A removable recording medium having an area for storing a content and, when attached to a reproducing apparatus, allowing the content recorded in the area to be reproduced is arranged so as to include, separately from the area for storing the content, an area for storing one or more conditions that allow the content to be reproduced by the reproducing apparatus. With this arrangement, by pre-recording on the recording medium, information for allowing the reproducing apparatus to reproduce a content, the recording apparatus can automatically perform processing such as encoding to a content in accordance with the information recorded on the recording medium and then record the content on the recording medium; and the reproducing apparatus can unconditionally reproduce a content recorded on the recording medium.

Disclosed herein is a 3-D image display unit that can be controlled flexibly to protect the user from eyestrain and operated easily. The 3-D image display unit includes measuring means for measuring a display time of a 3-D image, parallax adjusting means for instructing 3-D image forming means to adjust the parallax of the 3-D image. In the case where the 3-D image display time measured by the measuring means exceeds a predetermined time, the parallax adjusting means instructs the 3-D image forming means to reduce the parallax of the 3-D image to be formed, thereby the display means comes to display a 3-D image having a small parallax. The user can thus be protected from eyestrain.

An image data recording apparatus includes a three-dimensional display control information generation unit receiving a parameter indicating a condition for picking up a three-dimensional image, and encoding the parameter so as to generate image pick-up condition information, and a file generation unit generating a multimedia information file including both of the image pick-up condition information and three-dimensional image data or at least one of the three-dimensional image data and two-dimensional image data.

A moving image/audio recording apparatus in which failure of recording due to erroneous operation and operation timing deviation can be prevented is implemented. Moving image data and audio data prior to the start of recording are multiplexed by a multiplexing unit 103. The multiplexed data is temporarily stored in a built-in memory 104. A control unit 106 which has received an instruction to start a going back recording changes the going back recording start time to the time subsequent to the time when the encoding conditions or channels are changed to those at the time of the instruction to start recording if the encoding condition or the channel at the time which goes back by a period of time preset as the going back time is different from that at the time of the instruction to start recording and consecutively reads out the multiplexed data from the memory 104 for recording them in a recording unit 105 via a changeover switch 108. If the first frame at the time to start the going back recording on the recording unit 105 is not a key frame, recording is started with a key frame which is closest to the time to start the going back recording.

To a multimedia information file including three-dimensional image data, three-dimensional display control information is added that indicates an intended three-dimensional display method for the three-dimensional image data or a data format in which the data is recorded. A three-dimensional image reproduction apparatus performs conversion appropriate for data characteristics derived from the three-dimensional display control information and then provides display. Recorded three-dimensional image data is thus given versatility so that the same three-dimensional image data can be used commonly to different three-dimensional display schemes.

An image encoder/decoder by which a partial image is encoded easily with a resolution meeting the user's demand, wherein the encoded amount of data is not increased and a necessary capacity of memory can be reduced. The image encoder has a tile decomposition portion which divides image data into tiles of N pixels×M pixels, a wavelet transform coding portion which extrapolates predetermined data at the peripheries of the tiles outputted from the tile decomposition portion and performs subdivision to perform wavelet encoding. A management information generating portion generates information for managing the encoded data in order that the encoded data outputted from the wavelet transform coding portion can be decoded for each tile and for each subband of the wavelet encoding. Also, a coded data integration portion links the encoded data encoded by wavelet encoding for each tile by using the output of the management information generating portion and adds the managing information to the encoded data.

An image coding apparatus inputs pixel data of a part image of high resolution. An upper layer coding portion (101), a second shape data generating portion (102), and a second shape data coding portion (103) perform coding of shape data and pixel data in the upper layer. A down sampling portion (104) generates pixel data of low resolution. A lower layer coding portion (105), a first shape data generating portion (106), and a first shape data coding portion (107) code shape data and pixel data in the lower layer.
