A filter coefficient calculating unit 81 sets as a filter window a range, which contains plural coordinates including an attention coordinate “p” in an initial alpha map, and uses a pixel value Ip at a coordinate of an original image corresponding to a coordinate “p” in the filter window and a pixel value Iq at a coordinate of the original image corresponding to a coordinate “q” in the filter window to calculate a filter coefficient Kq at the coordinate “q” on a coordinate to coordinate basis in the filter window. That is, a filter coefficient set is created, which consists of filter coefficients calculated on a coordinate to coordinate basis in the filter window. A weighted-average filtering unit 83 uses the filter coefficient set to apply a weighted-average filtering operation on each pixel value in the filter window.

Studio-users prepare guide media video, audio and text data which are made available to mobile users through a media server. A mobile user's mobile replacement-dialogue recording device obtains guide media and allows the user to view the guide media in rehearsal mode. The mobile replacement-dialogue recording device then records the mobile user's dialogue performance while presenting the mobile user with synchronized guide media. The mobile user can review, delete, and rerecord the resulting potential replacement dialogue, as well as create feedback media characterizing the replacement dialogue. Selected replacement dialogue items can be transmitted to the media server. A studio-module can then obtain the selected replacement dialogue items and feedback media from the media server so that they may be used in media-replacement.

Next, the digital camera 1 , which has been placed on a suitable surface (such as on a desk), moves the optical zoom further to the wide-angle side than during the temporary imaging, and performs actual imaging when the self-timer reaches time up. Then, the digital camera 1 identifies the photographic subjects designated by the temporary imaging within the actually captured image, and after determining the left, right, upper, and lower ends of a clipping area such that the identified photographic subjects are included, clips an image of the determined clipping area as a final image.

In a digital picture created by combining an outer zone from a first lens and an inner zone from a second lens, the two zones may be blended together in an intermediate zone created by processing pixels from both the outer and inner zones. The blending may be performed by creating pixels in the intermediate zone that are progressively less influenced by pixels from the first lens and progressively more influenced by pixels from the second lens, as the location of the intermediate pixels transitions from the outer zone to the inner zone. Image registration may be used to achieve the same scale before blending.

Provided is an image matching method of matching at least two images. The image matching method extracts feature points of a reference image and feature points of a target image, changes a feature point, selected from among the feature points of the reference image, to a reference point in the target image, sets a matching candidate region on the basis of the reference point, in the target image, and performs a similarity operation between the selected feature point in the reference image and a plurality of feature points included in the matching candidate region among the feature points of the target image. The image matching method decreases the number of similarity operations performed in the image matching operation, thereby guaranteeing a high-speed operation.

Blur detection with local sharpness map

Номер: US20120162527A1
Автор: Daniel G. Baker
Принадлежит: Tektronix Inc

A single-ended blur detection probe and method with a local sharpness map for analyzing a video image sequence uses two sets of edge filters, one for “fast edges” and the other for “slow edges.” Each set of edge filters includes a horizontal bandpass filter, a vertical bandpass filter and a pair of orthogonal diagonal filters where the frequency response of the fast edge filters overlap the frequency response of the slow edge filters. The video image sequence is input to each filter of each set, and the output absolute values are combined with weighting factors to produce a slow edge weighted sum array and a fast edge weighted sum arra. The respective weighted sum arrays are then decimated to produce a slow edge decimated array and a fast edge decimated array. The ratio of the maximum difference value between the decimated arrays and the maximum value from the fast edge decimated array, weighted by an appropriate factor, produces a localized maximum sharpness value, the log of which produces a dimensionless blur value.

The filter performs at least one infinite impulse response (IIR) filter and at least one finite impulse response (FIR) filter on the image data. A plurality of IIR filters and FIR filters maybe performed to approximate a Gaussian filter. By minimizing the number of passes, the data flow between the processing unit and the storage unit is greatly reduced compared to conventional repeated integral images method thereby improving computation time.

Progressive video reformatting for film-based content

A video formatter reformats progressive video using a film-based video film rate and a display refresh rate to determine a frame OFF period for a progressive video sequence. The video formatter inserts at least one black frame into the progressive video sequence to approximate the frame OFF period. Typically, the film rate is 24 frames per second (industry standard) and, thus, the display refresh rate can be a multiple of the frame rate (e.g., 96 Hz, 120 Hz, 240 Hz, etc.). Progressive video replicates a single frame of a film several times (“a progressive video sequence”) depending on a display's refresh rate. The black frame(s) is/are substituted at the end of this sequence instead of displaying the same image throughout for a single film frame.

In camera implementation of selecting and stitching frames for panoramic imagery

Номер: US20130038680A1
Автор: Ayelet Mashiah
Принадлежит: CSR Technology Inc

A system, method, and computer program product for selecting qualifying frames from an image sequence for use in subsequent stitching into a composite panoramic image are disclosed. Incoming frames from any source may be cropped and downscaled prior to evaluation against qualifying criteria relating to image overlap and local motion. Qualifying images are saved and/or output. The resulting panoramic image generally uses fewer qualifying images and appears smoother and has fewer artifacts than those of the prior art. The qualifying criterion for image overlap is a predetermined overlap margin or percentage between a current image and a previous image from the sequence. The qualifying criterion for image motion includes a maximum amount of local motion, often due to passing objects. The embodiments may process incoming images in real time or from stored sequences. Problems may trigger user warnings.

Auto Exposure Techniques for Variable Lighting Conditions

Принадлежит: Apple Inc.

Systems, methods, and a computer readable medium for performing auto exposure (AE) techniques that are beneficial in variable lighting conditions—and particularly applicable to handheld and/or mobile videoconferencing applications—are disclosed herein. Handheld and/or mobile videoconferencing applications—unlike their fixed camera counterparts—are often exposed to a wide variety of rapidly changing lighting and scene conditions, and thus face a difficult trade-off between adjusting exposure parameter values too frequently or not frequently enough. In personal electronic devices executing such handheld and/or mobile videoconferencing applications, it may be desirable to: use a small, centered, and center-weighted exposure metering region; set a relatively low brightness target value; and adjust the camera's exposure parameter values according to a distance-dependent convergence speed function. The use of such techniques, in conjunction with a relatively large stability region, may also improve the quality of a video encoder's temporal predictions—and thus video quality—in videoconferencing applications. 1. A method comprising:using an image sensor to capture an image representative of a scene;defining an exposure metering region over a desired area of the image;calculating a weighted average value for the exposure metering region;comparing the weighted average value to a predetermined range of acceptable values; andadjusting an exposure parameter for the image sensor based at least in part on the comparison of the weighted average value to the predetermined range of acceptable values.2.
