    摘要: A shutter and aperture device of a miniature digital camera module is coupled to a moveable lens group and is controlled by a horological type stepper motor from a fixed position from outside the moveable lens group. The coupling element between the stepper motor and the shutter device is a mechanical drive apparatus that allows movement of the shutter device along an optical axis before, during and after adjustment of the shutter setting by the stepper motor. The stepper motor is driven with CMOS I/O allowing integration of all control circuitry, image processing circuitry and a pixel photo imager array into a system-on-chip integrated circuit chip.

    摘要: An apparatus and method for automatically focusing a miniature digital camera module (MUT) is described. A MUT is loaded onto a test fixture and aligned with an optics system of a test handler. Focus targets contained within two target wheels are positioned over an optical centerline above the digital camera module using stepper motors. A field lens is positioned to focus an image of the targets onto the lens opening of the MUT. The image can be of a single target or a combination of targets contained on the target wheels at various optical distances from the MUT. A focusing unit adjusts the lens cap of the MUT for a best focus setting and after the MUT has been tested the best focus setting if physically fixed by permanently connecting the lens cap to the body of the MUT.

    摘要: An active pixel sensor circuit comprising a photodiode, a storage node, and a transfer gate between the photodiode and storage node, where the potential barrier between the photodiode and the storage region is maintained during charge accumulation, thereby preventing charge tunneling between the photodiode and the storage region. This is achieved by electrically connecting the transfer gate, which controls charge transfer between the photodiode and the storage region, to the storage region. Connecting the transfer gate to the storage region maintains the potential barrier between the photodiode and the storage region at a threshold voltage during the charge integration period which prevents charge tunneling between the photodiode and the storage node. The threshold voltage is determined by the implant levels used to form the active pixel sensor and can be optimized by using optimum implant levels. This prevention of charge tunneling between the photodiode and the storage node eliminates image lag.

    摘要: A pixel circuit with a dual gate PMOS is formed by forming two P+ regions in an N− well. The N− well is in a P+ type substrate. The two P+ regions form the source and drain of a PMOS transistor. The PMOS transistors formed within the N− well will not affect the collection of the photo-generated charge as long as the source and drain potentials of the PMOS transistors are set at a lower potential than the N− well potential so that they remain reverse biased with respect to the N− well. One of the P+ regions used to form the source and drain regions can be used to reset the pixel after it has been read in preparation for the next cycle of accumulating photo-generated charge. The N− well forms a second gate for the dual gate PMOS transistor since the potential of the N− well 12 affects the conductivity of the channel of the PMOS transistor. The addition of two NMOS transistors enables the readout signal to be stored at the gate of one of the NMOS transistors thereby making a snapshot imager possible. The circuit can be expanded to form two PMOS transistors sharing a common drain in the N− well.

    摘要: A method and a system for an automatic white balancing of color images being exposed to different illuminants have been achieved. The color information from the sensor color channels is measured and averaged over all pixels belonging to each of the colors of the color array used. The result is equivalent to what color a 1-pixel camera would see if pointed to the same scene. From this “statistical pixel” the ratios of the colors involved are calculated. Pictures taken in different illuminants as e.g. daylight, fluorescent light or incandescent light can then be separated due to their location in different categories in a space defined by said ratios of the colors involved. Each category has predefined white balance factors, which are applied to the image now.

    摘要: A horological motor of the Lavet motor concept is used to form an actuator to control movement of a lens system to reduce power consumption in digital camera units used in various electronic equipment, e.g. PDA's, mobile phones, digital still cameras and camcorders, and as a result increase battery life. The coils of the horological motor are driven with CMOS I/O signals eliminating the need for high current motor drivers and allowing the integration of all picture capture functions, including the light sensitive pixel array, into a single chip to form a system on chip implementation. A plurality of actuators is used to control a lens system comprising auto focus, zoom and shutter and iris functions. A gear transmission system is used to allow the motor of the actuator to move in micro step, which allows calibration of the motor against mechanical barriers.
