Video signal processing apparatus, video signal processing method, and video signal processing system
[Object] To contribute to the achievement of a workflow in which an HDR video and an SDR video are compatible with each other. [Solving Means] This video signal processing apparatus includes an HDR video generation unit including a first converter unit that performs OOTF conversion on an HDR video by using an exponentiation function for calculating an exponentiation of 1.2, where 100% is 1, to an input signal level of the HDR video having a range from a point of 0%, where an expression range of an input signal level of an SDR video is 100%, to a change point optionally determined within a range of 100% to 500%, and by using a linear function for multiplying an input signal level of the HDR video having a range higher than the change point by a predetermined coefficient to maintain a change rate of a calculation result in a portion of the change point calculated by using the exponentiation function.
METHOD FOR DRIVING SEMICONDUCTOR DEVICE
The resolution of a low-resolution image is made high and a stereoscopic image is displayed. Resolution is made high by super-resolution processing. In this case, the super-resolution processing is performed after edge enhancement processing is performed. Accordingly, a stereoscopic image with high resolution and high quality can be displayed. Alternatively, after image analysis processing is performed, edge enhancement processing and super-resolution processing are concurrently performed. Accordingly, processing time can be shortened.
Signal Communication Over An Optical Link
Systems and methods for signal communication over an optical link are described. One aspect includes receiving a source CONFIG1 signal from a DP master device and a sink CONFIG1 signal from a sink terminal. The source and sink CONFIG1 signals are analyzed. It is determined whether a signal transmission mode is a DP protocol. For a DP protocol, a pair of source AUX signals is received from the DP master device. A pair of sink AUX signals is received from the sink terminal. Communication resource contention between the source and sink AUX signals is identified. A communication direction of the communication resources is transitioned to give the source AUX signals precedence over the sink AUX signals. The source AUX signals are transferred to the sink terminal via the communication resources. The direction of the communication resources is again transitioned. The sink AUX signals are transferred to the DP master device.
