Abstract:
1. An electronic camera, comprising: an imager for carrying out an exposing operation for exposing an object scene and an amplifying operation for amplifying an image signal generated by said exposing operation, according to a set imaging parameter; a holder for holding a plurality of program charts each of which is represented by M imaging parameters wherein M is an integer equal to or larger than three; a detector for detecting an EV value corresponding to a calculated exposure time; a selector for selecting a single program chart which satisfies a parameter condition, from among the plurality of program charts held by said holder; an extractor for extracting N imaging parameters from the program chart selected by said selector, wherein N is an integer equal to or larger than two and smaller than M; and a setter for setting the N imaging parameters extracted by said extractor to said imager, wherein each of the imaging parameters includes an exposure time, an amount of aperture and an amplification factor as parameter elements, wherein the imager implements bracket photography including executing AE shift continuous shooting N times, wherein the parameter condition includes an amplification factor condition in that each of N amplification factors defining respectively the N imaging parameters is equal to or less than a predetermined value and an exposure time condition in that N exposure times defining respectively the N imaging parameters are shorter, and wherein the selector selects the single program chart based on the exposure time condition such that the N exposure times of the N imaging parameters corresponding to the detected EV value become shorter.
