by reading contiguous pixels from selected rows or columns of the array, e.g. interlaced scanning

Full Title

Circuitry of solid-state image sensors [SSIS]; Control thereof > Extracting pixel data from image sensors by controlling scanning circuits, e.g. by modifying the number of pixels sampled or to be sampled > by partially reading an SSIS array > by reading contiguous pixels from selected rows or columns of the array, e.g. interlaced scanning
