  • Patent number: 10447930
    Abstract: A monitoring camera sets ON or OFF of swing correction in accordance with setting information about whether or not the swing correction of an image (that is, captured image) captured by an image sensor is performed, and corrects swing by cutting out a part of the captured image based on a swing detected value of a vibration sensor in a case where the swing correction is set ON. The monitoring camera outputs the captured image while maintaining a state thereof in a case where the swing correction is set OFF.

  • Publication number: 20190161465
    Abstract: A method for producing a red colorant composition derived from iridoid compounds, including a step of performing red color development that involves reaction of iridoid aglycones having a carboxyl group at position 4 of an iridoid skeleton with amino group-containing compounds, said red color development being performed in a solution in which ascorbic acid, similar compounds thereof, or two or more compounds selected from the group consisting of said ascorbic acid and said similar compounds are contained at a molar ratio of 5 or more with respect to all iridoid compounds in the solution, whereby red colorant compounds having acid resistance are generated.
