    • This invention can play back a smooth moving image in both normal and slow playback modes in consideration of the human visual recognition level, even when moving image data to be decoded (played back) is recorded (encoded) at a high frame rate. To this end, in this invention, respective frames, which form a moving image at 60 frames/sec, are compressed to be independently decodable. In the normal playback mode, since frames are played back using one of two frames (decimating one of two frames), a moving image is played back at 30 frames/sec which can assure sufficiently high image quality as a moving image. On the other hand, in the slow play back mode, since the number of frames to be decimated is set to be zero, and 60 frames are played back for 2 sec, a moving image is played back at the same frame rate of 30 frames/sec as that in the normal playback mode.
    • 考虑到人类视觉识别水平,本发明可以在正常和慢速播放模式中播放平滑的运动图像,即使当以高帧速率记录(编码)待解码(回放)的运动图像数据时。 为此,在本发明中,以60帧/秒形成运动图像的各个帧被压缩为独立地可解码。 在正常播放模式中,由于使用两帧中的一个(对二帧中的一帧进行抽取)来播放帧,所以以30帧/秒的速度播放运动图像,这可以确保足够高的图像质量作为运动图像。 另一方面,在慢播放模式中,由于要抽取的帧数被设置为零,并且将60帧重放为2秒,所以以30帧的相同帧速率播放运动图像 /秒为正常播放模式。

    • This invention enables to generate encoded data without noticeable image quality degradation when reproducing an image at a lower resolution not to mention the original resolution. An image a digital camera can capture takes three sizes L, M, and S. When the size L is designated, stream conversion information SC is set to “2”. When the size M is designated, the stream conversion information SC is set to “1”. When the size S is designated, the stream conversion information SC is set to “0”. When encoding image data in compression processing, block overlap processing of suppressing discontinuity of data at the boundary between adjacent blocks is executed as many times as the count set in the stream conversion information.

    • This invention enables to generate encoded data without noticeable image quality degradation when reproducing an image at a lower resolution not to mention the original resolution. To accomplish this, when setting is done to transmit an image captured by a digital camera to a network, code stream forming information CF is set to “2” to arrange the encoded data of each tile in a resolution order. To suppress image quality degradation when reproducing at an intermediate resolution, stream conversion information SC is set to “2”.
