Summary:The present disclosure illustrates an optical navigation apparatus with blurs image compensatory function and a compensation circuit thereof. The optical navigation apparatus comprises a light source, an image sensing circuit and a compensation circuit. The light source is configured to illuminate a work surface. The image sensing circuit captures a first image from the work surface according to the light source. The compensation circuit is configured to provide a point spread function of the light source, and transform the first image and the point spread function into a first conversion result and a second conversion result, respectively. After the first conversion result and a reciprocal of the second conversion result multiplies, a second image generated from the compensation circuit.
