Abstract:
1. A motion image recording apparatus which comprises a processor mounting a multitasking OS, and records a plurality of screens of image data forming a motion image signal in a compressed manner in a recording medium, wherein a plurality of tasks to be executed by said processor includes a first task in relation to a compression process of image data, and a second task in relation to a recording process of compressed image data, said first task includes an adding process for adding, to a predetermined parameter value, a value corresponding to a size of the compressed image data equivalent to a first number of screens, every time that image data corresponding to said first number of screens is compressed, said second task includes a subtracting process for subtracting, from said predetermined parameter value, a value corresponding to a size of the compressed image data equivalent to a second number of screens, every time that compressed image data corresponding to said second number of screens is recorded, and said first task includes a changing process for changing a compression ratio of the image data such that said compression ratio becomes higher as said predetermined parameter value becomes larger; wherein, when another task is executed, the second task is interrupted each time that a transmission by the defined amount is completed.
