Video signal analysis
In order to detect interlace errors in a video signal, one receives successive digitally coded frames, each frame comprising data for a field of a first type and data for a field of a second type (i.e. a top field and bottom field or vice versa). One then generates for each field of the first type:—a first difference signal (D1 F1) representative of the difference between the field and the second-type field of the previous frame;—a second difference signal (D1 F2) representative of the difference between the field and the second-type field of the same frame; and—a third difference signal (D1 F3) representative of the difference between the field and the second-type field of the following frame. Then, in dependence of the values of said difference signals, a decision signal (wOFlag) is generated indicating an estimated temporal relationship of the field to the second-type field of the same frame. This can be compared with a signal (IDFO) indicating a purported temporal relationship, and an alarm signal (wEFlag) generated in the event of a mismatch.

Technologies and implementations for de-interlacing an interlaced digital video and up-converting a frame rate of a digital video are generally disclosed.
FACILITATING INTERACTION BETWEEN VIDEO RENDERERS AND GRAPHICS DEVICE DRIVERS
Facilitating interaction may be enabled through communication protocols and/or APIs that permit information regarding image processing capabilities of associated graphics hardware to be exchanged between graphics device drivers and video renders. In a first exemplary media implementation, electronically-executable instructions thereof for a video renderer precipitate actions including: issuing a query from a video render towards a graphics device driver, the query requesting information relating to process amplifier (ProcAmp) capabilities; and receiving a response at the video renderer from the graphics device driver, the response including the requested information relating to ProcAmp capabilities. In a second exemplary media implementation, a graphics device driver precipitates actions including: receiving a query at the graphics device driver from a video renderer, the query requesting information relating to ProcAmp capabilities; and sending a response to the video renderer from the graphics device driver, the response including the requested information that relates to ProcAmp capabilities.
IMAGING DEVICE, IMAGING METHOD, AND IMAGING PROGRAM
A discrete-type imaging device includes a camera head and a camera control unit, and video shot by the camera head is transmitted to the camera control unit via a plurality of transmission lines. A temperature sensor measures a temperature of the camera head. A high-temperature control unit determines whether the temperature measured exceeds a predetermined threshold value. A signal processing unit reduces a number of lines used in the plurality of transmission lines when the temperature measured exceeds the predetermined threshold value and transmits video data accordingly.
Method for processing an image sequence having consecutive video images in order to improve the spatial resolution
An image sequence includes consecutive video images each exhibiting at least one image region having a number of pixels, where each pixel includes at least one intensity value. For each image a motion measure value is determined indicative of temporal change of a video content of the image region and varying the intensity values of the pixels of the image region relative to the associated intensity values from video image to video image, a measure for the variation of the intensity values being dependent on the motion measure value determined and the change in the intensity values relative to the associated intensity values being greater the larger the motion represented by the motion measure value.
