Claims

[Scope of utility model registration request]

(1) In a still image recording device that includes a recording device that can record multiple screen information via an intermediate memory that can write or read information for one field of a video signal, a vertical blanking period separated from the video signal. circuit means for identifying a specific field of the video signal based on a signal within the video signal; and circuit means for writing image information of the specific field into the intermediate memory based on an identification signal output from the circuit means; A still image recording device characterized in that a screen of one frame is constructed in a pseudo manner by reading out the specific field image information from the intermediate memory in a predetermined time relationship.

(2) If the specific field identification circuit means has an equivalent pulse or a vertical synchronization pulse within the vertical retrace period, it is reset by the pulse and oscillates in synchronization with the horizontal synchronization signal; An oscillation section that freely oscillates at a frequency slightly lower than the horizontal frequency when there is no pulse, and a vertical synchronization pulse detection section that can extract only the vertical synchronization pulse after integrating the signal within the vertical blanking period separated from the video signal. , a specific field detection section that detects the specific field by utilizing the fact that the positional relationship between the pulse train signal from the oscillation circuit and the vertical synchronization pulse from the vertical synchronization pulse detection section is different between even and odd fields; A still image recording device according to claim (1) of the utility model registration claim.
