Fogging in photography is the deterioration in the quality of the image caused either by extraneous light or the effects of a processing chemical.

Non-magnetic single-component toner, method of preparing the same, and image forming apparatus using the same

A non-magnetic single-component toner 8 of the present invention has toner mother particles 8a, and external additives 12 comprising: two hydrophobic silicas 13, 14 of which particle diameters are different from each other, i.e. a mean primary particle diameter of 7 nm to 12 nm and a mean primary particle diameter of 40 nm to 50 nm, and a hydrophobic rutile / anatase type titanium oxide 15 having a spindle shape of which major axial diameter is in a range from 0.02 nm to 0.10 nm and the ratio of the major axial diameter to the minor axial diameter is set to be 2 to 8, wherein the external additives 12 adhere to the toner mother particles 8a. By the hydrophobic silicas 13, 14 having work function smaller than the work function of the toner mother particles 8a, the negative charging property is imparted to the toner mother particles 8a and the fluidity is also insured. On the other hand, by mixing and using hydrophobic rutile / anatase type titanium oxide particles 15 having work function larger than or equal to the work function of the toner mother particles 8a together with the hydrophobic silicas 13, 14, the non-magnetic single-component toner 8 is prevented from excessively charged. Therefore, the amount of fog toner on non-image portions is reduced, the transfer efficiency is further improved, the charging property is further stabilized, and the production of reverse transfer toner is further inhibited.

Secondary estimation method for an atmospheric transmissivity image in a defogging process

The invention discloses a secondary estimation method for an atmospheric transmissivity image in a defogging process. The secondary estimation method comprises the following steps: acquiring an atomization degraded image in haze weather; Obtaining a dark channel image by using region minimum filtering; Obtaining a global atmospheric light value and the original scene transmissivity of the image according to the dark channel image; Filtering the original scene transmissivity by adopting a guide filter to obtain coarse estimation of the scene transmissivity; Performing minimum variance median guided filtering on the rough estimation of the scene transmissivity to obtain the final scene transmissivity; And restoring the atomized degraded image by using the final scene transmissivity. Scene transmissivity is secondarily estimated through minimum variance median guided filtering, internal texture information of the image can be effectively reserved, the problems that texture information andedge information of the restored image are lost when a traditional dark channel defogging algorithm is used for obtaining the restored image are solved, the image restoration quality is improved, andcompared with a traditional algorithm, the internal information of the image is better reserved.
