A photoelectric conversion device suitable for use as an element of a photodetector array includes a photodiode for generating a first signal charge in response to incident light, an output unit including a JFET, and at least one transistor having an electrode that generates a second signal charge in response to incident light. The first and second signal charges may be output separately or combined.

An image sensor array may have one or more pixels with such light monitoring capability. The output signal for monitoring the light may be output over a reset drain interconnection, directly from the monitoring pixel or through other pixels via inter-pixel MOSFETS. Exposure time may be controlled, by timing a shutter or a strobe or the like, based on the monitored accumulation of signal charge during exposure. Microlenses may be provided on-chip to increase the effective aperture ratio of the array. The microlenses are designed to avoid interfering with the incident light used for monitoring. Resulting pixel-to-pixel variations in effective aperture ratio, if any, may be electronically compensated.

TOF system shutter time needed to acquire image data in a time-of-flight (TOF) system that acquires consecutive images is reduced, thus decreasing the time in which relative motion can occur. In one embodiment, pixel detectors are clocked with multi-phase signals and integration of the four signals occurs simultaneously to yield four phase measurements from four pixel detectors within a single shutter time unit. In another embodiment, phase measurement time is reduced by a factor (1 / k) by providing super pixels whose collection region is increased by a factor “k” relative to a normal pixel detector. Each super pixel is coupled to k storage units and four-phase sequential signals. Alternatively, each pixel detector can have k collector regions, k storage units, and share common clock circuitry that generates four-phase signals. Various embodiments can reduce the mal-effects of clock signal transients upon signals, and can be dynamically reconfigured as required.
