Abstract:
A memory management method for simultaneously recording image data comprising n-pieces, n being an integer equal to or larger than 2, of image sequences having variable image sizes, said memory management method comprising:dividing an area of a memory into first to n/2-th memory address spaces by allocating addresses from ADstart[i] to ADend[i] to a i-th memory address space, respectively; using an area from one of ends of ADstart[i] and ADend[i] of the i-th memory address space toward one of a higher memory address and a lower memory address in the i-th memory address space as an area in which image data of a k-th image sequence are recorded; using an area from another of the ends of ADstart[i] and ADend[i] toward another of the lower memory address and the higher memory address in the i-th memory address space as an area in which image data of a k+1-th image sequence are recorded; and dynamically changing a boundary of the area of the memory for storing the image data of the k-th image sequence and the k+1-th image sequence.
