Definitions
- a sequence of still digital images is often used for presentations, or for atmospheric display. Sometimes the ordering of those images is such to tell a story, where on other occasions the images are ordered to match an ambience.
- An example is a digital photo frame connected to an ambient light source (like a LivingColors lamp); where for each image the ambient light is automatically adjusted to match with the current image being displayed. The matching could be based on the most dominant colour of an image, or the colour of the ambient lighting or light source reflected in the image results in an ambient lighting that is appealing.
- a method of generating a sequence of a plurality of images to be displayed with ambient lighting comprising the steps of: extracting at least one feature of each of a plurality of images; selecting ambient lighting to be displayed with each of the plurality of images on the basis of the extracted at least one feature; determining an order for display of the plurality of images on the basis of the selected ambient lighting to provide a smooth transition in changes in the ambient lighting during display of said plurality of images according to the order.
- apparatus for generating a sequence of a plurality of images to be displayed with ambient lighting
- the apparatus comprising: an extractor for extracting at least one feature of each of a plurality of images; a selector for selecting ambient lighting to be displayed with each of the plurality of images on the basis of the extracted at least one feature; and a processor for determining an order for display of the plurality of images on the basis of the selected ambient lighting to provide a smooth transition in changes in the ambient lighting during display of the plurality of images according to said order.
- the extracted at least one feature comprises colour and the ambient lighting to be displayed with each of said plurality of images is selected having a colour corresponding to the most dominant colour of each of the plurality of images, or alternatively, having a colour corresponding to the colour of the light source reflected in the image.
- the order for display of the plurality of images is determined by converting the colour of the selected ambient lighting to HSV colour space; and determining a first order for display of the plurality of images such that changes in colour of the selected ambient lighting are in accordance with the hue circle; and ordering the plurality of images according to the determined first order.
- the order for display of the plurality of images may be determined on the basis of reordering the order for display of the plurality of images at least once such that changes in colour of said selected ambient lighting are in accordance with the hue circle for images having a saturation and/or value meeting a predetermined condition , for example, reordering such that changes in colour of the selected ambient lighting are in accordance with the hue circle for images having a saturation and value greater than a first predetermined value, and/or reordering the plurality of images such that changes in colour of the selected ambient lighting are in accordance with the hue circle for images having a saturation and value within a range of the first predetermined value and a second predetermined value.
- the first predetermined value may be greater than the second predetermined value.
- the viewing effect may be further improved by excluding images for display having a saturation and value of less than a predetermined threshold, i.e. dark images or images having a very low saturation which may be less interesting when displayed with ambient lighting.
- the output terminal 109 of the apparatus 100 is connected to a display 115 and an ambient light source 117.
- the display 115 may be a display of a PC, digital photo frame, display of a digital camera and/or a projector and projector screen, or a television screen or the like.
- the ambient light source 117 may be a LivingColors lamp or an array of coloured light sources or the like.
- PCA does the following: starting from the average RGB values as a point of origin, the axes are transformed into 3 new axes in such a way that the first axis (the principal component) is responsible for most of the variation in the set of pixels.
- the principal axis can also be regarded as the result of least squares estimation.
- the final step is to estimate the point on the principal axis that corresponds to the actual light source. This can be done by projecting the pixels on the principal axis and check where the contribution is significant (i.e. avoid taking a single pixel because it might be there because of encoding).
- the result is the light source entering the scene in the image.
- the light source itself is not visible in the image. In case there is no light source available, the algorithm will yield the most dominant color of the image, which is very reasonable and looks very natural. This can be done for parts of an image as well to find light sources for a region of interest.
- the processor 107 converts the colour of the selected ambient lighting to the HSV color space, that is, the hue as defined by the HSV colour space (Hue Saturation Value) for that colour, step 205.
- the hue of any colour has a hue value.
- the hue value is an angular value, normally represented as a number in the interval [0,360). This defines a hue circle representing each hue value.
- the colours of the ambient light source and hence the images are ordered to follow the hue circle, step 207.
- the atmosphere the LivingColors lamp
- the atmosphere slowly follows the hue circle as well, providing a smooth transition of changes in the ambient lighting.
- the 3 -dimensional nature of the colour is taken into account.
- the images are then reordered, step 209 using components of saturation and value of the colour.
- Reordering means that the order in the presentation is changed.
- the order in which the images are stored or the order in a stored list that refers to the images is not necessarily changed.
- a stored list that refers to the images is ordered based on hue value and the stored list is then cycled through multiple times based on saturation and value.
- the method can be used to leave out less interesting images.
- less interesting images are referred to as those images that do not match with a colour that can easily be used to enhance the ambience. For example dark images or images with very low saturation, step 213.
- the order of the images is then output, step 215, by the processor 107 to the controller 113.
- the controller 113 then retrieves the images from the storage means via the second input terminal 110 and controls the display 115 and the ambient light source 117 to provide a display of the images and lighting according to the order.
- the colours of the ambient lighting are very appealing for use in light effects, and the transitions between the colors are relatively smooth.
- 'Means' as will be apparent to a person skilled in the art, are meant to include any hardware (such as separate or integrated circuits or electronic elements) or software (such as programs or parts of programs) which reproduce in operation or are designed to reproduce a specified function, be it solely or in conjunction with other functions, be it in isolation or in co-operation with other elements.
- the invention can be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer. In the apparatus claim enumerating several means, several of these means can be embodied by one and the same item of hardware.
- 'Computer program product' is to be understood to mean any software product stored on a computer-readable medium, such as a floppy disk, downloadable via a network, such as the Internet, or marketable in any other manner.
