Image sensing/playback apparatus, image data processing method, and data processing method

Abstract

The image sensing/playback apparatus has an image sensing device that senses an image of an object and obtains electrical image data, an input/output I/F that inputs/outputs image data from/to an external storage medium, and a system controller that sequentially performs a plurality of tasks, exclusively controlling the input/output I/F and 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 one unit data amount is one of the first unit data amount that is large and the second unit data amount that is smaller than the first unit data amount. If an instruction is given to perform the second task of the plurality of tasks while the first task, different from the second task, is performed to process the first unit data amount at a time, the system controller sets the unit data amount of one with a higher priority of the first and second tasks to the first unit data amount and the unit data amount of the other task with a lower priority to the second unit data amount to perform the tasks.
