Abstract: A camera system controls a camera via a network. The system comprises a client having transmission means for transmitting to a camera control apparatus, a character string described in a format of file-transfer request used on the network, wherein the character string is included in a URL, and obtaining means for obtaining video image data transferred from the camera control apparatus, wherein the camera control apparatus has reception means for receiving the character string from the client via the network discrimination means for discriminating a predetermined control character relating to a type of camera control and a control character related to a control amount at a particular position of the URL, and control means for controlling the camera based on the result of discrimination by said discrimination means and transferring video image data obtained by the camera to the client as a file-transfer request originator.

Abstract: The object of the present invention is to provide a method and an apparatus for document processing whereby it can be easily determined whether or not document data has been changed since a user last referred to it. A document data group, which holds a plurality of document data, and update time data for each user of the document data, which is held in the document data group, are held in user-by-user document reference time data. When the document data that is held in the document data group is read after a user is specified, the update time data for the read-out document data is read from the user-by-user document reference time data. Then, a check is performed to determine whether or not a person who performed the latest document data update is the specified user or is another user. In consonance with the result, the document data that has been updated by a user other than the specified user is so displayed on a display section that it can easily be identified.

Abstract: It is aimed to determine whether or not the rewrite of a stored data has been made by a person other than the regular creator. Therefore, in storing the data, a first code is generated by converting the password and a predetermined portion of the stored data (e.g., data itself or time stamp) in a predetermined procedure, and stored in correspondence to the stored data. Thereafter, in reading the stored data, a second code is generated by converting the password and the predetermined portion of the stored data in the predetermined procedure, and the comparison is made between the generated second code and the first code stored in correspondence to the stored data to determine that the rewrite has been made if unmatched.

Abstract: An image forming apparatus comprising an exposure light source, a printer head which comprises a group of micro-shutters each controlling the transmission or interruption of light from the exposure light source, and an image bearing so disposed to be irradiated with light signals transmitted through the printer head. The group of micro-shutters are arranged in a matrix comprising a plurality of rows and a plurality of columns. The group of micro-shutters are formed by a substrate having thereon a plurality of segment electrodes each forming a shutter and connected to a drain of a thin film transistor, another substrate having thereon a common electrode, and a liquid crystal interposed between the substrates. The image forming apparatus further comprises means for applying a scanning signal to the gate of the thin film transistor and applying an electric signal corresponding to image information in synchronism with the scanning signal.

Abstract: An image formation apparatus has a photosensitive drum or photosensitive paper sheet for forming a dot image thereon, a printer head having an LED array, and LED drive ICs for selectively driving the LEDs. Dot width in the subscanning direction is properly controlled to form an excellent pseudo halftone image. A cylindrical lens or the like can be inserted between the LED array and the drum so as to prevent formation of black or white stripes in white or black image portions.

Abstract: A dot printer has an LED array printer head consisting an array of LEDs, drivers for independently driving the LEDs, and time control circuits for controlling ON or OFF times of the LEDs by energizing the drivers in accordance with image data and correction data stored in a memory. The LEDs can be divided into blocks which can be sequentially driven. Variations in mechanical and electrical characteristics of the LEDs are corrected to allow formation of a high-resolution image or a halftone image.

Abstract: A comment added to a certain portion in a first document can be automatically re-added to an equivalent position in a second document, and comment transfer processing between documents is automatically performed. Position information of a comment with respect to an old document obtained from an old document comment file is stored in a position information area, and comment contents also obtained from the old document comment file are stored in a comment content area. A character string corresponding to the position information is extracted from an old document file, and is stored in a character string area. A new document file is searched on the basis of the character string stored in the character string area, and position information of the detected character string is stored in a candidate area. One of position information stored in the candidate area is selected according to a predetermined rule, and the selected position information is stored in a new position information area. The comment contents stored in the comment content area, and the position information stored in the new position information area are written in a new document comment file.
