  • Patent number: 11307332
    Abstract: Provided is a diffusion sheet having a function for preventing warping, and having excellent optical and diffusion characteristics. A diffusion sheet 1 has a minute roughness pattern formed on the surface thereof, the pattern configured such that first protrusions 3a having a first height and second protrusions 3b having a second height lower than the first height are disposed in parallel. A portion of the first protrusions 3a is bonded to a bonding layer on the rear surface of an upper-layer sheet laminated on the surface of a diffusion sheet 2, and the second protrusions 3b are not bonded to said bonding layer. The following relationships are satisfied: h1:h2=1:0.5-0.1, and w1:w2=1:1.0-0.1, where h1 is the height of the first protrusions 3a, w1 is the width of the first protrusions 3a, h2 is the height of the second protrusions 3b, and w2 is the width of the second protrusions 3b.

  • Patent number: 10148966
    Abstract: To allow a finer quantization control according to the property of an image within a macroblock, quantization parameter values are allowed to be changed in units of sub-blocks equal to or smaller than the macroblock in a similar manner as in motion compensation and orthogonal transform processes. A finer-tuned quantization control is performed, for example, by selecting fine and coarse quantization parameters respectively for corresponding sub-blocks if a plurality of images having different properties coexist within the macroblock.
