An electronic catalog system that can reduce manufacturing costs has been put to practical use.

By the way, in order to reproduce a CD-ROM, a special player connected to a personal computer is usually required, but a home-use television set can also be used as a monitor. In general, mail-order companies often employ a system of lending a dedicated system that can be connected to a home television set for customers who do not own a personal computer. In such a system, the user normally displays the product information on the monitor of his or her home television set, unlike a conventional catalog in which a photo of the product and various information about it are printed on paper. To use.

On the other hand, in recent years, a television set having a relatively large screen of 25 inches or more has become popular for home use, and a so-called wide television is used instead of the conventional screen size with an aspect ratio of 4: 3. Television sets with a screen aspect size of 28 inches or 32 inches or more, which is called horizontal aspect ratio of 15: 9, are also popular. In such a monitor of a television set having a relatively large screen, for example, tableware, etc.
It is possible to display the absolute size of daily necessities etc. on the screen at the original size. Therefore, there is an advantage that even a product that could not be displayed in full size in the conventional catalog of printed materials of about A4 size can be displayed in full size on a monitor with a large screen.

The present invention has been made in view of the above circumstances, and when the image of a product is displayed, the size of the product referred to on the screen by the user is increased by enlarging / reducing the image data. It is an object of the present invention to provide an electronic catalog system in which the difference between the product size and the actual product size is reduced, and the product image on the screen gives a more realistic feeling.

Further, when displaying an image of a product, by enlarging / reducing the image data corresponding to the monitor size, the size of the product referred to by the user on the screen and the size of the actual product are displayed. The purpose of the present invention is to provide an electronic catalog system in which the difference between items is reduced and the product image on the screen gives a more realistic feeling.

Further, when displaying an image of a product, the absolute display size corresponding to the monitor size is displayed as the original size of the product, so that the size of the product referred to by the user on the screen and the actual size It is an object of the present invention to provide an electronic catalog system in which the size of the product is matched and the product image on the screen is substantially the same as the actual product.

Furthermore, when the image of the product is displayed, the scale ruler corresponding to the enlargement / reduction ratio of the image data of the product is also displayed near the image of the product, so that the user can display the actual size of the product. The purpose of the present invention is to provide an electronic catalog system capable of making the above judgment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing the embodiments thereof. FIG. 1 is a schematic diagram showing an example of the overall configuration of the electronic catalog system of the present invention.

In FIG. 1, reference numeral 8 indicates a computer of a mail order dealer, which is connected to a public line 6 via a modem 7. Also connected to this public line 6 are many consumer modems 5 (only one consumer's modem is shown in FIG. 1). The dealer's computer 8 is connected to a database of customer information and product information (customer database 81, product database 82).

At the center of the electronic catalog system of the present invention is the CD-ROM player 1 on the consumer side, which sends and receives data to and from the modem 5, and thus to and from the computer 8 of the trader. It is possible. The CD-ROM player 1 is loaded with, for example, a CD-ROM 10 as an electronic catalog sent from a vendor once a month or every four seasons and played.

An input device 3 such as a keyboard, a mouse or a control pad is connected to the CD-ROM player 1 so that an instruction for reproducing the CD-ROM 10, a screen change, an instruction for ordering, etc. can be performed. CD-ROM player 1
A monitor 2 for displaying read information from the CD-ROM 10 or input information from the input device 3 and the like, and a printer 4 for printing order information are connected.

The monitor 2 may be a monitor attached to a so-called personal computer system.
It is also possible to use the monitor of a general home television set. In other words, the consumer system described above can use the personal computer system equipped with the CD-ROM 10 as it is if the consumer owns it. When the consumer does not own the television set, the vendor generally lends a dedicated system that can use the television set owned by the consumer as the monitor 2. Although a dedicated system lent by such a vendor basically has a function as a personal computer system, it is a system that can only play a CD-ROM as an electronic catalog supplied by the vendor. is there. In the following embodiments, a monitor of a consumer's home television set is used as the monitor 2.

FIG. 2 is a block diagram showing an example of the structure of the CD-ROM player 1. The MPU 11 is a control center of the player 1 and a ROM 12 storing a basic operating system (OS) including a control program of the CD-ROM player 1, a RAM used as a working memory 13, a system such as ordering information and the like. Input control, which is an interface between the non-volatile memory 14 used to store information that should be retained even after the power of the computer is cut off, the auxiliary storage control device 19 that controls the CD-ROM playback device 18, and the input device 3. A device 15, an output control device 16 which is an interface of the printer 4, a communication control device 17 for controlling transmission / reception with the modem 5, a video memory 20 for storing image information to be displayed on the monitor 2, and audio information. Audio buffer 21, Enlargement / reduction circuit for enlarging / reducing image data to be displayed on monitor 2.
It is connected to the bus with 24, and it is possible to send and receive data between them.

Further, reference numeral 25 is a scale ruler circuit, which enlarges / reduces the image data of the scale ruler in accordance with the enlargement / reduction ratio given from the enlargement / reduction circuit 24 when instructed by the MPU 11. Output. The image data of the scale ruler output from the scale ruler circuit 25 is overwritten on the position specified by the MPU 11 of the video memory 20. Therefore, when such image data of the video memory 20 is displayed on the monitor 2, the image of the scale ruler is superimposed on the image of the product.

In addition, the video D / A converter 22 converts digital data in the video memory 20 into analog data when it is supplied to the monitor 2, and the voice D / A converter 23 in the voice buffer 21. When the digital data is given to the monitor 2, it is converted into analog data.

The CD-ROM 10 is, of course, similar to the conventional CD-ROM of this type, in which image data of individual products and various data necessary for searching for individual products are recorded. As will be described later, in order to determine the display magnification when displaying the image data of the product on the screen by the optimized display function that is a feature of the present invention, the actual size of each image data of the individual product is determined. The data (hereinafter referred to as the size coefficient) regarding the data is also recorded.

Next, regarding the operation of the electronic catalog system of the present invention, the flowcharts divided into FIGS. 3 and 4 showing the processing procedure by the MPU 11 and the display state on the display screen of the monitor 2 are shown. This will be described with reference to the schematic diagram.

When the CD-ROM 10 is set in the CD-ROM player 1 (step S11), the MPU 11 reads the OS (operating system) program for controlling the CD-ROM player 1 from the ROM 12 and executes it. To do. When the OS is executed, the application program previously recorded in the CD-ROM 10 is read and stored in the RAM 13.
The above is the operation procedure at the time of startup in a general computer system, that is, the startup process (step S12).

Next, the MPU 11 starts executing the application program transferred from the CD-ROM 10 to the RAM 13.
First, the screen of the "screen size setting menu" for selecting the size of the monitor to be used is displayed on the monitor 2.
(Step S13). In the following description, various instructions from the user are executed by clicking the display on the screen of the monitor 2 with the mouse serving as the input device 3.

FIG. 5 is a schematic diagram of the screen 100 of the "screen size setting menu" described above. In this screen 100, reference numeral 101 is a group of buttons for selecting the screen size of a normal television monitor having a screen aspect ratio of 4: 3, and in this example, it is an unspecified button from a minimum of 10 inches to a maximum of 33 inches. 111 and are prepared in advance. Further, reference numeral 102 is a so-called wide television monitor screen size selection button group, and in this example, a minimum of 15 inches to a maximum of 36 inches and an undesignated button 112 are prepared in advance. The method of using the unspecified button will be described later.

The user selects the screen size of the monitor 2 by clicking one of the numbers displayed on the button groups 101 and 102. For example, if the user clicks on a 25-inch button on a regular television monitor, as indicated by reference numeral 103,
The user is informed that only that portion is currently selected, for example, with high brightness. At the same time, as indicated by reference numeral 104, the currently selected screen size and format (4: 3 screen or wide screen) are displayed.

As indicated by reference numeral 105, it is also possible to use the "Small" or "Large" button to sequentially change the display of the screen size for selection.
Alternatively, it is possible to specify a size not prepared for the screen 100. Further, as indicated by reference numeral 106, it is possible to select either one by using the "4: 3" or "Wide" button.

Reference numeral 107 is a button that the user clicks when the user finishes setting the screen size. When this button is clicked, the user can actually browse the catalog. Further, before the user clicks the setting end button 107, the selection of the screen size can be changed. In other words,
When the user clicks the setting end button 107, it is set whether or not the user uses the optimized display function, which is a feature of the present invention (step S14).

The selection of the monitor size as described above is performed by the electronic catalog system of the present invention in which the display magnification is changed in accordance with the screen size when the user views the image of the product on the screen of the monitor 2. This is an operation necessary to effectively use the characteristic function, that is, the optimized display function. However, in this case, if an image of a product with a large size is displayed with a small screen size, the entire product may not be displayed. In order to avoid such a situation, the electronic catalog system of the present invention can perform the same display as the conventional electronic catalog system.

For example, on the "screen size setting menu" screen 100 shown in FIG. 5, the user selects an unspecified button 111 of the screen size selection button group 101 or 102.
Or, if 112 is clicked, as shown in the schematic view of FIG. 6, those buttons 111 and 112 become, for example, high brightness, and the optimized display function which is a characteristic function of the electronic catalog system of the present invention is displayed. Settings that are not used are made. When the setting for not using the optimized display function is made in this way, "0" is set to the parameter "MEM1" (step S15). As a result, when the image data is displayed, neither enlargement nor reduction is performed, and the image data is displayed in the default display size. Specifically, as shown in the schematic view of FIG. 7, a small monitor screen 300S,
Images are displayed in a size proportional to the screen size on both the screen 300M of the medium-sized monitor and the screen 300L of the large-sized monitor.

When the optimization display function is not used in step S14, the parameter "MEM1" is set to "0" in step S15 as described above, but the optimization display function is used. If the above is performed, the monitor size is set by the user as described above (step S16), and the value S of the size is substituted for the parameter "MEM1" (step S17).

In the case where the product is displayed in the original size by using the optimized display function of the electronic catalog system of the present invention, as described above, when the product having a large size is displayed with a small screen size, the whole product may not be displayed. is there. In preparation for such a situation, as shown in the schematic diagram of FIG.
"Display method setting menu" for selecting the display method
Screen 201 is prepared. Whether the image data of all the products stored in the CD-ROM 10 can be displayed in full size on the monitor of the size selected earlier is determined by the size stored with the image data of each product. Since the coefficient α can be easily found by the MPU 11 examining it (step S18),
If the selected monitor size has image data of a product that cannot be displayed at the actual size, the "display method setting menu" screen 201 is displayed (step S19).

As shown in FIG. 8, in the "display method setting menu" screen 201, only the products which can be displayed in the actual size are displayed in the actual size, or the products which cannot be displayed in the actual size are displayed in the actual size. Then, a button group 202 for allowing the user to select from the three options of scroll display or normal display of all products as in the past is displayed.

When the user selects any one of these and clicks it, and further clicks the setting end button 107, if only the product that can be displayed in the actual size is selected to be displayed in the actual size (step S20), a flag " If "MEM2" is set to "1" (step S23) and the product itself that cannot be displayed in full size is displayed in full size and scroll display is selected (step S21), "MEM2" is set to "0". ”
Is set to (step S24), and all the products are selected to be displayed as usual (step S2).
In 2), the variable "MEM1" is set to "0" in step S15.

When normally displayed in the schematic view of FIG. 9,
That is, the display state when full-scale display cannot be performed and the display state when scroll display is performed are shown in the schematic diagram of FIG. In FIG. 9, the image 301 of the product is larger than the size of the monitor screen 300, so that the absolute size on the monitor screen 300 is displayed in a reduced state, and is indicated by reference numeral 303. A scale ruler like this is also displayed. By displaying such a scale ruler, the user can know the actual size of the product. Also, FIG.
Then, the image 302 of the product itself is displayed in the absolute size on the monitor screen 300 in its original size, and the user can view the whole by instructing scrolling.

With the above, the setting of the optimized display function in the electronic catalog system of the present invention is completed. If you choose not to use this optimized display function, the variable is
If "MEM1" is set to "0" and the optimization display function is selected, the value of the monitor size in inches is assigned to the variable "MEM1". Furthermore, the optimization display function is used. If the selection is made to display only the products that can be displayed at the actual size in the actual size, the flag "ME" is displayed.
If the item M2 "is set to" 1 "and the product that cannot be displayed in the actual size is displayed in the actual size and scroll display is selected," MEM2 "is set to" 0 ".

As described above, in the electronic catalog system of the present invention, after the user makes various settings regarding the screen display for the optimized display function, the product is introduced in the same manner as the conventional general electronic catalog system. Therefore, you can apply for purchase. However, as described above, a user who dislikes such an operation as complicated is a user who does not specify the screen size selection button group 101 or 102 on the “screen size setting menu” screen 100 shown in FIG. If the optimization display function is not selected by immediately clicking the button 111 or 112, it is possible to immediately introduce the product, apply for purchase, etc., as in the case of the conventional general electronic catalog system. Of course, in this case, the image of each product is not displayed in the actual size.
As shown in the schematic diagram of a small monitor screen 300
An image is displayed in a size proportional to the screen size on any of the S, medium-sized monitor screen 300M, and large-sized monitor screen 300L.

Now, various screen display states by the optimized display function of the electronic catalog system of the present invention will be described.

FIG. 11 is a schematic view showing a state in which the same image is displayed in its original size on monitors of three sizes.
An image that can be displayed at its original size on a relatively small (for example, 14-inch) monitor screen 400S is also displayed at its original size on a medium-sized (for example, 25-inch) monitor screen 400M.
It is also displayed in its original size on the monitor screen 400L (29 inches), and the scale ruler 402 is also displayed for each. However, the character information 403 such as image description and price is displayed in a size proportional to the size of each monitor screen 400S, 400M, 400L.

FIG. 12 and FIG. 13 are also schematic diagrams showing the same image displayed in full size on monitors of three sizes. However, in the example shown in Fig.12 and Fig.13, the image that can be displayed at full size on a medium-sized (for example, 25 inch) monitor 400M is relatively large (for example, 29 inch).
Although it is displayed on the monitor 400L in its original size, it is possible to display it in its original size on the relatively small monitor 400S. Therefore, in the example shown in FIG. 12, the monitor 40 having a relatively small size is used.
For 0S, scroll display is selected and the image itself is displayed at full size. Therefore, in the example shown in FIG. 12, the relatively small monitor 400S allows the user to scroll the entire image and view it in its original size by giving a scroll instruction.

On the other hand, in the example shown in FIG. 13, the normal display is selected for the relatively small monitor 400S, and the image itself is displayed in the so-called default size.
Therefore, although the monitor 400S, which is relatively small, does not display the original size, the user can view the entire image without scrolling.

Next, regarding the operation procedure of the electronic catalog system of the present invention, the above-mentioned schematic diagrams showing various screen display states by the optimization display function and the flowchart divided into FIG. 14 and FIG. 15 are shown. It will be described with reference to FIG.

When it is determined whether or not to use the optimized display function as shown in the flowcharts divided and shown in FIGS. 3 and 4 (step S51),
A path for reading image data from the CD-ROM 10 is set (step S52). As a result, the background, buttons, etc. are first displayed on the monitor 2 (step S53), and then it is determined which product image data is to be displayed (step S5).
Four). Although the details of the processing in step S54 are omitted, similar to a normal electronic catalog system, for example, whether the images of the products are displayed one by one in a predetermined order (in the image of sequentially turning the pages of the printing catalog) Alternatively, when the user inputs a keyword such as “tea cup”, the image of the related product is displayed.

For example, assume that an image of a tea cup and a pot as shown in FIG. 9 is displayed. In this case, the image data and the size coefficient α attached to it are read out from the previously set path and once
20 and RAM 13 (step S55), and then it is checked whether or not the optimization display function is selected (step S55).
S56). Of course, in the processing of step S56, the variable "MEM1" is
It is to check whether it is "0".

When the optimized display function is not used, that is, when the variable "MEM1" is "0", the image data is immediately displayed on the monitor 2 in the default size of the image data (step S57). Specifically, video memory
The image data stored in 20 is the D / A for video as it is.
It is displayed on the monitor 2 via the converter 22. This state is shown in the schematic diagram of FIG. 9, and the absolute size is displayed in a reduced size rather than the actual size.

On the other hand, when the optimized display function is used,
That is, when the variable "MEM1" is not "1", the currently set monitor size S is stored as the parameter "MEM1". Is checked (step S101)
. If full-scale display is possible, MPU 11 will use the parameter “MEM
The enlargement / reduction ratio is calculated from the relationship between the monitor size value S stored as 1 ”and the image data size coefficient α.
(Step S102), Enlarging / Reducing Circuit from Video Memory 20
The image data is sent to 24 to be enlarged (or reduced) (step S103), and the resulting image data is stored in the video memory 20 again. At the same time, the MPU 11 gives an instruction to the scale ruler circuit 25 to generate image data of the scale ruler according to the enlargement / reduction ratio calculated by the enlargement / reduction circuit 24, and overwrites the image data on a predetermined position of the video memory 20. After that, the image data of the video memory 20 is displayed on the monitor 2 (step S57).

When it is determined in step S101 that the full-scale display is impossible, the value of the flag "MEM2" is checked (step S111). If the value of the flag "MEM2" is not "0", in other words, if it is "1", it is selected to perform normal display when full-scale display is not possible. 20 to monitor 2
Sent to and displayed (step S57). In this case, MP
U 11 gives an instruction to the scale ruler circuit 25 to calculate the scaling ratio of the scale ruler from the relationship between the monitor size value S stored as the parameter “MEM1” and the image data size coefficient α. Image data of a scale ruler is generated according to the enlargement / reduction ratio, and the image data is overwritten on a predetermined position of the video memory 20. After this, the image data of the video memory 20 is displayed on the monitor 2.

However, if the value of the flag "MEM2" is "0", the MPU 11 calculates the enlargement / reduction ratio because the original size is selected by the scroll display (step S102), and the enlargement / reduction is performed. The image data is sent from the video memory 20 to the reduction circuit 24 to be transformed (enlarged or reduced) (step S103), and the resulting image data is stored in the video memory 20 and displayed on the monitor 2 (step S57). ).
In this case, the scale ruler is displayed in the same manner as the above-mentioned full-scale display.

The image of the product thus obtained is displayed on the monitor 2
The user decides whether or not to select / search for another product in the state displayed in (step S58). When the user performs a process for selecting / searching for another product by a predetermined operation (step S59), the MPU 11 returns the process to step S54, and the user determines the product to be displayed next. To do.

In step S58, when the user does not select / search for another product, it is determined whether or not to purchase the product displayed at that time (step).
S60). When the user performs a process for purchasing the product by a predetermined operation (step S61), the MPU 11 creates a predetermined process, that is, an ordering information case of the purchased product by a predetermined procedure. Stored in the non-volatile memory 14.

In step S60, if the user does not place an order for another product, it is determined whether or not the operation of the system is finished at that point (step S62). When the user performs a termination operation at that time by a predetermined operation, the MPU 11 stops the operation of the system by a predetermined process. If the user does not perform the end operation,
Since the MPU 11 returns the process to step S54, the user determines the product to be displayed next.

FIG. 16 is a schematic diagram for explaining the expansion function of the optimization display function of the electronic catalog system of the present invention. With the optimized display function of the electronic catalog system of the present invention, it is possible to change the screen size setting even during catalog reproduction. By using this function, it is possible to display an enlarged image.

For example, the screen 30 of the monitor 2 in FIG.
It is assumed that the size of 0 is 29 inches, and the image of the product is displayed in a relatively small size in its original size as indicated by reference numeral 510. In this state, if the button 501 for setting the screen size is clicked, a submenu screen as indicated by reference numeral 500 is displayed. If the current monitor size of 29 inches is changed to 14 inches on the submenu screen 500, the MPU 11 is interrupted and the value of the parameter "MEM1" is changed from "29" to "14". As a result, the image data in the video memory 20 is enlarged by the enlargement / reduction circuit 24 at the enlargement ratio which should be displayed on the 14-inch monitor in its original size, and then displayed on the 29-inch monitor screen 300. Therefore, as indicated by reference numeral 300E, it is possible to display an image which is 14 inches larger than the original size on the monitor screen.

By the way, the electronic catalog system of the present invention is provided with the nonvolatile memory 14 as described above.
This non-volatile memory 14 is mainly used for storing ordering information. For example, when the monitor size is selected on the screen 100 of the "screen size setting menu" shown in FIG. Non-volatile memory
If it is stored in 14, it is not necessary to set the monitor size each time the system is started.

In FIG. 17, the monitor size is 25 as described above.
FIG. 7 is a schematic diagram showing a screen 100 of a “screen size setting menu” at the time when the system is started when data indicating inches is stored in the nonvolatile memory 14. In this case, since the data indicating the monitor size has already been stored in the non-volatile memory 14, 25 is displayed on the screen 100.
A state in which the inch is set is displayed and the cursor is positioned on the setting end button 107. Therefore, unless the user replaces the monitor 2 with a different size, the monitor size can be selected by directly clicking.

In the above embodiment, the image of the product is displayed so that the absolute size on the screen of the monitor 2 is the original size. However, even if the image is not displayed exactly in the actual size, it corresponds to the monitor size. The display may be appropriately enlarged or reduced.
