Abstract

The embodiment of the invention discloses a mobile terminal and an exposure method thereof. The mobile terminal comprises a CMOS image sensing unit and a plurality of electronic black cards. The electronic black cards are disposed at a light incoming side of the CMOS image sensing unit. The electronic black cards are transparent at a power-off state, and are not transparent at a power-on state. The mobile terminal also comprises a detection unit and a control unit. The detection unit is used for detecting a preview image collected by the CMOS image sensing unit, and recognizing a first display parameter of a first region in the preview image. The first region is any one region in the preview image. The control unit is used for controlling the power-on of the first electronic black card corresponding to the first region based on the first display parameter obtained by the detection unit. According to the embodiment of the invention, the mobile terminal achieves the brightness adjustment of a local region in the image, and solves a problem that the local exposure is not uniform in the prior art.

Description

technical field [0001] The invention relates to the technical field of photographing, in particular to a mobile terminal and an exposure method thereof. Background technique [0002] Many existing mobile terminals (such as mobile phones, etc.) use CMOS (Complementary Metal-Oxide Semiconductor) image sensors as lenses. There is a jelly effect in taking photos, and the global shutter exposure mode is often used (all pixels are exposed at the same time). However, due to the limitation of the design structure of most current CMOS image sensors, it takes a period of time to read out the exposure line by line after exposure with the global shutter. data such as figure 1 The period from T2 to T3 is the process of reading out row-by-row data. During this period of data readout, the CMOS image sensor cannot be in the exposure state, so a mechanical shutter is required. During this period of data readout Keep the mechanical shutter closed to block the light, so that the CMOS image s...
