Abstract

Abstract A multimode camera comprises means for independently setting an aperture and a shutter speed to their optional values, means for selectively setting an AV-TV characteristic line in accordance with the aperture and shutter speed which have been set by the independently setting means, means for storing the AV-TV characteristic line which have been selected by the selectively setting means in accordance with a lens identification number of a lens barrel mounted on the camera, and means for unequivocally reading out the AV-TV characteristic line which have been stored in the storing means in accordance with the lens identification number of the lens barrel when a power source is turned on and/or the lens barrel is mounted on a camera body.

Claim 2
Dependent Claim 136 words
A camera system, including a camera for use with any one of a plurality of interchangeable lenses, comprising: (a) variable setting means for variably setting a value associated with the taking of a picture; (b) signal output means for outputting a memory signal in order to store said variable set value in a memory area; (c) input means for inputting a different identification number assigned to each interchangeable lens; (d) memory means for storing said identification number inputted by said input means and said value set by said setting means in association with each other; (e) selection means for inputting an identification number responsive to the interchangeable lens mounted upon the camera; and (f) means for reading out from said memory means the variable set value associated with the identification number inputted by said selection means.
Claim 3
Independent Claim 162 words
A method for controlling the photographing operation of a camera capable of having any one of a plurality of camera accessories releasably mounted thereon and including memory means for storing data employed in the control of a photographing operation and an identification number associated with said data; means for calculating the values required for performing a photographing operation and means for controlling the camera according to the calculated values, said method comprising the steps of: (a) assigning an identification number to each camera accessory; (b) setting a value employed in the calculation of a photographing operation into the memory means, said value being associated with a particular camera accessory; (c) associating said value with the identification number for the camera accessory; (d) detecting the identification number of the camera accessory mounted upon the camera body; (e) selecting the said value stored in memory associated with the identification number detected; and (f) providing the set value selected from memory to the calculation means.
Claim 4
Independent Claim 162 words
A method for controlling the photographing operation of a camera capable of having any one of a plurality of camera accessories releasably mounted thereon and including memory means for storing data employed in the control of a photographing operation and an identification number associated with said data; means for calculating the values required for performing a photographing operation and means for controlling the camera according to the calculated values, said method comprising the steps of: (a) assigning an identification number to each camera accessory; (b) setting a value employed in the calculation of a photographing operation into the memory means, said value being associated with a particular camera accessory; (c) associating said value with the identification number for the camera accessory; (d) detecting the identification number of the camera accessory mounted upon the camera body; (e) selecting the said value stored in memory associated with the identification number detected; and (f) providing the set value selected from memory to the calculation means.
Claim 5
Dependent Claim 51 words
The method of the claim 2 further comprising the steps of storing standard program values in said memory; and selecting said standard program values from said memory when the identification number of the camera accessory mounted upon the camera fails to compare with any of the identification numbers in said memory.
Claim 6
Dependent Claim 176 words
A camera system, including a camera for use with anyone of a plurality of interchangeable camera accessories, comprising: variable setting means for variably setting a value associated with a taking of a picture; signal output means for outputting a memory signal in order to store said variable set value in a memory area; input means for inputting a different identification number assigned to each camera accessory; memory means responsive to the camera accessory mounted upon the camera for storing the identification number inputted by said input means and said value set by said setting means in association with each other; a coded member for storing an identification number; each of said camera accessories including means for releasably receiving one of said coded cards for altering the identification number of the camera accessory according to the coded card mounted in said receiving means; means responsive to the coded card contained within the camera accessory mounted upon the camera for selecting the data in the camera memory associated with the identification number presently contained within the camera lens.
Claim 7
Dependent Claim 176 words
A camera system, including a camera for use with anyone of a plurality of interchangeable camera accessories, comprising: variable setting means for variably setting a value associated with a taking of a picture; signal output means for outputting a memory signal in order to store said variable set value in a memory area; input means for inputting a different identification number assigned to each camera accessory; memory means responsive to the camera accessory mounted upon the camera for storing the identification number inputted by said input means and said value set by said setting means in association with each other; a coded member for storing an identification number; each of said camera accessories including means for releasably receiving one of said coded cards for altering the identification number of the camera accessory according to the coded card mounted in said receiving means; means responsive to the coded card contained within the camera accessory mounted upon the camera for selecting the data in the camera memory associated with the identification number presently contained within the camera lens.
