Image storing device including an inhibiting function
First Claim
1. An image storing device, comprising:
- (a) input means for inputting a motion video signal;
(b) a memory into which the motion video signal inputted from said input means can be written;
(c) writing address control means for cyclically specifying writing addresses of said memory to which the motion video signal is written; and
(d) inhibiting means for inhibiting a part of addresses of said memory from being specified by said writing address control means,wherein said writing address control means skips the part of addresses to continuously write the motion video signal to addresses before and after the part of addresses when said inhibiting means operates.

Abstract
A memory capable of memorizing a video signal has part of its address area into which an information signal is inhibited from being written. A writing address controller for cyclically specifying writing addresses of the memory cyclically specifies writing addresses in the remaining address area except for the part of address area to allow a plurality of different moving picture scenes to be memorized in the one and same memory.
For according to a large capacity main memory, a sub-memory is interposed to access to the main memory with a predetermined information amount being as the unit, thereby facilitating address management of the main memory as well as improving a utilizing effeciency of the main memory.

7. An image storing device comprising:
-
(a) a memory capable of storing a video signal; (b) recording means for recording a video signal read from said memory on a recording medium; (c) writing address control means for cyclically specifying writing addresses of said memory; (d) inhibiting means for inhibiting a video signal from being written into part of addresses of said memory, wherein said writing address control means cyclically specifies writing addresses for the remaining addresses except for said part of addresses when said inhibiting means inhibits a video signal from being written into said part of addresses; and (e) releasing means for responsively releasing writing inhibition set by said inhibiting means which inhibits a video signal from being written into said part of addresses upon completing recording of a video signal read out from said part of addresses by said recording means.

8. An image storing device, comprising:
-
(a) a memory capable of storing a video signal; (b) writing address control means for cyclically specifying writing addresses of said memory; (c) output means for outputting a video signal read from said memory; (d) recording means for recording a video signal outputted from said output means on a recording medium, wherein said output means controls said recording means so as to operate said recording means while a video signal is being outputted; and (e) inhibiting means for inhibiting a video signal from being written into part of addresses of said memory, wherein said writing address control means cyclically specifies writing addresses for the remaining addresses except for said part of addresses when said inhibiting means inhibits a video signal from being written into said part of addresses.

9. An image storing device comprising:
-
(a) a memory capable of storing a motion video signal; (b) writing means including address control means for specifying writing addresses of said memory to write the motion video signal into memory; (c) inhibiting means for inhibiting said writing means from specifying a part of addresses of said memory; and (d) read-out means including read-out address control means for specifying read-out addresses of said storage area of said memory, said read-out means being capable of reading a motion video signal, which has been previously stored in said part of addresses before the writing addresses are inhibited from being specified by said inhibiting means, during a writing operation of said writing means. - View Dependent Claims (10)

11. An image storing device comprising:
-
(a) a memory capable of storing a video signal; (b) writing means including writing address control means for specifying writing addresses of said memory; (c) inhibiting means for inhibiting said writing means from specifying writing addresses of a predetermined area of said storage area of said memory; (d) read-out means including read-out address control means for specifying read-out addresses of said memory; and (e) cancel means for cancelling inhibition by said inhibiting means in response to completion of a read-out operation of a video signal in the part of addresses by said read out means.
