A CPU 38 retrieves the reproduction control program from a header portion of a video disk. The CPU stores the program into a RAM 35. The CPU controls disk players 34a and 34b to reproduce video data from video disks, based on the program stored in a ROM 33 and the reproduction control program now stored in the RAM 35.

Video disk and video reproduction device which automatically extracts

When the data supply rate from the data storing unit 11 drops and the amount of data remaining in the buffer memory 21 decreases, the calculation circuit 25 determines a data reproduction speed at which reproduction should be performed, dependently on the amount of data in the buffer memory 21. Accordingly, the video reading circuit 23 is controlled to retrieve video data from the buffer memory 21 at a reduced reproduction speed. The monitor 13 reproduces a slow motion pictures, which leads to an enhancement of the buffer memory.

Video reproduction device

A microcomputer selects one of a plurality of drive units, and controls the selected drive unit to reproduce image data from a video disk located thereon. When a reproduction error occurs in the thus reproducing drive unit, the microcomputer selects another drive unit, and controls the drive unit to reproduce images. Accordingly, it is possible to always provide accurate images.

Image reproduction device for reproducing image data from video disks

A compact image karaoke device with only a small number of image disks which provides the impression of having a great many background images. Two players are provided for reading background images from image disks. Background images are selected from at least one image unit group corresponding to at least one image genre corresponding to selected song genre and are read by the two players and changed at random, for example, every 30 seconds. By editing the display of background images in this manner, a great number of background image series can be obtained for combinations of the background images. Images obtained and displayed corresponding particularly to the starting portion of the song are provided only on the number of images available. Therefore, even if a great number of songs are consecutively selected, a user will not feel as though the same images are being repeatedly shown.

Image karaoke device

When images of the image genre most suitable for the selected song are being reproduced (Yes in S14), the karaoke terminal picks up those image data from a channel over which they are transmitted. If images of that image genre are not being reproduced (No in S14), when the number of players presently playing is less than four (No in S19), a player that is not presently playing starts playing a video disk to reproduce images of that image genre in S20. When the number of players presently playing is equal to or greater than four, according to the image genre D and/or H reproducing status, a player that is not presently playing starts playing a video disk to reproduce images of image genre D or H that includes or is common to the most suitable image genre.

Interpolating processes for vertically aligned horizontal scanning lines are performed with respect only to red component video data so as to simplify the structure of an image processor and to decrease the number of components that are required for interpolation. Interpolation is always performed for the green component video data, which makes up a great deal of the luminance component. Even when only green is interpolated, 59% of the total luminance component of yellow is interpolated so that flicker is reduced to a practical level.

Image processor for producing even field video data based on odd field

To provide a device which can easily copy an image within a limited area of an original. A reading window is defined in a lower projecting portion of a housing which is L-shaped in side elevation, providing a visual recognition member. The visual recognition member allows the user to visually recognize the image to be copied over which the housing is placed. When a start button is depressed, a sensor is reciprocally moved by a wire. An image read by the sensor is printed on a tape by a print head. The printed head tape is fed by a tape feed roller operatively coupled by a gear train to a motor which also drives the wire through a gear train.

Copying device for producing a label

The invention provides a performance recording/reproducing apparatus including a playing information recording device, a data discrimination device and a data transfer device. The data discrimination device discriminates a specific channel of playing data, which needs correction or modification from the others all merged on one of the tracks of the playing information recording device. The data transfer device transfers data of the specific channel to another track. The apparatus thus efficiently corrects or modifies only data of the specific channel and accordingly completes recording of performance in a short while.

Performance recording/reproducing apparatus enabling correction or

The invention provides performance recording apparatus for separately recording plural event data, each corresponding to an electronic instrument, as plural channels of playing information onto playing information recorder. The apparatus includes channel converter for converting a channel discrimination code of newly received event data into another channel discrimination code, and merger for merging event data with the converted channel discrimination code with other event data which have already been recorded on the playing information recorder. Since any identical channel is not assigned to plural event data corresponding to different electronic instruments, playing information corresponding to plural channels is easily processed and stored on the playing information recorder.

Performance recording apparatus for recording information used to

The invention provides a metronome for electronic instruments, which has memory means, event data output means and control means. The control means instructs the event data output means to output code data for generating beat sound for a certain time period. The code data is outputted at pitches and volumes based on beat data and at time intervals according to tempo data both stored in the memory means. The metronomre of the invention outputs beat sound together with main sound for a tune, without any specific devices attached to electronic instruments.

Metronome for electronic instruments

Magnetic disc storage equipment for recording and reproducing signals on a magnetic disc comprising a carriage for shifting a magnetic head in a radial direction of the magnetic disc upon which is recorded signals on a respective divided sector of a track, a shifting bolt which is screwed with the carriage, a stepping motor which is interlocked with the shifting bolt and rotates the shifting bolt by a destined number of steps corresponding to a respective track gap to adjust the magnetic head at each track through the carriage, detecting means to detect signals which are read by the magnetic head at a desired track position, and shifting means to shift the magnetic head to an appropriate position based on the signals which are detected by the detecting means.

Magnetic disk storage equipment

A method of writing information on a magnetic disk having a multiplicity of concentric recording tracks on a recording surface thereof, each track having sectors each of which includes a sector-identification field, and a data field on which the information is written. Initially, a magnetic head is positioned at a first erase position away from a centerline of selected one of the tracks by a predetermined distance in one of radially inward and outward directions of the disk. After reading the sector-identification field of selected one of the sectors of the selected track, the magnetic head is activated to perform a first erasing operation on the data field of the selected sector. Then, the head is moved to a second erase position away from the centerline by a predetermined distance in the other radial direction, and is activated to perform a second erasing operation on the same data field, after the sector-identification field has been raised. The head is then moved to the centerline of the selected track, and activated to write the information on the erased data field, after the sector-identification field has been read.
