    摘要: Sialic acid derivatives represented by the general formula (I): ##STR1## wherein R.sup.1 is a steroidal compound residue; R.sup.2 is H or alkyl; R.sup.3 is alkyl; ##STR2## wherein each of R.sup.6 and R.sup.7 is H, alkyl or the like and I is an integer of 0 to 6; or the like; X is O or S; R.sup.4 is H or acyl; and R.sup.5 is R.sup.14 O-- (R.sup.14 is H or acyl) or R.sup.15 NH--(R.sup.15 is acyl or the like); their salts, hydrates or solvates are provided. Sialic acid derivatives of the present invention are expected to be effective medicines for the prevention and therapy of senile dementia including Alzheimer's disease and the like, because they increase ChAT activity in cholinergic neurons.

    摘要: A color filter arrangement (11) is used, in which a plurality of filter units are each made of 2×2 arrangements of red (R), green (G), green (G) and blue (B) color elements. First, signal charges are added up for all pixels belonging to each of a plurality of pixel blocks made of quadratic arrangements of 3×3 of pixels, which are larger than the filter units (2×2 arrangement). Then, compressed color information for each of the pixel blocks is obtained from a result of the addition for each pixel block, taking the 2×2 arrangements of pixel blocks as large filter units.
