摘要： A solid state imaging system has at least one CMOS imager with first and second series of pixels in which the pixels of one series are offset, i.e., staggered, in respect to the pixels of the other series. Multiple imagers can be arrayed end to end, with jumper wires connecting the pixel output conductors or each so that the pixels feed into a common output amplifier for each series, to minimize chip to chip offset voltages. The pixels may be diagonally offset from one another, and a color imager can be constructed in which color ribbon filters are arranged diagonally across the imaging area. This arrangment minimizes color cross talk.

摘要： Improving the dynamic range of captured images is disclosed by using sub-pixel arrays to capture light at different exposures and generate color pixel outputs for an image in a single frame. Each sub-pixel array can include multiple sub-pixels. The sub-pixels that make up a sub-pixel array can include red (R) sub-pixels, green (G) sub-pixels, blue (B) sub-pixels, and in some embodiments, clear sub-pixels. Those sub-pixel arrays having clear sub-pixels effectively have a higher exposure level and can capture low-light scenes (for dark areas) better than those sub-pixel arrays without clear sub-pixels. Each sub-pixel array can produce a color pixel output that is a combination of the outputs of the sub-pixels in the sub-pixel array. Each sub-pixel in a sub-pixel array can have the same exposure time, or in some embodiments, individual sub-pixels within a sub-pixel array can have different exposure times to improve the overall dynamic range even more.

The different pixels under the same microlens can have different integration times, to increase the dynamic range of the imager(s).

摘要： A solid state imager converts analog pixel values to digital form on an arrayed per-column basis. A counter is coupled to an N-bit DAC to produce an analog ramp that varies corresponding to the contents of the counter. A ripple counter is associated with each respective column. A clock or a source of counts at a predetermined sequence supplies clock signals or counts to the counter elements. Column comparators gate the counter elements when the analog ramp equals the pixel value. The counter contents feed a video output bus to produce the digital video signal. Additional black-level readout counters elements can create and store a black level digital value that is subtracted from the pixel value to reduce fixed pattern noise. The counters may employ two's complement arithmetic. An additional array of buffer counter/latches can be employed. Ripple counters can be configured as counters to capture the digital video level, and then as shift registers to clock out the video levels to an output bus. The clock pulses or counts for the DAC counter and for the ripple counters can be at the same or different rates.

摘要： The use of a Bayer pattern array in digital image sensors to enhance the dynamic range of the sensors is disclosed. Each Bayer pattern in the array can include three different pixels having a first exposure, and a fourth pixel (which is the same color as one of the other pixels in the array) having a second exposure. The dynamic range of the Bayer pattern array can be enhanced by using different exposure times for the pixels. Each pixel can capture only one channel (i.e. either red (R), green (G) or blue (B) light). Interpolation of neighboring pixels, including those having different exposure times, can enable the pixels in the Bayer pattern array to generate missing color information and effectively become a color pixel, and can allow the Bayer pattern array to have a higher dynamic range.
摘要翻译：公开了在数字图像传感器中使用拜耳图案阵列来增强传感器的动态范围。阵列中的每个拜耳图案可以包括具有第一曝光的三个不同像素和具有第二曝光的第四像素（其与阵列中的其他像素之一相同的颜色）。可以通过对像素使用不同的曝光时间来增强拜耳图案阵列的动态范围。每个像素只能捕获一个通道（即红色（R），绿色（G））或蓝色（B）光）。相邻像素（包括具有不同曝光时间的像素）的插值可以使得拜耳图案阵列中的像素能够产生丢失的颜色信息并有效地成为彩色像素，并且可以允许拜耳图案阵列具有更高的动态范围。
