摘要： A single high resolution frame is obtained from a plurality of frames sampled from moving image data, regardless of movement of a subject included in the frames. Patches are provided in a plurality of frames including a reference frame and other frames. The patches are moved and/or deformed, and correspondent relationships are estimated for each frame. The other frames are coordinate converted based on the estimated correspondent relationships. Correlative values, which represent the degrees of correlation between the other frames and the reference frame, are calculated. The number of regions within the patches is changed, and the correlative values are calculated in the same manner. A synthesized frame is generated from the plurality of frames based on the correspondent relationship, which was estimated for the number of regions that yields the maximal correlation.

摘要： An image is picked up through sampling in a predetermined sampling pattern to acquire an image signal representing the image. Sampling information, which concerns the predetermined sampling pattern, is appended to the image signal, which has been acquired. The sampling information is information for discriminating checkered sampling and square sampling from each other. Different sharpness enhancement processing is performed on the image signal and in accordance with the sampling information to obtain a processed image signal. The different sharpness enhancement processing may be a processing in accordance with frequency characteristics of the image signal, which has been acquired, due to the sampling pattern.

摘要： Supplementary information related to original data is embedded in the original data without being lost or altered and without degrading the quality of the original data. A photographing condition regarding photographing of the original image data is generated as the supplementary information by supplementary information generating unit and stored on a network in a supplementary information database. Storage management information such as a URL address of where the supplementary information is stored is generated by storage management information generating unit and embedded the original image data by using deep layer encryption. The original image data in which the storage management information has been embedded are recorded in a recording medium. Since the storage management information has a smaller amount of data than the supplementary information, quality of the original data is not degraded even when the storage management information is embedded in the original image data.

摘要： When an external terminal requests transfer of an image data set, the external terminal does not need to request a profile. The external terminal can reproduce an image corresponding to an output characteristic thereof, even if the terminal does not have a specific function such as processing of standardized image data. An image storing unit of an image server stores image data sets respectively having characteristics corresponding to output characteristics of external terminals including the external terminal. The external terminal sends transfer instruction information for requesting image data transfer. A judgment unit judges the output characteristic of the external terminal, based on the transfer instruction information. An image selection unit selects one of the image data sets having a characteristic corresponding to the output characteristic of the external terminal, based on a result of judgment. The selected image data set is sent to the external terminal.

摘要： An image encoding method includes a step in which image data of components other than image data of components representing the transparency of an image is encoded from among image data of components which includes image data of components representing the transparency of the image, and a step in which an image file is created from image data of components encoded in the encoding step and image data of components other than image data of components encoded in the encoding step. Accordingly, because image data of components representing the transparency of the image is not encoded in the encoded image file, the image shape can be recognized. Moreover, because the image data of the remaining components is encoded, the security of the details of the image data can be maintained.

摘要： To acquire a high-resolution frame from a plurality of frames sampled from a video image, it is necessary to obtain a high-resolution frame with reduced picture quality degradation regardless of motion of a subject included in the frame. Because of this, between a plurality of contiguous frames FrN and FrNnull1, there is estimated a correspondent relationship. Based on the correspondent relationship, the frames FrNnull1 and FrN are interposed to obtain first and second interpolated frames FrH1 and FrH2. Based on the correspondent relationship, the coordinates of the frame FrNnull1 are transformed, and from a correlation value with the frame FrN, there is obtained a weighting coefficient null(xnull, ynull) that makes the weight of the first interpolated frame FrH1 greater as a correlation becomes greater. With the weighting coefficient, the first and second interpolated frames are weighted and added to acquire a synthesized frame FrG.

摘要： An original image signal, which represents an original image and are composed of original image signal components representing a plurality of sampling points, that are arrayed at predetermined intervals and in a lattice-like form, is obtained. A judgment is made as to whether an interpolation point belongs to an image edge portion, at which the change in the original image signal is sharp, or belongs to a flat portion, at which the change in the original image signal is unsharp. Interpolating operation processes, one of which is to be employed for the interpolation point, is changed over to each other in accordance with the results of the judgment. Interpolated image signal components corresponding to interpolation points are thereby obtained from the interpolating operation processes such that a visible image, in which a character pattern and an image edge portion are free from any step-like pattern and are sharp and a flat portion has an appropriate level of sharpness, can be reproduced from the interpolated image signal components.
