Thio(meth)acrylates, mixtures for preparing transparent plastics, transparent plastics, and method for their production and use

Abstract

To inexpensively detect a change, which occurs in an image photographed by an imaging means, with low power consumption and by a small amount of storage capacity.An integrated circuit device 10 includes an image change detecting circuit 20 for time-sequentially receiving image data 12 which are photographed by the imaging means 110, detecting the change of the image, and generating a change detection signal. The image change detecting circuit 20 divides the image into one or a plurality of areas, and includes an integrating circuit 30 that integrates the pixel values of pixels belonging to each area by unit of one or the plurality of areas concerning the image data of the first and second images which are time-sequentially received, and holds the integrated values in cumulative registers 50, 60; and a change detection signal generating circuit 40 for comparing the integrated values of the corresponding areas in the first and second images held in the cumulative registers 50, 60, detecting existence of the change, and generating the change detection signal 14 when existence of the change is determined.

Description

technical field [0001] The present invention relates to thio(meth)acrylates and mixtures for the production of transparent plastics comprising these thio(meth)acrylates. The invention also relates to transparent plastics which can be produced from said mixtures, and to processes for their production. The invention also relates to the use of transparent plastics for the production of optical lenses, especially ophthalmic lenses. Background technique [0002] Glasses are now no longer indispensable in everyday life. Among them, spectacles with plastic lenses have recently received particular attention because they are lighter and less shatterable than spectacle lenses made of inorganic materials and can be colored with suitable dyes. For the production of plastic spectacle lenses, thiourethane compounds which can be formed, for example, from diethylene glycol bis(allyl carbonate) (DAC), with α,ω-terminated multiple bonds or sulfur-containing (formazol) are generally used.
