  By the way, it may be desirable that the logo mark of the delivery destination property is displayed on the opening screen rather than the manufacturer's logo on the opening screen depending on the use place of the audio device and the circumstances of the provider and the user. However, the opening screen in the above-described conventional audio device cannot be changed freely by the user.

  An object of the present invention is to allow a user to freely change an opening screen of an audio device and to easily set and reset the opening screen.

  In order to achieve the above object, the present invention provides an audio device including a display unit, the unit receiving a first predetermined name file or a second predetermined name image file prepared by a user, When the first predetermined name file is received, the opening screen is set to the unregistered state. When the second predetermined name image file is received, the user-specified opening screen is set to the registered state. If the opening screen unregistered state is set when the power is turned on and the means for storing, the default opening screen is displayed, and if the user-specified opening screen registration state is set And means for displaying an opening screen including image data of the image file having the second predetermined name.

  Instead of the opening screen when the power is turned on, a scene corresponding screen may be displayed at the time of scene switching in the mixer device, and the scene corresponding screen may be designated by the user. Similarly, a configuration corresponding screen may be displayed when switching the configuration in the mixer apparatus, and the configuration corresponding screen may be designated by the user.

  The user-specified screen may be a combination of the user-specified image and predetermined fixed image data (for example, an image showing copyright). Whether it is an unregistered state or a user-specified screen registration state may be stored by storing a flag (a magic number described later) in a nonvolatile storage means. Further, instead of the flag, the setting state may be stored by preparing the image data itself to be displayed.

  According to the present invention, it is possible to display an image designated by the user at the time of activation of the audio equipment, which is advantageous in that the user's flexibility is increased. Further, if user-specified images are displayed at the time of switching scenes or configurations in the mixer apparatus, it is convenient to display user-preferred information at the time of switching. Furthermore, if a user-specified image and a fixed image such as a copyright display are combined and displayed, it is possible to display a copyright or the like that the manufacturer wants to display. Further, when it is desired to reset the screen, it is only necessary to transmit a file having a predetermined file name, so that the processing on the PC side is simple.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a hardware configuration example of an acoustic device 100 (here, a mixer engine) according to an embodiment of the present invention. A CPU (central processing unit) 101 is a processing device that controls the operation of the entire mixer engine. A RAM (random access memory) 102 is a volatile memory used for a load area and a work area of a program executed by the CPU 101. A ROM (read only memory) 103 is a nonvolatile memory that stores a control program executed by the CPU 101 and various data. The ROM 103 is a flash memory in which data can be freely read and written. A file system is mounted in a predetermined area in the area, and various data can be stored therein as files. The operation element 106 is an operation element such as a switch provided on the external panel of the mixer engine. The operation of the operation element 106 is detected by the detection circuit 105, and the detection result is sent to the CPU 101. The display unit 108 is a display (LCD) that displays various types of information. The display circuit 107 displays the given data on the display unit 108 based on an instruction from the CPU 101. A communication interface (I / F) 109 is an interface for connecting to an external device 121 such as a PC or an external network. Any connection method may be used. The DSP 104 executes various microprograms based on instructions from the CPU 101 and realizes a function as a mixer such as mixing of acoustic signals. The audio I / F 110 is an interface that inputs an acoustic signal processed by the DSP 104 or outputs an acoustic signal processed by the DSP 104. The external device 122 connected to the audio I / F 110 is various acoustic devices that input and output acoustic signals.

  FIG. 2 is a connection configuration diagram including the mixer having the configuration of FIG. The mixer 203 is a mixer according to this embodiment having the hardware configuration shown in FIG. The LCD 204 corresponds to the display unit 108 in FIG. The mixer 203 is connected to the PC 201 via a network using the hub 202 or the like. The PC 201 corresponds to the external device 121 in FIG. The PC 201 has a predetermined mixer control program installed and activated. Thereby, various commands can be transmitted from the PC 201 to the mixer 203 to control the mixer 203. User data on an opening screen in the mixer 203 described later is also transmitted from the PC 201 to the mixer 203. Here, the PC 201 and the mixer 203 are connected via the hub 202 (network), but the connection interface is not limited to this, and may be, for example, a USB or a serial interface.

  FIG. 3 shows a configuration of an opening screen displayed on the LCD 204 of the mixer 203 of the present embodiment. A region 301 at the top of the screen is a user changeable area where the user can set an arbitrary image. The lower area 302 is a fixed area at all times, and here, copyright is displayed.

  In the mixer 203 of the present embodiment, the opening screen can be arbitrarily changed. In the default state, when the mixer 203 is turned on, the manufacturer logo screen shown in FIG. 7A is displayed first, and then the product name and copyright screen shown in FIG. 7B are displayed. When the user transfers an image file having a predetermined file name USER_OPENING.BMP from the PC 201 to the mixer 203, the screen in FIG. 7B is replaced with the screen in FIG. That is, when the mixer 203 is turned on, the manufacturer logo screen shown in FIG. 7A is displayed first, and then the user-specific opening screen shown in FIG. 3 (the image of USER_OPENING.BMP is set in the area 301). Is displayed. When it is desired to return the opening screen to the default state again, a file having a predetermined file name BLANK.BMP is transferred from the PC 201 to the mixer 203.

  FIG. 4 shows a memory image of a predetermined address in the ROM 103 (flash memory) of the mixer 203 of this embodiment. The area shown here is an area where a file system is not mounted, and there is an area where a predetermined file system is mounted in the ROM 103 in addition to this. In the predetermined address area, a magic number 401, a copyright 402, and image data 403 are stored. The magic number 401 is a 16-byte character string, and the initial value is filled with FF of hexadecimal data (indicating that the image of the user's opening screen is not registered). When the user registers an image of the original opening screen, the magic number 401 stores “USER_OPENING.BMP” which is the file name of the image data. The copyright 402 is a predetermined product name and image data of the copyright screen (FIG. 7B) displayed in the constantly fixed area 302 of FIG. The image data 403 is image data displayed in the user changeable area 301 of FIG. When the opening screen is displayed, the image data of the copyright 402 and the image data 403 is expanded and displayed in the VRAM of the LCD 204. Note that the image data 403 is displayed on the upper side and the copyright 402 is displayed on the lower side on the LCD, but on the memory, the positional relationship of the data is reversed due to restrictions on hardware and display method.

  FIG. 5 shows the procedure of the opening screen display process executed when the mixer 203 of the present embodiment is powered on. In step 501, the manufacturer logo shown in FIG. 7A is displayed for a predetermined time, and in step 502, it is determined by referring to the magic number 401 in FIG. 4 whether there is user-specified opening screen data.

  If the magic number 401 is described as USER_OPENING.BMP, it means that there is user-specified opening screen data. Therefore, the user image is read in step 503, the copyright 402 is read in step 504, and the read user image is read. 3 and the copyright are combined to form the screen of FIG. Note that the user-specified opening screen data is stored under the file name USER_OPENING.BMP in an area where the file system of the ROM 103 is mounted. Therefore, in step 503, the file is read and processed into image data 403 in FIG. Since the copyright 402 and the image data 403 are completed by the processing up to step 505, the image is displayed as an opening screen for a predetermined time in step 507.

  If the magic number 401 is filled with hexadecimal FF in step 502, this means that there is no user-specified opening screen data, so the default product logo image (FIG. 7B) is read and step Display at 507 and finish. The prescribed product logo image file is stored in a region where the file system of the ROM 103 is mounted with a predetermined file name. Accordingly, in step 506, the default file is read and developed into the image data 403 in FIG.

  FIG. 6 shows a processing procedure for registering and deleting user-designated opening screen data. Registration of an image is instructed by transmitting an image file having a predetermined file name USER_OPENING.BMP from the PC 201 in FIG. 2 to the mixer 203. The deletion of an image is instructed by transmitting a predetermined file name BLANK.BMP (the contents of the file may not be present) from the PC 201 to the mixer 203.

  The mixer 203 first determines in step 601 whether the file name is one of the above. If so, it is determined in step 602 whether the file name is USER_OPENING.BMP for registration or BLANK.BMP for deletion. If the file name is for registration, the file name USER_OPENING.BMP is written in the magic number area 401 in step 603, the image file received in step 604 is stored in the area where the file system of the ROM 103 is mounted, and the process ends. To do. If the file name is for deletion in step 602, the magic number 401 is filled with hexadecimal FF in step 605, and the process ends.

  If registration or deletion of an image is executed in the process of FIG. 6, then, when the power of the mixer 203 is turned on, the process of FIG. 5 described above is executed, and an opening designated by the user according to the setting of the magic number 401 is performed. The screen or default opening screen will be displayed.

  In the present embodiment, when the image shown in FIG. 6 is registered or deleted, the magic number 401 is set and the image file is stored, and the display data shown in FIG. Although development to the light 402 and the image data 403 is performed, development to the copyright 402 and the image data 403 may be performed at the time of image registration or deletion processing in FIG. In that case, since the copyright 402 and the image data 403 are already set in the ROM 103 which is a nonvolatile memory, the copyright 402 and the image data 403 may be mechanically displayed as an opening screen when the power is turned on. Further, when such a method is used, the magic number 401 as a flag is not necessary, and since it is expanded into the copyright 402 and the image data 403 at the time of registration or deletion processing, the transferred image file May be deleted after the expansion.

  Although the opening screen has been described as an example in the above embodiment, when a scene is recalled in the mixer, a screen corresponding to the scene may be displayed for a predetermined time. A scene refers to a combination of parameters that define the mixer setting state. The mixer can arbitrarily set the signal connection relationship and the setting state of various controls. Such a set state as a whole can be set and stored in advance as a scene for each scene, and the set state can be easily reproduced by recalling it (scene recall). In such a scene recall, a predetermined screen corresponding to the scene may be displayed for a predetermined time in the same manner as the opening screen described above, and the screen may be switched to a user-specified one. .

  Further, when the configuration data is called up in the mixer, a predetermined screen may be displayed for each configuration. The configuration data is data that defines the mixer configuration. The functions of the mixer are mainly realized by the DSP 104, but there are some that the user can arbitrarily define the mixer configuration. The definition is made by arranging and connecting various components (for example, audio processor such as mixer (narrow sense), compressor, effect, crossover, fader, switch, pan, meter, etc.) on the PC. . The mixer configuration thus created is stored as configuration data. Then, by calling the configuration data, a mixer having the mixer configuration of the configuration data is realized. When such configuration data is called up, a predetermined screen corresponding to the configuration data is displayed for a predetermined time in the same manner as the opening screen described above, and the screen can be switched to a user-specified one. May be.

  Furthermore, instead of displaying an image at the time of start-up, scene recall, and calling of configuration data, or in addition to such display, a so-called screen saver can be used. This displays an opening screen, a screen corresponding to the scene at that time, and a screen corresponding to the configuration at that time when no operation is performed for a predetermined time. You may enable it to switch the screen displayed by such a screensaver to a user-specified screen.
