  • Patent number: 9542730
    Abstract: Image processing is performed in view of the difference between the chroma component and the brightness component in an image, with a relatively smaller amount of data processed during the image processing. A frequency decomposing unit 110 performs frequency decomposition directly on Bayer image signals from an imaging element 3. With this, a high frequency component representing color information and a low frequency component representing brightness information are obtained. A filter coefficient obtaining unit 131 of a correction processing unit 130 obtains filter coefficients and the filter coefficients for the high frequency component are different from those for the low frequency component. A filtering processing unit performs a filtering process on subimages based on the filter coefficients obtained by the filter coefficient obtaining unit 131 in such a manner that processing details of the filtering process for the high frequency component are different from those for the low frequency component.

  • Publication number: 20130317759
    Abstract: An evaluation indicator is calculated to determine whether or not servicing is required, from data for evaluation for a valve that is subject to servicing. An ID of the valve is recorded in a recording area AR1. A pre-servicing evaluation indicator for the valve is recorded in a recording area AR2. A post-servicing evaluation indicator for the valve is recorded in a recording area AR3. If only a pre-servicing evaluation indicator are recorded corresponding to the valve, then a status wherein the service has not been completed is presented together with the evaluation results that are indicated by these pre-servicing evaluation indicators, where if both a pre-servicing evaluation indicator and a post-servicing evaluation indicator are recorded, then a status that service has been completed is presented together with the evaluation results showing the pre-servicing evaluation indicator and the post-servicing evaluation indicator.
