Disclosed is a camera including: an image-taking device; a shutter unit having a first shutter member that travels from a position where a shutter opening is closed to a position which is retreated from the opening, and a second shutter member that travels from the position which is retreated from the shutter opening to the position where the opening is closed; a lighting unit that lights a subject; and a control circuit that controls the shutter unit, the lighting unit and the image-taking devi...

A method of obtaining an image uses a broad dynamic range image sensor that includes a photosensitive cell formed of pixels. Each pixel includes a element, a first initialization transistor series connected to the element, storage means coupled to the element, a third initialization transistor series connected to a capacitor, and fourth and fifth series connected transistors, wherein one control terminal of the fourth transistor is connected to the capacitor. The method comprises initializing th...

An imaging device comprises a photoelectric conversion element; first, second, and third capacitors; first, second, third, and fourth charge transfer elements; a reset element; and an amplifier element. The photoelectric conversion element generates an electrical charge according to the amount of received light. The first and second capacitors receive and store the electrical charge. The electrostatic capacity of the second capacitor is lower than that of the first capacitor. The first and secon...

An imaging architecture is provided employing CMOS imaging sensors. The imaging architecture utilizes time domain sampling techniques to extract image data from a photodiode (PD) pixel array. The CMOS imaging architecture associates time index values with firing of CMOS imaging sensors in response to a capture of an image. The time index values correspond to the brightness of the illumination received by the CMOS imaging sensor. The time index value associated with the firing of the CMOS imaging...

Disclosed is a solid-state imaging device comprising pickup circuit formed by the arrangement of a unit cell in two dimensions, a plurality of reading lines provided in a horizontal direction corresponding to each pixel row in the pickup region to transmit the reading drive signal .phi.READi for driving each reading circuit of the unit cell of respectively corresponding pixel row, a vertical drive selection circuit configured to drive the reading circuit by selectively supplying the reading driv...
