Abstract
Disclosed is an apparatus and associated method an apparatus and method for assessing visual acuity of an image captured by a digital security camera. The user is able to select a desired level of visual acuity based on displayed sample images and receive data regarding the hardware, settings, and placement required to reproduce the desired level of acuity. The sample images may account for acuity variations based on the type of object being imaged.
Claims14
An apparatus for assessing visual acuity comprising:
- a processor;
- a memory operatively connected to the processor;
- an electronic display operatively connected to the processor;
- and
- a user input device;
- wherein the apparatus is configured to prompt the user to selected an object type to be evaluated by a selected camera and a desired visual acuity index level;
- wherein a sample image of the selected object type is displayed on said display, said image having a level of visual acuity matching the desired visual acuity index level;
- and
- wherein the apparatus executes computer readable instructions to determine the maximum allowable field of view that is achievable using the selected camera while maintaining the desired visual acuity index level.
A method for generating and displaying a visualization of the visual acuity of an image that will be produced using a selected camera in a video surveillance system, comprising:
- maintaining a set of images within a computer database, said set of images corresponding to a plurality of visual acuity index levels and a plurality of object types;
- prompting a user to select an object type and a desired visual acuity index level;
- retrieving a first one of said images from the database, said first image having a level of visual acuity matching the desired visual acuity index level, said image depicting the selected object type;
- displaying said first image on an electronic display.
