It is an object of the present invention to provide a video signal processing apparatus that can be reduced in production cost, and perform an electronic zooming function. In the video signal processing apparatus, a noise reduction of and a gain adjustment of the video signal from the imaging element 12 is performed by the analog preprocessing means 13. The video signal from the analog preprocessing means 13 is then converted into a digital signal by the A/D converter 14 in synchronization with the horizontal sync signal and its clock signal. The luminance and color difference signals are produced from the digital signal by the Y/C signal processing means 15, and delayed by the line delay means 16 on the basis of the period of the horizontal sync signal. The interpolating means 18 performs the vertical pixel interpolation process, on the basis of the vertical interpolation coefficient outputted by the zooming control means 17, by using the output signal of the Y/C signal processing means 15 and the output signal of the line delay means 16, and performs the horizontal pixel interpolation process, on the basis of the horizontal interpolation coefficient outputted by the zooming control means 17, by using pixels horizontally-adjacent to each other.
