Description

  An embodiment of the present invention relates to a display control device and a control program.

  One of the devices constituting the POS system is a product reading device. The product reading device optically reads a code symbol such as a bar code attached to the product. The merchandise reading device obtains the merchandise identification code from the read code symbol, searches the merchandise database, and reads out the data of the merchandise identified by the identification code, such as the name of the merchandise and the unit price. The product reading device registers the product sales data such as the identification code, the unit price, the number of points, and the amount of money in the memory, and displays the product name, the unit price, and the like on the display device.

Display devices include a customer display in addition to a display for an operator (usually a clerk) to browse. The customer display is provided in the merchandise reading device to display the unit price of the purchased merchandise read by the merchandise reading device or the total amount of all the purchased merchandise to the customer who performs the accounting for the purchased merchandise.
A display control device for displaying image content such as an advertisement together with data of a purchased product on the customer display is already known. In the conventional display control device, there is no relation between the amount of the product purchased by the customer and the display time of the image content. For this reason, for example, when a plurality of image contents are sequentially switched and displayed, there is a difference in the number of image contents that can be seen by a customer depending on the amount of purchased products.

JP-A-2005-069491

  A problem to be solved by an embodiment of the present invention is to provide a display control device that can efficiently show a plurality of image contents to a customer regardless of the amount of purchased products.

  In one embodiment, a display control device includes a display device capable of displaying a plurality of contents, a detection unit, a determination unit, and a control unit. The detecting means detects the weight of the merchandise which is not registered for sales among the merchandise purchased by the customer. The determining means determines the display pattern of the plurality of contents based on the weight of the product detected by the detecting means. The control means causes the display device to display a plurality of contents according to the display pattern determined by the determination means.

The merchandise reading device is installed at a checkout counter of a store, and scans and reads a merchandise code (usually a barcode system or a two-dimensional data code system) that is an identification code of a product purchased by a customer. The customer display displays the image content together with the data of the product specified by the product code read by the product reading device under the control of the display control device. The image content may be any information that should be notified to the customer who performs the accounting for the purchased product. For example, an advertisement image of a new product, a notice image of a special sale, a coupon image of a product, or the like can be considered.

[First Embodiment]
FIG. 1 is an external view of a store accounting system including a product reading device 100 according to the present embodiment. As shown in FIG. 1, the store accounting system includes a commodity reading device 100 and a POS terminal 200.
The commodity reading device 100 is mounted on the checkout counter 300. The POS terminal 200 is installed on a drawer 500 placed on a cashier table 400. The commodity reading device 100 and the POS terminal 200 are electrically connected by a communication cable (not shown). An automatic change machine may be installed in place of the drawer 500.

The commodity reading apparatus 100 includes a housing 101, a keyboard 102, a touch panel 103, a customer display 104, and a scanner 105.
The housing 101 has a flat box shape and stands upright on the checkout counter 300. The housing 101 supports a keyboard 102, a touch panel 103, and a customer display 104 at an upper end, and supports a scanner 105 inside. The housing 101 has a reading window 101a facing the scanner 105. The scanner 105 can scan an object located in front of the reading window 101a.

The POS terminal 200 includes a housing 201, a keyboard 202, an operator display 203, a customer display 204, and a printer 205.
The housing 201 supports the keyboard 202 in a state where its key arrangement portion is exposed to the outside, supports the operator display 203 and the customer display 204 in an externally located state, and supports the printer 205 inside.

  The accounting counter 300 includes an elongated top plate 300a. The checkout counter 300 divides a customer passage (rear side in FIG. 1) along the longitudinal direction of the top plate from an operator space (front side in FIG. 1). The housing 101 of the commodity reading device 100 is attached to the top plate 300a. The housing 101 is located substantially at the center of the top plate 300a in the longitudinal direction. The housing 101 supports the keyboard 102, the touch panel 103, and the reading window 101a toward the operator space, and supports the customer display 104 toward the customer passage.

  On the upper surface of the top plate 300a, an area on the upstream side in the customer moving direction across the commodity reading device 100 is for placing unregistered commodities among commodities purchased by the customer who have not yet registered sales. Used as space for The downstream area is used as a space for placing products for which sales have been registered, so-called registered products. A part of the space for placing unregistered products on the top plate 300a is a weighing unit 600. The weighing unit 600 includes a load cell 601 (see FIG. 2), and measures the weight of an object placed on the weighing unit 600. On the weighing unit 600, a shopping basket in which goods purchased by a customer who performs accounting are usually stored is placed. In some cases, the purchased product is directly placed on the weighing unit 600 without using a shopping cart. Incidentally, the upper surface of the weighing unit 600 is flush with the upper surface of the top plate 300A, and the shopping basket placed in a space other than the weighing unit 600 can be slid on the weighing unit 600 and moved.

  FIG. 2 is a block diagram showing a main circuit configuration of the commodity reading apparatus 100. The commodity reading apparatus 100 includes a CPU (Central Processing Unit) 111, a ROM (Read Only Memory) 112, a RAM (Random Access Memory) 113, an auxiliary storage device 114, a timer 115, a communication interface 116, a signal input / output circuit 117, and a system bus. 118. The commodity reading apparatus 100 configures a computer by connecting the CPU 111, the ROM 112, the RAM 113, and the auxiliary storage device 114 via the system bus 118. Further, the commodity reading apparatus 100 connects the timer 115, the communication interface 116, and the signal input / output circuit 117 to the system bus 118.

  The CPU 111 corresponds to a central part of the computer. The ROM 112 corresponds to a main storage of the computer. The ROM 112 stores the above-described operating system and application programs. The RAM 113 corresponds to a main storage of the computer. The RAM 113 stores data necessary for the CPU 111 to execute processing. The auxiliary storage device 114 corresponds to an auxiliary storage part of the computer. The auxiliary storage device 114 is, for example, an EEPROM (Electric Erasable Programmable Read-Only Memory), a HDD (Hard Disc Drive), or an SSD (Solid State Drive).

  The timer 115 measures a set time. The communication interface 106 controls data communication performed with the POS terminal 200 connected via a communication cable. The signal input / output circuit 117 exchanges data signals with input / output devices supported by the housing 101, that is, the keyboard 102, the touch panel 103, the customer display 104, and the scanner 105. Further, the signal input / output circuit 117 captures an electric signal output from the load cell 601 of the weighing unit 600 provided in the checkout counter 300.

  The keyboard 102 includes a plurality of key switches, and outputs a command representing the content of an operation performed by the operator on these key switches.

  The touch panel 103 includes, for example, a display device such as an LCD (liquid crystal display), and a transparent two-dimensional touch sensor arranged so as to overlap the display screen of the display device. The touch panel 103 displays an arbitrary image on a display device under the control of the CPU 111. The touch panel 103 detects a touch position of the operator on the display screen of the display device by a two-dimensional touch sensor, and outputs coordinate data representing the touch position. The touch panel 103 is used for displaying images representing various types of information to be presented to the operator, and for inputting an operation of the operator.

  The customer display 104 displays an arbitrary character string or image under the control of the CPU 111. The customer display 104 is used to display various character strings and images to be presented to the customer. As the customer display 104, for example, a fluorescent tube display or an LCD can be used. It is also possible to use a touch panel as the customer display 104.

The scanner 105 optically reads a product code, which is an identification code of a product held in front of the reading window 101a. Each product is provided with a code symbol of a bar code system or a two-dimensional data code system including a product code. The scanner 105 optically reads information represented by a code symbol, that is, information including a product code. Then, the scanner 105 outputs the read information to the CPU 111. Such a scanner 105 can use a known device of a type that reads a code symbol using reflection of laser light. The scanner 105 may use a known device of a type that recognizes a code symbol from an image obtained by imaging a product.
The load cell 601 converts a load applied by a shopping basket or a purchased product placed on the weighing unit 600 into an electric signal and outputs the electric signal to the CPU 111.

  In the commodity reading device 100 having such a configuration, the CPU 111, the ROM 112, the RAM 113, the auxiliary storage device 114, the timer 115, and the signal input / output circuit 117 constitute a display control device for the customer display 104. Hereinafter, the display control device will be specifically described.

  FIG. 3 is an example of the registration screen 700. The registering screen 700 is displayed on the customer display 104 by the display control device from the start to the end of registration of the product purchased by the customer. When the first product code of a product sold as one transaction is input, the CPU 111 recognizes that registration has started. For example, when the code symbol of the first product purchased by one or a set of customers is read by the scanner 105, the CPU 111 recognizes that registration has started. When the registration is determined to be started, the CPU 111 causes the display for customer 104 to display the registering screen 700. When the end of the reading of the product sold as one transaction is declared, the CPU 111 recognizes that the registration is completed. For example, when the operator touches the end button displayed on the touch panel 103, the CPU 111 recognizes that the registration has been completed. If it is determined that the registration has been completed, the CPU 111 deletes the registration screen 700.

  The registration screen 700 is divided into a data display unit 701 and an image display unit 702. In this embodiment, the screen is divided into upper and lower parts, the upper screen is used as the data display unit 701, and the lower screen is used as the image display unit 702. The upper screen may be used as the image display unit 702, and the lower screen may be used as the data display unit 701. The screen may be divided into left and right, and one screen may be used as the data display unit 701 and the other screen may be used as the image display unit 702.

  The data display unit 701 includes a display area 701a of a product name, a display area 701b of a purchase point and a purchase price, and a display area 701c of a total point and a purchase price. In the display area 701a, the product name of the product identified by the product code read by the scanner 105 is displayed. The display area 701b displays the purchase points and the purchase price (unit price × purchase points) of the product. The display area 701c displays the total points and the total price of commodities registered as one transaction.

When code symbol information read by the scanner 105 is input, the CPU 111 obtains a product code from the information. When the product code is obtained, the CPU 111 searches the product database stored in the auxiliary storage device 114, and reads out data of the product identified by the product code, for example, the product name, the unit price, and the like. Then, the CPU 111 registers the merchandise sales data such as the merchandise code, the unit price, the score, and the amount of money in the RAM 113. The CPU 111 displays the product name in the display area 701a, and displays the score and the amount in the display area 701b. Further, the CPU 111 causes the display area 701c to display the total points and the total amount of the merchandise sales data registered in the RAM 113.
Such display control on the data display unit 701 is realized by the CPU 111 performing information processing according to a display control program stored in the ROM 112 or the auxiliary storage device 114.

  On the other hand, display control for the image display unit 702 is also realized by the CPU 111 performing information processing according to the display control program. In order to realize this display control, the display control device stores, in the RAM 113 or the auxiliary storage device 114, the content table 801 having the data structure shown in FIG. 4A and the data table having the data structure shown in FIG. A weight / time table 802 is formed.

  The content table 801 stores a plurality of pieces of content data X, A, B, C, D,... In association with serial numbers starting from “0”. The content data X, A, B, C, D,... Are all image data that can be displayed on the image display unit 702. The image data is, for example, an advertisement image of a new product, a notice image of a special sale, a coupon image of a product, and the like. The type of image data is not particularly limited. In the present embodiment, five pieces of content data X, A, B, C, and D are stored in the content table 801 in association with the serial numbers “0” to “4”.

  The weight / time table 802 stores the time T for the range of the weight M divided stepwise. Weight M is the total weight of the product purchased by one or a set of customers. The time T is a display time of one content data. The display control device causes the image display unit 702 to appropriately display the content data stored in the content table 801. In the present embodiment, the display time T of the content data is changed according to the total weight M of the product. Specifically, when the total weight M of the product is equal to or less than Ma [g: gram], the display time T is set to T1 [second]. If the total weight M of the product is heavier than Ma [g] and equal to or less than Mb [g] (M2> M1), the display time T is set to T2 [seconds] (T2> T1). When the total weight M of the product is heavier than Mb [g], the display time T is set to T3 [seconds] (T3> T2> T1). That is, the weight and time data are set in the weight / time table 802 such that the display time T becomes shorter as the total weight M of the product becomes lighter.

  FIG. 5 is a flowchart showing an information processing procedure of display control for the image display unit 702. The CPU 111 executes the information processing of the procedure shown in the flowchart of FIG. 5 according to the display control program stored in the ROM 112 or the auxiliary storage device 114. Note that the contents of the processing shown in FIG. 5 and described below are merely examples, and various processing capable of obtaining similar results can be appropriately used.

  The CPU 111 resets the number counter N to “0” as Act1. The number counter N is formed in the RAM 113, for example. After resetting the number counter N, the CPU 111 reads out the content data X associated with the value of the number counter N (N = 0) from the content table 801 as Act2. Then, the CPU 111 causes the image display unit 702 to display an image based on the content data X.

  The CPU 111 detects the weight data measured by the weighing unit 600 based on the electric signal output from the load cell 601 as Act3. Then, the CPU 111 stores the weight data in the first work memory M1 as Act4 (detection means). The first work memory M1 is formed in the RAM 113. The CPU 111 checks whether the weight data (hereinafter, referred to as weight M1) stored in the first work memory M1 as Act5 is larger than “0”. When an object is placed on the weighing unit 600, the weight M1 takes a value larger than “0”. However, when no object is placed on the weighing unit 600, the weight M1 is “0”. If the weight M1 is "0" (NO in Act5), the CPU 111 returns to the process of Act3. Therefore, an image based on the content data X is displayed on the image display unit 702 while a shopping cart or the like is not placed on the weighing unit 600.

  For example, when the shopping basket containing the customer's purchased goods is placed on the scale unit 600, the weight M1 takes a value larger than “0”. When the weight M1 takes a value larger than “0” (YES in Act 5), the CPU 111 determines the time T from Act M6 as Act6. That is, the CPU 111 searches the weight / time table 802 and reads out the time T in a range (level) including the weight M1. Then, the CPU 111 sets the time T in the timer 115 (determining means).

  In the present embodiment, the weight of the shopping basket is ignored. That is, when the shopping basket containing the purchased merchandise is placed on the weighing section 600, the total weight of the purchased merchandise including the shopping basket is defined as the total weight M1. Since the weight of the shopping basket is almost uniform and relatively light, there is no problem in ignoring the weight. Incidentally, when the total weight of the purchased merchandise is accurately obtained excluding the weight of the shopping basket, a shopping basket key is set on the keyboard 102, for example. When the shopping basket key is operated, a value obtained by subtracting a predetermined shopping basket weight from the weight measured by the weighing unit 600 is set as a total weight M1 of the purchased merchandise. Alternatively, a key without a shopping basket is set on the keyboard 102. When the shopping basket-less key is not operated, a value obtained by subtracting a predetermined shopping basket weight from the weight measured by the weighing unit 600 is defined as the total weight M1 of the purchased product. When operated, the weight measured by the weighing unit 600 is used as it is as the total weight M1 of the purchased merchandise.

  The CPU 111 increments the number counter N by "1" as Act7. Then, the CPU 111 checks whether or not the number counter N has exceeded the maximum serial number “4” of the content table 801 as Act 8. If the number counter N exceeds the maximum value “4” (YES in Act 8), the CPU 111 returns the number counter N to “1” as Act 9. Then, the CPU 111 proceeds to the process of Act10. On the other hand, if the number counter N does not exceed the maximum value “4” (NO in Act 8), the CPU 111 proceeds to Act 10 processing without performing Act 9 processing.

  In Act 10, the CPU 111 reads the content data associated with the value of the number counter N from the content table 801. Then, the CPU 111 causes the image display unit 702 to display an image based on the content data (control means). Therefore, when the value of the number counter N is “1”, the image of the content data A is displayed on the image display unit 702.

  At the same time that the image based on the content data is displayed on the image display unit 702, the CPU 111 activates the timer 115. Then, the CPU 111 checks whether or not the timer 115 has timed out as Act 11. When the counted time reaches the set time T, the timer 115 times out. If the timer 115 has not timed out (YES in Act 11), the CPU 111 takes in the weight data measured by the weighing unit 600 based on the signal of the load cell 601 as Act 12. Then, the CPU 111 stores the weight data in the second work memory M2 as Act13. The second work memory M2 is formed in the RAM 113. The CPU 111 checks whether the weight data (hereinafter, referred to as weight M2) stored in the second work memory M2 as Act 14 is larger than “0”. When the weight M2 is larger than “0”, an object such as a shopping basket remains on the weighing unit 600. In this case (NO in Act 14), the CPU 111 returns to the processing of Act 11. That is, the CPU 111 checks whether or not the timer 115 has timed out.

When the timer 115 times out (YES in Act 11), the CPU 111 returns to the process of Act 7. Thereafter, the CPU 111 executes the processes after Act 7 in the same manner as described above.
When the weight M2 becomes “0” (YES in Act 14), the CPU 111 returns to the processing of Act1. Thereafter, the CPU 111 executes the processing after Act 1 in the same manner as described above.

  By performing the display control on the image display unit 702 in such an information processing procedure, the image display unit 702 displays the content data A, B, C, and D set in the content table 801 in the following display pattern. The image is displayed. That is, the images of the content data A, B, C, and D are sequentially displayed in a pattern that switches every display time T determined from the total weight M1 of the purchased product measured by the weighing unit 600. Then, when the weight of the purchased product is no longer measured by the weighing unit 600, an image of the content data X is displayed on the image display unit 702. Note that the content data X may be omitted. In this case, when the weight of the purchased product is no longer measured by the weighing unit 600, no image is displayed on the image display unit 702.

  The display time T varies depending on the total weight M1 of the purchased merchandise. That is, the lighter the total weight M1, the shorter the display time T. When the number of purchased products is small, the total weight M of the products is generally reduced. When the number of purchased products is small, the time required for registration of the purchased products is short. Therefore, the time for the customer to browse the image on the customer display 104 is reduced. In the present embodiment, the display time T becomes shorter as the total weight M of the product is lighter, so that a large number of content data images can be shown to a customer with a small number of purchased products.

Conversely, when the number of purchased products is large, the total weight M of the products generally increases. In addition, when the number of purchased products is large, the time required to register the purchased products is long. Therefore, the time for the customer to browse the image on the customer display 104 becomes longer. In the present embodiment, the display time T becomes longer as the total weight M of the products is larger, so that the customer of a large number of purchased products can slowly see the image of the content data.
Thus, according to the present embodiment, a plurality of image contents can be efficiently shown to a customer regardless of the amount of purchased goods.

[Second embodiment]
In the second embodiment, as in the first embodiment, a display control device for the customer display 104 will be described. Note that FIGS. 1 to 3 used in the description of the first embodiment are common to the second embodiment, and a description thereof will be omitted.

  In the second embodiment, a time setting table 900 having a data structure shown in FIG. 6 is provided in the RAM 113 or the auxiliary storage device 114 instead of the weight / time table 802. The time setting table 900 stores a standard display time t1 of the image content and a correction time t2 (t2 <t1) of the standard display time. The standard display time t1 is an appropriate time (for example, 10 seconds) as a time for displaying the images of the content data A, B, C, and D set in the content table 801 on the image display unit 702. The correction time t2 is an arbitrary time (for example, 2 seconds) shorter than the standard display time t1.

  7 to 9 are flowcharts showing an information processing procedure of display control for the image display unit 702. The CPU 111 executes information processing of the procedure shown in the flowcharts of FIGS. 7 to 9 according to the display control program stored in the ROM 112 or the auxiliary storage device 114. The contents of the processes shown in FIGS. 7 to 9 and described below are merely examples, and various processes capable of obtaining the same result can be appropriately used.

  The CPU 111 executes the same processing as Act1 to Act5 of the first embodiment as Act21 to Act25. When the weight M1 measured by the weighing unit 600 becomes larger than “0” (YES in Act 25), the CPU 111 determines whether the weight M1 is equal to or more than the first threshold value Ws as Act 26. If the weight M1 is equal to or greater than the first threshold value Ws (YES in Act 26), the CPU 111 executes single mode processing as Act 27. On the other hand, when the weight M1 is smaller than the first threshold value Ws (NO in Act 26), the CPU 111 executes the split mode process as Act 28.

  In the single mode, an image of one content data is displayed on the screen of the image display unit 702. In the division mode, the screen of the image display unit 702 is divided into two parts, left and right or up and down, and images of two content data are displayed at the same time. For example, when it is desired to show each image of the content data A, B, C, and D to the customer for 10 seconds or more, 40 seconds are required in total. Therefore, the weight at which the registration processing time assumed from the weight M1 is 40 seconds is set as the first threshold value Ws. By setting the first threshold value Ws in this manner, when the registration processing time is shorter than 40 seconds, the split mode processing is executed, and when the registration processing time is 40 seconds or longer, the single mode processing is executed.

  When the single mode process is started, the CPU 111 sets the standard display time t1 in the timer 115 as Act 31 as shown in FIG. Next, the CPU 111 executes the same processing as Act6 to Act14 of the first embodiment as Act32 to Act39. If the weight M2 is larger than “0” (NO in Act 39), the CPU 111 calculates the difference weight ΔM between the weights M1 and M2 as Act 40. Then, the CPU 111 determines whether or not the difference weight ΔM is larger than the second threshold value Wx as Act 41.

  In the present embodiment, it is assumed that when the weight M1 is equal to or more than the first threshold value Ws, the registration processing time is long. However, if at least one heavy item such as “rice” or “beverage in a case” is included, the registration processing time is shorter than assumed. When a product with a heavy weight is registered, the weight measured by the weighing unit 600 changes greatly. Therefore, in the present embodiment, the second threshold value Wx is set to, for example, 1 kg, and when the difference weight ΔM exceeds 1 kg (YES in Act 41), the CPU 111 shortens the set time T 1 of the timer 115 as Act 42 by the correction time t 2. (Correction means). Then, the CPU 111 returns to the process of Act 36, and checks whether or not the timer 115 has timed out. If the timer 115 has not timed out (NO in Act 36), the CPU 111 repeats the processing in Act 37 and thereafter. If the timer 115 has timed out (YES in Act 36), the CPU 111 returns to the process in Act 32.

  On the other hand, if the difference weight ΔM does not exceed 1 kg (YES in Act 41), the CPU 111 returns to the process of Act 36 without executing the process of Act 42. Therefore, in this case, the processing after Act 37 is repeated until the set time T1 before correction has elapsed.

  On the other hand, when the division mode is selected, the CPU 111 sets the standard display time t1 to the timer 115 as Act 51 as shown in FIG. Next, the CPU 111 sets the number counter N to “1” as Act 52. Then, the CPU 111 reads, from the content table 801, first content data associated with the value of the number counter N and second content data associated with the value of the number counter N + 1. Then, the CPU 111 causes the image display unit 702 to display two images based on the first and second content data. For example, the CPU 111 divides the screen of the image display unit 702 into two right and left parts, and displays an image based on the first content data on one side and an image based on the second content data on the other side. Therefore, when the value of the number counter N is “1”, the image of the content data A and the image of the content data B are displayed on the image display unit 702.

  At the same time as displaying these two images on the image display unit 702, the CPU 111 starts the timer 115. Then, the CPU 111 checks whether or not the timer 115 has timed out as Act 54. When the measured time does not exceed the set time t1 (NO in Act54), the CPU 111 executes the same processing as Act12 to Act14 of the first embodiment as Act55 to Act57.

  On the other hand, if the counted time exceeds the set time t1, that is, if a time-out occurs (YES in Act 54), the CPU 111 counts up the number counter N by "2" as Act 58. Then, the CPU 111 checks whether or not the number counter N has exceeded the maximum serial number “4” of the content table 801 as Act 59. When the number counter N exceeds the maximum value “4” (YES in Act 59), the CPU 111 returns to the process of Act 52, and returns the number counter N to “1”. Then, the CPU 111 proceeds to the process of Act53. On the other hand, if the number counter N does not exceed the maximum value “4” (NO in Act 59), the CPU 111 proceeds to Act 53 without performing Act 52.

  As described above, in the second embodiment, when the total weight M of the product is heavier than the first threshold value Ws, the single mode process is executed, and when the product is light, the split mode process is executed. When the single mode processing is executed, the images of the content data A, B, C, and D are switched and displayed one image at a time t1 on the image display unit 702. On the other hand, when the division mode processing is executed, the images of the content data A, B, C, and D are grouped into two sets, and are switched at time t1 and displayed on the image display unit 702. Therefore, when the split mode process is executed, that is, when it is assumed that the time required for registering the purchased product is short, when the single mode process is performed, that is, when the time required for registering the purchased product is long, The images of the content data A, B, C, and D can be shown to the customer in half the time as compared with an assumed case.

[Modification]
In the above embodiment, the amount of the purchased product is detected from the total weight of the purchased product, but the means for detecting the amount is not limited to this. For example, the shopping basket placed on the checkout counter 300 may be photographed from above by a camera, and the number of products in the shopping basket may be estimated from the photographed image.

  Further, for example, a key is provided on the keyboard 102 to indicate whether the quantity of purchased products is large or small. Then, the cashier may look at the shopping basket placed on the checkout counter 300, determine whether the quantity of the purchased product is large or small, and operate the key. In this case, the means for receiving the key input is the detecting means.

  Further, in the above-described embodiment, the display control device for the customer display of the product reading device has been exemplified. However, the present invention can be similarly applied to the display control for other displays.

  The transfer of the display control device is generally performed in a state where the control program is stored in the ROM. However, the present invention is not limited to this, and a control program transferred separately from the computer device may be written in a writable storage device included in the computer device in accordance with an operation of a user or the like. The transfer of the control program can be performed by recording on a removable recording medium or by communication via a network. The recording medium may be in any form as long as it can store a program such as a CD-ROM or a memory card and can be read by an apparatus. Further, the function obtained by installing or downloading the program may be one that realizes the function in cooperation with an OS (Operating System) inside the apparatus.

In addition, although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and their equivalents.
