IMAGE GENERATOR, IMAGE PICKUP DEVICE, MOVING IMAGE GENERATOR, IMAGE GENERATION METHOD, IMAGE GENERATION PROGRAM AND RECORDING MEDIUM WITH IMAGE GENERATION PROGRAM RECORDED THEREON
PROBLEM TO BE SOLVED: To provide an image generator, an image pickup device, a moving image generator, an image generation method, an image generation program or a recording medium having the program recorded thereon, with which the images of a higher number of gradations and high image quality can be obtained from photographed moving images.;SOLUTION: A composition means 33 performs a composition processing to four frame images F0-F3 gradation-expressed 8 bits. An obtained generated frame image Fm has the data of 2 bits indicating a fractional part generated by the computation of the composition processing in addition to the data of 8 bits indicating an integer part. A gradation conversion means 34 acquires the generated frame image Fm for which the integer part is gradation-expressed by 10 bits by using the data of the integer part and the data of the fractional part of the generated frame image Fm.;COPYRIGHT: (C)2006,JPO&NCIPI
