An image pickup element converts an optical image of an object into an electrical image signal. The image signal is applied to a signal processing circuit and separated into a luminance signal and color signals. The separated color signals or the R and B signals are amplified by gain control circuits under the control of the correction signals supplied by a correction signal computing part, and then applied to a color-difference signal forming circuit which in turn produces color-difference signals (R-Y) and (B-Y). An encoder circuit generates a television signal in the standard form from the above color-difference signals and the luminance signal. In this processing, the white balance is adjusted according to a white balance control signal generated on the basis of information about a state of illuminance onto an object picked up last time and stored in a data storing part."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup apparatus including automatic white balance control capability","description":"An image pickup apparatus such as a video camera has the capability of automatic white balance control whereby the white balance is quickly adjusted for any object even just after an operator has turn","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520092","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.
