Claim 5
Dependent Claim
83 words
An apparatus according to claim 3, wherein, when said image pickup mode selecting means selects said 3D image pickup mode and a correlationship between distributions of luminance of said first image picked up by said first image pickup means and said second image picked up by said second image pickup means lies in said first state, then said exposure amount determining means substitutes a value of one of said determined first and second exposure amounts as a value of the other one thereof.
Claim 6
Dependent Claim
82 words
An apparatus according to claim 1, wherein said exposure amount determining means comprises judging means for judging whether a correlationship of distributions of luminance between said first image picked up by said first image pickup means and said second image picked up by said second image pickup means lies in a first state or a second state, wherein said first state is characterized in that said correlationship is closed and said second state is characterized in that said correlationship is not closed.
