Image processing apparatus, image processing method employed by the same, and non-transitory recording medium storing computer readable image processing program

摘要

An image processing apparatus includes: an image input unit which inputs image data per page; a sub-memory unit which stores the image data input from the image input unit; an encoding unit which encodes the image data stored in the sub-memory unit; a main memory unit which stores the image data encoded by the encoding unit; a non-volatile storage unit which stores the encoded image data stored in the main memory unit; and a processor which executes processing of discriminating a memory size of the main memory unit and the sub-memory unit and switching between first input processing and second input processing to be executed in accordance with the discriminated memory size of the main memory unit and the sub-memory unit.

1. An image processing apparatus comprising:
an image input unit which inputs image data per page; a sub-memory unit which stores the image data input from the image input unit; an encoding unit which encodes the image data stored in the sub-memory unit; a main memory unit which stores the image data encoded by the encoding unit; a non-volatile storage unit which stores the encoded image data stored in the main memory unit; and a processor which executes processing of discriminating a memory size of the main memory unit and the sub-memory unit and switching between first input processing and second input processing to be executed in accordance with the discriminated memory size of the main memory unit and the sub-memory unit, wherein the first input processing is processing which stores in the sub-memory unit a part of a single page's worth of the image data input by the image input unit, secures in the main memory unit a memory area capable of storing the maximum capacity of the single page's worth of the image data to store the image data stored in the sub-memory unit and encoded by the encoding unit, and secures a memory area capable of storing the maximum capacity of a next single page's worth of image data in the main memory unit before storing the image data stored in the main memory unit into the non-volatile storage unit, and the second input processing is processing which secures in the sub-memory unit a memory area capable of storing the maximum capacity of the image data per page input by the image input unit, temporarily stores image data formed by encoding a part of the image data stored in the sub-memory unit into the main memory unit, stores the temporarily stored image data into the non-volatile storage unit, and then erases the temporarily stored image data.
