摘要： In a case where it is difficult for a user to determine which of an infra-red light video, a visible light video, and a combined video is desirable for use in monitoring for the reason that the determination result changes depending on the image capturing situation, an image capturing apparatus outputs at least one of the infra-red light image, the visible light image, and the combined image based on a result of detection of an object in the infra-red light image and a result of detection of an object in the visible light image.

摘要： A method of transmitting a video frame over a plurality of communication channels involves selecting a number of communication channels available between the transmitting and the receiving devices; partitioning spatially correlated pixels of the video frame into a number of different partitions equal to the number of selected communication channels; and transmitting the different partitions, where each partition is transmitted on a distinct communication channel among the selected communication channels.Such a method is suitable for use in a communication system, especially a wireless communication system, in which data of a channel can be lost or corrupted. The method can maximize diversity in the transport of the video frame pixels and improve robustness.

摘要： A method and apparatus for image data compression includes detecting a portion of an image signal that uses a disproportionate amount of bandwidth compared to other portions of the image signal. The detected portion of the image signal result in determined components of interest. Relative to certain variance, the method and apparatus normalize the determined components of interest to generate an intermediate form of the components of interest. The intermediate form represents the components of interest reduced in complexity by the certain variance and enables a compressed form of the image signal where the determined components of interest maintain saliency. In one embodiment, the video signal is a sequence of video frames. The step of detecting includes any of: (i) analyzing image gradients across one or more frames where image gradient is a first derivative model and gradient flow is a second derivative, (ii) integrating finite differences of pels temporally or spatially to form a derivative model, (iii) analyzing an illumination field across one or more frames, and (iv) predictive analysis, to determine bandwidth consumption. The determined bandwidth consumption is then used to determine the components of interest.

摘要： A system for reducing bandwidth of video signals. Ordinarily, an NTSC (National Television Standards Committee) video signal has (a) a bandwidth of 6.0 MHz, (b) chrominance and luminance carriers separated by about 3.58 MHz, and (c) an audio carrier located at the upper end of the 6.0 MHz bandwidth. The invention reduces the separation between chrominance and luminance carriers to about 2.15 MHz, and decreases the bandwidth to about 4.0 MHz. In addition, the invention moves the audio carrier outside the 4.0-MHz bandwidth. The invention allows multiple channels, of 4.0 MHz bandwidth each, to be placed adjacent each other in a cable television spectrum, and the audio signals of the channels to be placed together, at the upper end of the spectrum, outside the range allocated to the video information. A larger number of channels is obtained than would otherwise be available, because the upper end of the spectrum is not suitable for carrying video information, but will handle audio information.

摘要： A hybrid television signal of less transmission power or better signal to noise performance is made up by removing low frequency analog components from the video signal, digitizing them and sending them as data in non-active video portions of the transmitted signal. A two step hybridization process, with the first step removing the line averaged value of the video components of the video signal and the second step removing the remainder of the video components under 200 KHz, is described. Temporal filtering, signal pre-emphasis, compression, time dispersion and double sideband suppressed carrier modulation about a centered carrier are disclosed for reducing peak signal amplitudes and for minimizing co-channel interference to and from NTSC signals. Time dispersion is done horizontally, vertically or both to reduce the peak signal amplitudes. Time dispersion in conjunction with low frequency removal and temporal filtering is preferred. Time dispersing lower frequencies more than higher frequencies contributes to an optimized video display. The hybrid signal system is uniquely adapted to a high definition television signal in a limited frequency channel with an NTSC signal.

摘要： A communication device transmits a video to a reception-side device connected via N communication lines. N is an integer of 2 or more. The communication device includes a controller. The controller spatially separates an image of one frame into N separate images. Then, the controller transmits the N separate images to the reception-side device in parallel via the N communication lines, respectively.

摘要： Various embodiments of the disclosure relate to a video transmittance device and method capable of robust response to network bandwidth changes by changing the resolution or frame rate of a video based on a dual-bandwidth threshold which is a reference value for determining whether to change the resolution or frame rate of a video signal and a network bandwidth prediction value determined based on predetermined control information received from a video reception device. The video transmission device may include: receiving a video signal, setting a dual-bandwidth threshold which is a reference value for determining whether to change a resolution or a frame rate of the video signal, determining a network bandwidth prediction value based on specified control information received from a video reception device, determining whether to change the resolution or frame rate of the video based on the network bandwidth prediction value and the dual-bandwidth threshold, updating frame sequence information based on the resolution or frame rate being changed, setting an encoding parameter based on the changed resolution or frame rate, encoding the video signal based on the set encoding parameter, and transmitting the encoded video signal to the video reception device.
