Problems solved by technology

[0002] At present, the general method for the frame rate and exposure control of the image sensor is to use the soc (System-on-a-Chip, system on chip) to send the frame rate control command to the image sensor through the I2C bus. I2C pins, however, for hardware systems with tight embedded resources, the use of soc pins is very tight, often not enough pins are available, so it is necessary to propose a technical means to meet the basic functional requirements of image sensors ( Under the premise of adjusting the frame rate and image brightness), the pins of the soc can be saved as much as possible

Abstract

The invention discloses an image sensor frame rate and exposure control system and method. The system comprises an Soc and an image sensor; the Soc is connected with the image sensor through an Mclk pin and a Pclk pin so as to provide a working clock for the image sensor and receive a synchronous clock which is output by the image sensor and represents image pixels, and the Soc realizes frame rate and exposure control of the image sensor by controlling the frequency of a working clock Mclk output to the image sensor.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to an image sensor frame rate and exposure control system and method. Background technique [0002] At present, the general method for the frame rate and exposure control of the image sensor is to use the soc (System-on-a-Chip, system on chip) to send the frame rate control command to the image sensor through the I2C bus. I2C pins, however, for hardware systems with tight embedded resources, the use of soc pins is very tight, often not enough pins are available, so it is necessary to propose a technical means to meet the basic functional requirements of image sensors ( Under the premise of adjusting the frame rate and image brightness), the pins of the soc can be saved as much as possible. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the object of the present invention is to provide an image sensor ...
