    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.

    摘要: Upon outputting halftone image data to an output device, density transformation is prevalently done to improve image quality. Density transformation corresponds to linear gamma correction, and cannot correct any color fog and the like of a photo image. Hence, lightness/color difference information of halftone image data is acquired on the basis of low-frequency components of frequency data obtained by transforming halftone image data into spatial frequency components, and a lightness/color difference transform amount of the halftone image data is set on the basis of the acquired lightness/color difference information.
