摘要： In a digital camera 1, in an automatic shooting stand-by state, when judged at Step S26 that an automatic shooting condition has been satisfied (N at Step S26), whether or not to issue an AE re-processing command is judged. In other words, whether or not the current shooting condition is similar to a condition where an automatic shooting condition is satisfied is judged. When judged to issue the AE re-processing command, exposure tracking in an aperture-priority mode is performed (S28), and shooting exposure conditions excluding the aperture value for still-image shooting in the aperture-priority mode are determined. Then, the storage is updated (Step 29), and the process returns to Step S26. When judged at Step S26 that an automatic shooting condition has been satisfied (Y at Step S26), record processing for still-image shooting is performed with the updated shooting exposure conditions without changing the aperture value (Step S30).

摘要： In a photographing apparatus, while a deterioration of a contrast characteristic caused by an optical zooming operation is prevented, superior photographic images are continuously acquired. Magnification set by an optical zooming function is acquired, and a gamma curve, namely gradation correcting information is set to a gamma lookup table, while the gamma curve is applied during a photographing operation based upon the acquired set magnification. A gamma correcting unit corrects gradation of image data (namely, RAW data) outputted from an imaging element by employing gradation correcting information set in this gamma lookup table.
