Abstract
Abstract A still image reproducing system includes reproducing structure for reproducing still image data recorded on a recording medium. Instructing circuitry is provided for issuing instructions to cause movement of a reproducing position of the reproducing structure. Circuitry is provided for measuring a time interval between the instructions issued by the instructing circuitry. Control circuitry is provided for selecting one of a plurality of operation modes of the reproducing structure according to the time interval measured by the measuring circuitry. The operation modes include a first mode in which still image data reproduced by the reproducing structure is muted, and a second mode in which still image data reproduced by the reproducing structure is not muted.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
A still image reproducing system comprising: a) reproducing means for reproducing still image data recorded on a recording medium; b) instructing means for issuing instructions to cause movement of a reproducing position of said reproducing means; c) means for measuring a time interval between the instructions issued by said instructing means; and d) control means for selecting one of a plurality of operation modes of said reproducing means according to the time interval measured by said measuring means, said operation modes comprising a first mode in which still image data reproduced by said reproducing means is muted, and a second mode in which still image data reproduced by said reproducing means is not muted.
Claim 2
Dependent Claim
114 words
A still image reproducing system comprising: a) reproducing means for reproducing still image data recorded on a recording medium; b) instructing means for issuing instructions to cause movement of a reproducing position of said reproducing means; c) means for measuring a time interval between the instructions issued by said instructing means; and d) control means for selecting one of a plurality of operation modes of said reproducing means according to the time interval measured by said measuring means, said operation modes comprising a first mode in which still image data reproduced by said reproducing means is muted, and a second mode in which still image data reproduced by said reproducing means is not muted.
Claim 3
Dependent Claim
17 words
The still image reproducing system according to claim 1, wherein said recording medium comprises a disk-like medium.
Claim 4
Dependent Claim
18 words
The still image reproducing system according to claim 1, wherein said recording medium comprises a magnetic recording medium.
Claim 5
Dependent Claim
16 words
The still image reproducing system according to claim 1, wherein instructing means comprises a jog dial.
Claim 6
Dependent Claim
40 words
The still image reproducing system according to claim 1, wherein said measuring means includes: A) a counter for counting a clock signal; and B) means for altering the count of said counter according to an instruction of said instructing means.
Claim 7
Dependent Claim
68 words
The still image reproducing system according to claim 1, wherein in said first mode said control means causes the still image data reproduced by said reproducing means to be muted while said reproduction position is being changed, and wherein in said second mode said control means causes the still image data reproduced by said reproducing means to be not muted even while said reproducing position is being changed.
Claim 8
Dependent Claim
34 words
The still image reproducing system according to claim 6, wherein said control means selects said second mode if said interval is comparatively short and selects said first mode if said interval is comparatively long.
Claim 9
Dependent Claim
111 words
Control apparatus for a reproducing system having a reproducing head, comprising: a) track moving request means for issuing request signals to cause a movement of the reproducing head to a desired track position; b) measuring means for measuring a time interval between request signals issued by said track moving request means; and c) control means for selectively executing one of a plurality of different operation modes according to the time interval measured by said measuring means, said operation modes comprising a first mode in which an output of the reproducing head is caused to be muted, and a second mode in which the output of the reproducing head is not muted.
Claim 10
Dependent Claim
111 words
Control apparatus for a reproducing system having a reproducing head, comprising: a) track moving request means for issuing request signals to cause a movement of the reproducing head to a desired track position; b) measuring means for measuring a time interval between request signals issued by said track moving request means; and c) control means for selectively executing one of a plurality of different operation modes according to the time interval measured by said measuring means, said operation modes comprising a first mode in which an output of the reproducing head is caused to be muted, and a second mode in which the output of the reproducing head is not muted.
Claim 11
Dependent Claim
35 words
The control apparatus according to claim 8, wherein said track moving request means issues request signals to cause the reproducing head to move over a plurality of tracks which comprise a plurality of concentric circles.
Claim 12
Dependent Claim
15 words
The control apparatus according to claim 8, wherein said request means comprises a jog dial.
