Abstract
The present invention discloses a multimode CMOS image sensor and a control method thereof. The sensor comprises an independent control area group, a peripheral control circuit, a section mode setting module and a section mode configuration module. The method comprises dividing an independent control area group of the sensor into sections; setting a mode for each of the sections obtained; configuring a control mode of the peripheral control circuit for a corresponding section according to the mode set. By means of the present invention, when imaging in a push-broom mode, a regular sequence of images with fixed pixel difference can be produced at high frequency, and by performing pixel unmixing or integrating on the images obtained, the resolution and signal-to-noise ratio of the images can be effectively increased; because it is possible for some image unit area(s) of the sensor not to be selected as a scanning area, such design can bypass image units with quality issues when imaging by the hardware, which increases the reliability of the device; the characteristic of multiple times of imaging for the same target within very short time by multiple channels of the device can be util…
