Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to still image display and music performance devices.

BACKGROUND OF THE INVENTION Conventionally, there have been devices that combine still image playback and audio playback for the purpose of education, commentary, and hobby use.

Problems to be Solved by the Invention However, when these conventional devices are used for purposes that require high-quality video playback and additional music, such as viewing art paintings for entertainment purposes, it is difficult to display these images. The device is made with the idea in mind that current television receivers can be used as is, so as with regular television receivers, flickering due to interlace and coloring of fine parts due to the narrow frequency band of color components may occur. There were problems such as imperfections and color bleeding, and it was impossible to reproduce high-quality images such as fine art paintings.

Additionally, devices that simply play back high-definition still images already exist, but these have no accompanying sound and are unappealing for entertainment purposes. In addition, since it is desired to use more of the storage device for images, there have been expectations for a device that can provide high-definition still images and music at the same time, and that uses a small amount of storage data for music.

The apparatus of the present invention solves these conventional problems and simultaneously provides high-definition still images and music using a small amount of data.

Means for Solving the Problems In order to achieve the above objects, the still image display and music performance device of the present invention includes: (1) a data storage device, and RG and B 8 each.
Color image memory with gradation expression beyond focus, and M
The configuration includes an automatic music performance device based on the II standard and a control device that controls all the devices. Also, (2)
A data recording device, a color image memory with gradation expression of 8 bits or more for brightness, saturation, and saturation, a non-interlaced display device, an automatic music playing device based on the MIDI standard, and a controller that controls all devices. This is a configuration equipped with a device.

Function: With the above-described configuration, the present invention transfers high-definition image data recorded in a data recording device to a color image memory by a control device, and displays high-definition still images on a non-interlaced display device. In addition, by controlling a music performance device based on the MIDI standard using the control device, a device that can obtain high-quality still images and music can be realized.

EXAMPLES Below, regarding the embodiments of the present invention, please refer to the drawings. 1 is a data recording device for recording video and audio data, 2 is a color image memory, and the image data stored in the data recording bag W1 is transferred. and store it here temporarily. 3 is a non-interlace display device which reads data stored in the color image memory 2 as a non-interlace video signal and displays it on a cathode ray tube. 4 is an automatic music playing device based on the MIDI standard, which drives a synthesizer using data recorded in the data recording device 1 to automatically play music. Reference numeral 5 denotes a control device that comprehensively controls the entire device, including data transfer and designation of images and music.

FIG. 2 shows an example of a specific circuit of the main part.

A control circuit 6 transfers data and controls each device. A CD-ROM player 7 reads out video and music data recorded on the CD-ROM. 8 is a color image memory, and data corresponding to the screen is transferred here from a CD-ROM; 69 is a CRT controller that reads out the data in the color image memory 8 and outputs it as a video signal; 1;
0 is the display. 11 is a MIDI sequencer that outputs MIDI Shingetsu according to the data on the CD-ROM;
2 is a synthesizer that operates using MIDI standard signals;
13 is an amplifier, and 14 is a speaker.

Effects of the Invention As described above, the still image display and music performance device of the present invention provides a high-quality still screen and music performance suitable for viewing art paintings and the like. In particular, for music performance, by adopting a system in which the performance is performed by providing musical note data, the amount of necessary data can be significantly reduced, which is extremely advantageous in practice.
