摘要： A video transmission system and method is provided, by which if the arrival of a signal sent from the video receiving side to the sending side is delayed, or if an error is generated in a signal for communicating a receiving error, it is possible to prevent a situation such that no effective reference picture exists in a (picture) memory. In the present method, storing of encoded data into a memory section is controlled based on information indicated by a signal received from the video receiving side, and the control includes determination whether new data are stored, determination of an area for storing data in the memory section, and deletion of data stored in the memory section. In order to reduce the memory size, it is desirable to delete (i) reference pictures older than a reference picture used for the newest encoded video data which was correctly received, or (ii) a reference picture used for the encoded video data about which a receiving error is communicated from the video receiving side, among reference pictures stored in the memory section.

摘要： A method for displaying computer generated holograms of a display object is performed by computing fringe patterns produced by light interference from the display object. The steps are summarized as follows: three-dimensional data of the display object are converted into computational data for fringe pattern generation; a sampling rule for sampling computational data is selected; computational data are sampled according to a selected sampling rule; wavefronts generated by light illumination are computed by assuming that each sampled position has a light source; fringe patterns generated by computed wavefronts and a reference beam are computed; fringe patterns are stored as hologram images; sampling and a wavefront generation are repeated for all data; and a series of hologram images thus generated are displayed successively.

摘要： A method and an apparatus for three-dimensional holographic display suitable for moving object display are disclosed. At least one hologram of a display target object is displayed on a display device, and a non-scattered light is irradiated onto the display device to produce a scattered light. Then the scattered light from the display device as an object light of the display target object and the non-scattered light as a reference light are irradiated simultaneously at different incident angles onto a photorefractive medium having a photorefractive effect, and interference fringes generated by the object light and the reference light are recorded in the photorefractive medium. Then, the three-dimensional image is displayed by irradiating only the non-scattered light onto the photorefractive medium so as to reproduce a holographic image corresponding to the interference fringes recorded in the photorefractive medium.

摘要： The present invention provides an image transmission method employing phase/amplitude resolution processing in which three-dimensional data of an object recorded as a holographic fringe pattern by means of reference light and light from the object are transmitted sequentially, and at the receiving side, the holographic fringe patterns received are displayed sequentially and with reference to the reproduced light, and the object is displayed in a three-dimensional manner; wherein, at the transmission side, the following processes are executed: a process in which the image of the holographic fringe pattern expressed in terms of complex numbers is decomposed into an amplitude component image and a phase component image, a process in which the high frequency component of the spatial frequency in the amplitude component image decomposed in this way is reduced, processing for converting the gradation in the phase component image is carried out, and each image is compressed and encoded after this processing, and a process in which the image data of the two components compressed and encoded in this way are separately transmitted; while on the receiving side, the following processes are executed: a process in which the image data of the two components, which were separately transmitted, are received, a process in which the received image data are decoded sequentially into an amplitude component image and a phase component image, and a process in which the decoded amplitude component image and phase component image are again combined into a complex component and displayed.
