The column readout circuits may include test data injection circuitry and converter circuitry coupled to column memory via switching circuits. The injection circuitry may enable the switching circuits so that pixel data is stored on the column memory as rows of an image frame. The injection circuitry may disable the switching circuits and may inject test bits onto the column memory while the switching circuits are disabled. The column memory may store the test bits as one or more rows of the image frame interspersed among rows of the pixel data. Verification circuitry coupled to the column readout circuits may process the test data bits in the image frame to verify proper functionality of some or all of the imaging system without disrupting normal imaging operations by the imaging system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging systems having column readout circuitry with test data injection capabilities","description":"An imaging system may include an array of image pixels and column readout circuits coupled to each column.
