Image processing apparatus for performing random mask process |
摘要 |
An image processing apparatus includes a circuit for correcting a first image data of a target pixel corresponding to a correction amount, a circuit for generating a third image data on the basis of the second image data and a preset threshold value, the third image data having a gradation value less than one of the second image data, a circuit for comparing the second image data with the third image data to output a difference value therebetween, and a circuit for deriving the correction amount. based on the difference value to randomly diffuse the difference value to the peripheral portion of the target pixel and supplying the correction amount to the correcting circuit.
