Abstract
In a camera having an exposure setting device which corrects exposure control automatically set according to a DX code, the setting device is arranged to automatically change the value of the set exposure value to a predetermined different value and to set the different value as the exposure value when the automatically set exposure value is at a predetermined specific value.
Claims11
A camera having a film information setting device, comprising:
- a) a film information reading circuit arranged to automatically read film information of a film loaded in the camera;
- b) a setting circuit for setting a data of value corresponding to the film information read by said film information reading circuit, said setting circuit setting a data of a first value when the read film information is a first information and a data of a second value when the read film information is a second information;
- and
- c) a modification circuit for modifying the correspondency of the data value to the film information set by the setting circuit, said modification circuit detecting the read film information and setting a data of a value different from the first value in the setting circuit when the read film information is the first information.
A camera having a film information setting device, comprising:
- a) a film information reading circuit arranged to automatically read film information of a film loaded in the camera;
- b) a data setting circuit for setting a data of a predetermined value corresponding to each of the film informations read by the film information reading circuit, said data setting circuit setting a data of a first value at least when the film information is a first information;
- and
- c) a modification circuit for modifying the relation between the read film information and the data value, said modification circuit detecting the film information read by the reading circuit and setting a data of a second value in the data setting circuit when the detected information is the first information.
A camera having a film information setting device, comprising:
- a) a film information reading circuit arranged to automatically read film information of a film loaded in the camera;
- b) a memory circuit having a plurality of memory portions, each portion having predetermined data memorized therein;
- c) a selection circuit for selecting a predetermined memory portion according to the film information read by the film information reading circuit;
- d) a setting circuit for setting the data of the memory portion selected by the selection circuit as data corresponding to the read film information;
- and
- e) a modification circuit for modifying predetermined data memorized in the memory portion.
A camera having a film information reading circuit arranged to automatically read a film information of a film loaded in said camera and to set a corresponding camera operating value and a manual information setting circuit arranged to set, in response to an operation of a manual operation member, a camera operating value to a desired camera operating value different from the camera operating value corresponding to the film information value read by said reading circuit, comprising:
- a) a display circuit arranged to display the camera operating value set by said manual information setting circuit;
- b) a display operation member arranged to be operated for causing said display circuit to display the camera operating value corresponding to the film information value read by said reading circuit after the desired camera operating value is set by said manual information setting circuit;
- and
- c) a control circuit for transmitting the information value set in the manual information setting circuit as an information for exposure control to an exposure control circuit portion even when the film information value read by the reading circuit is displayed by the display circuit insofar as the information is set in the manual information setting circuit.
