An image processing system comprises: a terminal device that is provided with a display part; and an image processing device that outputs screen data to the terminal device, thereby enabling the display part to display a screen based on the screen data. The image processing device includes: a storage part in which multiple types of the screen data corresponding to respective screen sizes are stored; a screen information obtaining part that obtains information relating to the screen size of the display part; a screen data selecting part that selects the screen data corresponding to the screen size smaller than the screen size of the display part from among the multiple types of the screen data based on the information obtained by the screen information obtaining part; and an output part that outputs the screen data selected by the screen data selecting part to the terminal device.

An image forming apparatus includes a document reader, a storage for storing image data, an image output unit and a control unit. The control unit includes a display image generator for generating a display image, a display panel and a control unit-side controller having a function of presenting the display image based on the image data input in a preview representation and an output processing function of implementing an output process. As the output processing function, two schemes are provided: a first output scheme wherein, when image data has been input through the input unit, the images are output after displaying the images to be output in a preview representation on a display panel, and a second output scheme wherein, when image data has been input through the input unit, the image is directly output without displaying the image to be output in a preview representation on the display panel.

An image recording apparatus generates a reduced image by reducing an image, generates a first cutout image by cutting out a part of the image before the reduction, performs processing for image recording involving writing into a memory on the reduced image and performs recording processing for recording the processed image, presents a first display by outputting an image based on the reduced image to a display unit, presents an enlarged display larger than the first display by outputting an image based on the first cutout image to the display unit during the recording processing, and does not perform specific processing involving reading or the writing of data from or into the memory at least when the enlarged display is ongoing during the recording processing.

An image processing method for processing a display image includes using an image forming apparatus which includes a position detector detecting a position of contact with a display screen and forms an image on a recording medium based on a display image displayed on the display screen. The display image includes an object image indicative of an object for an image formation and a medium image indicative of the recording medium, and the image processing method includes modifying magnification of the object image with respect to the medium image, without modifying the medium image, based on contact positions of two points detected by the position detector.

An image reading unit reads a source document image in 600 dpi, and a resolution conversion unit converts the resolution of the image to 75 dpi. An inclination detection unit detects inclination of the source document image. When a character conversion unit is to execute character recognition after cropping, a mode setting unit sets a quality-first mode. The inclination correction unit corrects the inclination of the image of 600 dpi, according to the inclination of the source document image detected by the inclination detection unit. A document image clipping unit clips out the source document image, and the resolution conversion unit converts the resolution of the source document image to 200 dpi. Thereafter, the character conversion unit executes the character recognition.

A display control method includes the steps of obtaining a first preview image resolution for checking a printing layout, obtaining a second preview image resolution for checking a spot color printing portion where the spot color printing is carried out, and displaying a spot color preview image for checking the spot color printing portion by using a resolution based on the first preview image resolution and the second preview image resolution. The first preview image resolution is calculated and obtained based on a print setting included in the print data and on a size of a region where display is carried out in the preview image displaying step, and the second preview image resolution is calculated and obtained based on a drawing command included in the print data and on the size of the region where display is carried out in the preview image displaying step.

In a case where an image processing apparatus and a terminal display screens in an associated manner, if the terminal receives a user operation in a state where an enlarged screen is displayed only on the terminal, and the terminal transmits information about the operation as it is to the image processing apparatus, processing not intended by the user may possibly be performed. Therefore, when the terminal receives a user operation in a state where an enlarged screen is displayed only on the terminal, the terminal does not transmit the operation information as it is to the image processing apparatus.

A display panel driver includes a scaler circuit performing image enlargement processing on input image data corresponding to an input image to generate -times enlarged image data corresponding to an -times enlarged image (is a number larger than one which cannot be represented as 2.sup.k); and a driver section driving a display panel. In calculating a pixel value of a target pixel of the -times enlarged image, the scaler circuit generates enlarged image data including 2.sup.n-times enlarged image data corresponding to a 2.sup.n-times enlarged image obtained by enlarging the input image with an enlargement factor of 2.sup.n (n is the smallest integer determined so that 2.sup.n is larger than ), and calculates the pixel value of the target pixel from the 2.sup.n-times enlarged image data through interpolation processing of pixel values of pixels of the 2.sup.n-times enlarged image corresponding to the target pixel of the -times enlarged image.

A display control apparatus includes, a reception unit that receives an operation on a display object displayed in a display area, a changing unit that changes the display area to a second size smaller than a first size, and a control unit that controls to, in a case where the operation is not received while the display area is displayed in the first size, when the display area is changed from the first size to the second size, display a first range of the display object, and in a case where the operation is received while the display area is displayed in the first size, when the display area is changed from the first size to the second size, move the display object to display a second range.
