Software of a simple configuration checks whether an original image to be corrected is an image picture, and an image correction process based upon a formed histogram of the original image is not performed for an image different from the image picture. An image processing condition is set in accordance with the formed histogram to perform the image correction process for the original image. An image processing method judges from a shape of the formed histogram whether the original image is an image picture, and does not perform not perform the image correction process for the original image if it is judged that the original image is not an image picture.

Image processing method and apparatus and storage medium

There is provided a document processing system in which a print image is stored into a memory and can be handled as output data by forming a document. The system comprises: a memory to store document data in a bit map style; a converter for converting the document data including characters, figures, images, etc., based on the result of the document formation into data of bit map style to be stored into the memory; an image output device corresponding to a page description language; and a circuit for making the data of bit map style stored in the memory correspond to the data format of the page description language, suitable for the particular image output device. With this system, data of substantially the same style as that in the local printing characters can be obtained from an external printing system in accordance with a request of the user.

Document processing with flexible resolution and output style

According to an image processing method for performing color processing in accordance with a plurality of image objects, image data representing the plurality of image objects is input. The relationship between the plurality of image objects is analyzed. The plurality of image objects are grouped based on the result of analysis. The same color processing condition is set for the plurality of image objects belonging to the same group. Thus, the same color processing condition is set for the plurality of image objects divided from a single original image, thereby obtaining a high-quality output image.

Image processing method, image processing apparatus, and recording medium

An image-processing method for performing color matching using a source profile and an output profile, includes a step of correcting input image data, a step of calculating a feature quantity of an input image based on the corrected image data, a step of performing an image correction process on the input image data in accordance with a processing condition responsive to the feature quantity, and a step of performing a color matching process on the corrected input image data. The image-processing method is thus performed with the color matching process result taken into account.

Image-processing method, image-processing device, and storage medium

There is provided a document processing system in which a print image is stored into a memory and can be handled as output data by forming a document. The system comprises: a memory to store document data in a bit map style; a converter for converting the document data including characters, figures, images, etc., based on the result of the document formation into data of bit map style to be stored into the memory; an image output device corresponding to a page description language; and a circuit for making the data of bit map style stored in the memory correspond to the data format of the page description language, suitably for the particular image output device. With this system, data of substantially the same style as that in the local printing characters can be obtained from an external printing system in accordance with a request of the user.

A word processor capable of creating a formula during a document editing process by automatically setting a range of a formula in a document being edited with an instrument of a formula process start command and allowing a switching operation between the document editing process and the formula creating process to be easily made. This allows the formula to be edited on a block basis, thereby facilitating the editing operation such as modification, addition, or deletion of the formula in accordance with any editing of character trains or symbols inside and outside the formula in a well-balanced manner. The word processor is also capable of automatically defining the position, size, and form of a symbol in accordance with the length and form of an object to which the symbol is to be added, so that the position, size, and form of the symbol can be automatically accommodated in accordance with any change in the object to which the symbol is to be added without bothering an operator. The word processor is further capable of not only adding a symbol to an already input text, but also inputting paired symbols which are mutually spaced apart such as a pair of parentheses with a single input operation.
