A video transmitting/receiving device includes: a receiving unit which receives video content; a converting unit which performs predetermined conversion on a video signal included in the video content; an information adding unit which adds a complement signal to the video signal converted by the converting unit; an input/output unit which inputs information of an external device and outputs the video signal; and a control unit, and the control unit performs control to select and output one of the video signal before performing the conversion by the converting unit, the video signal which has been converted by the converting unit, and the video signal to which the complement signal has been added by the information adding unit, in accordance with device information of the external device serving as an output destination, which is obtained by the input/output unit.

Video transmitting/receiving device and video display device

An imaging device is provided with a lens distortion correction function that requires less circuit scale and does not degrade image resolution. The imaging device having the lens distortion correction function is provided which includes a same-color interpolation unit that generates a lens distortion-corrected interpolation signal by using a same-color pixel in an image signal from an imaging element, a luminance signal generation unit that generates a luminance signal from the image signal from the imaging element, a first luminance signal generation unit and a second luminance signal generation unit that use the luminance signal generated by the luminance signal generation unit to generate a lens distortion-corrected interpolation signal, a lens distortion characteristics table data unit that holds information of coordinates after lens distortion characteristics correction in a memory, a coordinate/interpolation coefficient setting unit that individually generates interpolation coefficients for correcting lens distortion for each of the same-color interpolation unit, the first luminance interpolation unit, and the second luminance interpolation unit on the basis of information from the lens distortion characteristics table data unit, and a correction unit that outputs a lens distortion-corrected interpolation signal by correcting the signal from the same-color interpolation unit on the basis of a ratio between the interpolation signal generated by the first luminance interpolation unit and the interpolation signal generated by the second luminance interpolation unit.

Imaging device

An image signal processing apparatus, which includes a first area input-output characteristics control unit, which controls change of input-output characteristics for every arbitrary area associated with a value of an input luminance signal. The image signal processing apparatus also includes a second area input-output characteristics control unit, which controls change of input-output characteristics for every arbitrary area associated with an output of the first area input-output characteristics control unit, and a chrominance input-output characteristics control unit which controls the change of the input-output characteristics of an input chrominance signal by utilizing the output of the first area input-output characteristics control unit and the output of the second area input-output characteristics control unit.
