Abstract:
A digital camera including a housing and a lens having an adjustable aperture associated therewith for admitting light into said housing and onto an image sensing device for converting the light to an electrical signal, said camera comprising:a) a camera setting adjustment system responsive to the electrical signal indicative of the object to be photographed for automatically adjusting the aperture to an optimal setting relative to an ambient lighting condition surrounding the object to be photographed; b) a fixed focus mode algorithm for determining a focal point based on the adjusted aperture, for moving the lens to a focal point corresponding to said adjusted aperture, and for retaining the focal point corresponding to the adjusted aperture as a default setting; and c) an automatic focus mode algorithm responsive to the optimal setting of the adjustable aperture for moving the lens to a determined focal point upon receipt of an externally generated activation command of said automatic focus mode algorithm.
