Abstract: An image forming apparatus, such as a laser printer, ink jet printer, or a thermal transfer, which comprises a neural network. The apparatus improves image quality by reducing a zigzag included, e.g., in input image data, reducing the circuit size by reducing the number of bits having small weights for an input combination, and concurrently correcting the size of center, left and right picture elements in a predetermined window. The neural network outputs correction data for the size and position of the center dot in a window in response to an input of dot image data in a window or subdot pattern exposure data for the center dot. Additionally, the neural network uses any of the three values, +1, -1 and 0, for the coefficient of input combination for a hidden layer neuron, e.g., after a teacher pattern is learned. Further, the neural network outputs correction data for 3.times.N subblocks of picture elements obtained by dividing blocks of picture elements in the center, left and right of a window.

Abstract: A dividing unit divides image data into a plurality of blocks. An extracting unit extracts a feature index of a first color component and a feature index of a second color component in each of the blocks. A registration unit registers information about a correspondence between the feature index of a second color component and a change in the feature index for the first color component. A code embedding unit embeds a predetermined code into the image data, by changing the feature index of the first color component based on the feature index of the second color component, using the information registered.

Abstract: A halftone gradation processing method reduces or eliminates the discontinuous gradation reproduction in comparison with conventional error diffusion. A halftone gradation processing method includes obtaining a position and a pixel value of a target pixel in an input image, correcting the pixel value, selecting the closest threshold to the corrected pixel value from among usable thresholds assignable to the pixel value, calculating an error between the corrected pixel value and the selected threshold, and diffusing the error around the target pixel, the pixel value correcting being corrected by the diffused error, and the selected threshold being output to an output device which may handle the assigned thresholds.
