Abstract:
1. A digital camera comprising: an image sensor for generating an image signal by photoelectronically converting an optical image of an object; an exposer for exposing said image sensor in response to a timing signal every predetermined time period; a reader for reading said image signal generated by exposing of said exposer from said image sensor at a first speed corresponding to said predetermined time period; a processor for performing a predetermined process on the basis of said image signal read by said reader at said first speed; an instructor for issuing a photographing instruction to photograph a desired object; and a first changer for changing a reading speed of said reader to a second speed lower than said first speed, wherein the photographing instruction includes a main-exposure instruction that initiates a main exposure operation and an image recording operation, and said first changer initiates the changing of the reading speed of said reader to the second speed after the main-exposure operation is completed and prior to reading the image signal of said desired object from the image sensor, and the reading speed of said reader is maintained at the second speed while reading the image signal of said object from the image sensor.
