1. An image processing apparatus comprising: an image input unit that inputs a two-dimensional image signal; a depth information output unit that inputs or generates depth information of image areas constituting the two-dimensional image signal; an image conversion unit that receives the image signal and the depth information from the image input unit and the depth information output unit, and generates and outputs a left eye image and a right eye image for realizing binocular stereoscopic vision; and an image output unit that outputs the left eye image and the right eye image, which are output from the image conversion unit, wherein the image conversion unit extracts a spatial feature value of the input image signal, and performs an image conversion process including an emphasis process applying the feature value and the depth information with respect to the input image signal, thereby generating at least one of the left eye image and the right eye image.
