Resolution conversion method and apparatus

A data processing apparatus comprising:

• input means for inputting data of a first resolution;
• converting means for converting the data of the first resolution into data of a second resolution higher than said first resolution by using a first conversion pattern table;
• and
• reducing means for reducing the data of the second resolution which was converted by said converting means,
• wherein said reducing means reduces the data of the second resolution by a thinning process.

A data processing apparatus comprising:

• input means for inputting character code data and image data;
• developing means for developing said input character code data into bit map data of a first resolution;
• converting means for converting the input image data into image data of the first resolution by using a conversion pattern table, in a case where the resolution of the input image data is not equal to the first resolution;
• and
• reducing means for reducing the bit map data of the first resolution which was obtained by said developing means and the image data of the first resolution which was obtained by said converting means.

A data processing apparatus comprising:

• data input means for inputting character code data and image data;
• magnification input means for inputting a variable magnification of an output image;
• developing means for developing the input character code data into data of a first resolution;
• first processing means for variably magnifying the data of the first resolution which was derived by said developing means into the data of the magnification which was input from said magnification input means;
• and
• second processing means for performing a data converting process to the magnified data so that the output image is an image of the magnification which was input from said magnification input means in consideration of a resolution of an output apparatus.

A data processing method comprising:

• an inputting step of inputting data of a first resolution;
• a converting step of converting the data of the first resolution into data of a second resolution higher than said first resolution by using a first conversion pattern table;
• and
• a reducing step of reducing the data of the second resolution which was converted by said converting step,
• wherein, in said reducing step, the data of the second resolution is reduced by a thinning process.
