摘要:
A video distribution system which is enhanced in flexibility in distribution mode switching. In a camera server connected to a viewer via a network, a video capture board captures a video image. A CPU processes the captured video image according to an electronic PTZ mode for cutting out a part of the captured video image and a mechanical PTZ emulation mode for cutting out parts of the captured video image and interpolating the cut-out images. The CPU distributes the processed video image to the viewer via the network. The CPU performs mode switching between the electronic PTZ mode and the mechanical PTZ emulation mode based on control information transmitted from the viewer.

An image distribution system, which is connected via a network with a client for displaying an image picked up by an image sensing unit of a server, judges a communication status of the network. In addition, in accordance with a result of the judgment, the image distribution system changes a user interface for selecting a function request command for the image sensing unit of the imaging apparatus.

When a user process issues an input/output request in a process performed in response to the input/output request generated by the user process, the input/output request is queued in the input/output request list which is a queue in a list format on the user space side. On the kernel side, when a input/output request in the input/output request list is processed, the status is changed into ‘processed’, and a list element whose status indicates ‘processed’ is removed from the request list on the user space side. On the kernel side, a thread for performing a process in response to an input/output request is divided into a plurality of threads, and the CPU is released to another thread before completion of the process.

A method of discriminating, for each first level partial data, whether or not saved data, one file of which is composed of a plurality of the first level partial data and each of the first level partial data is able to include a second level partial data, has been unjustifiably rewritten. The method includes the steps of at a time of saving a file, designating a first level partial data on the basis of a user instruction, receiving a password from a user, converting the received password and the designated first level partial data, which includes second level partial data, according to a predetermined procedure to generate a first code and saving the file with storing of the first code to correspond to the designated first level partial data. At a time of reading the saved file, reading the saved file, designating the first level partial data on the basis of a user instruction, receiving the password from the user, converting the received password and the designated first level partial data, which includes the second level partial data if the designated first level partial data includes the second level partial data, according to the predetermined procedure to generate a second code. The method compares the generated second code with the first code stored to correspond to the designated first level partial data, and discriminates that the designated first level partial data has been unjustifiably rewritten if comparison results in a fact that the first code is not equal to the second code.
摘要:
A piezoelectric ignition device for spark-igniting a fuel of such burning instruments as cigaret lighters, gas ranges and the like, utilizing a high electric voltage obtained by giving a bending stress in lengthwise direction to an elongated rectangular plate-shaped porcelain piezoelectric element. A plurality of electrodes is formed at least on one of the surfaces of the plate-shaped element along the respective lines parallel to lengthwise both ends and dividing the element lengthwise into "n" divisions, and adjacent divisions are polarized reversely to each other also in the lengthwise direction. A force-to-electricity conversion is made with a piezoelectric constant g.sub.33.

A technique of directly and simply operating image data stored in an external storage device using a camera is provided. To accomplish this, an image processing device connectable to a network, comprises a connection unit configured to connect to an imaging device, an acquisition unit configured to acquire image data captured by the imaging device from an external device on the network, in accordance with a user operation on the imaging device, and a display control unit configured to display the image data acquired by the acquisition unit and image data stored in the imaging device in accordance with a display unit of the imaging device.
摘要:
A control apparatus for controlling a projector apparatus projecting an image in provided. The apparatus includes an input unit for inputting layout information relating to a layout of the images projected by a plurality of projector apparatuses, an obtaining unit for obtaining respective projection areas of the plurality of projector apparatuses, a determination unit for determining a correction amount of the respective projection areas of the plurality of projector apparatuses based on the layout information input by the input unit and the projection areas obtained by the obtaining unit, and a notifying unit for notifying the plurality of projector apparatuses of the correction amount determined by the determination unit.

In a compact information terminal apparatus including display means having a displaying function equivalent to that of a personal computer, a browser for browsing a hyper text can easily be manipulated without altering the hyper text formed for the personal computer. When a position other than a hot spot of the hyper text on a browsing view is designated by using a position designating input device which can be manipulated by one hand, a group of operation buttons of the browser for the hyper text is displayed in the vicinity of a designated position.
