IMAGING APPARATUS
First Claim
1. An imaging apparatus, comprising:
- an optical system configured to form an optical image of an object;
an imaging element configured to image the optical image and produce image data at a frame frequency Ffs out of a frame frequency Ffr of NTSC system;
a frame memory configured to store the image data; and
a controller configured to progressively write the image data in the frame memory and interlacedly read out the image data from the frame memory at the frame frequency Ffr of NTSC system,wherein the frame memory is divided into at least three areas each comprising a writing-in area and a read-out area, andwherein the controller sequentially switches the areas of the frame memory and progressively writes one frame of image data in each area and interlacedly reads out one frame of image data from each area in sequence.

Abstract
An imaging apparatus, including an optical system forming an image of an optical image of an object; an imaging element imaging the optical image and producing image data at a frame frequency Ffs out of a frame frequency Ffr of NTSC system; a frame memory storing the image data; and a controller progressively writing the image data in the frame memory and interlacedly reading out the image data from the frame memory at the frame frequency Ffr of NTSC system. The frame memory is divided into at least three areas comprising a writing-in area and a read-out area, wherein the controller sequentially switches the areas of the frame memory and progressively writes one frame of image data in each area and interlacedly reads out one frame of image data from each area in sequence.
