IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18115456 titled 'IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
Simplified Explanation
The abstract describes an image processing device that identifies defect candidate pixels by analyzing phase information of pixels with respect to different modulation frequencies of a sensing light source. It then corrects the phase of the identified defect candidate pixels.
- Decision pixel manager sets a decision area for defect candidate pixels and determines first and second decision pixels based on phase information at different modulation frequencies.
- Target pixel determiner calculates the phase difference between the first and second decision pixels and identifies defect candidate pixels based on a predetermined reference value.
- Phase corrector adjusts the phase of the defect candidate pixels based on the phase difference.

Original Abstract Submitted
An image processing device including: a decision pixel manager for setting a decision area for a defect candidate pixel, and determining a first decision pixel and a second decision pixel, based on first phase information of pixels included in the decision area with respect to a first modulation frequency of a sensing light source among the pixels; a target pixel determiner for calculating a phase difference between the first decision pixel and the second decision pixel, based on second phase information of the pixels with respect to a second modulation frequency of the sensing light source, and determining the defect candidate pixel as a target pixel, corresponding to that the phase difference exceeds a predetermined reference value; and a phase corrector for changing a phase of the target pixel, based on the phase difference.
