Abstract
A focus indicator for a TV camera includes a first image sensor and a video processor which convert an object image to a first video signal, an optical system for exit pupil dividing part of the object image to prepare a split image, and a second image sensor for converting the split image to a second video signal. A composing circuit generates a composite video signal from the first and second video signals in such a way as to include the split image component, and a viewfinder displays an image including the split image. A user of the TV camera thus can perform focusing by observing the split image in the viewfinder.
