Abstract

To provide a scheme that, when making a prediction in multilayer coding, takes into account the quality of the image in each layer and can adaptively determine in want manner to refer to the image of which layer. Provided is an image processing device provided with a prediction control unit that, on the basis of an indicator dependent on the image quality of a first layer image and a second layer image, sets the weighting when including a first layer pixel and a second layer pixel for predicting a pixel in the second layer that is encoded or decoded referring to the first layer.

Claims

1. A sealing device used as a hub bearing seal for a vehicle such as a motor vehicle, or a bearing seal for a construction equipment, the sealing device comprising:

a seal lip which seals so as to prevent a foreign material in a machine external side from entering into a machine internal side; and

a dust lip which makes said foreign material hard to reach said seal lip,

wherein said seal lip is formed by a conductive rubber material, and said dust lip is formed by a material which is lower in a conductivity than said seal lip.

2. The sealing device according to claim 1, wherein said seal lip is made of a material which is obtained by blending a conductive carbon at 3 to 50 weight part in a rubber at 100 weight part, and said dust lip is made of a material which is obtained by blending the conductive carbon at 1 weight part or less in the rubber at 100 weight part.

3. The sealing device according to claim 2, wherein said conductive carbon is constructed by Ketjen black or acetylene black.
