[0136] The light spreading parameter determination subunit is used to determine the current ambient light spreading parameter based on the light brightness attenuation speed of the path sensor combination of all assumed light spreading lines at each assumed light source point position and the current ambient light direction.

[0140] The intersection point of each second connecting line and the illumination center line is regarded as a hypothetical light source point position, and a plurality of hypothetical light source point positions are obtained from the intersection points of a plurality of second connecting lines and the illumination center line.

[0141] In this embodiment, the ambient brightness difference between the two brightness sensors is the difference between the ambient brightness values ​​acquired by the two brightness sensors.

[0143] In this embodiment, the light brightness attenuation speed of the path sensor combination is the brightness attenuation value per unit length in the path when the ambient light propagates from the location of the brightness sensor with a larger ambient brightness value in the path sensor combination to the location of the brightness sensor with a smaller ambient brightness value.

[0144] The working principle and beneficial effects of the above technology are as follows: based on the contour differentiation subunit, the light source point hypothesis subunit, the scattering line hypothesis subunit, the sensor hypothesis combination subunit, the light brightness attenuation analysis subunit, and the light scattering parameter determination subunit, by sequentially determining multiple hypothetical light source point positions, all hypothetical light scattering lines of each hypothetical light source point position, and the light brightness attenuation rate of the sensor combination, the current ambient light scattering parameters are further refined, and the subsequent control accuracy of the light emitting parameters of the focusing LED 2 is further guaranteed, so as to ensure that the mobile phone can obtain better shooting images.

[0146] The authenticity calculation end, the light spreading parameter determination end, and the luminous parameter analysis submodule are connected in sequence;

[0147] The authenticity calculation end is used to calculate the authenticity of each assumed light source point position based on the light brightness attenuation speed of the path sensor combination of all assumed light diffusion lines at each assumed light source point position, including:

[0148]

[0149] Where γ is the authenticity of the currently calculated assumed light source point position, n is the total number of sensor combinations of all assumed light diffusion lines of the currently calculated assumed light source point position, and v is i is the light brightness attenuation rate of the path sensor combination of the i-th assumed light spreading line at the currently calculated assumed light source point position;

[0151] In this embodiment, the authenticity of the assumed light source point position indicates the possibility that the assumed light source point position is the actual light source point position.

[0152] The working principle and beneficial effects of the above technology are as follows: based on the authenticity calculation end, the light scattering parameter determination end and the above formula, the authenticity of each assumed light source point position is accurately calculated, and the real light source point position with extremely high reliability is determined, thereby achieving the final improvement of the current ambient light scattering parameters, and further ensuring the subsequent control accuracy of the light emitting parameters of the focusing LED2, so as to ensure that the mobile phone can obtain better shooting images.
