HIGH DYNAMIC RANGE IMAGE SENSOR READ OUT ARCHITECTURE |
| 摘要 |
A method of controlling a pixel array includes reading out image data from pixel cells of a row i of the of the pixel array with second transfer control signals that are coupled to be received by transfer transistors included in the pixels cells of the row of the of the pixel array that is being read out. Exposure times for pixel cells are independently controlled in other rows of the pixel array that are not being read out with first transfer control signals coupled to be received by transfer transistors included in the pixel cells in the other rows of the of the pixel array that are not being read out while the image data is read out from the pixel cells of row i of the pixel array. |

1. A method of controlling a pixel array, comprising:
reading out image data from pixel cells of a row i of the of the pixel array with second transfer control signals coupled to be received by transfer transistors included in the pixels cells of the row of the of the pixel array that is being read out; and independently controlling exposure times for pixel cells in other rows of the pixel array that are not being read out with first transfer control signals coupled to be received by transfer transistors included in the pixel cells in the other rows of the of the pixel array that are not being read out while the image data is read out from the pixel cells of row i of the pixel array. |
