Image Sensor with Integrated Power Conservation Control

摘要

An integrated image sensor circuit with multiple power modes is disclosed. The integrated circuit comprises a pixel array, an analog block to process analog signal associated with the pixel array, where the analog block comprises an analog to digital convertor (ADC), and a first control circuit to enable/disable the analog block or to configure the analog block to a high/low-power mode depending on whether the pixel array is in a readout frame or in a reset frame with no active readout. The integrated image sensor circuit may further comprise a post-processing block and a second control circuit to enable/disable the post-processing block or to configure the post-processing block to the high-power mode or the low-power mode depending on whether the pixel array is in the readout frame or in the reset frame with no active readout.

1. An integrated image sensor circuit, comprising:
a pixel array to capture an image projected thereon; at least one analog block to process analog signal associated with the pixel array, wherein said at least one analog block comprises an analog to digital convertor (ADC); and a first control circuit to enable or disable said at least one analog block or to configure said at least one analog block to a high-power mode or a low-power mode depending on whether the pixel array is in a readout frame or in a reset frame with no active readout.
