Abstract
An image processing apparatus for outputting image data to a printing unit, including an input receives data input from an external unit, an generator generates pixel image data in accordance with the input data, stores the pixel image data, converts the resolution of the pixel image data, and an outputs the pixel image data whose resolution has been converted. In the apparatus the image data generator determines the resolution of the pixel image data when it is stored in accordance with the memory capacity.
Claims12
An image processing apparatus for outputting image data to a printing unit, comprising:
- input means for inputting data from an external unit;
- image data generating means for generating pixel image data in accordance with the input data;
- memory means for storing the pixel image data;
- resolution converting means for converting a resolution of the pixel image data;
- and
- output means for outputting the pixel image data whose resolution is converted by said resolution converting means,
- wherein the image data generating means determines the resolution of the pixel image data when it is stored into the memory means in accordance with a memory capacity of the memory means.
A method of generating pixel image data which is printed by a printing unit, comprising the steps of:
- inputting data from an external unit;
- generating and outputting pixel image data whose resolution is determined by a size of memory which is constructed so as to store the pixel image data;
- and
- converting, if necessary, the resolution of the pixel image data stored in the memory in a manner such that the resolution of the output pixel image data is independent on the resolution determined in the pixel image data generating step.
