  • Publication number: 20050253936
    Abstract: An image processing device according to the present invention comprises an image signal operation unit, a correction data operation unit and a correcting unit. The image signal operation unit adjusts a white balance of an image signal by controlling a gain of the image signal for each color constituting the image signal. The correction data operation unit creates correction data for correcting an output of the image signal operation unit. The correcting unit further corrects the output of the image signal operation unit based on the correction data created by the correction data operation unit. According to the present invention, the white balance can be appropriately adjusted without losing subtle shades and shadows of a photographic object even in the case of an image signal including a noise level of a dark current.

  • Publication number: 20050104982
    Abstract: A solid-state image sensing apparatus including a solid-state image sensing device and a signal processing circuit. The solid-state image sensing device includes: a vertical transfer unit, composed of transfer columns corresponding to columns of the light-to-electric conversion elements, operable to transfer, in a vertical direction, signal charges read out from the light-to-electric conversion elements; a horizontal transfer unit operable to receive the signal charges from the vertical transfer unit and transfer them in a horizontal direction. The signal processing circuit converts the signal charges from the horizontal transfer unit into pixel data, and rearranges it into a two-dimensional array. In the rearrangement, the signal processing circuit, per transfer of one piece of pixel data, cyclically selects a line memory out of three line memories, writes a piece of pixel data into the selected line memory, or reads a row of pixel data from the selected line memory.

  • Publication number: 20040062848
    Abstract: PROBLEMS TO BE SOLVED: To provide a highly safe lapactic agent that exhibits a sufficient lapactic effect such as the promotion of catharsis even by the intake of a small quantity, and a food product containing such a lapactic agent having a lapactic effect. MEANS TO SOLVE THE PROBLEMS: A lapactic agent comprising (A) a basic polymer and/or the salt thereof, and (B) a dietary fiber, wherein (A) a basic polymer and/or the salt thereof is at least one selected from the group consisting of polyvinylamine, polyallylamine, polyethyleneimine, polyvinylpyridine, poly (N,N-dimethylaminoethyl acrylate), &egr;-polylysine, a copolymer formed from a monomer having an amino group selected from the group consisting of vinylamine, allylamine, vinylpyridine, vinylmethylimidazole, N,N-dimethylaminoethyl acrylate, and N,N-dimethylaminopropyl acrylate; and a salt of these polymers; and a food product containing such a lapactic agent.

  • Patent number: 4070194
    Abstract: An ink for marking any fabric, which fades to disappear after use, employs a phthalein color. The fading time which is suitable for the marking ink can be regulated by the addition of ethanolamines and lower alcohols so that the phthalein color disappears naturally after from several hours to about 10 days.When a suitable ink for marking is used to mark a fabric, sewing may be followed according to the mark, and the mark disappears after a lapse of a determined time after the sewing operation is ended.The ink does not cause damage to the fabric.
