First Claim
Patent Images
1. An electronic camera, comprising:
- an image sensor;
a rangefinding means;
an arithmetic operation means for calculating a characteristic quantities based upon at least either pixel density in an image obtained via the image sensor or rangefinding information obtained via the rangefinding means;
a judgment means for judging a photographic scene based upon characteristic quantities calculated by the arithmetic operation means; and
a control means for selecting camera settings in correspondence to the photographic scene having been judged.

20. An electronic camera, comprising:
-
an image sensor; a rangefinding means; an arithmetic operation means for individually calculating characteristic quantities based upon at least two of;
pixel density in an image obtained via the image sensor, an extent of change in pixel density corresponding to a main subject, rangefinding information for a main subject obtained via the rangefinding means, rangefinding information for a background obtained via the rangefinding means, and an extent of change in a rangefinding information for the main subject;a judging means for judging a photographic scene in correspondence to characteristic quantities calculated by the arithmetic operation means; and a control means for arranging camera settings in correspondence to the photographic scene having been judged.
