There is provided an image processing apparatus for applying an adjusting process to an image including multicolor image signals. An image area including a pixel to be processed is extracted, and one representative signal value is generated from signal values corresponding to a plurality of colors of pixels included in the image area (S2501). A feature amount associated with the image area is calculated based on the representative signal value (S2503, S2505, S2511), and a substitute candidate pixel common to the plurality of colors is selected from the image area based on the calculated feature amount (S2512). Signal values of the pixel to be processed are substituted by new pixel values, which are calculated from the signal values of the pixel to be processed and signal values of the substitute candidate pixel.

In a print system for causing a printer to print an image on the basis of image data supplied from a portable communication apparatus by direct communication between the portable communication apparatus and the printer, the print function of the printer is obtained. When print conditions input by using the UI of the portable communication apparatus cannot be implemented by the print function of the printer, the portable communication apparatus requests a server to execute corresponding processing. A result processed by the server is received, and the printer is caused to print the image.

An image processing apparatus is configured to apply correction processing to image data having sharpness varying depending on an alignment direction of pixels. The image processing apparatus detects a feature quantity in an edge direction of the image data. The image processing apparatus sets an intensity of the correction processing based on correction intensity which is predetermined based on the sharpness varying depending on the alignment direction of the pixels, according to the detected feature quantity in the edge direction of the image data.

In an ink-jet printer, when a gray is expressed by mixing ink of a plurality of colors, there is a concentration in which a use amount of the ink is large. If the gray in an edge portion of a character has the concentration of the large ink use amount, a bleeding of the ink occurs and a thin portion of the character is sometimes damaged. If the gray in the character edge portion has the concentration of the large ink use amount, the gray in the character edge portion is changed to the white side by image correction, and the damage of the character thin portion caused due to the ink bleeding is prevented.
