Abstract

Abstract An image processing apparatus comprises an image storing device and an image inputting device, in which a parameter determining circuit compares an image input through the image inputting device with an image stored in the image storing device to calculate parameters for correction and in which the input image is corrected by a correction method different from that effected on the image having been stored, then to be combined therewith. The processing is sequentially effected on time-serially input images to produce a higher resolution image in the image storing device as compared with the input images.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 191 words
An image processing apparatus comprising: image inputting means for successively inputting images into said image processing apparatus; input processing means for processing inputting images; and image storing means for storing images outputted from said image processing means; wherein said input processing means includes image comparing means for comparing an image previously stored in said image storing means with an image currently inputted through said image inputting means to obtain a difference between the image previously stored and the image currently inputted; image correction means for correcting the image previously stored in said storing means and the image currently inputted through said inputting means respectively in different ways based upon the difference obtained by said image comparing means, said image correction means including means for making an affine transformation of the image stored in said image storing means and means for making a parallel displacement of the image input through said image inputting means; and image combining means for combining the corrected images with each other to supply said image storing means with a combined image, said image combining means including means for an addition of both images by a weighted mean.
Claim 2
Dependent Claim 191 words
An image processing apparatus comprising: image inputting means for successively inputting images into said image processing apparatus; input processing means for processing inputting images; and image storing means for storing images outputted from said image processing means; wherein said input processing means includes image comparing means for comparing an image previously stored in said image storing means with an image currently inputted through said image inputting means to obtain a difference between the image previously stored and the image currently inputted; image correction means for correcting the image previously stored in said storing means and the image currently inputted through said inputting means respectively in different ways based upon the difference obtained by said image comparing means, said image correction means including means for making an affine transformation of the image stored in said image storing means and means for making a parallel displacement of the image input through said image inputting means; and image combining means for combining the corrected images with each other to supply said image storing means with a combined image, said image combining means including means for an addition of both images by a weighted mean.
Claim 3
Dependent Claim 33 words
An image processing apparatus according to claim 1, wherein said image comparing means includes means for detecting parameters of the affine transformation and the parallel displacement by comparing the images with each other.
Claim 4
Dependent Claim 43 words
An image processing apparatus according to claim 2, wherein said image comparing means includes means for detecting the parameters of the affine transformation and the parallel displacement from motion vectors at a plurality of representative points each having a coordinate value preliminarily set.
Claim 5
Dependent Claim 36 words
An image processing apparatus according to claim 3, wherein said image comparing means includes means for determining the coordinate values of the representative points in accordance with statistical values of pixel data in the input image.
Claim 6
Dependent Claim 26 words
An image processing apparatus according to claim 2, wherein said image comparing means includes means for comparing the images after contracting said images to be compared.
Claim 7
Dependent Claim 17 words
An image processing apparatus according to claim 1, wherein said image inputting means has a gyro system.
Claim 8
Dependent Claim 16 words
An image processing apparatus according to claim 1, wherein said image inputting means has a vibrator.
