An imaging system includes a pixel array configured to generate image charge voltage signals in response to incident light received from an external scene. An infrared illumination source is deactivated during the capture of a first image of the external scene and activated during the capture of a second image of the external scene. An array of sample and hold circuits is coupled to the pixel array. Each sample and hold circuit is coupled to a respective pixel of the pixel array and includes first and second capacitors to store first and second image charge voltage signals of the captured first and second images, respectively. A column voltage domain differential amplifier is coupled to the first and second capacitors to determine a difference between the first and second image charge voltage signals to identify an object in a foreground of the external scene.

The present invention provides a process for producing a fine organic pigment which is capable of efficiently atomizing a raw material organic pigment, and excellent in productivity of the fine organic pigment. The present invention relates to a process for producing a fine organic pigment which includes the step of kneading a mixture prepared by compounding a raw material organic pigment, a water-soluble inorganic salt, a water-soluble organic solvent and a resin, in which the resin is a copolymer produced by copolymerizing an aromatic ring-containing ethylenically unsaturated monomer (A), a carboxy group-containing ethylenically unsaturated monomer (B) and an ethylenically unsaturated monomer (C) containing a polyethyleneoxide chain having an average molar number of addition of ethyleneoxide of not less than 1 and not more than 50.

A transparent solid glue, in mass percentage comprises: 10.0%-50.0% of glycerol, 5.0%-20.0% of propylene glycol, 5.0%-30.0% of sticky substance, 1.0%-10.0% of stearic acid, 0-5.0% of vegetable oil, 0.5%-5.0% of protopine, 0.1%-5.0 of excipient, 0.1%-0.5% of preservative, and 5.0%-70.0% of deionized water, wherein the excipient is C.sub.12-16 saturated or unsaturated fatty acid salt. The prepared transparent solid glue has high initial viscosity; and the drying time is controllable so that the gluing position of the objects to be glued can be adjusted according to actual requirements, which is convenient to use, and the glue exhibits strong adhesion after completely drying. Meanwhile, the addition of protopine causes the pH of the solid glue to be between 10.49-10.99, and accordingly the solid glue is an environmentally friendly solid glue. Within a temperature range from −5° C. to 40° C., this solid glue is widely applicable to gluing paper, wood pieces, photographic paper, paperboards and etc.
