ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an image processing method and apparatus and, more particularly, to an image processing method and apparatus for performing color processing.
Image processing apparatuses which perform color matching processing for correcting the difference between color representation capabilities on a plurality of image output devices are recently on the market. In such apparatuses, a single color matching is applied to a single output image, for example.
In the color matching processing in the conventional image processing apparatuses, however, in a case where a plurality of objects having different attributes are included in a single output image, it is not possible to perform color matching processing suitable for each object. Therefore, if the plurality of objects which are processed with an identical color matching processing are outputted as a single image to a plurality of image output devices, a problem of deterioration of the output image quality (e.g., color, density balance of the overall image, brightness) arises.
SUMMARY OF THE INVENTION
The present invention has been made in consideration of the above situation, and has as its object to provide an image processing method and apparatus capable of obtaining a high-quality output image by performing color matching processing suitable for each object on the basis of the color representation capability of a source device which generates color image data of the object, depending upon a user's utilization of the image.
According to one aspect of the present invention, the foregoing object is attained by providing an image processing apparatus comprising: setting means for setting a source device in accordance with a manual instruction in correspondence with a type of an object image; determination means for determining the type of the object image which includes input image data; and color matching means for performing color matching processing by using a profile corresponding to the source device set by the setting means in correspondence with the type of the object image determined by the determination means.
In the above apparatus, the setting means preferably realizes to set source devices for types of a plurality of object images, respectively, in accordance with a manual instruction. Or, the color matching means preferably realizes to perform a first color matching processing corresponding to the source device and a second color matching processing corresponding to an output device as the color matching processing. And the second color matching processing is preferably based on the color matching method corresponding to the type of the object image determined by the determination means.
Further, the above apparatus may be further comprises color processing means for performing color processing on the basis of output characteristics of an output device for outputting an image corresponding to the type of the object image.
According to another aspect of the present invention, the foregoing object is attained by providing an image processing method comprising the steps of: setting a source device in accordance with a manual instruction in correspondence with a type of an object image; determining the type of the object image which includes input image data; and performing color matching processing by using a profile corresponding to the set source device in correspondence with the determined type of the object image.
It is another object of the present invention to provide an image processing method and apparatus in which color matching processing for each object can be easily set depending upon a user's utilization of the image including the object.
According to one aspect of the present invention, the foregoing object is attained by providing an image processing apparatus comprising: storage means for storing plural pieces of information showing correspondence between types of a plurality of object images and color matching methods for each type of output images; setting means for setting a type of an output image in accordance with a manual instruction; input means for inputting an object image included in the output image; determination means for determining a type of the object image; and color matching means for performing color matching processing on the object image on the basis of the type of the object image determined by the determination means and the information, corresponding to the type of the output image set by the setting means, stored in the storage means.
According to another aspect of the present invention, the foregoing object is attained by providing an image processing method comprising the steps of: storing plural pieces of information showing correspondence between types of a plurality of object images and color matching methods for each type of output image into a storage medium; setting a type of an output image in accordance with a manual instruction; inputting an object image included in the output image; determining a type of the input object image; and performing color matching processing on the object image on the basis of the determined type of the object image and the stored information corresponding to the set type of the output image.
The invention is particularly advantageous since it is possible to perform color matching processing suitable for each object on the basis of the color representation capability of a source device which generates color image data of the object, depending upon a user's utilization of the image including the object, thereby obtaining a high-quality output image.
Further, it is possible to set color matching processing for each object depending upon a user's utilization of the image including the object.
Other features and advantages of the present invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the figures thereof.
