Problems solved by technology

[0003] Due to the mechanical structure of the mechanical shutter, there will be wear and tear in the process of opening and closing. Due to this wear, the mechanical shutter will have a limited service life. etc. In addition, because the mechanical shutter is controlled by the solenoid valve to close the mechanical blade, it takes a period of time from power-on to the complete closure of the solenoid valve suction blade, so when processing the mechanical shutter closing action, it is necessary to calculate the advance amount for operation, such as figure 1 As shown, it takes a period of time for the mechanical shutter to be completely closed (time T2) from being powered on (time T1), that is, as figure 1 As shown, in the CMOS global shutter exposure mode, after reaching the preset exposure time (T1 to T2 ...

Abstract

The invention discloses a CMOS (complementary metal oxide semiconductor) device for realizing global exposure, a terminal thereof and an exposure control method. The CMOS device for realizing global exposure includes a complementary metal oxide semiconductor (CMOS) image sensor and a substrate below the CMOS image sensor; and an electronic film is arranged between the CMOS image sensor and the substrate, so that light emitted by the CMOS image sensor can be subjected to light transmitting processing of the electronic film, and then the processed light irradiates the substrate, and therefore, the amount of the light irradiating the substrate can be changed with the light transmitting processing.

Description

technical field [0001] The present invention relates to a CMOS (Complementary Metal-Oxide Semiconductor, Complementary Metal-Oxide Semiconductor) structure improvement technology, in particular to a CMOS device for realizing global exposure, its terminal, and an exposure control method. Background technique [0002] Many existing mobile terminals (such as mobile phones, etc.) use CMOS image sensors as lenses; and many CMOS image sensors use rolling shutter exposure mode (pixel point progressive exposure), in order to avoid Exposure) when taking pictures of high-speed moving objects, there will be a jelly effect, and the global shutter exposure mode (all pixels are exposed at the same time) is often used. However, due to the limitations of the design structure of most current CMOS image sensors, after exposure with the global shutter, need Read out the exposure data line by line for a period of time, such as figure 1 The period from T2 to T3 is the process of reading out row...
