Abstract
Abstract An image synthesizing device in which partial images can be rapidly processed (for example, by enlarging, reducing, turning) and synthesized. When synthesizing information for partial images stored in a partial image storage portion (1, 31) is calculated by a synthesizing data calculating portion (5, 35), accessible rectangular areas, which consist each of a plurality of pixel rows and columns, of partial images stored in the partial image storage portion (1, 31) are accessed one by one by a partial image accessing portion (2, 32) and each of accessed areas is processed by enlarging or reducing or tilting on the basis of the calculation results given from the synthesizing data calculating portion (5, 35). The processed partial images whose areas have been enlarged, reduced or tilted, are synthesized by a partial image synthesizing portion (3, 33) on the basis of the synthesizing information, and a synthesized image is stored in a synthesized image storage portion (4, 34).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
183 words
An image synthesizing device comprising: a partial image storage portion (1, 31) for storing a plurality of partial images taken from a part of an object, said images having adjoining portion overlapped each other; a synthesizing data calculating portion (5, 35) for calculating synthesizing information for a plurality of the partial images stored in the partial image storage portion (1, 31) ; a partial image accessing portion (2, 32) for accessing one by one accessible tetragonal areas, each of which consists of a plurality of pixel rows and columns, and into which each partial image is divided for being stored and processed in the partial image storage portion (1, 31), on the basis of the synthesizing information obtained by the synthesizing data calculating portion (5, 35) ; a partial image synthesizing portion (3, 33) for synthesizing partial images processed by the partial image accessing portion (2, 32) according to the synthesizing information from the synthesizing data calculating portion (5, 35) ; and a synthesized image storage portion (4, 34) for storing a synthesized image obtained by the partial image synthesizing portion (3, 33).
Claim 2
Dependent Claim
31 words
An image synthesizing device according to claim 1, characterized in that the partial image accessing portion (2, 32) makes an access to each of accessible rectangular areas of each partial image.
Claim 3
Dependent Claim
31 words
An image synthesizing device according to claim 1, characterized in that the partial image accessing portion (2, 32) makes an access to each of accessible square-block areas of each partial image.
Claim 4
Dependent Claim
45 words
An image synthesizing device according to claim 1, characterized in that the partial image accessing portion (2, 32) is capable of enlarging or reducing in size each partial image by increasing or decreasing the number of pixel rows or columns in each accessible area therein.
Claim 5
Dependent Claim
51 words
An image synthesizing device according to claim 1, characterized in that the partial image accessing portion (2, 32) is capable of enlarging or reducing in size each partial image by increasing or decreasing the number of pixel rows or columns in boundary portions of adjacent accessible areas of each partial image.
Claim 6
Dependent Claim
64 words
An image synthesizing device according to claim 2, characterized in that the partial image accessing portion (2, 32) is capable of bringing each partial image into turned state by displacing a pixel row or column in each accessible rectangular area of each partial image and at the same time by increasing or decreasing the number of pixels in the pixel row or column therein.
Claim 7
Dependent Claim
40 words
An image synthesizing device according to claim 3, characterized in that the partial image accessing portion (2, 32) is capable of bringing a partial image into turned state by displacing relative arrangement of adjoining accessible block areas of partial images.
Claim 8
Dependent Claim
55 words
An image synthesizing device according to claim 1, characterized in that the partial image synthesizing portion (3, 33) previously calculates a displacement to be producible between in a first partial image and a last partial image of sequentially synthesizable adjacent partial images and allocates the calculated displacement to every combination of sequentially adjoining partial images.
Claim 9
Dependent Claim
53 words
An image synthesizing device according to claim 1, characterized in that the partial image synthesizing portion (3, 33) previously calculates a displacement to be producible between a first partial image and a last partial image of sequentially synthesizable adjacent partial images and compensates the calculated displacement by deforming the last synthesizable partial image.
Claim 10
Dependent Claim
33 words
An image synthesizing device according to claim 9, characterized in that the partial image synthesizing portion (3, 33) compensates the calculated displacement by changing every accessible area of the last synthesizable partial image.
Claim 11
Dependent Claim
34 words
An image synthesizing device according to claim 1, characterized in that the partial image synthesizing portion (3, 33) changes gradation by changing a brightness ratio of pixels of overlapped portions of every partial image.
Claim 12
Dependent Claim
64 words
An image synthesizing device according to claim 1, characterized in that it is further provided with a partial image deforming portion (76) which is capable of deforming each partial image read from the partial image storage portion (1, 31, 75) so that an image synthesized from partial images may be stored entirely with no overflowing part in the synthesized storage portion (4, 34, 78).
Claim 13
Dependent Claim
53 words
An image synthesizing device according to claim 1, characterized in that the synthesized image storage portion (4, 34) is capable of separately recording a part of synthesized partial images, said part being overflowable from the synthesized image storage portion (4, 34), in a vacant area of the synthesized image storage portion (4, 34).
