Abstract
Abstract A video image apparatus which records an image corresponding to a video signal including synchronizing signals is disclosed. The apparatus includes a detector for detecting a lack of synchronizing signals and a controller responsive to the detector for inhibiting the record operation in order to cope satisfactorily with interruption of the input video signal. Preferably, the apparatus further includes a restart unit for restarting the recording operation from the position where the recording operation has stopped after the input video signal has been restored.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
A video image recording apparatus for recording an image corresponding to a video signal having synchronizing signals, comprising: input means for receiving said video signal having synchronizing signals; sample means connected to said input means for sampling the video signal, said sample means including a memory for storing sampled video signals representing a portion of said image; record means for recording an image corresponding to the output of said sample means simultaneously with sampling said video signals; detection means connected to said input means for detecting the synchronizing signals; and control means responsive to said detection means for inhibiting the recording operation of said record means when an absence of said synchronizing signals is detected.
Claim 2
Dependent Claim
115 words
A video image recording apparatus for recording an image corresponding to a video signal having synchronizing signals, comprising: input means for receiving said video signal having synchronizing signals; sample means connected to said input means for sampling the video signal, said sample means including a memory for storing sampled video signals representing a portion of said image; record means for recording an image corresponding to the output of said sample means simultaneously with sampling said video signals; detection means connected to said input means for detecting the synchronizing signals; and control means responsive to said detection means for inhibiting the recording operation of said record means when an absence of said synchronizing signals is detected.
Claim 3
Dependent Claim
43 words
A video image recording apparatus according to claim 1, wherein said record means includes: a recording head; and carrier means for carrying a record medium to said recording head, and wherein said control means inhibits operation of said head and said carrier means.
Claim 4
Dependent Claim
18 words
A video image recording apparatus according to claim 2, wherein said record head includes an ink jet head.
Claim 5
Dependent Claim
36 words
A video image recording apparatus according to claim 3, wherein said record means further includes: a drive circuit for driving said record head on the basis of the output of said memory of said sample means.
Claim 6
Dependent Claim
64 words
A video image recording apparatus according to claim 1, wherein said sample means further includes: a sample and hold circuit for sampling and holding the video signal; and an analog to digital converter for converting the signal sampled and held by said sample and hold circuit and for producing an output; and wherein said memory stores the output of said analog to digital converter.
Claim 7
Dependent Claim
31 words
A video image recording apparatus according to claim 5, wherein said memory has a capacity to store sampled video signals for one to several lines or columns of said video image.
Claim 8
Dependent Claim
45 words
A video image recording apparatus according to claim 6, wherein said sample means further includes: a digital to analog converter for converting the output of said memory and producing an output and wherein said record means stores the output of said digital to analog converter.
Claim 9
Dependent Claim
34 words
A video image recording apparatus according to claim 1, further including: restart means connected to said control means for restarting the recording operation of said record means after the recording operation has been inhibited.
Claim 10
Dependent Claim
71 words
A video image recording apparatus according to claim 8, wherein said restart means includes: first means for storing the sample position when said absence of the synchronizing signals has been detected; second means for identifying the location of the sample position; and third means for issuing an instruction to restart record operation when the sample position location identified by second means coincides with the sample position stored in said first means.
