Abstract A video signal from a camera portion (1) is supplied as moving picture data to a moving picture recording portion (2) where the video signal is recorded with a time code attached thereto. The video signal from the camera portion (1) is also supplied to a series circuit of frame memories (4, 5). The video signal is read from the memories (4, 5) every frame interval and supplied to a comparison calculation portion (6) in which a change in scene is detected by comparison calculation (judgment of existence of correlation) of video signals having a time difference of one frame therebetween, and the change in scene detection information is supplied to a controller (3). When a change in scene is detected, a one-frame portion of the video signal is read from memory under the control of the controller (3) and the read signal is supplied to and recorded by a still picture recording portion (7). The one-frame portion of video signal is recorded together with a time code which is attached to the one-frame portion of video signal when it is recorded by the moving picture recording portion (2).
Apparatus for recording image data, the apparatus comprising: first recording means (2) for recording a video signal as moving picture data together with address information; means (6) for detecting a change in scene from an interframe or interfield correlation of said video signal; and second recording means (7) for recording, when a said change in scene is detected by said detecting means (6), a one-screen portion of said video signal, as still picture data, together with said address information corresponding thereto.
Claim 2
Dependent Claim
37 words
Apparatus according to claim 1, wherein said one-screen portion of video signal recorded as still picture data is at least one of the first and last video signals of each cut picked up by a video camera.
Claim 3
Dependent Claim
50 words
Apparatus according to claim 1 or claim 2, comprising means for decreasing the data quantity of said still picture data recorded by said second recording means (7), thereby to make the size of the image of the still picture smaller than the size of the image of the moving picture.
Claim 4
Dependent Claim
32 words
Apparatus according to claim 1, claim 2 or claim 3, comprising means for recording said still picture data in a specific position on a recording medium for recording said moving picture data.
Claim 5
Dependent Claim
28 words
Apparatus according to claim 1, claim 2 or claim 3, which is operative to record said moving picture data and said still picture data on separate recording media.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 5, which is operative to record said moving picture data and said still picture data on separate recording media disposed within the same housing.
Claim 7
Dependent Claim
26 words
Apparatus according to any one of the preceding claims, wherein a video camera (1) and said first and second recording means (2, 7) are formed integrally.
