Texture image acquisition method, texture image acquisition circuit and display panel
A texture image acquisition method, a texture image acquisition circuit and a display panel are provided. The texture image acquisition circuit includes a photosensitive circuit, the texture image acquisition method includes: allowing the photosensitive circuit to receive light from a texture, and obtaining a first curve based on a signal amount accumulated by the photosensitive circuit within a first integral time period, the first curve being a time-varying curve of a residual signal amount which is a signal amount remaining after a signal amount, left over by the photosensitive circuit before the first integral time period, is released over time; obtaining a first acquisition value based on a signal amount accumulated by the photosensitive circuit within a second integral time period which is after the first integral time period; obtaining a first photosensitive signal of an image of the texture; based on the first curve and the first acquisition value.
