Definitions

  • the invention is in the technological field of creation, communication, and display of digital images. More specifically the invention relates to a method that enables, from a terminal or from a server, a digital image containing several images to be created; the method then enables, from a terminal comprising control and display means, an image included in the previously created container image to be selected for display. BACKGROUND OF THE INVENTION
  • the communication of digitized images, resulting for example from photographs, is largely favored by communication networks such as the Internet. Digital images are generally saved or stored in servers that can be remote from one another.
  • the network such as the Internet, enables these images to be reached by various terminals provided with control (e.g. keyboards, joystick) and display means.
  • These terminals are for example PCs (Personal Computer), or mobile terminals such as cellphones, PDAs (Personal Data Assistant).
  • the images can also be saved in terminals, and in this case, no connection to the network is necessary to recover them.
  • the images are saved as collections of images.
  • a collection of images generally comprises many images. Terminals enabling these images to be displayed are equipped with a keyboard and a display screen. In the case of mobile or portable terminals, the display screens are often small. The user of a terminal equipped with a display screen who wishes to display an image, needs to execute several operations, by using the terminal keyboard.
  • the user wants, for example, to display an image extracted from a collection of images, to view it, he/she has to execute various successive operations, by using for example the terminal keyboard: open the application enabling the display; select the collection of images; select the image of the album; open the image file; optionally, zoom in on or move within the image by translation; close the image file; select another image; open this other image's file; close this other image's file; etc.
  • This therefore requires a relatively high number of operations that have to be executed image-by-image, if the user needs to view several images of a collection, before sending them, for example, to an addressee.
  • the term addressee generally means a terminal; the terminal is remote from a server, can communicate with this server, and the terminal can display images.
  • the objective is thus to supply a faster and friendlier interface for the user who wishes to look for digital images easily and display these images on his/her terminal.
  • the solution is an interface that enables better inter-images and intra-image browsing, in order to reduce the number of operations to be executed by the user with his/her terminal.
  • Such an interface is produced at the terminal by creating container image files each comprised of individual images.
  • the advantage of this browsing is all the greater with te ⁇ ninals, like for example mobile phones or PDAs, that have a limited graphic interface.
  • the invention solves the above-mentioned problem by using a display control method of a digital image, selected from among a collection of digital images, the method comprising the following steps: first, the automatic creation of a composite image, or container image, made up of individual (selected) images, the container image being subdivided into many more-or-less adjacent areas, or tiles, and each individual image having respectively set dimensions and a set location in the container image matching one tile; second, the automatic display of the container image and the activation of each tile of the container image as a pointer to the individual image data corresponding to said tile, and, in response to the selection by a user of one of the tiles, the automatic enlarged display of the individual image corresponding to the selected tile.
  • the container image is preferably created by using the tiles principle of the known image compression process JPEG 2000.
  • JPEG 2000 compression process enables the container image to be cut automatically into tile areas.
  • the areas or tiles cutting up the contamer image are generally rectangular and identical in their geometry. These areas enable the reception of the individual images selected in the source collection of images, at a rate of one image per area or tile; and then each selected image intended to be integrated into an area of the container image is encoded separately from the other selected images.
  • each tile of the container image can be activated individually, for example with a tile selection cursor controlled with a two-way control, for displaying, modifying, or deleting an image or part of an image that it contains, without having to decode-encode all the container image.
  • the encoding of each of the individual images making up each area or tile of the container image is performed so that the selected image intended to be included in a tile of the container image complies with the aspect ratio (dimensional ratio between the width and height) of the tiles of the container image.
  • the image data of each tile are compressed data of the corresponding source image.
  • An edge of white pixels enables for example the selected image to be adjusted to be included in a tile with the tile dimensions.
  • the dimensions and location of the individual image in the container image are preferably determined automatically; but they can also be determined manually by the user with a suitable interface of the terminal.
  • the selected image displayed in a tile is matched to the capacities and dimensions of the terminal screen used, for example a portable terminal, so as to provide the user with good viewing conditions, enabling him/her to easily recognize an individual image in an container image.
  • the container image can contain individual images with different resolutions.
  • the container image is preferably subdivided into nine tiles capable of comprising respectively nine individual images. Each of these individual images or thumbnails can be selected, for example using nine corresponding keys of a numerical keyboard of the terminal.
  • full screen display also means that all the pixels of the image displayed according to the second resolution, completely fill the screen surface, i.e. 100 percent of the screen's surface.
  • full screen display at 100 percent preferably an available resolution corresponding to an image size immediately greater than the screen size is adopted, and the image is decimated so as to obtain the best compromise between the screen aspect ratio and the image aspect ratio.
  • the aspect ratio characterizes the ratio between the width and height (of the screen or the image).
  • the image is displayed in full screen, so that one of the image dimensions more or less matches one screen dimension.
  • the available resolutions are supplied by the existing standard sizes, like for example JPEG 2000. JPEG 2000 preferably enables files to be created having five different resolutions.
  • the dimensions (width and height) of the image are divided by two to go to a lesser resolution, etc.
  • the image display can thus be matched to the screen dimensions, while minimizing the volume of data to be decoded.
  • An advantageous embodiment of the invention enables the enlarged display of the selected individual image to be produced in full screen, i.e. with an enlargement such that one of the image dimensions more or less matches one dimension of a terminal display screen, by having, besides all the pixels of this first selected image that practically fill the whole screen surface, part of the pixels of at least another non-selected image and also being part of the container image.
  • This embodiment corresponds to a full screen display such that all the pixels making up the first displayed selected image do not completely fill the whole screen surface.
  • the method according to the invention also to enlarge by zooming, using the terminal keyboard, part of the selected image displayed in full screen with the second resolution.
  • the method according to the invention is preferably implemented, in an Internet type network environment, by using a mobile terminal, such as for example a cellphone or a PDA. But the method can be also implemented on a PC.
  • the method is applicable to images files saved in a server, a PC, or a mobile terminal.
  • the container image is created for example in the server, based on images remotely transmitted to the server from the mobile terminal or PC.
  • the display of the container image is then performed in the mobile terminal or PC, based on the image data for display, transmitted from the server communicating with these terminals.
  • the method according to the invention provides a solution removing all the operations of opening and closing each image file of an image set, by using a container image encoded as a single image file.
  • the user can thus display the selected image directly, based on the thumbnail that he/she points to, on his/her terminal screen.
  • the selected image is thus displayed, enlarged and matched to the terminal's screen, based on the display of a container image that includes the thumbnail (at a lesser resolution) corresponding to the image selected for full screen display.
  • a container image that includes the thumbnail (at a lesser resolution) corresponding to the image selected for full screen display.

  • Figure 3 shows an image selected according to the invention method, and displayed in full screen on the terminal.

  • DETAILED DESCRIPTION OF THE INVENTION The following description is a detailed description of the main embodiments of the invention, with reference to the figures, in which the same numerical references identify the same elements in each of the different figures.
  • Figure 1 shows an example of a network environment comprising terminals 1, 2 equipped with display means to implement the method according to the invention. In a preferred embodiment, the method is implemented by using a mobile terminal 1 , equipped with a keyboard 7 and with a display screen 6.
  • the mobile terminal 1 is a cellphone or a PDA.
  • the terminal 1 communicates with the other computers 2, 3, in a digital communication network, like for example the Internet.
  • Interactive communications of digital images can be performed, for example between the terminal 1 and a remote server 3.
  • the server 3 enables digital images to be saved, for example as a collection of 9 to N images (or 9-N).
  • the collection of images is for example an album which contains many digital images 9-N.
  • the terminal 2 is for example a PC type computer.
  • the links 4 and 5 that enable the communication of digital data between the terminal 1 and the PC 2 on the one hand, and then between the terminal 1 and the server 3 on the other hand, are performed in a network such as GSM (Global System for Mobile), GPRS (General Packet Radio System), or WIFI.
  • GSM Global System for Mobile
  • GPRS General Packet Radio System
  • the protocols used to communicate are for example of the type HTTP (Hyper Text Transmission Protocol), with the MMS infrastructure (Multimedia Message Service).
  • the link 4 between the terminals 1 and 2 can also be a wire link, or a wireless link of the infrared or bluetooth type.
  • the method enables, based on the selection (step 20) in the collection of 9 to N images saved in a directory saved in a memory of the server 3 or in a memory located in the terminal 1, 2, the automatic creation and display, according to a step 30, of at least one container image 8.
  • the container image 8 contains a set of at least one image 9 to 17 selected, according to step 20 prior to step 30, from among the collection of 9-N source images.
  • the individual images 9-17 are regrouped in the single image file of the container image 8.
  • the selected images 9-17 are preferably regrouped into a single image: the container image 8.
  • the creation of the container image 8 including the set of at least one image 9-17 is performed by the compression of each of the images 9-17, and by the division of the container image 8 into the tiles 9A' to 17 A' (figure 7), to enable the display of the contents of a compressed image 9-17 in one of the tiles 9 A' to 17 A' (or 9A'-17A') of the container image 8.
  • the creation of the container image 8 is performed on the terminal 1, 2, or the server 3.
  • a JP2 type file can be produced having a tile packet or codestream that complies with the standard JPEG 2000 part 1 (ISO 15444-1).
  • the codestream is comprised of a main header, whose data are valid for the packet set, and a tilestream set.
  • the main header describes for example the number of available resolutions in the image, the size of the image and the tiles.
  • Each tilestream is dedicated to one tile, and consists of a tile header, and compressed image data regrouped as pack stream.
  • Each tile's header contains a specific Start Of Tile (SOT) marker, which contains, among other information, the index of the tile _ ⁇ .
  • SOT Start Of Tile
  • the present invention uses the index information contained in the marker to make the link between an enlargement request for an individual image of the container image, for example visually marked by a number graphically superimposed on the image, and the addressing of the data in the physical file.
  • Several codestreams can be juxtaposed in the same JP2 or JPX file; this means that a container image file can, for example, contain several image albums that classify the images by resolution for example.
  • Files compressed using the JPEG2000 standard benefit from multiresolution acquired by wavelet compression. In the compression process using JPEG 2000, a source image is decorrelated into constituents, and each constituent is cut into tiles. Then, the dyadic transformations are applied to each of the tiles to obtain various resolutions.
  • the multiresolution aspect is provided by the transformations into successive wavelets. Based, for example, on a file having a resolution of 3000 by 2000 pixels, five successive transformations result in the following six resolutions being available: 3000 by 2000, 1500 by 1000, 750 by 500, 375 by 250, 188 by 125, and 94 by 62.
  • the application used to display and decode the images then chooses the most appropriate resolution according to the enlargement requested by the client.
  • Example of the creation and update of a container image To produce a JP2 container image, including nine regular tiles of 3000 pixels (horizontal resolution) by 2000 pixels (vertical resolution), the following steps are performed: 1. the creation of a container image comprising only pixels of uniform color (white for example) and size 9000 pixels (horizontal resolution) by 6000 pixels (vertical resolution), cut into regular tiles of 3000 by 2000 pixels (horizontal resolution by vertical resolution);
  • the container image is created by examining the resolution of each of images to be included in the tiles, and the decision on the size of the container image (and thus the tiles) is taken according to the maximum and minimal resolution of each of the source images to be included, and the minimization of their deterioration by decimation or stretching.
  • the container image 8 is cut or subdivided into a whole number of tiles.
  • this number is arbitrary, and the container image 8 can have any number of tiles.
  • the preferred number of tiles 9 A'- 17 A' of the container image 8 is nine, as described in the example above, and as shown on figures 2, 6, and 7.
  • the number of tiles of the container image 8 can be more than or equal to the number of selected images 9-17 to be included in the container image 8.
  • the number of areas of the container image 8 is more than the number of selected images 9-17, new selected images can easily be added in tiles left uniform, preferably white, of the container image 8, until the maximum number of available tiles of the container images 8 is reached. But the number of tiles of the container image 8 can also be less than the number of selected images 9-17; in this case, several container images 8 are created to contain all the selected images 9-17.
  • Each tile of the container image 8 contains the pixels of at least one image 9-17 displayed with a resolution that is typically a small resolution. These images 9-17 are displayed as thumbnails, in the corresponding areas 9A'-17A' of the container image 8. The display of the thumbnails 9-17 with the small resolution, enables an acceptable view for the user, i.e.
  • a first embodiment of the method enables going from the display of a first container image to the display of a second container image by closing, using the keyboard 7 of the terminal 1, the file of the first container image, and then opening the file of the second container image.
  • a second advantageous embodiment of the method enables the successive and automatic display, for example according to an adjustable timing, of each of the container images, without having to perform closings and openings of the respective files for these container images.
  • the invention method enables the display, in the same container image 8, of images 9-17 that have various resolutions. That is, the tile packets 9A'- 17A' are different in this same container image.
  • the algorithm of the invention method entails for example the inclusion of individual images with maximum resolution of 4 megapixels into a first tile packet, then individual images with maximum resolution of 2 megapixels into a second tile packet, and finally individual images of maximum resolution of 1 megapixels into a third tile packet. Each of these packets can be accessed, for example, by a tab displayed in the screen interface.
  • This advantage of the invention method provides the option of including, in the same container image 8, an arbitrary number of individual images 9-17, for example as mini albums of images, each corresponding to many tiles.
  • Another advantage of the invention is that the container image 8 thus created can be modified or updated, i.e. one or more individual images 9-17 can be added or removed in the contamer image, without having to decompress and recompress all these individual images of the container image.
  • the update of the container image 8 is performed on the terminal 1, or on the server 3.
  • the display of the container image 8 is performed by opening a single image file; i.e.
  • this container image 8 contains for example sixteen images, while an acceptable view, given the characteristics of the terminal used, corresponds (as shown in figure 2) to the display of only nine areas on the screen, then a first container image 8 is displayed having the first nine thumbnails, and then, a second container image 8 is displayed sequentially having the seven remaining thumbnails.
  • the display of the second container image 8 is preferably performed automatically according to a preset display timing for each container image displayed.
