Photovoltaic device

A photovoltaic device includes a liquid-repelling layer between the edges of a first amorphous semiconductor layer and the edges of a second amorphous semiconductor layer. No such a liquid-repelling layer is provided between the first amorphous semiconductor layer and the second amorphous semiconductor layer, except between the edges of the first amorphous semiconductor layer and the edges of the second amorphous semiconductor layer. The semiconductor layer in the photovoltaic device is therefore precisely patterned.

It is an object to prevent the image quality deterioration of a moving image likely to include a plurality of the same consecutive images such as a movie video and an animation video due to the motion-compensated frame rate conversion (FRC) processing. An image displaying device is provided with an FRC portion () for converting the number of frames in an input image signal by interpolating an image signal to which a motion compensation processing has been given between the frames in the input image signal, a genre determining portion () for determining whether the input image signal is a predetermined genre, and a controlling portion (). The FRC portion () includes a motion vector detecting portion () for detecting a motion vector between the frames of the input image signal, an interpolating vector evaluating portion () for allocating an interpolating vector between the frames based on the motion vector information, and an interpolating frame generating portion () for generating an interpolating frame from the interpolating vector. In the case that the input image signal is relating to a movie or animation, the control portion () set the motion vector detected by the motion vector detecting portion () to zero-vector to make the motion compensation processing of the FRC portion () ineffective.

Deterioration of the image quality of a moving image which is deteriorated due to a motion-compensated frame rate conversion (FRC) processing is prevented. An image display device comprises an FRC portion () for converting the number of frames of an input image signal by interpolating an image signal to which the motion compensation processing is performed between frames of the input image signal and a controlling portion () for controlling the operation of the FRC portion () after determining whether or not the degree of deterioration of the input image signal is equal to or higher than a predetermined value. The FRC portion () comprises a motion vector detecting portion () for detecting a motion vector between frames of the input image signal, an interpolating vector evaluating portion () for allocating an interpolating vector between the frames based on the motion vector information, and an interpolating frame generating portion () for generating an interpolating frame from the interpolating vector. If the degree of deterioration of the input image signal is equal to or higher than a predetermined value, the controlling portion () makes the motion compensation of the FRC portion () ineffective by setting the motion vector detected by the motion vector detecting portion () to a zero vector.
