1. A method for storing an image, the method comprising:
- dividing a memory into a plurality of memory regions having equal sizes, and allocating the memory regions having the equal sizes to a plurality of channels;
pre-recording image signals input through the channels in the memory regions, respectively, for a first time period or a second time period shorter than the first time period, when events occur;
counting an event occurrence number from the image signals for a predetermined time period;
reallocating the memory regions to the channels according to the event occurrence number and a recording state of the image signals in the memory regions; and
storing the image signals pre-recorded in the memory regions, in a storage.

Abstract
The inventive concept relates to a method for storing an image. The method includes: initially allocating an entire memory equally to a predetermined number of channels set to perform pre-recording for a first time period or a second time period shorter than the first time period when an event occurs; counting an event occurrence number from image signals input to the channels for a predetermined time period; and reallocating memory regions allocated to the respective channels, according to the event occurrence number and image signal storage states of the memory regions.

8. An apparatus for storing an image, the apparatus comprising:
-
at least one processor configured to implement; a controller which divides a memory into a plurality of memory regions having equal sizes, allocates the memory regions having the equal sizes to a plurality of channels, and pre-records image signals input through the channels in the memory regions, respectively, for a first time period or a second time period shorter than the first time period, when events occur; an event processor which counts an event occurrence number from the image signals for a predetermined time period; and a dynamic memory allocator which reallocates the memory regions according to the event occurrence number and a recording state of the image signals in the memory regions, wherein the controller stores the image signals pre-recorded in the memory regions, in a storage. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An apparatus for storing an image, the apparatus comprising:
-
at least one memory; and at least one processor configured to implement; a controller which divides the memory into a plurality of memory parts having equal sizes, allocates the memory parts having the equal sizes to a plurality of channels, and pre-records image signals input through the channels in the memory parts for different time periods, when events occur, respectively; an event processor which checks characteristics of the image signals input through the channels; and a dynamic memory allocator which changes an attribute of at least one of the channels or at least one of the memory parts to which the channels are allocated, respectively, according to a result of the characteristics checking. - View Dependent Claims (16, 17, 18, 19)
