1. A circuit apparatus used for a head-up display that displays 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 an image of the first view object and an 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 configured to perform:
the warp processing on the image of the first view object of the warp object image based on a first warp parameter for both vibration correction and distortion correction, wherein the vibration correction is configured to correct a display position difference of the first view object relative to the real object, and the distortion correction is configured to correct distortion due to at least one of curvature of the display area and an optical system; and
the warp processing on the image of the second view object of the warp object image based on a second warp parameter for the distortion correction.
