An image processing device includes: a calculator that calculates a gray scale histogram for each color component of an image signal; a calculator that calculates, for each color component, a maximum and a minimum of classes having a frequency greater than zero in the gray scale histogram; a determiner that generates, for each color component, a histogram having classes each having an absolute difference value between the frequencies of adjacent classes in the gray scale histogram, and compares the absolute difference values in the histograms with a value to determine, from the presence or absence of an absolute difference value exceeding the value, an image type of the image; a generator that generates a gray scale correction curve from the calculated maximum and minimum for each color component; and a corrector that performs gray scale correction on the image signal using the gray scale correction curve.

Image processing device and image processing method

In an image processing apparatus, maximum values and minimum values of the classes of respective color components are calculated; the largest value among the maximum values of the color components is found as an all-color maximum value, color correction curves are generated, on the basis of the maximum and minimum values of the respective color components and the all-color maximum value, for color components other than the color component whose maximum value is equal to the all-color maximum value, and the color correction curves are used to perform corrections on the respective color components of the image signal. The color correction curves are generated for performing corrections such that, after the corrections, the maximum value of each color component is approximately equal to the all-color maximum value. Alternatively, the color correction curves are generated for performing corrections such that, after the corrections, the minimum value of each color component is approximately equal to an all-color minimum value. Color casts arising from lighting effects at the time of imaging are corrected, and image contrast can be heightened.

When a vehicle navigation system is manipulated by taking pictures of a user hand motion and gesture with a camera, as the number of apparatuses and operational objects increases, the associated hand shapes and hand motions increase, thus causing a complex manipulation for a user. Furthermore, in detecting a hand with the camera, when the image of a face having color tone information similar to that of a hand appears in an image taken with a camera, or outside light rays such as sun rays or illumination rays vary, detection accuracy is reduced. To overcome such problems, a manipulation input device is provided that includes a limited hand manipulation determination unit and a menu representation unit, whereby a simple manipulation can be achieved and manipulation can accurately be determined. In addition, detection accuracy can be improved by a unit that selects a single result from results determined by a plurality of determination units, based on images taken with a plurality of cameras.

[Means for solution] The music-segment detection method provided with a data input step of inputting data including an audio signal and a video signal; a plurality of candidate-music-segment detection steps of detecting, from the audio signal, respective candidate music-segments in the input data, based on criteria different from each other; a change-point detection step of detecting a change point in the input data, based on a distinctive change in the audio signal and/or on a distinctive change in a video signal; and a music-segment detection step of detecting a music segment, based on the plurality of detected candidate-music-segments and on the detected change point.

A recording medium () for a reservation of video recording of a program holds encoded compressed video information () related to the program, a reservation set command () for setting a reservation of the program, and program attribute information () including at least a video recording reservation start date and time. When a viewer makes a selection to set a reservation of video recording while watching a preview video () based on the encoded compressed video information of the recording medium in a video recording/reproducing apparatus, the video recording/reproducing apparatus acquires the program attribute information () in accordance with the reservation set command () in the recording medium (), thereby setting a reservation of video recording. Thus, there in no need of manual operation for inputting information required for setting a reservation of video recording and it is possible to easily set a reservation of video recording of the program while watching and listening to program-related information.

Problem: It is to automatically recognize CM-broadcast periods, while video-recording television broadcast, without interfering with simultaneous access action to the medium for video-recording the television broadcast. Means to Solve the Problem: By detecting transition points in an audio video signal of a television broadcast, recognizing a CM broadcast period when the points occur at intervals specific to CM-broadcast periods, and controlling to record into a recording medium at a predetermined timing, time information of plural CM-broadcast periods determined to be continuous, the frequency to access the recording medium can be reduced, which results in simultaneously recording inputted video images and time information of CM-broadcast periods into the recording medium.

It is an object of the present invention to provide a television receiver for discriminating a CM broadcast from a received television broadcast and controlling a volume of the CM broadcast without complicating a configuration of a discriminating process of the CM broadcast. The present invention includes a silence detection means, a scene change detection means, a video audio changing point detection means, a first characteristic amount extraction means, a second characteristic amount extraction means, a comparison determining means and a volume control means. The comparison determining means compares the first characteristic amount which is an audio characteristic amount of a television signal before the time when the video audio changing point is detected, and the second characteristic amount which is an audio characteristic amount of a television signal after the time when the video audio changing point is detected, to determine whether a predetermined condition is satisfied or not. The volume control means controls an output level when outputting audio of the television signal on the basis of a result of the comparison determining means.

A computer implemented method detects scene boundaries in videos by first extracting feature vectors from videos of different genres. The feature vectors are then classified as scene boundaries using a support vector machine. The support vector machine is trained to be independent of the different genres of the videos.

A system and method summarizes multimedia stored in a compressed multimedia file partitioned into a sequence of segments, where the content of the multimedia is, for example, video signals, audio signals, text, and binary data. An associated metadata file includes index information and an importance level for each segment. The importance information is continuous over as closed interval. An importance level threshold is selected in the closed interval, and only segments of the multimedia having a particular importance level greater than the importance level threshold are reproduced. The importance level can also be determined for fixed-length windows of multiple segments, or a sliding window. Furthermore, the importance level can be weighted by a factor, such as the audio volume.

A method detects events in multimedia. Features are extracted from the multimedia. The features are sampled using a sliding window to obtain samples. A context model is constructed for each sample. The context models form a time series. An affinity matrix is determined from the time series models and a commutative distance metric between each pair of context models. A second generalized eigenvector is determined for the affinity matrix, and the samples are then clustered into events according to the second generalized eigenvector.
