There is provided a signal input unit to prevent or reduce an increase in memory hardware on a transmitter or a receiver of a serial digital signal, and to decrease the load on a CPU. The signal input unit receives as an input a video signal and a digital signal for transmission, the digital signal for transmission including a data packet with metadata associated with the video signal. The data writing unit extracts predetermined metadata from the digital signal for transmission on the basis of metadata-specifying information and writes the extracted metadata in an accumulating register. For example, the metadata-specifying information includes header information of the data packet with the predetermined metadata. For example, the header information includes classification information indicating a classification for the predetermined metadata and auxiliary information of the predetermined meta-information.

Signal processing apparatus and signal processing method

To enable HDR video signals of a plurality of signal interfaces to be satisfactorily handled. [Solution] A processing unit processes a linear high dynamic range video signal and obtains a high dynamic range video signal that has undergone a grayscale compression process. The processing unit is able to perform grayscale compression processes of a plurality of signal interfaces. For example, when a grayscale compression process of another signal interface other than a reference signal interface is performed, the processing unit further performs a process of adding characteristics of system gamma of the reference signal interface and a process of cancelling out characteristics of system gamma of the other signal interface.

To enable routing control to be easily performed in a video system. Signal output equipment generates and outputs a digital signal for transmission in which the digital signal includes a video signal and a predetermined number of identification information groups related to the video signal. A routing unit outputs an inputted digital signal for transmission to a predetermined signal output unit on the basis of at least any identification information included in the predetermined number of identification information groups.

Signal processing device and signal processing method

Imaging-related information such as information regarding the position or orientation of a camera is output in an appropriate manner. A control device according to the present technology includes: a determination unit that determines a usage mode of an imaging device; and a control unit that performs output control of imaging-related information related to the imaging device on the basis of the usage mode determined by the determination unit. Performing the output control of the imaging-related information on the basis of the usage mode of the imaging device makes it possible to perform control so as not to output unnecessary information according to the usage mode of the camera. For example, in a case of a fixed camera that does not move, the imaging-related information as position information of the camera is not output, and in a case of a handy camera that is assumed to move, the imaging-related information as the position information of the camera is output.

To satisfactorily detect an edge detection signal of a high frequency band from a captured image signal at all times. A filtering unit extracts an edge detection signal of a high frequency band from an image signal obtained from imaging, and a band control unit controls the high frequency band on the basis of lens information. For example, the filtering unit includes a first high-pass filter with a first cutoff frequency, a second high-pass filter with a second cutoff frequency that is lower than the first cutoff frequency, and an &#x3b1; blending unit that performs &#x3b1; blending on output of the first high-pass filter and output of the second high-pass filter. Even if the frequency of the edge detection signal included in the captured image signal varies due to a change in a zoom position, a lens model number, an F value or the like, the edge detection signal can be satisfactorily detected at all times.

Edge detection signal processing

It is made such that a user can easily and appropriately evaluate luminance of an HDR video signal. A luminance evaluation value is obtained by processing the HDR video signal. The luminance evaluation value is displayed on a display unit. For example, the HDR video signal is a linear HDR video signal and/or the HDR video signal obtained by performing gradation compression on the linear HDR video signal with a log curve characteristic. For example, the luminance evaluation value includes an average picture level, a high light share ratio, a high light average picture level, a product value of the high light share ratio and the high light average picture level and the like.
