1. An electric camera comprising:

  • an image sensing device, with a light receiving surface having a quantity N of vertically arranged pixels, and an arbitrary quantity of pixels arranged horizontally, wherein N is greater than or equal to three times a quantity M of effective scanning lines of a display screen of a television system;

    a driver configured to drive the image sensing device to vertically mix or cull signal charges accumulated in individual pixels, at intervals of a quantity K of pixels, in order to produce a quantity of lines of output signals which corresponds to the quantity M of effective scanning lines, wherein the quantity K is an integer less than or equal to an integer portion of a quotient of N divided by M;

    a view angle change switch configured to input a request to change a view angle of a moving image; and

    a signal processing unit configured to generate image signals by using the output signals of the image sensing device;

    wherein when the request to change the view angle is to magnify an output image by the view angle change switch. the driver changes the quantity of K from afirst value K1 to a second value K2, in order to read out image signals with the same quantity of output lines from different areas on the imaging sensing device wherein the first value K1 is larger than the second value K2;

    wherein the signal processing unit generates the image signals with the same scanning lines.
