1. A circuit apparatus used for a head-up display of a vehicle, the head-up display displaying a first view object corresponding to a real object in a real space and a second view object in a display area, comprising:
a memory configured to store a warp object image containing a first image of the first view object and a second image of the second view object; and
a warp processing circuit configured to perform warp processing on the warp object image and generate a display image displayed in the display area, wherein
the warp processing circuit is further configured to:
receive tracking information, the tracking information including positions of the real object that is continuously tracked in the real space and is in front of the vehicle;
perform the warp processing on the first and second images of the first and second view objects of the warp object image based on a first warp parameter, the first warp parameter being determined relying on the tracking information to generate a first correction image;
perform the warp processing on the first and second images of the first and second view objects of the warp object image based on a second warp parameter to generate a second correction image, the second warp parameter being determined without relying on the tracking information; and
perform synthesizing processing on the first and second correction images to generate the display image, the display image including the first view object included in the first correction image and the second view object included in the second correction image.
