Abstract:
1. An image sensing/playback apparatus comprising: an image sensing device that senses an image of an object and obtains electrical image data; an input/output unit that inputs/outputs data including image data from/to an external storage medium; a controller that sequentially performs a plurality of tasks, having respective priorities decided in advance, while giving an opportunity to switch between the plurality of tasks after processing of one unit data amount of data, the plurality of tasks exclusively controlling said input/output unit when being executed, wherein the one unit data amount is one of a plurality of different data amounts to be processed in one operation, and if an instruction is given to perform one of the plurality of tasks while at least another task is performed, said controller sets one unit data amount of a task with a higher priority of the tasks to be performed to a larger data amount and one unit data amount of a task with a lower priority to a data amount smaller than the data amount of the task with the higher priority to perform the tasks, and further wherein said controller sequentially performs as the plurality of tasks an input task of inputting one frame image data and an output task of outputting one frame image data, and divides the one frame image data of each of the input task and the output task so that a divided data amount of the one frame image data of one of the input task and the output task with the higher priority is larger than a divided data amount of the one frame image data of the other of the input task and the output task with the lower priority.
