摘要:
A blur correction camera system includes a blur correction lens driven based upon the vibration detection signal detected by an angular velocity sensor, that corrects an image blur, a point-image function computing unit that computes a point spread function, and an image restoration computing unit that corrects an image blur by executing image restoration through image processing on a captured image by using the point spread function. The image blur that cannot be completely corrected by the blur correction lens is further corrected through image restoration so as to obtain a high quality image.

The present invention provides heat-expanded microspheres having high packing efficiency, and a production method thereof. The heat-expanded microspheres are produced by expanding heat-expandable microspheres, which comprise shell of thermoplastic resin and a blowing agent encapsulated therein having a boiling point not higher than the softening point of the thermoplastic resin and have an average particle size from 1 to 100 micrometer, at a temperature not lower than their expansion initiating temperature, and the heat-expanded microspheres result in a void fraction not higher than 0.70.

Provided is a pneumatic tire whose frictional force on ice is improved by satisfactorily forming resin-encapsulated cells from heat-expandable microcapsules, even when a tread rubber contains silica. The tire is characterized in that: the tread rubber is made of a rubber composition containing 100 parts by weight of a diene rubber, 30 to 100 parts by weight of a reinforcing filler including at least 10 parts by weight of silica, and 1 to 20 parts by weight of microcapsules each encapsulating a heat-expandable substance; a sulfur-containing silane coupling agent is mixed in the rubber composition in an amount of 3 to 15 wt. % based on the weight of the silica; a shell material of each microcapsule is made of a thermoplastic resin which essentially contains a nitrile monomer (I); a vapor pressure of the heat-expandable substance is set at 1.4 to 3.0 MPa at 150° C.; an average particle diameter of the microcapsules is set at 20 to 30 μm before vulcanization of the rubber composition; an average particle diameter of the microcapsules expanded due to the vulcanization is set at 40 to 80 μm; and thus, a proportion of an area occupied by the cells in the tread rubber is set at 5 to 30%.
