Abstract
A television camera which carries out color separation by use of vertical correlation in a picture, comprises a pickup element for scanning a target, a color separating stripe filter, and an optical filter for separating a single incident light beam in a direction which is the same as the scanning direction of the pickup element and a direction perpendicular to the scanning direction, by acting on the single incident light beam in two dimensions. The optical filter comprises a first double refraction transparent plate for separating a light beam in a direction which coincides with the scanning direction of the pickup element, a second double refraction transparent plate for separating a light beam in a direction which is rotated by 45.degree. with respect to the scanning direction, and a third double refraction transparent plate for separating a light beam in a direction perpendicular to the scanning direction. The first, second, and third double refraction transparent plates are stacked.
