Abstract:
A camera comprising:image pick-up means for outputting image data in accordance with incident light; first pick-up control means for obtaining first image data output from the image pick-up means under a condition where an incident light path of the image pick-up means is opened; second pick-up control means for obtaining second image data output from the image pick-up means under a condition where the incident light path of the image pick-up means is closed; means for correcting the first image data obtained by the first pick-up control means based on the second image data obtained by the second pick-up control means; first nonlinear processing means for subjecting the image data output from the image pick-up means to nonlinear processing; and means for prohibiting the nonlinear processing for the image data by said first nonlinear processing means when the first and second image data are obtained by the first and second pick-up control means, wherein said first pick-up control means and said second pick-up control means obtain the fist image data and the second image data which are not subjected to the nonlinear processing by said first nonlinear processing means.
