Description

  The present invention relates to an information processing apparatus, a control method for the information processing apparatus, and a program.

Conventionally, an input control method using a touch panel is configured to recognize that a touch has been made at the moment when a finger is released from the touch panel (hereinafter, touch-out). On the other hand, in the cancellation of the power saving state, there is one having a power saving cancellation method of recognizing that the touch is made and releasing the power saving state at the moment when a finger touches the touch panel (hereinafter, touch-in).
Hard key operation can be felt by the user touching the key with touch, whereas touch panel operation is not intended for the touch panel because there is a high possibility of erroneous operation due to contact with the touch panel that is not intended by the user. A method for preventing an erroneous operation caused by contact is known (Patent Document 1). In the power saving state, the screen of the touch panel is usually dark and nothing is displayed. For this reason, since there is a high possibility that an erroneous operation occurs immediately after the power saving state is released, a method for preventing an erroneous operation occurring immediately after the power saving state is released is known (Patent Document 2).

  However, the conventional technology does not show a countermeasure against erroneous operations caused by repeated hitting or chattering on the touch panel. Further, in the power saving cancellation method by touch-in on the touch panel, the user touches an arbitrary position (arbitrary coordinate value) of the touch panel in order to cancel the power saving state. Here, the power saving state is released. Then, at the moment when the finger touching an arbitrary position on the touch panel is released, the information processing apparatus recognizes that the touch has been performed. For this reason, depending on the touch position of the screen displayed immediately after canceling power saving, there has been a problem that processing is executed assuming that an unintended operation is instructed.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a mechanism that can prevent an erroneous operation even if a user touches an unintended screen position immediately after canceling the power saving state. It is to be.

The information processing apparatus of the present invention that achieves the above object has the following configuration.
A touch panel including a display unit and a touch unit; a screen control unit that receives a touch operation on the touch unit and cancels a sleep state of the display unit; and a first screen on the display unit that receives the touch operation. Display means for determining whether or not a position touched by the touch unit overlaps a specific position set on the first screen, and the screen control means includes the touched position. Is determined to overlap with the specific position set on the first screen, the screen display is controlled so as not to accept a touch operation on the first screen displayed on the display unit.

  According to the present invention, erroneous operation can be prevented even if the user touches a screen position that is not intended immediately after the power saving state is canceled.

<Description of system configuration>
[First Embodiment]

FIG. 1 is a block diagram illustrating the configuration of the information processing apparatus according to the present embodiment. In this example, the printing apparatus 100 that is an information processing apparatus is taken as an example.
In FIG. 1, a control unit 101 including a CPU 102 controls the operation of the entire printing apparatus 100. The CPU 102 reads out a control program stored in the ROM 104 and performs various controls such as communication control. The RAM 103 is used as a temporary storage area such as a main memory and work area of the CPU 102. The HDD 114 stores data, various programs, various information tables, and an erroneous operation invalid flag 1141 described later.

  The printer I / F 106 serves as an interface for outputting an image signal to the printer 107 (printer engine). The scanner I / F 108 serves as an interface for inputting a read image signal from the scanner 109 (scanner engine). The CPU 102 processes the image signal input from the scanner I / F 108 and outputs it to the printer I / F 106 as a recorded image signal. The operation panel I / F 110 connects the display unit 112 and the control unit 101, and the touch panel 111 and the control unit 101. The network I / F 113 transmits information to external terminals or receives various types of information from these external devices. Each block in the control unit 101 is connected by a system bus 105.

FIG. 2 is a diagram showing internal data of the HDD 114 of the printing apparatus 100 shown in FIG.
In FIG. 2, an invalid operation invalid flag 1141 is a flag for branching the processing when an erroneous operation occurs, and “1” is written by control described later when invalid operation is invalid and “0” when invalid operation is not invalidated. .

  FIG. 3 is a diagram for explaining a software configuration of the printing apparatus 100 shown in FIG. Each functional unit illustrated in FIG. 3 is realized by the CPU 102 included in the printing apparatus 100 executing a control program.

  In FIG. 3, the input control unit 200 controls the touch panel 111. It waits for an instruction input from the user or notifies the screen control unit 202 that displays the received instruction content on the screen. In the present embodiment, touching a finger on the touch unit 115 by the user is referred to as touch-in, and releasing the finger from the touch unit 115 is referred to as touch-out. In the present embodiment, a series of operations from touch-in to touch-out is called a touch operation. The input control unit 200 notifies the screen control unit 202 of soft key information on which a touch operation has been performed. The display control unit 201 displays an operation menu on the display unit 112 and displays an instruction result on the display unit 112.

  Based on the soft key information from the input control unit 200, the screen control unit 202 transmits processing corresponding to the soft key to other function units. When the soft key processing is screen transition, the next screen drawing instruction is issued to the display control unit 201. In the case of execution processing, an execution request is issued to the application unit 205.

  The storage unit 203 stores designated data in the ROM 104 or the HDD 114 or reads stored data in accordance with instructions from other functional units. Further, the storage unit 203 reads the erroneous operation invalid flag 1141 from the HDD 114 when an erroneous operation occurs, and transmits it to the screen control unit 202. The screen control unit 202 performs key touch processing using the erroneous operation invalid flag 1141 under the control described later.

  The timer processing unit 204 performs time measurement processing according to instructions from other functional units. Then, the timer processing unit 204 stores a predetermined time measured from the timer start request, and notifies the other functional units when the predetermined time has elapsed.

  The application unit 205 provides a service in response to a request from the screen control unit 202. A printer service and a scan service are provided using a printer I / F 107, a scanner I / F 108, and the like.

4 and 5 are diagrams illustrating an example of a UI screen displayed on the display unit 112 illustrated in FIG. This example is an example of the home screen A associated with the copy function.
As shown in FIG. 4, the home screen configuration includes copy setting information, a START button B2 that starts copying when pressed, and a STOP button B1 that stops copying when pressed. .
FIG. 5 is an example of a confirmation screen B displayed on the display unit 112 shown in FIG. The screen configuration is composed of “Yes” and “No” soft keys S1 and S2. If the user touches the “Yes” soft key S1, the process is started. If there is a touch operation on the “No” soft key S2, the processing is invalidated and the previous screen is displayed.

  FIG. 6 is a flowchart illustrating a method for controlling the information processing apparatus according to the present exemplary embodiment. This example is an erroneous operation prevention processing example of the screen control unit 202 accompanying the user's touch operation immediately after canceling power saving in the printing apparatus 100. Each step is realized by the CPU 102 executing a control program (including software shown in FIG. 3) stored therein. At the start of this process, nothing is displayed on the display unit 112, and the screen is a black screen. This processing is assumed to start in a power saving state corresponding to the sleep state of the main body.

In step S <b> 301, the screen control unit 202 receives a user touch-in from the input control unit 200. In step S <b> 302, the screen control unit 202 cancels the hardware power saving state through the power control unit 206.
Next, the screen control unit 202 requests the display control unit 201 to draw a copy screen that is the first screen set as the home screen A.
Some image processing apparatuses have a function that allows the user to set the home screen A to an arbitrary one, and a copy screen or a scan screen can be displayed as the home screen A. In the present embodiment, it is assumed that the copy screen is set as the home screen A, and the home screen A is displayed.
In S303, the screen control unit 202 determines that the coordinate value of the touch-in by the user received from the touch panel 111 is a coordinate value of a specific position, for example, the coordinate of the START button B2 on the home screen A, with respect to the home screen A displayed in S302. Determine if it overlaps with the value. As a result, if the screen control unit 202 determines that they overlap, the process of S304 is performed.

In step S304, the screen control unit 202 stores the erroneous operation invalid flag 1141 in the HDD 114 as “1” to prevent erroneous operation. In step S <b> 305, the screen control unit 202 issues a time measurement request for N seconds to the timer processing unit 204. In step S <b> 306, the screen control unit 202 receives soft key information touched out by the user from the input control unit 200. In step S307, the screen control unit 202 determines whether the received soft key information is a touch-out for the START button B2 for executing copying. As a result, if the screen control unit 202 determines that the touch-out is to the START button B2, the process of S308 is performed.
On the other hand, if the screen control unit 202 determines that the touch-out is not for the START button B2, the process proceeds to S312. In step S312, the screen control unit 202 receives an input. Specifically, a touch-out for the START button B2 is accepted, a copy execution request is issued to the application unit 205, and the process proceeds to S313.

  On the other hand, if it is determined in S308 that the screen control unit 202 has not received an expiration notification indicating that N seconds have elapsed from the timer processing unit 204, the process proceeds to S312. On the other hand, if the screen control unit 202 determines that an expiration notification has been received, the process proceeds to S309.

In step S309, the screen control unit 202 receives the erroneous operation invalid flag 1141 from the storage unit 203, and determines whether the received erroneous operation invalid flag 1141 is “1”. If the screen control unit 202 determines that the received erroneous operation invalid flag 1141 is “1”, the process proceeds to S310, and the screen control unit 202 determines that the erroneous operation invalid flag 1141 is “0”. Advances to S311.
In S310, the screen control unit 202 grays out the START button B2 displayed on the first screen so that the touchout to the START button B2 is disabled, that is, the touch input from the user received in S306 is disabled, The user is once confirmed to confirm that the user instruction is a button position that causes an erroneous operation. Thereafter, the erroneous operation invalid flag is set to “0” (S315), and the START button B2 is normally displayed on the first display screen in S316. Here, after the user once again enters a state of accepting the touch operation of the START button B2, the process returns to S306. Thereby, in S309, since the operation invalid flag is “0”, the process proceeds to S311.
On the other hand, in S311, since the operation invalid flag is determined to be “0” in S309, that is, the coordinate value touched by the user does not overlap the coordinate position of the START button B2, the screen control unit 202 performs display control. The drawing request for the confirmation screen B is displayed on the display unit 112 to the unit 201, and the process returns to S301. As a result, it is possible to request the user's confirmation through the confirmation screen B whether the copy screen is registered as the start screen.
Then, the screen control unit 202 waits for a button instruction from the user on the confirmation screen B, that is, touch input of the button S1 or the button S2, and confirms the operation request from the user. Thereby, it is possible to avoid an erroneous operation that continues the copy screen process even when the copy request is not made by the user touching the screen. When the screen control unit 202 confirms that the button S1 is touched on the display of the confirmation screen B, the process proceeds to a process for executing the copy function process (S313). Details of the copy function process are omitted.
On the other hand, when the screen control unit 202 determines that the coordinate value of the touch-in by the user received in S303 does not overlap with the coordinate value of the START button B2 on the home screen A, the process proceeds to S313 and the erroneous operation invalid flag 1141 is set. Set to “0” and go to S312. In this case, a touch-out for the START button B2 is received from the user, a copy execution request is issued to the application unit 205, and the process proceeds to S313.

Note that S306 is acquired as a result of waiting for reception from the input control unit 200. If there is no user touch-out, nothing is received, and input must be waited.
In FIG. 6, the input waiting process is omitted for the sake of simplicity of the flowchart.
According to the present embodiment, it is possible to prevent erroneous operations due to repeated hitting and chattering on the touch panel. Further, in the power saving cancellation method by touch-in, it is possible to prevent an erroneous operation associated with the touch-in by the user after the power saving cancellation.
Note that the timer time in S305 may be configured so that a variable value can be set within a specified value range according to the user environment.
Furthermore, in the present embodiment, a case has been described in which the control is executed by comparing the coordinate value of one key with respect to the copy screen with the touched coordinate value, but a process for determining a plurality of keys on one screen In any case, the control for displaying the confirmation screen may be executed.

  The present invention supplies a program that realizes one or more functions of the above-described embodiments to a system or apparatus via a network or a storage medium, and one or more processors in a computer of the system or apparatus read and execute the program This process can be realized. It can also be realized by a circuit (for example, ASIC) that realizes one or more functions.
