摘要： To enable obtainment of a composite image including a movement trajectory of a moving body, even from a moving image including a background. Sampling means samples frames from moving image data. First mask frame calculating means calculates mask frames including mask regions, which correspond to positions of the moving body on the frames. Second mask frame calculating means accumulates and binarizes the mask frames to calculate a reference mask frame. Region cutout means masks the frames by using the mask frames and the reference mask frame to cut out moving body regions, which correspond to a moving body, from the frames. Composing means overwrites moving body regions on one of the frames in chronological order to obtain a composite image, which includes the movement trajectory of the moving body.

摘要： In order to accurately remove an unnecessary periodic noise component from an image, a reconstruction unit generates a reconstructed image without a periodic noise component by fitting to a face region detected in an image by a face detection unit a mathematical model generated according a method of AAM using a plurality of sample images representing human faces without a periodic noise component. The periodic noise component is extracted by a difference between the face region and the reconstructed image, and a frequency of the noise component is determined. The noise component of the determined frequency is then removed from the image.

摘要： A motion detecting apparatus includes a comparator and motion estimator. The comparator compares a threshold and an input absolute error, and selects as a selected motion vector, one of a predetermined motion vector and an input motion vector based on the comparison result. The motion estimator determines a reference video signal based on the selected motion vector, and determines an absolute error from the determined reference video signal and an input video signal to output the determined absolute error. Then, the motion estimator estimates a motion vector from the determined reference video signal and the input video signal such that the absolute error is minimum, to output a motion vector determined based on the estimated motion vector and the selected motion vector.

摘要： An image compression apparatus capable of compressing an input image that includes a predetermined target object at a high compression ratio while allowing high quality image restoration. In the apparatus, the input image is reduced and compressed. A region of interest corresponding to a predetermined target object is set in the input image. A partial area image of an expanded image of the compressed reduced image corresponding to the region of interest is converted to a high resolution image by applying a prediction process that uses a learning result obtained by learning the predetermined object in advance. With respect to the region of interest portion, a differential image between the image converted to the high resolution and the input image is generated and encoded. Reduced image compression data and differential image encoded data are outputted.

摘要： When trimming is performed on a photograph image obtained by a photography apparatus, a plurality of trimming range candidates is set by analyzing the photograph image. A judgment is made as to whether the zoom magnification ratio of the photography apparatus during photography corresponds to a predetermined limit, the limit being a maximum zoom magnification ratio or a minimum zoom magnification ratio that can be set by the photography apparatus. A trimming range is set by selecting one of the plurality of trimming range candidates. If the zoom magnification ratio is judged to be a magnification ratio corresponding to the predetermined limit, a trimming range candidate that has a smaller or larger range than that of a trimming range candidate selected if the zoom magnification ratio is judged to be a magnification ratio that does not correspond to the predetermined limit is selected as the trimming range.

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 FrN+1, there is estimated a correspondent relationship. Based on the correspondent relationship, the frames FrN+1 and FrN are interposed to obtain first and second interpolated frames FrH1 and FrH2. Based on the correspondent relationship, the coordinates of the frame FrN+1 are transformed, and from a correlation value with the frame FrN, there is obtained a weighting coefficient α (x′, y′) 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.
