Abstract: In an encoding unit 100 for encoding a motion image are provided a corrector 121 scene determiner 122, correction data generator 123, and scene change detector 124. The scene change detector 124 detects a scene change in a motion image based on a differential image during encoding, and the detection result is input to the scene determiner 122. The scene determiner 122 determines details of the scene of an image after a scene change using a predicted image from the movement compensator 116, and the correction data generator 123 determines the correction method based on the result of the scene determination. The corrector 121 executes corrections by the set correction method until a next scene change is detected. In this way the correction method is updated only when a scene change is detected, thereby executing suitable correction and reducing the quantity of calculation necessary for correction.

Abstract: A display apparatus which has a mirror with a free curved reflective surface of which curvature fluctuates with inflection points, a liquid crystal display (LCD), a back light and a polarizer. Light of an image which was modulated by the LCD is reflected by the free curved reflective surface and passes through the polarizer. Then, the light is directed to an optical pupil. Since the curvature of the free curved reflective surface fluctuates with inflection points, curvature of field and distortion can be corrected properly, and an image of high quality can be formed.

Abstract: In case of transmitting a document file such as a PDF file to a printer without converting it into print data, a PC extracts from the document file to be printed information to be accessed when starting an analysis of the document file and transmits the information to the printer. The PC extracts a specified data from the document file and transmits it to the printer each time when the specified data is requested by the printer.

Abstract: Upon reception of a data transmission request, an image input device 1 searches for transmission means available for transmission to a destination, such as transfer to FTP server or transmission by e-mail, and lists all the extracted available transmission means. Image input device 1 then creates a selection menu executed as an applet for receiving a selection of transmission methods from the destination. The destination can use the selection menu acquired from image input device 1 to designate the priority order of desired transmission means and a file name in reception of transmitted data. The selection menu thus created is transmitted to the image input device 1.

Abstract: In image processing of a document having image data of a document including an image with character images on a background image, the character images and the background image thereof are separated. First, areas in correspondence to the character images from the image data are extracted, and character code data are generated based on the extracted areas in the image data. On the other hand, the character image in the image data is replaced with the background image. The character images are reproduced with reference to the character code data at the positions of the character images. On the other hand, the original character images are deleted from the image data. The character images on the background image is complemented based on the background image data. Then the character images based on the character code data and the background image thereof are synthesized.

Abstract: A driving controller is adapted for controlling driving of a plurality of driving units physically connected with one another, at least one of which includes a driving member frictionally engaged with a driven member. It is detected whether the driven member is being driven at a predetermined time. The unit including the driving member and another driving unit are driven at a predetermined timing when the detecting circuit detects the driven member is not driven at the predetermined time. The driven member and the driving member can be easily released from an adhered state.

Abstract: An image forming apparatus such as a copier and an air conditioner communicate with one another in a network. The air conditioner provides information regarding ambient temperature and/or humidity to the image forming apparatus. Based upon this information, the image forming apparatus selectively activates systems within the apparatus that regulate its internal temperature and humidity levels, to thereby achieve power savings. The image forming apparatus provides information regarding its operation state to the air conditioner. The air conditioner uses this information to adjust its heating or cooling operations to compensate for the heat generated by the image forming apparatus when it is operating.

Abstract: A tandem-type color image forming apparatus forms an image in a monochrome mode or in a full color mode. The apparatus has a controller which delays an image forming operation for a predetermined period of time when a color mode is switched from the monochrome mode to the full color mode during different images are continuously formed.

Abstract: Disclosed is a printing system having a data processing apparatus on which printer driver software capable of setting various kinds of print conditions is installed, and a printer for performing a printing operation based on print job data transmitted from the data processing apparatus. The printer driver software provides a user with a setting screen on which various user-selectable setting options for printing are displayed and can visually disable at least one of the setting options from the setting screen based on information about the state of the printer acquired from the printer. The information on the state of the printer includes information on the remaining amount of a consumable item loaded in the printer or an optional device connected to the printer, information on the size of a recording medium loaded in the printer, or information as to whether the optional device is connected to the printer.

Abstract: In accordance with an image processing method, a data region is detected from input image data. The input image data is rotated in accordance with inclination of an image. Determination is made whether the data region of rotated image data protrudes from an image area of the input image data. When detection is made of protruding, the smallest area including the data region is extracted from the rotated image data. When the data region of the rotated image data protrudes from the image area of the image data previous to rotation, the smallest region including the data region of the rotated image data is extracted from the rotated image data. Therefore, loosing information from image data subjected to rotational correction can be prevented. Also, the amount of image data subjected to rotational correction can be minimized.

Abstract: In an image reading apparatus, a user ID is input as login information pertaining to the user who implemented reading of the original document. The user ID is embedded in the image data created from the original document data as an electronic watermark, and the image data is sent to a PC. The PC that receives the image data reads the user ID from the image data. If the user ID read from the image data matches a user ID entered by a user who issued a printing command, the PC issues a print command regarding the image data. Otherwise, printing is prohibited. Through this processing, printing of the image data is permitted only for the user who implemented reading of the image data.

Abstract: When a print job is received from the network, subsequent processing depends on whether the print job includes authentication information. Where the print job includes authentication information, the print job is stored in a memory while being associated with the authentication information. When authentication information is received from the network thereafter, a print controller selects, from among the print jobs stored in the memory, the job that is associated with authentication information that matches the received authentication information, and causes it to be printed.
