Image processing apparatus, image processing system, and filter setting method

An image processing system used in a surveillance system, the image processing system comprising:

• a camera configured to generate image data of an image;
• and
• an image processing apparatus including
• a control device configured to
• acquire the image data from said camera,
• acquire metadata representing information concerning an object of surveillance,
• control a display to display a setting screen usable for setting a plurality of filters,
• perform filter setting using the information of the metadata, and
• set a combination of the plurality of filters,
• wherein the filter setting and setting of the combination of the plurality of filters are provided on the same setting screen,
• wherein said control device is configured to select a type of the combination of the plurality of filters being provided in the setting screen, and wherein a set combination of the plurality of filters is displayed in the setting screen with a plurality of filter types that can be set for each of the filters of the set combination,
• wherein a filter is used for detecting an event in a surveillance area in an image corresponding to the acquired image data, and
• wherein options of the type of the combination of the plurality of filters include a first mode and a second mode of the control device, in which:
• the first mode is a mode in which an alarm information is output each time when conditions of at least one of the plurality of filters in the combination is satisfied with situations based on the metadata, and
• the second mode is a mode in which an alarm trigger is output when the conditions of all filters in the combination are satisfied with situations based on the metadata.

A filter setting method used in a surveillance system, the method comprising the steps of:

• acquiring image data from a camera;
• acquiring metadata representing information concerning an object of surveillance;
• controlling a display to display a setting screen having a function of setting a plurality of filters and a function of setting a combination of the plurality of filters;
• performing, with the setting screen, filter setting using the information of the metadata;
• and
• setting the combination of the plurality of filters with the setting screen,
• wherein said setting step includes selecting a type of the combination of the plurality of filters being provided in the setting screen, and wherein a set combination of the plurality of filters is displayed in the setting screen with a list f a plurality of filter types that can be set for each of the filters of the set combination,
• wherein a filter is used for detecting an event in a surveillance area in an image corresponding to the acquired image data, and
• wherein options of the type of the combination of the plurality of filters include a first mode and a second mode, in which:
• the first mode is a mode in which an alarm information is output each time when conditions of at least one of the plurality of filters in the combination is satisfied with situations based on the metadata, and
• the second mode is a mode in which an alarm trigger is output when the conditions of all filters in the combination are satisfied with situations based on the metadata.

An image processing apparatus, comprising:

• a control device configured to
• acquire image data from a camera;
• acquire, from the camera, metadata representing information concerning an object of surveillance;
• display a setting screen usable for setting a plurality of filters;
• perform filter setting using the information of the metadata;
• and
• set a combination of the plurality of filters,
• wherein said filter setting and setting of said combination of the plurality of filters are provided on the same setting screen,
• wherein said control device is configured to switch a type of the combination of the plurality of filters, switching of the type of the combination of the plurality of filters being provided in the setting screen, and wherein the filter setting is provided in the setting screen to display a set combination of the plurality of filters with a list of a plurality of filter types that can be set for each of the filters of the set combination,
• wherein a filter is used for detecting an event in a surveillance area in an image corresponding to the acquired image data, and
• wherein options of the type of the combination of the plurality of filters are:
• a first mode of the control device configured to output an alarm each time a condition of any of the plurality of filters is satisfied by the metadata acquired from the camera, and
• a second mode of the control device configured to output one alarm when the conditions of the plurality of filters are satisfied by the metadata acquired from the camera in a set order.
