Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A camera comprising: (a) exposure control means for carrying out at least a shutter speed priority exposure control mode and a shutter speed leading programmed exposure control mode; (b) focusing control means for carrying out at least a servo type focusing control mode and a one-shot type focusing control mode; and (c) first mode setting means operatively connected to said focusing control means to automatically set said focusing control means in said servo type focusing control mode when said automatic exposure control means carries out said shutter speed priority exposure control mode or said shutter speed leading programmed exposure control mode.
Claim 2
Dependent Claim
101 words
A camera comprising: (a) exposure control means for carrying out at least a shutter speed priority exposure control mode and a shutter speed leading programmed exposure control mode; (b) focusing control means for carrying out at least a servo type focusing control mode and a one-shot type focusing control mode; and (c) first mode setting means operatively connected to said focusing control means to automatically set said focusing control means in said servo type focusing control mode when said automatic exposure control means carries out said shutter speed priority exposure control mode or said shutter speed leading programmed exposure control mode.
Claim 3
Dependent Claim
70 words
A camera according to claim 1, wherein said exposure control means further has at least an aperture priority exposure control mode and an aperture leading programmed mode, and further including second mode setting means for automatically setting said focusing control function in said one-shot type focusing control mode when said exposure control means is set to said aperture priority exposure control mode or said aperture leading programmed exposure control mode.
Claim 4
Dependent Claim
95 words
A camera comprising: (a) exposure control means for carrying out at least an aperture priority exposure control mode and an aperture leading programmed exposure control mode; (b) focusing control means for carrying out at least a one-shot type focusing control mode and a servo type focusing control mode; and (c) mode setting means operatively connected to said focusing control means to automatically set said focusing control means to said one-shot type focusing control mode when said exposure control means carries out said aperture priority exposure control mode or said aperture leading programmed exposure control mode.
Claim 5
Dependent Claim
95 words
A camera comprising: (a) exposure control means for carrying out at least an aperture priority exposure control mode and an aperture leading programmed exposure control mode; (b) focusing control means for carrying out at least a one-shot type focusing control mode and a servo type focusing control mode; and (c) mode setting means operatively connected to said focusing control means to automatically set said focusing control means to said one-shot type focusing control mode when said exposure control means carries out said aperture priority exposure control mode or said aperture leading programmed exposure control mode.
Claim 6
Dependent Claim
83 words
A camera comprising: (a) exposure control means for carrying out at least a shutter speed priority exposure control mode; (b) focusing control means for carrying out at least a servo type focusing control mode and a one-shot type focusing control mode; and (c) first mode setting means operatively connected to said focusing control means to automatically set said focusing control means to said servo type focusing control mode when said automatic exposure control means carries out said shutter speed priority exposure control mode.
Claim 7
Dependent Claim
83 words
A camera comprising: (a) exposure control means for carrying out at least a shutter speed priority exposure control mode; (b) focusing control means for carrying out at least a servo type focusing control mode and a one-shot type focusing control mode; and (c) first mode setting means operatively connected to said focusing control means to automatically set said focusing control means to said servo type focusing control mode when said automatic exposure control means carries out said shutter speed priority exposure control mode.
Claim 8
Dependent Claim
71 words
A camera according to claim 4 wherein said exposure control means further has an aperture priority exposure control mode and an aperture leading programmed exposure control mode, and further including second mode setting means responsive to setting of said exposure control means to said aperture priority exposure control mode or said aperture leading programmed exposure control mode for automatically setting said focusing control function to said one-shot type focusing control mode.
Claim 9
Dependent Claim
79 words
A camera comprising: (a) exposure control means for carrying out at least an aperture priority exposure control mode; (b) focusing control means for carrying out at least a servo type focusing control mode and a one-shot type focusing control mode; and (c) first mode setting means operatively connected to said focusing control means for automatically setting said focusing control means to said one-shot focusing control mode when said exposure control means carries out said aperture priority exposure control mode.
Claim 10
Dependent Claim
79 words
A camera comprising: (a) exposure control means for carrying out at least an aperture priority exposure control mode; (b) focusing control means for carrying out at least a servo type focusing control mode and a one-shot type focusing control mode; and (c) first mode setting means operatively connected to said focusing control means for automatically setting said focusing control means to said one-shot focusing control mode when said exposure control means carries out said aperture priority exposure control mode.
Claim 11
Dependent Claim
70 words
A camera including an automatic in-focus controlling device having at least a one-shot type in-focus control mode to enable self-timer photography, comprising: (a) control means for performing said one-shot type in-focus control mode; and (b) a member for setting a control mode of the automatic in-focus control device, said member being functionally connected to said control means to forcibly effectuate said control means when said self-timer photography is carried out.
Claim 12
Dependent Claim
70 words
A camera including an automatic in-focus controlling device having at least a one-shot type in-focus control mode to enable self-timer photography, comprising: (a) control means for performing said one-shot type in-focus control mode; and (b) a member for setting a control mode of the automatic in-focus control device, said member being functionally connected to said control means to forcibly effectuate said control means when said self-timer photography is carried out.
