1. A display system, comprising:
- an image display device having two or more sets of images for display;
a display screen;
a camera configured to be directed toward positions adopted by user viewing said display;
a face detector configured to detect human faces in images captured by said camera, said face detector is configured to detect faces in at least two face categories, and to detect a dwell time respect to each detected face, the dwell time indicating a time period during which a detected face is oriented towards the display screen;
a selector configured to select, responsive to a frequency of detection of categories of faces by said face detector with respect to one or more different periods, a set of images to be displayed on said image display device at that period, wherein said selector is responsive to face category frequency data detected during a corresponding previous period, said previous period being a predetermined time interval; and
a statistical analyzer configured to determine a frequency of detection of categories of faces in at least one of an age or a gender category over the predetermined time interval, whereinthe selector is further configured to select a promotional display sequence stored on a data storage device and including advertising images for products or services, based on a relative frequency of detected faces in each of a different category.

13. A display method for a display system, comprising:
-
capturing images, on an image display device of the display system, of users viewing an image display device; detecting human faces in said captured images, with a face detector of the display system, said faces being detected in at least two face categories, and detecting a dwell time with respect to each detected face, the dwell time indicating a time period during which a detected face is oriented towards a display screen; selecting a set of images to be displayed on said image display device with respect to one or more different periods in response to a frequency of detection of categories of faces by said face detector at those periods, wherein said selecting is responsive to face category frequency data detected during a corresponding previous period, said previous period being a predetermined time interval; and determining a frequency of detection of categories of faces in at least one of an age or a gender category over the predetermined time interval, wherein the selecting includes selecting a promotional display sequence stored on a data storage device and including advertising images for products or services, based on a relative frequency of detected faces in each of a different category. - View Dependent Claims (14)

15. A display system, comprising:
-
an image display device having two or more sets of images for display; a display screen; a camera configured to be directed towards positions adopted by users viewing said display; face detector means for detecting human faces in images captured by said camera, said face detector detects faces in at least two face categories, and for detecting a dwell time with respect to each detected face, the dwell time indicating a time period during which a detected face is oriented towards the display screen; selector means for selecting, responsive to a frequency of detection of categories of faces by said face detector with respect to one or more different periods, a set of images to be displayed on said image display device at that period, wherein said selector is responsive to face category frequency data detected during a corresponding previous period, said previous period being a predetermined time interval; and a statistical analyzer configured to determine a frequency of detection of categories of faces in at least one of an age or a gender category over the predetermined time interval, wherein the selector means selects a promotional display sequence stored on a data storage device and including advertising images for products or services, based on a relative frequency of detected faces in each of a different category.
