摘要:
A monitoring camera can make communication with a client apparatus through an IP network. The monitoring camera includes an image capturing unit that captures an image of an object, a compressing and encoding unit that overlays overlay information on the captured image, and a communication unit that transmits transparency information indicative of whether or not a transparency can be set for each of a first portion and a second portion of the overlay information, which is overlaid by the compressing and encoding unit, to the client apparatus via the IP network.

The display system includes a display system including an image-capturing apparatus including an image-capturing element; an image processing apparatus that performs image processing on the image; and a display apparatus including a display device that displays the image resulting from the image processing. The image processing apparatus includes an image processor that performs the image processing on a predetermined number of line images corresponding to a part of a frame image captured by the image-capturing element, sequentially outputs the image to the display apparatus per the predetermined number of line images, and causes the display apparatus to display the frame image; and a storage device that stores the predetermined number of line images until the frame image is completed. The image processor is configured to perform the image processing including frame unit processing on the predetermined number of line images associated with the frame image to be output.

Transmission of HDR image data is satisfactorily performed between apparatuses.A transmission apparatus (synchronized apparatus) transmits the HDR image data to a reception apparatus (source apparatus) over a transmission path. At that time, the transmission apparatus transmits information on a transmission method for and/or information on gamma correction for the HDR image data to the reception apparatus over the transmission path. The reception apparatus performs processing (decoding processing, gamma correction processing, and the like) on the received HDR image data, based on the information on the transmission method and/or the information on the gamma correction that are received. For example, the transmission apparatus receives from the reception apparatus the pieces of information on the transmission method and/or the gamma correction that the reception apparatus can support, selects the method that the reception apparatus can support, and thus uses the selected method.

A system and method of digital video editing simultaneously displays a plurality of source video windows on a screen, each window showing a digital source video stream. The user may select among the source video windows at any time while they are being shown. The selected digital source video stream appears in a record video window, and continues to run in real-time in both the selected source video window and the record video window. All windows continuously display real-time video streams. The user may continue to make selections among the source video windows as often as desired, and may also select transformations, or special effects, from an on-screen list. The video stream playing in the record window thus forms a digital user-arranged version of selected portions of the source video streams, plus transformations, as selected by the user. The user's selections are stored to permit subsequent playback of the digital user-arranged video stream in a playback window. A single digital audio stream, or selectable multiple digital audio streams, may accompany the source and user-arranged video streams.

Interference in a television receiver due to variations in the frequency of a "920 KHz beat" frequency obtained from the difference in frequency between the 4.5 MHz intercarrier frequency and the 3.58 MHz color subcarrier frequency and detected by the receiver's video detector is reduced by using a color television transmitter having an aural oscillator using a crystal of a smaller size, an "AT" cut and higher frequency followed by frequency division of the oscillator output. The resulting output signal has improved frequency stability and is used as a basis for aural modulation in the television transmitter.
摘要:
A drop-out compensating circuit has an input circuit receiving an angularly modulated input signal, such as, a frequency modulated video signal reproduced from a magnetic tape or other recording media, and supplying such angularly modulated input signal to an output circuit by way of an interposed variable impedance circuit having its impedance controlled in accordance with the amplitude of the angularly modulated input signal, and a complementary signal source is connected to a junction between the variable impedance circuit and the output circuit for effectively replacing the angularly modulated input signal with a complementary signal in the output circuit when a drop-out occurs in the input signal. The complementary signal may be the output of a suitable oscillator, for example, having a frequency corresponding to that of a video signal representing gray in an image or picture reproduced by a cathode ray tube, or the complementary signal may be the delayed replica of an earlier video signal. The variable impedance circuit may be constituted by two diodes connected in parallel and having opposed polarities, or by two transistors of opposite conductivity types which receive the input signal at their base electrodes, and which have their emitter electrodes connected in common to the output circuit while their respective collector electrodes are connected to opposite terminals of a supply voltage source.
