  • Publication number: 20220343573
    Abstract: An image processing apparatus includes: a moving object extraction unit configured to generate, regarding a moving object extraction target image, an extracted image obtained by extracting an image of a moving object in an area other than a mask area set as an area from which an image to be used for synthesis is not extracted; and an image synthesis unit configured to perform processing of synthesizing the extracted image with another image.

  • Patent number: 8067477
    Abstract: An object of the present invention is to provide the resin composition for electro-photographic toner, which the electro-photographic toner to be obtained by it is superior to low temperature fixing properties and a hot offset resistance, and the electro-photographic toner thereof. To be achieved this purpose, multi-branched state polyester structure having a structure representing the following structural formula (1) as a repeating unit, is made into a main skeleton (In the formula, R expresses an aliphatic hydrocarbon group, and n shows the number of repeating units of a branched structure and is an average of 1-5.) *a is a node of the carbon atom of a carbonyl group, *b is a node of an oxygen atom, and *b is bonded to *a in the other repeating unit of the structural formula (1)).

  • Patent number: 6821703
    Abstract: A polyester resin particle dispersion material, in which the average particle size can be easily controlled within a broad range and is less likely to form irregular particles, and which is also suited for use in adhesives, is produced by dispersing a resin melt containing, as an essential component, a polyester resin (A) having a terminal structure in which an alkyl group having 4 to 20 carbon atoms or an alkenyl group having 4 to 20 carbon atoms is bonded to a carbon atom to which a carboxyl group is attached, or a carbon atom adjacent to this carbon atom, a portion or all of carboxyl groups in the polyester resin (A) being neutralized with a basic compound, in a heated aqueous medium in a melted state, and cooling the dispersed resin melt.
