An image-pickup apparatus for capturing an object includes a distance calculating unit for measuring a phase difference (time difference) from the emission of light from a light emitting unit to the reception of reflected light by a light receiving unit for each unit composed of a predetermined number of adjacent pixels of the object to calculate a distance from the image-pickup apparatus to each corresponding pixel unit of the object, and an image processing unit for corresponding the distance calculated in units of the predetermined number of pixels to the image captured by the light receiving unit. The image processing unit supplies a display unit with only pixels corresponding to a predetermined range in the image generated by the distance calculating unit to display the pixels in units of the predetermined number of pixels on the display unit.
