摘要： A method and apparatus is disclosed which can reproduce multi-value data with high reproducibility from a hologram recording medium having data recorded in multi-values therein and can reduce the error rate of reproduction data. A reference gradation pattern is recorded in a medium, and luminance unevenness of a gradation pattern obtained by reproducing the gradation pattern is corrected. A gamma characteristic of the medium is determined based on the reproduction gradation pattern, and a modulation pattern produced using easily separable luminance values determined based on the gamma characteristic is displayed on a spatial light modulator to record data in multi-values into the medium. Thereupon, the data are oversampled and recorded, and a block of the reproduced data is decoded depending upon a sequence of relative luminance levels of pixels in the block to decode the entire reproduced multi-value data.

摘要： The present invention provides a hologram apparatus for recording interference fringes formed from reference light and signal light optically spatially modulated by a spatial light modulator on a hologram recording material or picking up an image of reproduction signal light produced by irradiating illumination reproduction light on the hologram recording material by means of an image pickup device to obtain a reproduction image signal. The hologram apparatus includes a matching data acquisition section, an arithmetic operation section, and a positioning control section. The matching data acquisition section directly picks up an image of the signal light optically spatially modulated with a pixel matching pattern displayed on the spatial light modulator by means of the image pickup device to obtain a reproduction image signal. The arithmetic operation section performs predetermined arithmetic operation using a luminance value of the reproduction image signal. The positioning control section moves a relative position between the image pickup device and the spatial light modulator in response to a result of the arithmetic operation of the arithmetic operation section.

摘要： An apparatus and a method which enable effective removal of flicker are provided. Under an illumination environment such as a fluorescent lamp with luminance variation, flicker that occurs in images shot with an X-Y address scanning type imaging device such as a CMOS is effectively removed or reduced. The integral value of the row-by-row signal intensity of an image to be corrected from which to remove flicker is calculated, and this integral value is used to detect flicker components contained in individual rows of an image frame. The detected flicker components represent data according to the actual flicker waveform of the illumination, and a correction process is executed using flicker correction coefficients formed by an anti-phase pattern of the flicker components. Effective flicker removal becomes possible through this process.
