Signal transmitting device and signal transmitting method

A signal transmitting device comprising:

• a multiplexing section configured to, in a case of an image pickup element of a double density Bayer structure as a pixel arrangement in which pixel density of a Bayer structure is doubled and pixels are arranged obliquely at 45° with respect to said Bayer structure, said double density Bayer structure being a structure such that a first line read in order of a B pixel, a G pixel, an R pixel, and a G pixel and a second line read in order of an R pixel, a G pixel, a B pixel, and a G pixel are arranged alternately in a horizontal direction, generate a B/R ch by alternately multiplexing image signals read from B pixels and R pixels among image signals read and input in units of a predetermined number of samples in each of the first line and the second line from said image pickup element in an active region corresponding to a C ch in High Definition Serial Digital Interface (HD-SDI) together with start code of one of SAV and EAV, and generate a G ch by multiplexing, in order, image signals read from G pixels in an active region corresponding to a Y ch in HD-SDI together with said start code;
• and
• an 8B/10B encoder configured to output serial digital data converted by 8B/10B-encoding the active regions on the B/R ch and the G ch having data structures corresponding to said HD-SDI and an auxiliary data region including SAV, EAV, LN, and CRCC.
