    摘要: A method for generating coefficients for a set of convolution kernels for use in interpolating pixel values in an image sensor is described. The coefficients are computed by applying a constraint matrix specifying one or more constraints. The method includes generating ideal sensor data representative of a test image in a first color plane, generating sensor data of the test image, generating f data matrices including pixel data from multiple neighborhoods of pixels in the pixel array, and determining the coefficients for f convolution kernels using the ideal sensor data, the f data matrices and by applying one or more constraints. The use of a constraint matrix greatly simplifies the computation of the coefficients and can be applied in image processing to generate a high quality full color image.

    摘要: An imaging system with built-in diagnostics and preferably implemented as an integrated system-on-a-chip (SOC) imaging system. According to one implementation of the present invention, the imaging system can be operated in two operating modes: a normal operating mode and a special diagnostic mode. While running in the diagnostic mode, the imaging system can be configured to detect manufacturing defects. The imaging system can be further configured to compensate for certain types of manufacturing defects. While running in the diagnostic mode, the imaging system (1) identifies pixels that function incorrectly and (2) creates a record of such pixels. In the normal operating mode, the imaging system can use the record to compensate for the missing or incorrect data from these defective pixels during real-time image processing. The present invention simplifies testing of imaging systems and/or image sensors. It also increases manufacturing yield and, therefore, results in lower per-unit manufacturing cost.

    摘要: An anti-color aliasing filter for a digital imaging system is includes a first filtering region that allows any color to pass through. The filter also includes a second filtering region adjacent to the first filtering region to allow a particular color or colors to pass through in order to adjust the color frequency response of the digital imaging system to the remaining colors without affecting the frequency response of the digital imaging system to the colors passing through the second filtering region, such that color aliasing is minimized in the digital imaging system.

    摘要: A system-on-chip imaging system includes an image sensor of a two-dimensional array of pixel elements providing pixel data representing an image of a scene, a data memory for storing pixel codewords whereby at least some of the pixel codewords are indicative of the pixel data, a programmable lookup table for providing LUT codewords as output data, and a processing unit for receiving LUT codewords from the lookup table and generating output image data. In operation, a first pixel codeword stored in the data memory is used to index the lookup table for causing the lookup table to provide a respective LUT codeword to the processing unit. The processing unit operates to perform one or more image processing functions in response to the LUT codeword. The lookup table can be programmed to perform a variety of image processing functions, including defective pixel correction, CDS subtraction, privacy masking and dark signal subtraction.

    摘要: A fixed pattern noise subtraction method in a digital imaging system incorporating a digital image sensor includes: acquiring a reference image of the digital image sensor when the digital image sensor receives no illumination, storing a reference value of an operating parameter associated with the reference image where the reference image is indicative of the fixed pattern noise associated with the digital image sensor, storing a model describing the behavior of the fixed pattern noise as a function of the operating parameter. Then, the method continues with acquiring a first image, measuring a current value of the operating parameter associated with the first image, calculating a noise prediction image by extrapolation of the reference image in accordance with the model and based on the current value and the reference value of the operating parameter, and subtracting the noise prediction image from the first image to generate a final image.

    摘要: An integrated image sensor having a conditioned top silicon oxide layer and/or one or more additional insulating layers/structures to reduce optical and/or electrical noise. The image sensor has an array of one or more pixels, each pixel having a photoelement formed on a substrate and configured to generate an electrical signal in response to incident light, and associated circuitry formed on the substrate and configured to process the electrical signal generated in the photoelement. In one embodiment, a portion of a top insulating layer in the integrated image sensor corresponding to each photoelement has a thickness different from the thickness of a portion of the top insulating layer corresponding to its associated circuitry to inhibit the flow of light between the associated circuitry and the photoelement and/or between the pixel and an adjacent pixel in the array. In another embodiment, the image sensor has one or more insulating structures formed on the substrate and configured to inhibit the flow of electricity between a photoelement and its associated circuitry and/or the pixel and an adjacent pixel in the array. The present invention can reduce optical and/or electrical noise and crosstalk to improve image quality and diminish artifacts in the image sensor's output.
