An image processing apparatus includes an acquisition unit configured to acquire a bitmap image in which each of contained pixels has an alpha value indicating opacity of this pixel, and a rendering unit configured to render the bitmap image. The rendering unit is configured to, when rendering the bitmap image, refrain from performing alpha blending on a pixel contained in the bitmap image that has a specific alpha value and perform the alpha blending on a pixel contained in the bitmap image that has a different alpha value from the specific alpha value.
