Patent ID: 8363263

Claim:
An image processing apparatus that scales image data, the image data generated by reading a document using a reading unit, by performing resolution conversion processing on the image data, the apparatus comprising: a detector that detects attributes of the image data generated by the reading unit; an attribute data generator that generates attribute data based on a result of detection performed by the detector; an image resolution converter that performs image resolution conversion processing on the image data of a pixel of interest; and an attribute resolution converter that performs attribute resolution conversion processing on the attribute data of the pixel of interest, the attribute resolution converter assigning attribute data identical to the attribute data before being subjected to the attribute resolution conversion processing as the attribute data for the pixel of interest following the attribute resolution conversion processing, and assigning the attribute data after being subjected to the attribute resolution conversion processing as the attribute data for neighboring pixels to the right and left of the pixel of interest following the attribute resolution conversion processing.
