    摘要： Pictures are captured, and thereby moving-picture data is generated which represents a sequence of moving-picture fields. At least one picture is captured, and thereby still-picture data is generated which represents at least one still-picture frame corresponding in picture capture timing to one of the moving-picture fields represented by the moving-picture data. Components which correspond to said one of the moving-picture fields are removed from the still-picture data to generate supplementary still-picture information. Link information is generated which represents the picture capture timing correspondence between the still-picture frame and said one of the moving-picture fields. The moving-picture data, the supplementary still-picture information, and the link information are recorded on a recording medium.

    摘要： Bits of a first bit sequence are rearranged in a first matrix according to a predetermined arrangement rule. The first bit sequence represents information being a base of a key. Blocks are formed in the first matrix. Each of the blocks has bits, the number of which is smaller than the number of bits composing the first matrix. Logical operation is executed among bits in each of the blocks, and a bit being a result of the logical operation is generated. The logical-operation-result bits are combined into a second bit sequence. The number of bits composing the second bit sequence is smaller than the number of bits composing the first bit sequence. There is a second matrix composed of predetermined third bit sequences. The second matrix is accessed and one is read out from among the third bit sequences in response to the second bit sequence. The read-out third bit sequence is outputted as information representative of the key. The number of bits composing each of the third bit sequences is smaller than the number of bits composing the second bit sequence.
