Even when mixing video data whose video formats are different, appropriate mix processing can be performed. Output video data is obtained by performing mix processing such as dissolve and wipe on first video data and second video data. Before performing the mix processing, a format of the first video data and the second video data is made the same as a video format handled by the mixing unit. Further, after performing the mix processing, a format of the output video data is made the same as an output video format.

Video data processing device and video data processing method

A signal switching apparatus includes multiple video image processing units, a controller configured to control operation of the video image processing units, and a graphical user interface (GUI) configured to receive input of a selection between an HD mode and a quartering-4K mode which are operation modes of the video image processing units. The controller controls the video image processing units so that the video image processing units operate in the HD mode or quartering-4K mode, on the basis of a selection inputted to the GUI.

Signal switching apparatus and method for controlling operation thereof

There is provided an image processing apparatus including: a plurality of signal processing circuits that compose video signals; and a communication path that connects the plurality of signal processing circuits, wherein any one of the plurality of signal processing circuits composes a video signal obtained by composition by the signal processing circuit, and a video signal obtained by composition by another signal processing circuit supplied from the another signal processing circuit via the communication path.

Image processing apparatus, image processing method, and image processing system

In an image processing apparatus, an image processor includes: a matrix switcher, wherein intersecting input and output lines are connected by crosspoint switches; a signal processing block connected to output lines on the upstream side, and input lines on the downstream side by reentry paths; and an output block connected to output lines on the upstream side. An external reentry settings unit sets a first and second port of the matrix switcher as external reentry output ports, the first port being a matrix switcher output port, and the second port being a matrix switcher input port. A reentry stage information generator generates reentry stage information, which indicates the stage of the internal signal processing path where a special function unit is logically positioned, and wherein the special function unit corresponds to the external reentry output ports of the signal processing block and the output block.

It is an object of the present invention to provide a color conversion apparatus in which an output result of a color converting circuit at the succeeding stage for color-converting a specific color can be prevented from being affected by an output result of a color converting circuit at the preceding stage for color-converting a whole image. Since a first color converting circuit ( ) color-converts a whole image of image data in a first color-conversion fashion. A second color converting circuit ( ) color-converts only the area of such color in a second color-conversion fashion by adding a correction signal which results from multiplying a key signal ( ) indicative of an area of specific color to image data in which the whole image is color-converted in a first color-conversion fashion and a key signal generating circuit ( ) generates the key signal ( ) from the image data supplied to the first color converting circuit the output result of the second color converting circuit ( ) at the succeeding stage for color-converting the specific color can be prevented from being affected by the output result from the first color converting circuit ( ) at the succeeding stage for color-converting the whole image.

In a key signal waveform shaping apparatus which includes an adder 1 for supplying a key source signal KS with a gain of a predetermined slice level, a multiplier 2 for extending a signal offset by the adder 1 by multiplication of a gain, and a first limiter circuit 3 for converting the signal extended by the multiplier 2 by cutting an upper limit value and lower limit value of the extended signal. A limit value generating circuit generates an upper limit value and lower limit value from the signal offset by the adder 1. The key signal K is obtained by further limiting the output of the first limiter circuit 3 by the upper limit value and the lower limit value. The present invention provides a key signal waveform shaping apparatus in which an error of an edge position of a key signal can be removed and in which the quality of a synthesized picture can be improved.
