摘要:
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.

摘要:
A transfer method for transferring data between a digital still camera and a printer in direct communication with each other. The digital still camera stores an image file of an input image and a conversion file including conversion information for carrying out color conversion in a preset color space common to both the digital still camera and the printer. The method includes a first transfer step of transferring from the digital still camera to the printer the conversion file and a second transfer step of transferring the image file from the digital still camera to the printer. The printer carries out color conversion of and outputs the image of the image file transferred in the second transfer step using the conversion information included in the conversion file transferred in the first transfer step.
