Yes. Digital video cameras use image sensors just like digital still cameras. The common sensor technologies are CCD and CMOS, and both have been used in still and video cameras.

The basic idea is the same, but video cameras are often optimized differently. Traditional HD video only needs about 2 megapixels, so a video camera may use fewer pixels than a still camera. Video sensors may also be shaped differently to better match widescreen formats such as 16:9.

One important variation is 3CCD cameras. These use three separate sensors—one each for red, green, and blue. A prism splits the incoming light and sends each color to its own sensor. By contrast, most standard still cameras use a single sensor with a color filter array (typically a Bayer filter), where neighboring pixels record different colors and the full-color image is reconstructed from them.

So: yes, the underlying sensor technology is similar, but the resolution, shape, and color-capture method can differ depending on whether the camera is designed mainly for video or stills.
