摘要:
The Chamaecyparis obtusa extract can be extracted by various methods. For instance, an extraction solvent may be applied to leaves, trunks or branches of the Chamaecyparis obtuse for hot water extraction, cold solvent immersing extraction or warm solvent immersing extraction. In this case, the extraction solvent is added to the Chamaecyparis obtuse 2 to 20 times in a weight ratio to then be mixed, followed by extracting at 10 to 150 for 1 to 24 hours. Here, at least one selected from the group consisting of water, C1-C4 lower alcohols, polyalcohols or mixtures thereof may be used as the extraction solvent. The C1-C4 lower alcohols may include methanol, ethanol, and so on. The polyalcohols may include butylene glycol, propylene glycol, pentylene glycol. The mixtures may include a mixture of water and a lower alcohol, a mixture of water and a polyalcohol, a mixture of water and a lower alcohol and a polyalcohol, or a mixture of water, a lower alcohol and a polyalcohol.

An image processing method which determines and depth-unfolds a depth folding region in an input depth image. A depth folding region of an input depth image may be determined based on a variance of the input depth, image or a gradient image. A predetermined first depth value may be added to a depth value of each pixel of the determined depth folding region and depth information of the input depth image may be updated.

An inspection method for a circuit substrate is disclosed, which inspects electrical properties of a circuit substrate having a multilayered structure, by controlling inspection environments so that dew forms on a surface of the circuit substrate and detecting change of states of the dew to thereby determining variation of a thermal capacity of a conductor with respect to defective contacts or vias, micro vias and a circuit pattern of an inner layer. According to this, the inspection can be performed with respect to a wide area simultaneously and therefore the inspection productivity can be improved. In addition, since the temperature of the conductive wire can be measured directly through change of the dew, the cost for the temperature measurement can be saved. Moreover, the cost for an area sensor to sense the temperature of a wide area may be reduced while improving the inspection speed.
