Abstract:
1. An electronic camera, comprising: an imager, having an imaging surface capturing an optical image through a zoom lens, which repeatedly outputs an electronic image corresponding to the optical image; a lens mover which moves said zoom lens between a wide end and a tele end in order to change a zoom magnification in parallel with an image outputting process of said imager; a reducer which reduces the number of pixels of the electronic image outputted from said imager so as to create a reduced image; an extractor which extracts a reduced image belonging to an extraction area of a predetermined size, out of the reduced image created by said reducer; and a controller which changes the number of pixels of the reduced image to be created by said reducer in a direction which is the same as a changing direction of the zoom magnification by said lens mover, wherein said controller sets the number of pixels of the reduced image to a first number and a second number respectively corresponding to the wide end and the tele end, and changes the number of pixels of the reduced image along a straight line that connects a first coordinate specified by the wide end and the first number and a second coordinate specified by the tele end and the second number on a graph represented by two coordinate axes respectively defining a position of said zoom lens and the number of pixels of the reduced image, wherein the first number is equivalent to the predetermined size.
