Abstract
Solid-state image-pickup devices and associated drive methods are disclosed that simultaneously provide an image signal and a motion-detection signal. A representative device comprises an array of multiple pixels that produce pixel outputs according to amounts of light received by individual pixels. A vertical-readout line is provided for each column of pixels. A vertical-scanning circuit sequentially outputs signals from the pixels to the vertical-readout lines in horizontal-line units. Differential-processing circuits subtract out dark signals from image signals. Body-motion-detection circuits output a signal based on the difference between the pixel outputs during a current frame and the pixel outputs during a previous frame. A horizontal-scanning circuit sequentially delivers the outputs of the differential-processing circuits and the body-motion-detection circuits onto respective horizontal-readout lines to simultaneously form an image signal and motion-detection signal. The device can provide an electronic shutter function. The motion-detection signal can be either analog or single-bit digital.
