    摘要: The present invention relates to a data processing apparatus for a camera in which correction data for shading correction or the like is stored in a memory and an output formed by a photo-taking information forming circuit such as a sensor and the correction data are operated to thereby accomplish the photo-taking processing on the basis of the operational output. When the data stored in the memory is read out and the operation processing is effected, if an error is contained in the read-out data, the data is subjected to revision processing to thereby correct the error, and then the operation processing is accomplished.

The receiving unit receives one of a first command and a second command. The first command includes information indicating one of a plurality of secret keys, and the plurality of secret keys are included in the digital signature generating apparatus. The secret key changing unit changes a secret key used by the digital signature generating apparatus to a secret key specified by the first command, if the first command is received by the receiving unit. The digital signature generating unit generates the digital signature of the digital data from a hash value extracted from the second command, if the second command is received by the receiving unit.
