Problems solved by technology

[0003] However, in conventional electronic music equipment, like the equipment disclosed in the above-mentioned publication, it uses a display device such as a liquid crystal display (LCD) device or a CRT display device to display music information, because the display device itself must be illuminated to display music information. The music information is displayed on its screen, and power must be continuously supplied to the display device in order to keep the music information displayed on the screen, so the huge power consumption causes great inconvenience
In addition, the luminescence of the display device itself tends to tire the user's eyes, so displaying music information on a luminous display device is not suitable for the user for a long time compared to music information such as musical scores and / or lyrics printed on plain paper or the like. to watch

Embodiment Construction

[0016] figure 1 is a block diagram illustrating a general hardware arrangement of an electronic music device using a music information display device according to an embodiment of the present invention. Such an electronic musical device such as an electronic musical instrument or a personal computer is controlled by a microcomputer including a microprocessor unit (CPU) 1 , a read only memory (ROM) 2 and a random access memory (RAM) 3 . CPU 1 controls the behavior of the entire electronic music device. Through the data and address bus 1D, the read-only memory 2, RAM 3, detection circuit 4, drive circuit 5, electronic paper drive circuit 6, tone generator (T.G.) circuit 7, effect circuit 8, external storage device 10, MIDI interface (I / F) 11 and communication interface 12 are connected to CPU 1 . Also connected to the CPU 1 is a timer 1A for timing various cycles and intervals such as signal interruption of the timer interrupt process. For example, the timer 1A generates a cl...

Abstract

A music information display device includes electronic paper, and control means for controlling the electronic paper so as to switch display of music information corresponding to a reproduced musical piece in synchronization with reproduction of a musical piece. When music information is to be displayed on the electronic paper, an instruction is given in consideration of the response time necessary for display switching of the electronic paper so that the display switching operation is started earlier than the display switching timing by a predetermined time, so that when the display switching Switching to the display of the music information corresponding to the currently reproduced musical piece part is completed before timing. With this method, music information that is automatically updated in synchronization with reproduced music pieces can be displayed on electronic paper to provide an easy-to-view and pleasing display with minimal power consumption. Furthermore, music information can be appropriately displayed without delay after reproduction of a musical piece.

Description

technical field [0001] The present invention generally relates to a music information display apparatus and method for displaying predetermined music information on a display device, and a program therefor. More particularly, the present invention relates to an improved music information display device and method for displaying music information on a thin, light and power-saving board-shaped electronic paper, and an improved program therefor. Background technique [0002] Hitherto, there have been known electronic music devices such as electronic musical instruments configured to display information such as musical scores and / or lyrics on predetermined display means in accordance with acquired performance information, score display information, or lyrics display information. such as music information. An example of such an electronic music device is disclosed in Japanese Laid-Open Patent Application Laid-Open No. 2002-258838. In a conventional electronic music device, like...
