A three-dimensional video imaging device includes an infrared light source unit, an imaging element unit, and a processing unit, the imaging element unit includes a short-range TOF sensor configured to receive a part of infrared light, which is infrared light transmitted at a transmittance of a low value or infrared light reflected at a reflectance of a low value by a prism, a half mirror, another prism, and another half mirror, and a long-range TOF sensor configured to receive a remainder of infrared light, which is infrared light transmitted at a high transmittance value or infrared light reflected at a high reflectance value by the half mirror, and the processing unit calculates first distance data based on an electric charge accumulated in the short-range TOF sensor, and calculates second distance data based on an electric charge accumulated in the long-range TOF sensor.

Three-dimensional video imaging device

A three-dimensional video imaging device includes a light source unit, a three-chip imaging element unit, and a processing unit. The three-chip imaging element unit includes a first prism, a reflection dichroic film, a first imaging element, a second imaging element that is a short-range time-of-flight (TOF) sensor, a third imaging element, a second prism, a half mirror, and a third prism. The processing unit includes an emission control unit, a second imaging element control unit, a third imaging element control unit, a first distance data calculation unit, a second distance data calculation unit, a measurement range determination unit, and a distance data output switching unit.

A first multiplier multiplies a correction value by an adjustment coefficient and generates an adjusted correction value, the correction value being read from the correction value table, and the adjustment coefficient being determined from a zoom magnification and a focus distance. A second multiplier multiplies the adjusted correction value by a cosine of an angle formed between a position of each target pixel and the center of the frame and generates a horizontal correction value that corrects the target pixel in a horizontal direction. A horizontal filter adds all multiplication results obtained by multiplying a plurality of pixels in a left-right direction with each target pixel as a center, by left-right asymmetric coefficients, generates a horizontal high-pass filter component, adds, to each target pixel, a horizontal correction component obtained by multiplying the horizontal high-pass filter component by the horizontal correction value, and corrects each target pixel in the horizontal direction.

A linear matrix circuit generates a second R signal, a second G signal, and a second B signal by performing a matrix operation of a correction coefficient of 3 rows&#xd7;3 columns including first to third correction coefficients, fourth to sixth correction coefficients, and seventh to ninth correction coefficients on a first R signal, a first G signal, and a first B signal. An R coefficient corrector performs correction so that the first correction coefficient to be multiplied by the first R signal is caused to be close to 1 and the second and third correction coefficients to be respectively multiplied by the first G signal and the first B signal are caused to be close to 0, as a first difference value obtained by subtracting the first G signal from the first B signal increases when the first difference value exceeds a first threshold.
