An article retrieval system for a computer having an article storage storing an article and an article attribution storage storing attribution data of an article image corresponding to the article, said article retrieval system comprising:
a decision unit determining a suitable method of miniaturizing the article image based upon the attribution data of the article image; and a display processor generating a miniature image of the article image based upon the method determined by the decision unit.
The present invention relates to an article retrieval support apparatus such as a personal computer for supporting retrieval of articles when making reference to articles which have been posted to a network such as the Internet, and the present invention also relates to a recording medium which can be read by the article retrieval support apparatus.
Communication systems have become popular to exchange opinions with numerous people in which they make reference to or post an article from a personal computer which is connected to a network such as the Internet or personal computer network. When the number of associated people and thus the number of articles increase in such a communication system, it becomes difficult to retrieve an article which the user would like to make reference to.
With this point in mind, it has been proposed for an apparatus which comprises a function of supporting retrieval of articles by displaying on the screen a list of identification data of articles which may be miniature image of contents of an article or of images attached to an article.
However, although the conventional apparatus comprising such a function as to display the list of identification data provides the user a retrieval supporting function to make him or her intuitively understand the content of the article by the identification data which may be a figure or a miniature image, the number of articles that the user is able to retrieve through confirming each of the figures or miniature images with his or her own eyes is limited. Therefore, the retrieval supporting function does not work effectively when the number of articles is enormous.
Further, when generating miniature images as identification data of articles, there are different methods for obtaining clear miniature images, depending on whether the original image is a binary image such as a text, or a color image such as a bit map, and in case of a color image, it depends on whether a large number of colors are used or only a small number (e.g. an image written with a pencil). However, since the miniaturizing method of an image is selected by the user in such a conventional apparatus, it presents a drawback in that beginners or children having no knowledge of image processing may not be able to select a most suitable miniaturizing method.
The present invention has been made in view of these drawbacks, and it is an object of the present invention to provide an article retrieval support apparatus such as a personal computer which is capable of limiting the number of identification data of articles among which retrieval is to be executed through displaying images of the identification data of the articles at varied transparency rates or miniaturizing rates corresponding to the novelty of the article or attribute data of the article such as repute of the article, and it is also an object of the present invention to provide a recording medium which can be read by the article retrieval supporting apparatus.
It is further an object of the present invention to provide an article retrieval support apparatus such as a personal computer which can be easily used also by beginners or children having no knowledge of image processing wherein a most suitable miniaturizing method is automatically selected according to the original image when generating a miniature image of identification data of the article, and it is also an object of the present invention to provide a recording medium which can be read by the article retrieval supporting apparatus.
According to the present invention, it is automatically determined how a miniature image is to be generated, depending on the type of an image of an article (e.g. text, bitmap, number of colors, etc.), by either of the following methods. In the first method, an average value of pixel values of each divided image portion of an image of an article, divided according to a miniaturizing rate, is calculated in accordance with reducing rates, and a miniature image which is composed of a gathering of these averaged pixels is generated. An edge of the obtained miniature image is then detected where a gray level greatly changes, and by emphasizing and sharpening the edge, a miniature image is generated. For generating a miniature image according to the second method, it is performed, in addition to the above steps, a step of transforming a gray level of each pixel of the miniature image into a gray level by which the contrast of the miniature image is emphasized. A miniature image is generated in the third method by performing OR operation of pixel values of neighboring pixels of an image showing the content of an article.
Therefore, the apparatus according to the present invention can be easily used also by beginners or children having no knowledge of image processing.
Further, according to the present invention, a transparency rate of an image of identification data of an article is varied relative to a background thereof proportional to the length of an elapsed time from the time at which the article is posted, so that, for instance, an image of identification data of an article is displayed at a higher transparency rate for which the elapsed time from the time of the posting is longer.
Further, according to the present invention, the miniaturizing rate of an image of identification data of an article is varied proportional to the length of an elapsed time from the time at which the article is posted, so that, for instance, an image of identification data of an article is displayed smaller for which the elapsed time from the time of the posting is longer.
Further, according to the present invention, repute data indicating a height of a repute of an article is obtained from an article server, and though no images of identification data of articles are displayed for which a specified time has elapsed since they are posted, an image of identification data of an article with high repute is made to be displayed for a longer time than images of identification data of other articles by shortening the elapsed time of the articles of the high repute.
Further, according to the present invention, repute data, which may be the number of readers or the number of votes, indicating a height of a repute of the article is obtained from an article server, and identification data of articles of high repute (i.e., which the number of readers or votes exceed a specified number) are displayed in different display styles from the style of identification data of other articles by, for instance, changing the color, magnifying the image or applying a repute mark thereto.
Further, according to the present invention, when a specified figure such as a cursor figure which moves over a screen has passed over an image of identification data, an image of addition data indicating an attribution of the article (e.g. writer of the article, date of posting, etc.) is displayed in the proximity of the image of the identification data.
Further, according to the present invention, there are only displayed images representing identification data of articles which agree a display condition such as the displayable number on the screen or a term for display.
Consequently, the number of identification data of articles among which retrieval is to be executed may be limited.

FIG. 1 is a block diagram showing embodiment 1 of a personal computer which is employed as the article retrieval support apparatus according to the present invention.
An information substance storage 10 stores the substance of articles. An attribution storage 20 stores in an attribution table thereof attribution data of the substance of the article substances which are at least (1) a display position (coordinate data) which was designated by the user by a position designating means such as a mouse in order to paste a miniature image or icon which is identification data of an article; (2) a display form of identification data (a miniature image or fixed bitmap data such as icon); (3) size of the original image for generating a miniature image (height�width); (4) the number of colors used in the original image; (5) the storage address of the original image; (6) a file name which is an identifier of an article and included in a header thereof (aaa.bmp, bbb.txt); or (7) the storage address of the article substance.
FIG. 2 is a conceptual diagram of such an attribution table.
A processing data storage 30 stores data for processing an image substance to generate a miniature image. In this embodiment, a miniaturizing rate for obtaining a miniature image from the original image or size of a miniature image (the number of pixels in height�width) is stored. It should be noted that the miniaturizing rate or size is set by the user.
A display processing part 40 generates a miniature image from an original image in a miniature image generation part 401 in case the display form of the identification data of the article substance is “miniature image”.
The miniature image generation part 401 comprises, as generating means of a miniature image, an averaged image generation part 4011 for setting an averaged value of pixel values of object pixels of the original image (for instance, if reduced to half in length, four neighboring pixels) as a pixel value for one pixel; a sharpening operation part 4012 for detecting an edge of the image and emphasizing (sharpening) the edge; a gray level transform operation part 4013 for transforming a gray level of each pixel of the image into a gray level at which the contrast is emphasized; and an OR operation part 4014 for performing an OR operation of object pixels of the original image according to the miniaturizing rate and leaving black pixels.
A miniaturizing method decision part 4015 makes a most suitable generation means operate among the above-described generation means for generating a miniature image which sufficiently represents characteristics of the original image and which is also clear on referring to the attribution table of the attribution storage 20 and generates a miniature image based on data such as whether the original image is a text or a bitmap (which may be determined from the file name) or whether the number of colors is large or small in case the image is a bitmap.
A display unit 50 displays the miniature image which has been generated in the display processing part 40 on a portion of a display depending on the coordinate data in the attribution table.
It will be next explained for a method of selecting a miniaturizing method according to the attribution of the original image.
There are known several methods for generating miniature images such as (1) thinning out, (2) averaging (by the area), or (3) performing an OR operation (in case of a binary image). However, the effective method is limited depending on the characteristics of the image. For instance, while “thinning out” is effective for natural color images such as landscapes, it is not suitable for images of few colors or images of characters written with a pencil, since data will vanish.
Further, while an “averaging” method may be employed for a variety of images, images will oftentimes fade. “Performing an OR operation” can only be applied to binary images.
Therefore, according to characteristics of the original image which may be
number of colors (actually used ) in the image
monochrome or colored,
either “averaging+sharpening” is selected when the image is a color image and the number of colors is quite large; “averaging+sharpening+gray level transformation” when it is a color image but containing only a small number of colors such as an image of a pencil drawing in order to make a color difference for clarification, since “averaging+sharpening” is not sufficient to eliminate a dim impression, and “OR operation” is performed in case the image is a text image or a binary image.
FIG. 3 is a diagram showing an example of a screen display of a miniature image.
The miniature image as processed and generated as explained above is stored in a memory (not shown) of the miniature image generation part 401 and the storage address thereof is entered in the table of a display information storage 90 of FIG. 1.
It should be noted that while this embodiment has been explained by referring to a case in which the miniature image is of a rectangular shape, the shape of the miniature image is not limited to such a rectangular shape.
FIG. 4 is a block diagram showing embodiment 2 of a personal computer which is employed as the article retrieval support apparatus according to the present invention. It should be noted that portions which are identical with or equivalent to those of embodiment 1 are marked with the same reference numerals and explanations thereof will be partially deleted.
In this embodiment, when displaying identification data of articles as in FIG. 3 (which are miniature images in FIG. 3), identification data of older articles are displayed to be more transparent than those of newer ones.
For this purpose, the present embodiment is arranged to comprise a clock 60 for providing the display processing part 40 with the present time, wherein a processing data storage 30 stores miniaturizing rates or sizes which are supplied to a miniature image generation part 401 together with transparency rates which correspond to elapsed times that are stored in a table thereof (see FIG. 5), and a display information storage 90 stores in an attribution table thereof dates on which articles were posted.
Further, the display processing part 40 comprises an elapsed-time calculation part 402 for calculating the elapsed time from the time obtained from the attribution table at which the article was posted up to the present time given by the clock 60, and a show-through image generation part 403 for generating a miniature image of a transparency rate corresponding to the elapsed time obtained from the table of the processing data storage 30 from the miniature image generated by the miniature image generation part 401.
It should be noted that the miniature image generation part 401 stores the generated miniature image in a memory (not shown) and the storage address thereof is entered in the table of the display information storage 90.
The show-through image generation part 403 generates a show-through image by performing the following calculation for all of the pixels of the miniature images generated by the miniature image generation part 401.
TP(x, y)=P(x, y)�(1−TRNSP)+BP(x′, y′)�TRNSP TRNSP: transparency rate
P(x, y): pixel value at position (x, y) of miniature image
BP(x, y): pixel value at coordinate (x, y) of background image (coordinate corresponding to position (x, y))
TP(x, y): generated transparent pixel value at position (x, y)
It should be noted that the transparency rate is 0 or more and 1 or less.
The display processing part 40 outputs the thus generated show-through image to the display unit 50 together with the coordinate data of the display position. However, in case the transparency rate is 1, no miniature image is displayed so that no data is output to the display unit 50.
FIG. 6 is a block diagram showing a modified example of embodiment 2. It should be noted that portions identical with or equivalent to those of embodiment 2 are marked with the same reference numerals and explanations thereof will be deleted.
In this modified example, there is no table provided for transparency rates in a processing data storage 30, and instead, the storage stores increases in transparency rates for each elapsed time such as “increasing the transparency rate by Y % for each additional time X”.
In a display processing unit 40, a transparency rate calculation part 404 provides a show-through image generation part 403 with a transparency rate corresponding to an elapsed time calculated by an elapsed-time calculation part 402 based on the increase of transparency rate given by the processing data storage 30. The show-through image generation part 403 performs the above-described calculation and generates a show-through image of a transparency rate corresponding to the elapsed time then outputs the image to a display unit 50 together with the coordinate data of the display position thereof. However, in case the transparency rate is 1, no miniature image is displayed so that no date is output to the display unit 50.
FIG. 7 is a block diagram showing embodiment 3 of a personal computer which is employed as the article retrieval support apparatus according to the present invention. It should be noted that portions which are identical with or equivalent to those of embodiment 1 are marked with the same reference numerals and explanations thereof will be partially deleted.
In this embodiment, when displaying identification data of articles as in FIG. 3 (which are miniature images in FIG. 3), identification data of older articles are displayed to be smaller than those of newer ones.
For this purpose, the present embodiment is arranged to comprise a clock 60 for providing a display processing part 40 with the present time, wherein a processing data storage 30 stores miniaturizing rates or sizes which are supplied to a miniature image generation part 401 together with miniaturizing rates which correspond to elapsed times that are stored in a table thereof (see FIG. 8), and a display information storage 90 stores in an attribution table thereof dates on which articles were posted.
Further, the display processing part 40 comprises an elapsed-time calculation part 402 for calculating the elapsed time from the time obtained from the attribution table at which the article was posted up to the present time given by the clock 60 and a miniature image generation part 401 for generating a miniature image miniaturized at a rate calculated by multiplying the miniaturizing rate of the original image obtained from the table of the processing data storage 30 by the miniaturizing rate corresponding to the elapsed time. The miniature image generation part 401 outputs the generated miniature image to a display unit 50 together with the coordinate data of the display position thereof. However, in case the miniaturizing rate is 0%, no miniature image is displayed so that no date is output to the display unit 50.
The miniature image generation part 401 stores the above-mentioned miniature image in a memory (not shown) and a storage address thereof is registered in the table of the display information storage 90.
FIG. 9 is a block diagram showing embodiment 4 of a personal computer which is employed as the article retrieval support apparatus according to the present invention. It should be noted that portions that are identical with or equivalent to those of embodiment 1 are marked with the same reference numerals and explanations thereof will be partially deleted.
An article server 2 transfers articles posted from plural personal computers which are clients to personal computers which have accessed thereto, while obtaining and storing repute data such as the number of readers or votes in favor, and provides the repute data to personal computers requiring such repute data of the articles. In this embodiment, a personal computer 1 is connected as a client to the article server 2.
Further, the personal computer 1 according to this embodiment has a function to limits the number of objects to be retrieved by eliminating identification data of articles for which a specified time has been elapsed since the time of posting by, for instance, deleting the eliminated identification date from a memory of a miniature image generation part 401.The personal computer 1 also has a function to seemingly shorten the elapsed time for an article of high repute in order to display the identification data thereof as long as possible.
The miniature image generation part 401 stores the generated miniature image in a memory (not shown), and a storage address thereof is entered in a table of a display information storage 90.
For this purpose, the present embodiment is arranged to comprise a clock 60 for providing a display processing part 40 with the present time, and an attribution storage 20 stores the date of posting of the article in an attribution table. An article receiving part 70 stores the information substance received from the article server 2 in an information substance storage 10 and attribution data in the attribution storage 20. The article receiving part 70 receives repute data such as the number of readers or votes upon transmitting a command requesting for repute data which is output from an elapsed-time compensation part 405 to the article server 2, and transfers the repute data to an elapsed-time compensation part 405.
Based on an identifier of an article included in the header of the article, the elapsed time compensation part 405 requests the article server 2 for repute data through the article receiving part 70, obtains the number of readers and votes from the article server 2. The elapsed time compensation part 405 shortens the elapsed time calculated by an elapsed-time calculation part 402 for a specified period or by a specified reduction rate if either the number of readers or votes exceeds a specified number.
An image processing operation part 406 obtains a transparency rate, miniaturizing rate, or a transparency rate and a miniaturizing rate, corresponding to the elapsed time compensated by the elapsed-time compensation part 405, and generates a miniature image miniaturized at a rate calculated by multiplying the miniaturizing rate of original image obtained from the table of the processing data storage 30 by the miniaturizing rate corresponding to the elapsed time. The image processing operation part 406 further transforms the generated miniature image into a miniature image of a transparency rate corresponding to the elapsed time, and outputs this miniature image to a display unit 50 together with the coordinate data of the display position thereof.
FIG. 10 is a block diagram showing a modified example of embodiment 4. It should be noted that portions that are identical with or equivalent to those of embodiment 4 are marked with the same reference numerals and explanations thereof will be deleted.
In this modified example, the elapsed-time calculation part 402, the elapsed-time compensation part 405, and the image processing operation part 406 of embodiment 4 are replaced by a repute data addition part 80 for making displays for identification data of an article of high repute attract attention by, for instance, changing the display color for identification data of an article of high repute, which is the number of readers or votes exceeding a specified number or applying a mark to the identification data indicating high repute.
Based on an identifier of an article included in the header of the article, the repute data addition part 80 requests an article server 2 for repute data through an article receiving part 70, obtains the number of readers and votes from the article server 2. A display addition part 803 changes the display color for identification data, which may be a miniature image processed and generated by a display processing part 40, into a color different from colors for other identification data, and attaches a mark indicating high repute to the identification data, when it is either determined by a number-of-readers judgement part 801 that the number of readers exceeds a specified number or it is determined by a voting result judgement part 802 that the number of votes exceeds a specified number.
