1. A processing system for simultaneously presenting brightness performance of different areas on a single display screen, comprising:
a detection processor, for performing a multi-point photometry in a pre-imaging area of a display device after the display device is installed or projected for viewing to find out an ambient light intensity distribution presented in each spot on the single display screen after the display device is installed; and
a control processor, telecommunicatively coupled to the detection processor, for cutting a screen range of the display device into a plurality of modulation areas according to a difference of an ambient light intensity distribution presented in the pre-imaging area,
wherein the control processor adjusts outputs of a first portion of the plurality of modulation areas, corresponding to a portion with a relatively stronger ambient light sensitivity in the pre-imaging area, to have a relatively higher brightness display performance,
the control processor adjusts outputs of a second portion of the plurality of modulation areas, corresponding to a portion with a relatively weaker ambient light sensitivity in the pre-imaging area, to have a relatively lower brightness display performance, and
the control processor adjusts one or a combination of an outputted current value and an outputted Gamma value of the plurality of modulation areas to realize that the plurality of modulation areas has different brightness display performance,
wherein the detection processor is used for setting and cutting the pre-imaging area into a plurality of light sensing elements, and the control processor cuts the screen range of the display device into a plurality of dimming elements corresponding to the plurality of light sensing elements,
the control processor determines an ambient light intensity of each light sensing element and other light sensing elements adjacent to the light sensing element, and calculates a multiple relationship by dividing a light sensing element that presents a relatively stronger ambient light intensity by a light sensing element that presents a relatively weaker ambient light intensity, and
when the multiple relationship is greater than or equal to a predetermined multiple, a divided section is defined and formed between two dimming elements corresponding to two neighboring light sensing elements that satisfy a condition of the predetermined multiple, and then at least one cutting line continuously formed by a plurality of divided sections, including the divided section, cuts the screen range of the display device to form the plurality of modulation areas.
