Abstract: To effectively reduce the load on a device involved in converting the format of content data. A storage unit (14) stores format information that includes at least information about the container format of first content data and encoding information about multimedia data included in the first content data; and a container converter (16) converts the second container format of second content data into the first container format of the first content data on the basis of information stored in the storage unit (14), without decoding the multimedia data included in the second content data and without encoding the multimedia data obtained as a result of the decoding, whereby the first content data is generated.

Abstract: Conventionally, when generating an image in which hand-shake is suppressed, by combining a plurality of images, an image quality may be degraded by performing a combination process even in the illuminance condition when no hand-shake occurs and the linear characteristic of luminance information may be deteriorated when combining a plurality of images, some which are inappropriately exposed. In order to solve these problems, it is possible to provide an imaging device capable of combining a first image of a size smaller than a target image obtained by pixel addition average and pixel addition with a second image having an amplified gain to obtain an appropriate exposure and a plenty of noise, so as to generate the target image and capable of varying the synthesis ratio of the first image and the second image according to the temperature condition and the like so as to obtain an image in which no hand-shake or blur is contained under any illuminance condition and noise is suppressed.

Abstract: A photographing lens position control device comprises an image signal capturing unit for capturing an image signal, a focus lens moving unit for moving a focus lens while the image signal capturing unit is capturing an image signal, a retaining unit for retaining a position-dependent image signal, and a photographing lens position determining unit for determining a photographing lens position based on a position-dependent image signal. Since a focus lens is moved while an image signal is being captured as mentioned above, time required for capturing an image signal for determining a photographing lens position is shorter than before.
