The image processing unit performs arithmetic operation on an image signal corresponding to pixels on a predetermined number of vertical lines using correction values for increasing a luminance in accordance with the position of each vertical line so that a lack of transmittance for a rising period or falling period of shutters of liquid crystal shutter glasses is compensated for, thus generating luminance signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"3D image control apparatus and method","description":"A 3D image control apparatus is provided which prevents unevenness of luminance in an observed image on a screen caused in a 3D image viewing system including an impulse type display device and liquid","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531508","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
