Abstract: Data is encoded in a solid state image sensor that includes a sensor pixel array by varying the color processing applied to at least some of the border pixels of the sensor pixel array. Data may be encoded in the color processing by varying the pattern of a color filter mosaic and by varying a pattern of a microlens array in accordance with a predetermined scheme. This scheme includes omission of color filter material and omission of the microlens array from selected pixels. The data, typically encoded in a binary format, is read by illuminating the sensor pixel array and by processing the output signals from the border pixels. The encoded data may include color process codes, mask revision codes and product codes.

Abstract translation: 通过改变应用于传感器像素阵列的至少一些边界像素的颜色处理，数据被编码在包括传感器像素阵列的固态图像传感器中。 可以通过改变滤色器马赛克的图案并根据预定方案改变微透镜阵列的图案，在颜色处理中对数据进行编码。 该方案包括省略滤色器材料并从所选像素中省略微透镜阵列。 通常通过照亮传感器像素阵列并且通过处理来自边界像素的输出信号来读取通常以二进制格式编码的数据。 编码数据可以包括颜色处理代码，掩码修改代码和产品代码。
