Patent ID: 7508428

Claim:
A noise restraint apparatus for a digital camera which has an imaging device for imaging a photographic subject, comprising: an outputting processor that outputs a vertical synchronous signal to said imaging device; and a controlling processor that controls an output cycle of said vertical synchronous signal; said output cycle set to a first cycle, for a first period which is the period before an exposure operation, in which a photographic subject is imaged by said imaging device, a second cycle which is longer than said first cycle, for a second period, while said exposure operation is performed, a third cycle which is shorter than said second cycle, for a third period which is the period where an operation mode of said imaging device is changed from a first mode for said exposure operation to a second mode for reading of data obtained in said exposure operation, after said exposure operation is terminated, and a fourth cycle which is longer than said third cycle, for a fourth period which is the period where said data obtained in said exposure operation is read from said imaging device for every field, after changing to said second mode.
