input coordinates do not represent a position on the item  72 , the process proceeds to step S 17 . 
     In step S 17 , it is determined whether or not the input coordinates represent a position on the item  73  of the pull-down menu  70 . If the input coordinates represent a position on the item  73 , the process proceeds to step S 40  shown in FIG. 19D, in which the extracted image is demagnified. If the input coordinates do not represent a position on the item  73 , the process proceeds to step S 18 . 
     In step S 18 , it is determined whether or not the input coordinates represent a position on the item  74  of the pull-down menu  40 . If input coordinates represent a position on the item  74 , the process proceeds to step S 74  shown in FIG.  19 E, in which the entire region  21  is selected. If the input coordinates do not represent a position on the item  74 , the process proceeds to step S 19  shown in FIG.  16 . 
     In step S 19 , it is determined whether or not the input coordinates represent a position on the region  21  in the window  20 . If the input coordinates represent a position on the region  21 , the process proceeds to step S 20 . If the input coordinates do not represent a position on the region  21 , the process returns to step S 2  (FIG.  14 ). 
     In step S 20 , it is determined whether or not data are being displayed. If the data are being displayed, the process proceeds to step S 42  shown in FIG.  20 . 
     If the data are not being displayed, the process proceeds to step S 21 , in which it is determined whether or not the scrapbook is being displayed. If the scrapbook is not being displayed, the process returns to step S 2  since nothing is displayed in the window  20 . If the scrapbook is being displayed, the process proceeds to step S 22 , in which it is determined whether or not the input coordinates represent a position on the extracted image. If the input coordinates do not represent a position on the extracted image, the process returns to step S 2 . If the input coordinates represent a position on the extracted image, the process proceeds to step S 23 , in which the URL corresponding to the extracted image used for the determination in step S 22  is read from the image storage unit  9  as shown in step S 37  of FIG. 19A before the process proceeds to step S 24  shown in FIG.  21 . 
     In step S 24 , the URL obtained in step S 23  is used as a parameter to call a data-receiving routine shown in FIG.  21 . The routine shown in FIG. 21 comprises the steps of: issuing a data-receiving command to the information source  100  corresponding to the URL; analyzing the obtained data; and returning the result (described below). 
     In step S 25 , the data obtained in step S 24  is displayed in the window  20  before the process proceeds to step S 2 . 
     In steps S 26  to S 31  shown in FIG. 17, processing for opening the scrapbook is executed. 
     Initially, in step S 26 , the region  21  in the window  20  is cleared before the process proceeds to step S 27 . 
     In step S 27 , the URL stored in the image storage unit  9  is read. 
     In step S 28 , the URL obtained in step S 27  is used as a parameter to call the data-receiving routine. 
     In step S 29 , based on the data obtained in step S 28 , in accordance with conditions for extraction stored in the image storage unit  9 , partial image extraction or image demagnification is performed if necessary. 
     In step S 30 , the data processed in step S 29  are displayed in the window  20 . 
     In step S 31 , it is determined whether or not all the image data stored in the image storage unit  9  have been processed. If all the image data have not been processed, the process returns to step S 27 . If all the image data have been processed, the process returns to step S 2 . 
     In step S 32  (FIG.  18 A), the pull-down menu  30  is displayed before the process returns to step S 2 . 
     In step S 33  (FIG.  18 B), the pull-down menu  70  is displayed before the process returns to step S 2 . 
     In step S 34  (FIG.  18 C), the subwindow  40  is displayed before the process returns to step S 2 . 
     In step S 35  (FIG.  18 D), the window  20  is erased, and the programs terminate. 
     In step S 36  (FIG.  18 E), the subwindow  40  is erased before the process returns to step S 2 . 
     As shown in FIGS. 19A to  19 E, in step S 37 , the URL input in the region  41  is fetched before the process returns to step S 4 . 
     In step S 38 , the selected region is extracted by the image extracting unit  7  before the process returns to step S 2 . 
     In step S 39 , the extracted image, conditions used in the extraction, and the URL are stored before the process returns to step S 2 . 
     In step S 40 , the extracted image is demagnified by the image demagnifying unit  8 . 
     In step S 41 , the whole of the region  21  is selected before the process returns to step S 2 . 
     As shown in FIG. 20, in step S 42 , it is determined whether or not a first coordinate point is being selected. If the first coordinate point is not being selected, in step S 42 , the input coordinates are used as the first point, and the process returns to step S 2 . If the first coordinate point is being selected, the process proceeds to step S 43 , in which it is determined whether or not a second coordinate point is being selected. If the second point is not being selected, in step S 47 , the input coordinates are used as the second coordinate point, and the process proceeds to step S 45 . If the second coordinate point is being selected, the process proceeds to step S 44 , in which the second coordinate point being selected and the selected region are canceled before the process proceeds to step S 45 . 
     In step S 45 , a rectangular region formed by two line segments orthogonally crossing at the first coordinate point and two line segments orthogonally crossing at the second coordinate point is used as a selected region, and the process returns to step S 2 . 
     The data-receiving routine, shown in FIG. 21, is a subroutine that comprises the steps of: receiving a URL as a parameter; issuing a data-receiving command to the information source  100  corresponding to the URL; analyzing the obtained data; and returning the result. 
     Initially, in step S 101 , the URL is evaluated by the data analyzing unit  4  before the process proceeds to step S 102 . 
     In step S 102 , the communication unit  3  is used to issue a data-obtaining command to the information source  100  corresponding to the URL before the process proceeds to step S 103 . 
     In step S 103 , the communication unit  3  is used to receive data from the information source  100 . 
     In step S 104 , the data obtained in step S 103  are analyzed by the data analyzing unit  4 , and are used as return data before the process returns. 
     According to the foregoing embodiments, a data analyzing means is used to correlate image data with network information (address) before the image data are stored in a storage means, and the stored image data is designated, whereby the network information corresponding to the designated image data is read and analyzed in a data analyzing means, so that data received from the information apparatus corresponding to the network information are displayed by a display means. Therefore, information from the information apparatus is visually recognized by implementing simple processing, whereby target information (homepage) is easily obtained. 
     According to the foregoing embodiments, extracted image data and network information (address) are stored so that they are correlated with each other before the data are reduced, whereby a large amount of image data can be stored, and a plurality of data can be simultaneously displayed since the reduced image data occupies a small area. Therefore, operation efficiency is improved.
