Abstract:
1. A pixel data generating device for generating a plurality of pixel data as pixel data in an XY rectangular coordinate system, the plurality of pixel data including: first pixel data generated on a first sweep line, according to a distance from a transmitting source, based on an echo signal of a detection signal that is discharged from the transmitting source toward a first direction; and second pixel data generated on a second sweep line, according to a distance from the transmitting source, based on an echo signal of a detection signal that is discharged from the transmitting source toward a second direction different from the first direction; the pixel data generating device, comprising: a pixel data converting module for converting the first pixel data and the second pixel data into pixel data in the XY rectangular coordinate system, respectively; an interpolation pixel data generating module for generating pixel data of an interpolation target pixel that is located between a first pixel as an observing pixel on an interpolation axis parallel to the X-axis or the Y-axis of the XY rectangular coordinate system and a second pixel as a corresponding pixel on the same interpolation axis, based on the pixel data on the first sweep line and the pixel data on the second sweep line.
