Description

  The present invention relates to an information processing apparatus and an information processing method for displaying a file on a display device.

  In recent years, multifunctional and high-functional image processing apparatuses capable of directly printing image data alone without using a PC are becoming widespread. Such an image processing apparatus is often provided with a user interface capable of graphical representation so that a user can use many functions as easily as possible.

  However, the user interface becomes complicated because many functions can be operated, and the operability for the user may also become complicated. For example, recent image processing apparatuses have interfaces for various devices, and can handle image data of different devices such as a memory card, flash memory, and hard disk. In the case where a plurality of devices are connected to such an image processing apparatus at the same time, conventionally, the operation by the user is effective only for one device, and the other devices are excluded as operation targets. Therefore, it is necessary for the user to repeatedly perform an operation of setting a target device among a plurality of devices connected to the image processing apparatus. Specifically, the operation by the user is complicated because the screen transition occurs multiple times on the menu screen.

  In order to cope with such a situation, it is considered to select a medium and determine an output device on one screen without switching the display screen (for example, see Patent Document 1). Thereby, a user's load is reduced and operation performance is improved.

  FIG. 8 is a flowchart showing a processing procedure when image data is input to the image processing apparatus 100 from a device other than the memory card according to the first embodiment of the present invention.

  First, in step S <b> 801, the interface control unit 203 detects which device has input image data to the image processing apparatus 100. Here, the device is a mobile phone. In step S802, the system control unit 200 determines whether device information indicating that image data can be input from the mobile phone is displayed on the liquid crystal display device 106. If device information is being displayed, the process proceeds to step S803. If not, the process is terminated. In step S <b> 803, the system control unit 200 determines whether the device detected in step S <b> 801 matches the device targeted by the device information displayed on the liquid crystal display device 106. If both devices match, the process proceeds to step S804. If they do not match, the process ends.

  Further, when the process is ended, if there is device information of another target device in the list, the device information may be switched.

  In step S <b> 804, the interface control unit 203 acquires image data from the mobile phone that has input the file to the image processing apparatus 100 and stores the image data in the reception buffer 210.

  In step S805, the interface control unit 203 analyzes the image data received in step S804, and determines whether the format of the image data is compatible with the image processing apparatus 100, for example, JPEG format. . If it is compatible with the JPEG format, the process proceeds to step S806. If not, the process ends. In addition, a warning screen indicating that the file format is different may be displayed before the processing ends. In step S806, the interface control unit 203 temporarily stores the image data stored in the reception buffer 210 in step S804 in the internal RAM area 211.

  In step S807, the second file list creation unit changes the list created by the first file list creation unit so that it can be handled in the same manner as the image data that is the target of the list created by the first file list creation unit. Image data newly input from the mobile phone is added. In step S808, the display control unit 202 displays the image data and the input target device on the liquid crystal display device 106 in accordance with the list updated in step S807. The display control unit 202 performs control so that the display of the list is automatically switched according to an instruction to switch the display sequentially from the operation unit by the user or by a slide show.

  As described above, the image data acquired from the input device according to the created list and the image data indicating the input device can be displayed as a menu. Thereby, the user can save time for switching the menu screen in order to select the image data and the input device.

  In the first embodiment, image data is targeted, but a text file may be targeted. In the first embodiment, the input target device is added to the list even if it is not connected to the image processing apparatus 100. However, devices actually connected to the image processing apparatus 100 may be detected, and only the detected devices may be added to the list. Further, an item may be added that accepts an input from any device as long as the device is compatible with the image processing apparatus 100.

  In the first embodiment, the device for which a list of image data is first created is determined by the user selecting in the image data browsing mode. However, a device with the highest priority may be first created as an object for creating an image data list based on a predetermined priority order from among connected devices.

<Second Embodiment>
In the first embodiment, the input file is temporarily stored in the internal RAM area. For this reason, the contents temporarily stored at the time of turning off the power are erased and cannot be stored for a long time. Therefore, the second embodiment corresponds to this point, and realizes long-term storage of image data by storing input image data in a nonvolatile data storage area.

  In some cases, it may be desirable to view and select frame data for decorating image data acquired from an input device. Therefore, a list can be created by selecting frame data to be combined with image data as selection targets.

  An overview perspective view of an image processing apparatus 100 according to the second embodiment of the present invention is the same as FIG. 1, but a block configuration diagram of the image processing apparatus 100 is slightly different from FIG. Therefore, this point will be described.

  FIG. 10 is a block diagram of the image processing apparatus 100 according to the second embodiment of the present invention.

  The system control unit 200 is a control unit that controls the entire apparatus, and includes the following components. The first file list creation unit 201 creates a list of frame data acquired from a predetermined device connected to the image processing apparatus 100 and stores it in the built-in RAM area 211. For example, a list of frame data stored in the memory card in which the memory card is inserted in the card slot 108 is created and stored in the built-in RAM area 211.

  Furthermore, a device other than the memory card is added to the created list as an item of device information in the browsing mode.

  A display control unit 202 displays frame data on the liquid crystal display device 106 according to the created list. An interface control unit 203 saves the input image data in the nonvolatile memory 1000 as frame data if image data is input from the device displayed as device information to the image processing apparatus 100. Also, additional information indicating frame data is added.

  The second file list creation unit 204 adds the frame data stored in the nonvolatile memory 1000 to the list created in the internal RAM area 211. For example, frame data is added to the list from the mobile phone with respect to the list stored in the built-in RAM area 211 regarding the frame data input from the memory card.

  FIG. 11 is a flowchart showing a processing procedure when a frame data file according to the second embodiment of the present invention is displayed on the liquid crystal display device 106. First, in step S1101, it waits for the user to set the browsing mode using the operation panel 109. In step S 1102, a list of frame data stored in advance in the nonvolatile memory 1000 is temporarily stored in the built-in RAM area 211. In step S1103, the system control unit 200 searches for a device connected to the image processing apparatus 100 or a connectable device. In step S1104, the first file list creation unit adds the device searched in step S1103 to the list. In step S1105, the display control unit 202 displays frame data on the liquid crystal display device 106 in accordance with the list created in step S1102.

  FIG. 12 is a flowchart showing a processing procedure when frame data is input to the image processing apparatus 100 from a certain device according to the second embodiment of the present invention. Here, it is assumed that frame data is input from a device other than the memory card.

  First, in step S <b> 1201, the interface control unit 203 acquires what device has input a file to the image processing apparatus 100. In step S <b> 1202, the system control unit 200 determines whether device information is displayed on the liquid crystal display device 106. If device information is displayed, the process advances to step S1203. If not, the process is terminated. In step S1203, the system control unit 200 determines whether the device acquired in step S1201 is the same as the device targeted by the device information displayed on the liquid crystal display device 106. If the devices are the same, the process proceeds to step S1204. If not, the process is terminated. Further, when the process is ended, if there is device information of another device, the device information may be switched.

  In step S1204, the interface control unit 203 acquires the frame data from the device that has input the frame data to the image processing apparatus 100, and stores the frame data in the reception buffer 210. In step S1205, the interface control unit 203 determines whether it corresponds to the frame data format received in step S1204. For example, it is determined whether the frame data format is the image data format. There is a PNG format as a format of image data.

  If the file format is the image data format, the process advances to step S1206. If the determination result is not image data, the process ends. In addition, a warning screen indicating that the data format is different may be displayed before the processing ends. In step S1206, the interface control unit 203 stores the image data stored in the reception buffer 210 in step S1204 in the nonvolatile memory 1000. Further, additional information indicating the stored frame data is also stored in association with each other.

  In step S1207, the frame data stored in the nonvolatile memory 1000 is added to the list stored in the internal RAM area 211 in advance. As a result, it can be handled in the same way as existing frame data and can be selected by the user. In step S1208, the display control unit 202 displays frame data on the liquid crystal display device 106 in accordance with the list updated in step S1207.

  In the second embodiment, since the scene in which the frame data is the browsing mode is assumed, additional information indicating that the frame data is frame data is added. However, it goes without saying that even if it is handled as image data in JPEG format other than frame data according to the situation of the user interface, it is included in the invention according to the present application.

  Further, one list may be created by mixing frame data and image data. Also at this time, the additional information is effective for identifying the frame data and the image data.

  In the second embodiment, the frame data is stored in the nonvolatile memory 1000, but it goes without saying that the frame data is included in the invention according to the present application even if it is stored in a hard disk or a storage device.
