Embodiment approach 1

[0087] FIG. 1 is a diagram for explaining Embodiment 1 of an image processing device according to the present invention, and is a block diagram showing a configuration on an encoding side. Its structure can be roughly divided into: image data input unit 1; square area segmentation unit 2; recursive triangular area segmentation unit 3; triangular area segmentation control unit 4; encoded data generation unit 5; encoded data output unit 6.

[0088] As shown in Figure 2, the image data input unit 1 has: a pixel data input unit 11, which inputs each pixel data; a color component separation unit 12, which separates the color data of the input pixel into each color component; a color conversion unit 13, It converts from RGB to YUV data according to the separated color data, for example; a data thinning unit 14, which performs data thinning as needed. In addition, image data input into this image data input unit 1 can be conceived of, for example, image data from a camera, image data...

Embodiment approach 2

[0142] In this second embodiment, a process of decoding data encoded in the above-mentioned first embodiment will be described.

[0143] FIG. 26 is a diagram illustrating a second example of an image processing device according to the present invention, and is a block diagram showing a configuration on the decoding side of the first embodiment. The structure of the decoding side is roughly divided into: coded data input unit 11; coded data analysis unit 12; recursive triangular area synthesis unit 13; triangular area synthesis control unit 14; square area synthesis unit 15; image data output unit 16.

[0144] The recursive triangular area synthesizing unit 13 has at least: a shape type storage unit 131, which stores the types of triangles obtained by division (in the above-mentioned embodiment 1, there are 8 types of #1 type to #8 type, so in this In Embodiment 2, there are also #1 type to #8 type (these 8 types) of triangle types; vertex pixel value storage unit 132, which st...

Embodiment approach 3

[0167] In Embodiments 1 and 2 described above, when the image data to be processed is not square, and the square area is extracted from the image data, as described with reference to FIG. 6 , by dividing the image data into a plurality of square However, the third embodiment is an example in which one square is generated by performing image processing for transforming non-square image data into a square. Next, Embodiment 3 will be described.

[0168] FIG. 35 is a diagram illustrating an image processing device according to Embodiment 3 of the present invention, and is a block diagram showing a configuration on an encoding side. The configuration on the encoding side shown in FIG. 35 is only the configuration in FIG. 1 used in the description of the first embodiment above, and the square region dividing unit 2 (see FIG. 1 ) is replaced by the image region squarer unit 10 as its constituent element. (Refer to FIG. 35 ), other structures are the same as those in FIG. 1 , so the ...

Abstract

A method, a device ,and a program for image processing, to facilitate processing such as image scaling, resolution conversion, and minute refining for only a part of an image, in order to improve the processing speed and to attain miniaturization of circuit scale. The device comprises an image data input means 1 for inputting and storing an image, a square region segmenting means 2 for segmenting the inputted image to one or more square regions, a recursive triangular region segmenting means 3 for segmenting each segmented square region to a triangular region recursively, a triangular region segmentation control means 4 for performing segmentation control to the recursive triangular region, a coded data generating means 5 for encoding the segmented triangular region, and a coded data output means 6 for outputting the generated coded data. In addition, the number of pixels contained in one side of a square region generated by the square region segmenting means 2 should be the N-th power of 2 + 1 (N is a natural number).

Description

technical field [0001] The invention relates to an image processing method, an image processing device and an image processing program. In particular, it relates to an image processing method, an image processing device, and an image processing program that take an image as a square area, divide the square area into triangular areas, and perform image processing on the divided triangular areas. Background technique [0002] Patent Document 1: JP-9-84002 Gazette [0003] Patent Document 2: Japanese Patent Application Laid-Open No. 9-191409 [0004] Patent document 3: Japanese Patent Application Laid-Open No. 11-298897 [0005] Patent Document 4: JP-A-2000-125294 [0006] Due to the popularization of the network environment, information with a large amount of data such as images can also be used as a communication object very commonly, and it is very common to process images on various machines. At this time, even if it is the same image data, it is required to efficiently...
