A generation unit generates complementary information based on an arrangement pattern of pixel values in each of the divided blocks each including 2 by 2 pixels. Further, image data of 1/(2^M) times the resolution is compressed using a first compression method, and image data of 1/(2^N) times the resolution is compressed using a second compression method. The apparatus determines whether to cause a combination of the complementary information and first compressed data to be output, or a combination of the complementary information and second compressed data to be output, based on the data size of each."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image compression apparatus and image compression method","description":"An image compression apparatus performs image compression on high-resolution image data of various resolutions while reducing the circuit size.
