摘要： A transmissive display device includes: a light source which outputs light; a display part which receives the light from the light source and generates display light representing an image; a deflecting element which changes a direction of the display light emitted from the display part; and a transmissive reflector which reflects, towards a user, light of a wavelength included in the display light emitted from the display part, and transmits light of other wavelengths. An angle formed by a straight line, which extends between an upper edge of an incident area of the display light on the transmissive reflector and a lower portion of an eyebox which is defined as a visible range of the reflected light from the transmissive reflector, with respect to a horizontal line is smaller than a difference between an emission angle and an incident angle of the display light at the transmissive reflector.

摘要： An object of the invention is to prevent lowering of a dynamic range of a hologram recording medium without lowering an average data transfer rate, and to provide stabilized recording sensitivity. A scheduler determines a recording interval time from the point of time when light is irradiated to record a certain hologram of holograms to be multiplex-recorded to the point of time when light is irradiated to record a succeeding hologram in such a manner that at least parts of the holograms are recorded one over the other in a certain recording area. A recording interval time controller controls a light source to irradiate the light depending on the recording interval time determined by the scheduler.

摘要： A two-dimensional encoder stores data on a holographic memory. The encoder encodes data of k bits (where k is an integer and k≧3) into n pixels arranged two-dimensionally (where n is an integer and n≧6). The encoder includes a first processing section 31 for classifying the n pixels into first and second groups of subblocks 11 and 12 using k1 bits out of the data of k bits (where k1 is an integer and k1≧1). Each of the subblocks 11 in the first group consists of m pixels (where m is an integer and m≧2), and the number of the subblocks 11 forming the first group is s1 (where s1 is an integer and s1≧2). Each of the subblocks 12 in the second group also consists of m pixels, and the number of the subblocks 12 forming the second group is s2 (where s2 is an integer and s2≧1). The encoder further includes a second processing section 32 for turning ON p pixels (where p is an integer and 1≦p≦m/2) out of the m pixels forming each subblock 11 in the first group and turning OFF all of the m pixels forming each subblock 12 in the second group using the other k2 bits of the data of k bits (where k2=k−k1).
