Image Sensors Including Pixel Arrays

摘要

An image sensor capable of preventing generation of a line-type defect is disclosed. The image sensor includes a row driver, a pixel array, an analog signal processor, a data mapping buffer and a row data buffer. The pixel array has a layout configuration having a nonlinear pattern for a row path and a column path, receives optical signals and converts the optical signals into electric signals, and outputs the electric signals as image signals in response to the pixel control signals. The analog signal processor performs analog-to-digital conversion on the image signals to generate first signals. The data mapping buffer compensates position errors caused by the layout configuration of the zigzag pattern for the first signals to generate a second signals.

1. An image sensor, comprising:
a row driver configured to generate pixel control signals; a pixel array including a plurality of rows and a plurality of columns each having pixels, wherein the pixels are connected by metal lines in a layout configuration having a nonlinear pattern for a row path and a column path, configured to receive optical signals and convert the optical signals into electric signals, and configured to output the electric signals as image signals in response to the pixel control signals; an analog signal processor configured to sample the image signals, and perform analog-to-digital conversion on the sampled image signals to generate first signals; a data mapping buffer configured to compensate position errors caused by the layout configuration of the nonlinear pattern for the first signals to generate second signals; and a row data buffer configured to select one of a signal of odd-numbered row and a signal of even-numbered row of the second signals.
