- the portrait right and copyright of the original image data file A can be divided.
- the thinning rule since the thinning rule is included in the image data file after division, the thinning rule can be changed when the electronic still camera side divides the image data. That is, in the first to third embodiments, since the thinning rule is determined in advance, all the divided image data files are reproduced, and each of the complemented data portions is converted to another image data file.
- the original image data file A before the division can be restored by replacing the data with the data of the original image data file A.
- the original image data cannot be restored without understanding the thinning rule. Therefore, in the fourth embodiment, the original image data file before division can be restored even if the thinning rule is changed by including the thinning rule in the divided image data file.
- a data file in which only the thinning rules are recorded may be generated.
- Fig. 6 illustrates the unknown thinning-out division, which divides one original image data file A into two image data files A1d and A2d, and generates a data file R that stores the thinning rules at the time of division.
- FIG. 6 the data of the original image data file A is the same as the configuration of FIG. 2 described above.
- Image data of the first image data file A 1 d after splitting into two image data files? ? According to the thinning rule stored in the file R. That is, the data given for the first image data file after division by the thinning rule matches the data of the original image data file A.
- the second image data file after splitting into two image data files A2c image data? ? The content of follows the thinning rule stored in the data file R. That is, the data given for the second image data file after division by the thinning rule matches the data of the original image data file A.
- the image data section is the minimum data required for reproducing an image, and is, for example, data that is required in a standard such as the JPEG format.
- the additional information section is data such as description of an image (caption), shooting information (shutter speed, exposure time, etc.), and audio caption.
- the image data portion of the original image data file A is divided into N image data files and registered, and the image constituted by the supplementary data is used as the (N + 1) th file. An image data file having a data section and an additional information section is registered.
- the N + 1st file uses, for example, data for reproducing black as the complementary data in the image data portion. Further, the additional information included in the original image data file A is used for the additional information section of the (N + 1) th file.
- the portrait right and the copyright of the image based on the original image data file A can be divided. Further, the data of the additional information part of the original image data file A can be registered in the (N + 1) th file after division.
- the additional information portion of the original image data file A is divided into the first to Nth image data files and registered, and the additional information portion is added to the (N + 1) th file.
- the example of registering without dividing is described. Instead, the additional information section may be registered in the first to Nth image data files after division without dividing the additional information section.
- the additional information section may be divided without dividing the image data section.
- the additional information section is divided into items such as captions and shooting information. Then, the combination of the caption and the image data of the original image data file A is registered as a divided image data file A 1 e, and the shooting information and the image data of the original image data file A are registered. Is registered as the image data file A 2 e in combination with the above.
- the right to obtain the additional information part by the original image data file A can be divided. Further, each of the image data portion and the additional information portion of the original image data file A is divided, and the image data portion after the division and the additional information portion after the division are combined, respectively, to obtain the image data portion.
- the files may be registered as A 1 f and A 2 f.
- the decimation rule is determined so that the information of the image data part of the original image data file A before division is equally divided by 1 ZN for each of the N image data files after division. That is explained.
- the division ratio may be changed by weighting the thinning rule. In this case, the portrait right and copyright of the original image data file A can be divided unequally.
- each of the divided multiple image data files includes a part of the image data of the original image data file A, and the missing data compared with the original image after the division is supplemented.
- the image data file after division may be generated by filling in the insufficient data.
- FIG. 7 is a diagram illustrating pixel thinning division without using supplementary data.
- the original image data file A before the division is the same as in Fig. 2 above.
- the first pixel of the first image data file A 1 ′ after division is composed of data 11, data 12, and data 13.
- the second pixel is composed of data 41, data 42, and data 43.
- the data of the (1 + Nx) pixel of the original image data file A is substituted as the data of the (1 + x) pixel.
- N is the number of divisions
- X is 0, 1, 2, ....
- the first pixel has data 21 and data
- the second pixel is formed by data 51, data 52, and data 53.
- the data of the (2 + Nx) pixel of the original image data file A is substituted as the data of the (1 + x) pixel.
- N is the number of divisions
- X is 0, 1, 2, ....
- the first pixel has data 31 and data
- the second pixel is composed of data 61, data 62, and data 63.
- N is the number of divisions
- x is 0, 1, 2 ...
- the image data file after division is created by filling the data interval without compensating for the data that is insufficient after division, the increase in the data size caused by the increase in the number of files due to division can be suppressed and used. This saves memory capacity.
- the camera may be configured to select the division method according to the first to fifth embodiments.
- the present invention can be applied to a document creation device such as a video camera, a recording device, or a word processor. That is, the present invention is not limited to a still image data file, but can be applied to a moving image data file, a three-dimensional image format file, an audio format file, and a text format file.
- the present invention can also be applied to a case where a data file is imported to a personal computer and divided.
- a program for executing the above-described various division methods is stored in the personal computer in advance, and the original image file is read from a memory card or the like to perform the above-described image division. Therefore, the personal computer functions as a data file generator.
