摘要： An image sensor includes multiple photoactive pixels and multiple dark reference pixels arranged in rows and columns to form a pixel array. A dark signal is read out of one or more dark reference pixels in each column and used to determine a column offset for one or more columns in the pixel array. Each time an image or frame of an image is read out, the column offset for the one or more columns is updated using dark signals read out from a given number of dark reference pixels. The column offset for the one or more columns is scaled when a gain level is changed for a captured image.

摘要： An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. A timing generator outputs a column address sequence that is received by a column decoder that is electrically connected to each output circuit. The timing generator suspends the output of the column address sequence during a sample operation and resumes the output of the column address sequence at the end of the sample operation.

摘要： An image sensor includes multiple photoactive pixels and multiple dark reference pixels arranged in rows and columns to form a pixel array. A dark signal is read out of one or more dark reference pixels in each column and used to determine a column offset for one or more columns in the pixel array. An offset window is used for each column in the pixel array to define an acceptable maximum dark signal and an acceptable minimum dark signal for each column. The dark signals from each column are analyzed to determine if there are any dark signals outside the offset window. If any of the dark signals are outside the offset window, the dark signal or signals can be compensated for or discarded.

摘要： A printer apparatus and method for processing image data includes a disk storage module operable to receive, store and output compressed image data, a semiconductor RAM memory device, a data decompressor operates on the compressed image data output by the RAM memory device and a controller that determines if the disk storage module is ready to operate in a write mode or in a read mode to output compressed image data from the disk storage module for transfer to the RAM memory device. The controller also determines if the disk storage module is ready to operate in both modes, and the controller is operative to provide a preference for operation of the read mode and controls the disk storage module so that compressed image data is output from the disk storage module and written into the RAM memory device.

摘要： A printer apparatus includes a marking engine subsystem that records information on an image recording member. An image storage subsystem buffers image data for output to the marking engine subsystem. The image storage subsystem includes an input for receiving rasterized image data. A data compressor operates on the rasterized image data to compress the rasterized image data to form compressed image data. A disk storage module receives, stores and outputs the compressed image data to a semiconductor RAM memory device that stores at least one page of the compressed data. A data decompressor operates on the compressed data output by the RAM memory device and decompresses the compressed data to rasterized data for output to the marking engine subsystem. A RAM controller controls the RAM memory device for outputting the compressed data from the RAM memory device to the decompressor. The disk storage module outputs compressed data to the RAM memory device at a data rate greater than the maximum sustainable data recording rate of the marking engine subsystem.

摘要： An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. An analog front end (AFE) circuit processes pixel data output from the output circuits and an AFE clock controller transmits an AFE clocking signal to the AFE circuit to effect processing of the pixel data. A timing generator outputs a column address sequence that is received by a column decoder. During one or more sample operations the AFE clock controller suspends the output of the AFE clocking signal and the timing generator suspends the output of the column address sequence during the sample operation. The output of the AFE clocking signal and the column address sequence resume at the end of the sample operation.

摘要： An image sensor includes multiple photoactive pixels and multiple dark reference pixels typically arranged in rows and columns to form a pixel array. A dark signal is read out from a given number of dark reference pixels in each column at a first gain level. An initial column offset correction is determined for one or more columns in the pixel array using respective dark signals read out at the first gain level. The initial column offset corrections are repeatedly scaled in response to each detected change to a different gain level. The column offset corrections can be scaled based on an amount of change between each respective different gain level and the first gain level.
