Embodiment Construction

[0044] figure 1 A device for assisting in capturing an image according to the present invention is shown.

[0045] The device to help capture images includes: an analysis module 20, which is suitable for analyzing images that must be captured. More specifically, the module 20 analyzes the visual content of the image to calculate perceptual interest data. The perceptual interest data item can be calculated for each image pixel or for an image pixel group (for example, pixel block). Advantageously, the perceptual interest data is used to determine the region of interest in the image, that is, the region that attracts the observer's attention.

[0046] To this end, the method described in European Patent EP04804828.4 published on 30 / 06 / 2005 based on the number 1695288 can be used to calculate perceptual interest data, also called saliency value, for each image pixel. figure 2 The method shown includes: first a spatial modeling step, and then a temporal modeling step.

[0047] The spa...

Abstract

The invention relates to a device for helping the capture of images (1) comprising: analysis means (20) suitable to calculate perceptual interest data for regions of an image having to be captured, display means (30) suitable to overlay on the image at least one graphic indicator indicating the position of at least one region of interest in the image. The invention also relates to an image capture device comprising the device for helping the capture of images (1) according to the invention.

Description

Technical field [0001] The present invention generally relates to the field of image analysis. More specifically, the present invention relates to a device for assisting in capturing an image and an image capturing device including the assisting device. Background technique [0002] Currently, when a photographer shoots a scene, in addition to directly observing the scene through the camera viewfinder, the only way for the photographer to ensure that the scene he is shooting is correctly framed is by using the return channel or by using oculometric tests. ). [0003] Observing the scene directly via the viewfinder does not always enable the photographer to frame the scene correctly, especially in the case of fast movements (eg, sports scenes). It may also be difficult for the photographer to determine how to frame the scene when the scene includes many areas of perceived interest (for example, in a panorama). [0004] The use of the return channel allows, for example, a director t...
