Patent ID: 7142236

Claim:
A digital zoom apparatus which creates zoomed image data by performing a zoom process on image data stored in a first memory such that a first number of pixels are assigned to each address, comprising: a specifier for specifying a zoom start pixel on the basis of a zoom magnification; a second memory having addresses each of which a second number of pixel(s) smaller than the first number of pixels is assigned to; a transferor for transferring the image data from said first memory to said second memory with reference to an address to which the zoom start pixel is assigned; and a zoom processor for performing the zoom process on the image data transferred to said second memory with reference to the zoom start pixel, wherein said specifier specifies the zoom start pixel on the basis of an integer value acquired by multiplying a reciprocal of the zoom magnification by a predetermined value and the number of pixels of the image data stored in said first memory in a zoom direction, and said digital zoom apparatus further comprises a renewer for successively renewing the integer value.
