Abstract
A data processing device for a camera wherein a parity bit is provided in data of an EEPROM, and when a parity error is caused by destruction of data or the like, data previously prepared in a ROM is employed, or when data before and after a specific abnormal data are normal, an interpolation calculation is performed by using these normal data. When data memorized in the EEPROM are destructed by an unexpected accident such as by static electricity, the data are prevented from using and picture taking can be continued without applying a serious influence on the picture-taking operation by performing an approximation calculation by using the other normal data memorized in the ROM.
