First Claim
Patent Images
1. A camera comprising:
- (a) a light measuring circuit which measures a light measuring value for exposure control;
(b) a light receiving circuit different from the light measuring circuit;
(c) a first processing circuit for processing an output of said light receiving circuit for implementing a predetermined function of said camera; and
(d) a second processing circuit for determining a kind of light source of light received by said light receiving circuit on the basis of the output of said light receiving circuit.

9. A camera having a remote control circuit which receives a light signal for remote control, comprising:
-
(a) a light receiving circuit for receiving the light signal; (b) switching means for switching a light receiving characteristic of said light receiving circuit between a first characteristic which allows said light receiving circuit to pass a frequency contained in a first frequency band and a second characteristic which allows said light receiving circuit to pass a frequency contained in a second frequency band; (c) a remote control processing circuit for performing a remote control function according to an output which is provided by said light receiving circuit when the light receiving characteristic of said light receiving circuit is switched to the first characteristic; and (d) a decision circuit for determining the kind of light source on the basis of the output which is provided by said light receiving circuit when the light receiving characteristic of said light receiving circuit is switched to the first characteristic and an output which is provided by said light receiving circuit when the light receiving characteristic of said light receiving circuit is switched to the second characteristic.
