摘要： An image sensor that includes a first imaging array and a FPGA processor that processes images captured by the imaging array to provide information about the scene projected on the first imaging array is disclosed. The FPGA processor is connected to the first imaging array and includes an interface for receiving images from the first imaging array and an interface to an image storage memory that stores a plurality of images. The FPGA implements a plurality of image processing functions in the gates of the FPGA. The image processing functions processing one of the images stored in the image storage memory to extract a quantity related to the one of the images. The FPGA also includes an I/O interface used by the FPGA to output the quantity to a device external to the image sensor.

摘要： An x-ray imaging system and a method for retrofitting existing x-ray generators to allow those generators to be controlled by a digital x-ray imaging system are disclosed. The x-ray imaging system includes an imaging array and an image controller. The imaging array is configured to be positioned within a patient's mouth, the imaging array acquiring an image of the patient's teeth when the patient's head is illuminated with x-rays. The imaging array includes an x-ray dosimeter that provides an x-ray exposure signal indicative of an x-ray exposure received by the imaging array. The image controller is coupled to the imaging array and receives the x-ray exposure signal, the image controller includes a first wireless link that controls an x-ray generator by initiating a pre-programmed x-ray exposure. The wireless controllable switch can be used to replace an existing manually controlled switch in an existing x-ray generator.

摘要： A column readout amplifier and imaging array using the same method are disclosed. The column readout amplifier includes a signal amplifier having an amplifier signal output, a first filter capacitor, a buffer amplifier having a buffer amplifier input and a buffer amplifier output, and a switching network. The switching network connects the amplifier signal output to the buffer amplifier input and the buffer amplifier output to the first filter capacitor during a first time period, and connects the amplifier signal output directly to the first filter capacitor during a second time period. The time periods can be of fixed duration or determined by the difference in potential between the input and output of the buffer amplifier. The column readout amplifier can be used in an imaging array to readout columns of pixels.
