Abstract
Abstract A video signal recording apparatus in which still image data picked-up by image pick-up means (1) are recorded on a predetermined record medium (14), comprises a memory (32) for storing the still image data corresponding to a plurality of still images, wherein after still image data derived from the image pick-up means (1) at an arbitrary timing have been sequentially stored in the memory (32), the stored still image data are read out from the memory (32) and sequentially recorded on the record medium (14). Furthermore, an identifying signal indicative of an end portion of each still image signal may be on an end portion of the data searched on the record medium (14), so that the end portion can be subsequently detected.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
87 words
A video signal recording apparatus in which still image data picked-up by image pick-up means (1) are recorded on a predetermined record medium (14), the apparatus comprising a memory (32) for storing said still image data corresponding to a plurality of still images, wherein after still image data derived from said image pick-up means (1) at an arbitrary timing have been sequentially stored in said memory (32), said stored still image data are read out from said memory (32) and sequentially recorded on said record medium (14).
Claim 2
Dependent Claim
15 words
Apparatus according to claim 1 wherein said still image data are a digital video signal.
Claim 3
Dependent Claim
30 words
Apparatus according to claim 1 further comprising a still image recording switch (42) which enables a continuous analogue video signal to be recorded as a digital video signal when operated.
Claim 4
Dependent Claim
21 words
Apparatus according to claim 1 wherein said image pick-up means (1) is a charge coupled device of a full-pixel read-out type.
Claim 5
Dependent Claim
23 words
Apparatus according to claim 1 wherein said memory (32) is a frame memory (32) which can store a video signal of three frames.
Claim 6
Dependent Claim
105 words
Apparatus in which a continuous video signal is sequentially recorded as a real moving picture, and a still image signal, which results from said video signal at an arbitrary timing, is recorded on a recording medium, the apparatus comprising means for recording an identifying signal indicative of an end portion on or near the end portion of a still image signal recording portion on said recording medium, wherein when a new still image signal is recorded on said recording medium, said end portion is detected by said identifying signal and said still image signal is recorded on a recording portion next to said end portion.
Claim 7
Dependent Claim
20 words
Apparatus according to claim 1 or 2 wherein said still image data of one frame are recorded on 228 tracks.
Claim 8
Dependent Claim
26 words
Apparatus according to claim 7 wherein said identifying signal is recorded in the last 20 tracks of 228 tracks forming a video signal of one frame.
Claim 9
Dependent Claim
27 words
Apparatus according to claim 1 further comprising bit reduction means (31) for reducing a redundancy of a digital video signal to be stored in said memory (32).
Claim 10
Dependent Claim
22 words
Apparatus according to claim 1 wherein a dummy video signal is recorded on a video signal area of said record medium (14).
Claim 11
Dependent Claim
22 words
Apparatus according to claim 11 wherein said dummy video signal has no video information and is composed only of a synchronizing signal.
Claim 12
Dependent Claim
29 words
Apparatus according to claim 6 wherein track number data are recorded on each track together with said still image digital video signal, in order to detect the last track.
Claim 13
Dependent Claim
23 words
Apparatus according to any one of the preceding claims wherein said recording apparatus utilizes a signal format of an 8-mm video tape recorder.
