  • Publication number: 20160085980
    Abstract: The present invention avoids execution of processing not intended by the user on the photographed image in a locked state. The image photographed by a camera which is in a lock released state is stored in a user area created in a storage area. On the other hand, an image photographed by a camera, which turned to a locked state as a result of being performed no operation for more than a fixed time, is stored in an area where stores the photographed image photographed in a locked state (second storage area). The image stored in the second storage area is determined after an input of a user's instruction with regard to the processing to be performed on the image.

  • Patent number: 9059103
    Abstract: Disclosed is a processing method that removes moisture in a low permittivity film formed on a substrate to be processed which has a damaged layer on the surface thereof while maintaining the specific permittivity or a leakage current value low when the film is subjected to a recovery processing. The method for the recovery processing includes applying, on the damaged layer of the low permittivity film, a first processing gas whose molecules are small sufficient to permeate the inside of the damaged layer of the low permittivity film and which is able to remove the moisture in the damaged layer and a second processing gas which forms a hydrophobic dense reformatted layer on the surface of the damaged layer, thereby allowing the first processing gas and the second processing gas to react with the damaged layer.
