Abstract
A method and apparatus for image processing, in which coded recording information is developed into bit image data in units of given areas. Each area has a size which is an integer multiple of the height of the record head. In addition, the recording information can be managed in units of record heads, and coloring agents, thereby reducing recording processing time. Further, unnecessary initialization is avoided because it is first checked to determine if any information is present within the width of the corresponding recording head, and only initializes if necessary.
Claims10
An image processing method comprising the steps of:
- providing a record head having a record height;
- receiving coded recording information in units of pages;
- developing the recording information into bit image data in units of areas, each said unit of area having a height corresponding to an integer multiple of the record height of said record head;
- recording the developed bit image data;
- storing information in a table, the information corresponding to an area where the bit image data for recording is present, the information in the table being stored in units of the record height of said record head;
- and
- controlling a recording operation of said record head according to the table information.
An image processing apparatus comprising:
- record means for recording an image, said recording means comprising a recording head;
- reception means for receiving coded recording information in units of pages;
- development means for developing the recording information into bit image data in units of areas each having a height corresponding to an integer multiple of a height of said record head;
- storage means for storing information in a table, the information corresponding to an area where the bit image data for recording is present, the information in the table being stored in units of the height of said record head;
- and
- control means for controlling a recording operation of said record head according to the information in the table.
