Abstract
The present invention provides a user-friendly camera having a silver-salt picture-taking function and an electronic-image pickup function. The camera includes a silver-salt picture-taking unit and an electronic-image pickup unit. The electronic-image pickup unit picks up an electronic image, which is almost equivalent to a subject image exposed to a silver-salt film, in synchronization with the exposure to the silver-salt film in the silver-salt picture-taking unit. Prior to the exposure, a control circuit causes a battery check circuit to check a power supply battery and causes a determination circuit to determine a result of the battery check while referring to a determination-level storage circuit, thereby properly controlling the silver-salt picture-taking unit and the electronic-image pickup unit so as to prevent the electronic-image pickup unit from performing its pickup operation in the subsequent picture-taking operations.
