    Abstract: A method of operating an image sensing device includes applying control voltages to a pixel array in accordance with a test mode and performing an analog-to-digital conversion of a column line voltage to obtain one or more digital codes. The one or more digital codes are evaluated to detect an operating error associated with the column line and/or corresponding analog to digital converter. In response to an operating error, pixel values may be replaced or averaged with nearby pixel outputs not affected by the operating error.
