An image processing portion of an image reading apparatus includes an extraction portion that extracts color information, a management portion that manages management color information that is an estimated value of the color information based on a control signal, a determination portion that determines whether or not the color information matches the management color information, and a writing control portion that causes the storage portion to store the pixel data when it is determined that the color information matches the management color information and that does not cause the storage portion to store the pixel data when it is determined that the color information does not match the management color information. When the color information does not match the management color information, the management portion adjusts the management color information to match the color information.

An embodiment of the present disclosure provides a method for processing an image. The method comprise: determining weights corresponding to candidate colors for a target color based on an original color of a pixel in the image; selecting a target color of the pixel from the candidate colors based on the weights; and converting the original color of the pixel into the target color to obtain a target image. According to the embodiment of the present disclosure, by determining the weights of the candidate colors, the image can be converted into the target image comprising only the candidate colors, thereby using a limited number of candidate colors to represent the target image.

Examples of printing device calibration based on a lot code are described. In an example, a lot code of a print media is determined. Calibration parameters for a printing device are determined based on the lot code. The printing device is calibrated to print on the print media based on the calibration parameters.

A system generates a prediction model for makeup color matching. The system includes a data storage device and a modeling engine. The data storage device stores a plurality of color sets comprising a skin color set, a makeup color set, and a target color set. The modeling engine is coupled to the data storage device and configured to generate a prediction model and an output color set. The prediction model models generation of the target color set based on inputs from the skin color set and the makeup color set. The output color set approximates the target color set with a predictable accuracy.
