An image capturing apparatus realizes a precise focus assist function without losing edge information of a multi-pixel video image. The image capturing apparatus includes an image sensor arranged in a Bayer array, a circuit for converting resolution of the video signal obtained by the image sensor, a circuit for extracting high frequency components of each color pixel data of the video signal, a selection circuit for selecting the high frequency components of four pixels in a unit of the Bayer array and for outputting the component of the greatest amplitude as peaking information, and a superimposition circuit for superimposing the peaking information on the video signal of the resolution or substituting the video signal with the peaking information.
