Zusammenfassung:A method, non-transitory computer readable medium, and apparatus for adjusting a light intensity of a printhead are disclosed. For example, the method receives an image comprising a plurality of pixels, calculates a correction factor for each one of a plurality of pixels of the image by applying a filter to each one of the plurality of pixels of the image and summing a contribution of the light intensity of each one of a plurality of surrounding pixels to a pixel being analyzed to calculate an overlap value and comparing the overlap value to a development threshold range and adjusts the light intensity of a light source of the printhead in accordance with the correction factor of each one of the plurality of pixels of the image that require toner.
