The input ends of the two analog-to-digital conversion units 42 are connected, and the output end of the second analog-to-digital conversion unit 42 is connected to the output end of the first analog-to-digital conversion unit 41 .
图像传感器100的控制模块用于控制同一颜色的滤光片31所对应的多个像素单元11按照行同时曝光，图像处理模块对模数转换单元40的输出进行合成以获得高动态范围图像。The control module of the image sensor 100 is used to control multiple pixel units 11 corresponding to the filters 31 of the same color to expose simultaneously in a row, and the image processing module synthesizes the output of the analog-to-digital conversion unit 40 to obtain a high dynamic range image.
作为一个示例，像素单元阵列10内第2i+1(i＝0,1,2,3,4…)行和邻近第2i+1行的第2i+2行的每个滤光片31对应的三个像素单元(比如滤光片Gr1,Gr2、Gr4所对应的像素单元)，即第一像素单元PD1和第二像素单元PD2和第三像素单元PD3，共用一个增幅转换单元即第一增幅转换单元SF1，第一像素单元PD1、第二像素单元PD2和第三像素单元PD3产生的电荷汇集，由第一增幅转换单元SF1将汇集后的电荷转换为电压信号，并进一步通过第一模数转换单元41转换为数字信号输出，设此时第一模数转换单元41输出值为ADC1；另外，像素单元阵列10内第2i+2行的每个滤光片31的一个像素单元(比如滤光片Gr3所对应的像素单元)，即第四像素单元PD4通过第二增幅转换单元SF2进行电荷转换，最后通过第二模数转换单元42转换为数字信号输出，设此时第二模数转换单元42输出值为ADC2。As an example, each filter 31 of the 2i+1 (i=0,1,2,3,4...) row and the 2i+2 row adjacent to the 2i+1 row in the pixel unit array 10 corresponds to Three pixel units (such as the pixel units corresponding to the filters Gr1, Gr2, and Gr4), that is, the first pixel unit PD1, the second pixel unit PD2, and the third pixel unit PD3, share one amplification conversion unit, that is, the first amplification conversion unit Unit SF1, the charges generated by the first pixel unit PD1, the second pixel unit PD2 and the third pixel unit PD3 are collected, and the collected charges are converted into voltage signals by the first amplification conversion unit SF1, and further passed through the first analog-to-digital conversion The unit 41 is converted into a digital signal output, assuming that the output value of the first analog-to-digital conversion unit 41 is ADC1 at this time; The pixel unit corresponding to slice Gr3), that is, the fourth pixel unit PD4 performs charge conversion through the second amplification conversion unit SF2, and finally converts it into a digital signal output through the second analog-to-digital conversion unit 42. At this time, the second analog-to-digital conversion unit 42 The output value is ADC2.
具体地，以同一颜色的滤光片31对应2行2列相邻的4个像素单元为例，基于上述的结构，在进行HDR控制时，控制模块可以控制相邻两行的相同颜色像素同时曝光，例如，第2i+1与2i+2行同时曝光，其中，i＝0,1，2，3.....，并控制曝光时间，避免共用第一增幅转换单元SF1的三个像素单元11的输出饱和。在本发明的实施例中，增幅转换单元20可以对像素单元11输出的电荷起到汇总耦合的作用，可以理解的是，如果设第一增幅转换单元SF1输出为S1，设第二增幅转换单元SF2输出为S2，则满足S1＝3S2，所以每四个相同颜色的像素单元同时输出一个高ADC值和一个低ADC值，进而在图像传感器100的ISP(Image SignalProcessor,即图像处理器)端进行合成处理，可以实现HDR功能。Specifically, taking the filter 31 of the same color corresponding to 4 adjacent pixel units in 2 rows and 2 columns as an example, based on the above structure, when performing HDR control, the control module can control the pixels of the same color in two adjacent rows to simultaneously Exposure, for example, simultaneous exposure of rows 2i+1 and 2i+2, where i=0, 1, 2, 3..., and controlling the exposure time to avoid sharing the three pixels of the first scaling conversion unit SF1 The output of unit 11 is saturated. In the embodiment of the present invention, the amplification conversion unit 20 can play the role of collecting and coupling the charge output by the pixel unit 11. It can be understood that if the output of the first amplification conversion unit SF1 is set as S1, the second amplification conversion unit is set to The output of SF2 is S2, which satisfies S1=3S2, so every four pixel units of the same color output a high ADC value and a low ADC value at the same time, and then at the ISP (Image Signal Processor, i.e. image processor) end of the image sensor 100. Composite processing, HDR function can be realized.
如图5所示，图像传感器100还包括设置在滤光阵列30上的微镜阵列50，微镜阵列50中的每个微镜51与一个像素单元11对应，包括形成、大小、位置对应。微镜51能将光聚集到像素单元11的感光部分，提升像素单元11的受光强度，从而改善成像画质。As shown in FIG. 5 , the image sensor 100 further includes a micromirror array 50 disposed on the filter array 30 , and each micromirror 51 in the micromirror array 50 corresponds to a pixel unit 11 , including formation, size, and position correspondence. The micromirror 51 can gather light to the light-sensing portion of the pixel unit 11 to increase the intensity of light received by the pixel unit 11 , thereby improving the imaging quality.
