Estimating the term…
An imaging apparatus has the function of an optical zoom which optically converts the magnification of an image and the function of an electronic zoom which changes the size of an image by electrical signal processing. The function of the electronic zoom at least operates when the optical zoom is not set at the telephoto end. A total magnification is determined by changing magnification by the optical zoom and changing magnification by the electronic zoom. A pixel count s1 of an electronic imaging device, a pixel count s2 of a rectangle including the pixels on an imaging device which are used by the electronic zoom, and a pixel count s3 of an output satisfy s1≧s2>s3 or s1>s2≧s3.
An imaging apparatus that samples an optically formed image by using an electronic imaging device to acquire the image as image data, comprising optical zoom means that optically converts a magnification of an image and electronic zoom means that changes a size of an image by electrical signal processing, wherein the electronic zoom means at least operates when the optical zoom means is not set at a telephoto end, so that a total magnification is determined by changing magnification of the optical zoom means and changing magnification of the electronic zoom means, and a pixel count s1 of the electronic imaging device, a pixel count s2 of a rectangle including pixels on the electronic imaging device that is used by the electronic zoom means, and a pixel count s3 of an output satisfy s1≧s2>s3 or s1>s2≧s3.
