In a meeting system, supplied-data which is convertible using a virtual machine is transmitted and received among a plurality of processing apparatuses interconnected via a transmission line, and meeting data is reproduced. At least two of the plurality of processing apparatuses include a meeting data reproducing apparatus respectively. At least one meeting data reproducing apparatus includes converting means including a virtual machine for converting the supplied-data into a data format which allows the meeting data to be reproduced, a communication interface unit for receiving the supplied-data from other processing apparatuses, and storage means in which a generated image is stored and which is accessible by other processing apparatuses via the communication interface unit. Each of at least one meeting data reproducing apparatus described above and another meeting data reproducing apparatus including the converting means and the communication interface unit reads part of the meeting data from the storage means and reproduces meeting data in a task-distributed fashion.

Meeting system and information storage medium

An image display system transmits and receives supplied data which can be converted by a virtual machine among plural processing devices which are connected via a transmission line, and creates and displays an image. At least two processing devices among the plural processing devices each includes an image display device. At least one of the image display devices includes a conversion device, in which a virtual machine is provided, that converts the supplied data into a data format in which an image can be displayed, a communication interface section that receives the supplied data from another processing device, and a storage device in which created images are stored and which can be accessed from another processing device via the communication interface section. Each of the at least one of the image display device and the other image display device reads some of the images from the storage device and display the images in a shared manner, the other image display device having the conversion device and the communication interface section.

A projection display apparatus employing organic EL elements is presented that is light in weight, is small in size, and can be practically implemented. In particular, the apparatus suppresses light-emission performance degradation caused by generated heat, thereby extending useful life, stabilizing brightness, and securing continual maximum brightness. The apparatus comprises: liquid crystal panels R, G, and B; light emitting units R, G, and B, positioned at the back of the liquid crystal panels and provided with organic EL elements as light emitting layers; and cooling bodies R, G, and B, positioned at the back of the light emitting units, for dispersing the heat generated by the light emitting layers. The cooling bodies R, G, and B may, for example, be electronic cooling elements that employ the Peltier effect to absorb and radiate the generated heat. Alternatively, the cooling bodies may be configured as heat-dispersing fins that guide and disperse generated heat.

In a body mount-type information display apparatus, a display unit (,) is attached to the head of a user, whereas a control circuit unit (,) is attached to the waist or the shoulder. The display unit enables a light beam from the outside to enter the eyes of the user as well as another light beam representing an image produced by the control circuit unit. The user can accordingly observe the image including required pieces of information for the work together with the outside view. This image may be menu-type information or an image in harmony with an object such as a building. In order to display the image in harmony with the object, the direction, the visual angle, and the size of the image are processed according to the positional relationship between the user and the object. Available input means include magnetic and optical pointing devices and a CCD camera for reading a bar code. The control circuit unit that is not attached to the body may be connected with peripheral equipment and used as a desktop computer.

A projection-type color display device. The display device includes a light source which provides light and a color separation member which receives the light and which separates the received light into the different colors of red, blue and green light. A light valve device receives the red, blue and green light and modulates the light to produce images. A color synthesis cube prism synthesizes the three monochromatic lights modulated by the light valve. A projection lens system projects the synthesized image onto a screen for viewing.
