The purpose of the present invention is to achieve highly accurate detection of obstacles even in adverse weather environments, particularly environments in which a scatter phenomenon caused by fog or the like occurs. A target signal processing unitcalculates a cross-correlation function between split reference light from a light source unit, and reflected light from a target T, said reflected light being obtained using split signal light from the light source unit. An estimation unitestimates scattering characteristics of propagation paths of the signal light and the reflected light. A correction processing unitexecutes, on the basis of the scattering characteristics estimated by the estimation unit, prescribed correction processing of the cross-correlation function calculated by the target signal processing unit

Image processing device, method, and program

To provide a hair cleansing composition having good foamability and high-lubricity foam quality upon washing and smooth touch upon rinsing, and providing excellent feeling in use.

Hair cleansing compositions

A hair cleansing composition comprises the following ingredients (A) to (D): The hair cleansing composition has good foamability and high-lubricity foam quality upon washing and smooth touch upon rinsing, and is excellent in the luster and softness of hair after drying and also superb in stability.

A 21-substituted steroid compound is disclosed. The compound has a structure of formula (I), ##STR1## wherein R.sup.1 is a hydrogen atom, a lower alkyl, lower alkenyl, lower alkoxy, or phenyl group, R.sup.2 is a hydroxyl group or an acyloxy group having 1-6 carbon atoms, R.sup.3 is a hydrogen atom or a lower alkyl group, or R.sup.2 and R.sup.3 may together form a lower alkylidenedioxy group, X.sup.1 and X.sup.2 may be the same or different and individually represents a hydrogen atom or a halogen atom, Y.sup.1 and Y.sup.2 may be the same or different and individually represents a methylene group or a sulfur atom, Z is a sulfur atom or an imino group, the wave line means that the configuration of R.sup.3 may be of either .alpha. or .beta., and dotted line between the 1 and 2 position means that the bond may be the double bond. It has excellent anti-inflammatory, anti-allergic and anti-asthma activities with little side effects, and is useful for the prevention, cure, and treatment of on inflammation, allergic diseases, rheumatism, and the like.
