Provided are high purity sodium p-styrenesulfonate with an excellent hue which is useful as a reactive emulsifier or dispersant for producing a polymer emulsion, or synthetic starch for clothing ironing and poly(sodium p-styrene-sulfonate) with an excellent hue using the same or sodium p-styrenesulfonate improved in fluidity while keeping good solubility.

An aqueous p-β-bromoethylbenzenesulfonic acid solution and an aqueous sodium hydroxide solution are reacted under specific conditions to control the particle size, thereby obtaining sodium p-styrenesulfonate particles improved in a balance between fluidity and solubility, and further, impurities such as isomers are reduced, thereby obtaining high-purity sodium p-styrenesulfonate with an excellent hue.

The invention discloses a plasma nanoparticle dark field microimaging analysis method based on HSI color coding, and specifically relates to the field of quantitative chemistry and biochemical imaging. The method comprises the following specific analysis steps: S1, establishing an HSI color model, forming an HSI analysis basis, and the HSI color model requiring that each color can be represented by three components of hue H, saturation S and intensity I; S2, after obtaining an LSPR scattering signal of a single plasma nanoparticle, analyzing scattered light in the DFM image by using a hue value in the HSI system; and S3, perfecting the HSI color model. According to the method, the LSPR scattering signal of a single AuNP can be automatically obtained by encoding the pixels of the scatteredlight and adopting an HSI analysis method, HSI analysis is easier to implement, and the method is closer to a human visual system than RGB analysis. Besides, through computer programming, the hue value corresponding to each light spot in the DFM image can be automatically calculated and acquired, the precision is greatly improved, and personal errors are eliminated.

In a tone conversion apparatus, a decision-processing section sequentially detects a signal level difference between pixels of an image in a predetermined direction thereof by using the image signal having a first number of bits, determines whether the signal level difference remains within a preset signal level difference, and determines a pixel which has the same signal level as that of an immediately preceding pixel that encounters the signal level difference and is consecutive with the immediately preceding pixel. A bit-allocation-processing section adds a bit to the least significant bit of the image signal having the first number of bits to convert it into the image signal having second number of bits, divides the signal level difference when the signal level difference remains within the preset signal level difference, and uses the division to set the signal level difference between the consecutive pixels to the consecutive pixels.
