Methods and systems for processing low resolution images via error diffusion

A system for processing a low resolution image, said system comprising:

• a processor;
• a data bus coupled to said processor;
• and
• a computer-usable medium embodying computer program code, said computer-usable medium being coupled to said data bus, said computer program code comprising instructions executable by said processor and configured for:
• converting a low-resolution binary output pixel to predetermined number of interpolated sub pixel values;
• comparing each interpolated sub-pixel value among said predetermined number of interpolated sub-pixel values with a threshold to generate a scaled slow-scan output pixel utilizing a low resolution error diffusion algorithm;
• adjusting said threshold level to produce a threshold adjustment and prevent said scaled slow-scan output pixel from firing about said low resolution binary output pixel within a highlight region;
• and
• distributing and storing a slow scan error with respect to said scaled slow-scan output pixel via an error diffusion filter coefficient within an error buffer without additional memory to improve image processing throughput rate.

A non-transitory processor-readable medium storing computer code representing instructions to cause processing of a low resolution image, said computer code comprising code to;

• convert a low-resolution binary output pixel to a predetermined number of interpolated sub pixel values;
• compare each interpolated sub-pixel value among said predetermined number of interpolated sub-pixel values with a threshold to generate a scaled slow-scan output pixel utilizing a low resolution error diffusion algorithm;
• adjust said threshold level to produce a threshold adjustment and prevent said scaled slow-scan output pixel from firing about said low resolution binary output pixel within a highlight region;
• and
• distribute and store a slow scan error with respect to said scaled slow-scan output pixel via an error diffusion filter coefficient within an error buffer without additional memory to improve image processing throughput rate.
