Description

METHOD AND APPARATUS FOR ASSOCIATING ENVIRONMENTAL INFORMATION WITH DIGITAL IMAGES
Description BACKGROUND OF THE INVENTION
The present invention relates generally to camera images, and more particularly, to associating environmental information with camera images, particularly digital camera images.
As digital photography increases in popularity, common users will be able to store thousands of digital images, while professional photographers will need to store hundreds of thousands of images. As such, finding a stored image may be quite difficult for the typical photographer.
One possible solution is searching the images for image content. This technique requires the user to specify some characteristic of the image, such as a tall building. A computer searching for the images must then search the images for this characteristic. This technique requires sophisticated software, which has thus far not been completely successful, and is not an efficient method for locating images.
As such, there is a need for methods and apparati to improve ones ability to locate a digital image amidst a plurality of digital images. DESCRIPTION OF THE INVENTION
Accordingly, the present invention is directed to a digital camera configuration that substantially obviates one or more of the problems due to limitations and disadvantages of the prior art.
In accordance with the purposes of the invention, as embodied and broadly described herein, the invention comprises a digital camera configuration including a digital camera for capturing a digital image, means for storing the digital image, means for generating environmental information, and means for storing the generated environmental information. In another aspect, the digital camera configuration includes means for receiving user information corresponding to a digital image and for storing this information. In yet another aspect of the invention, the digital camera configuration includes means for storing information regarding the camera itself. The summary of the invention and the following detailed description should not restrict the scope of the claimed invention. Both provide examples and explanations to enable others to practice the invention. The accompanying drawings, which form part of the description for carrying out the best mode of the invention, show several embodiments of the invention, and together with the description, explain the principles of the invention.

Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Figure 1 illustrates a block diagram of a digital camera configuration 5 according to a preferred embodiment of the invention. As shown in Figure 1, the digital camera configuration 5 includes an image capture device 10, an Analog to Digital Converter (ADC) 20, a Digital Signal Processor (DSP) 30, means for generating environmental information 40, and a storage device 50. In a preferred embodiment the image capture device can be a Charged Coupled Device (CCD), but Complementary Metalic Oxide Semiconductor (CMOS) devices are equally applicable to this invention, as well as other optical sampling devices which generate pixels. The image capture device 10 sends analog voltage information corresponding to image pixels to the ADC 20, which converts the analog signals into discrete binary signals. The digital output from ADC 20 is sent to DSP 30, which adjusts contrast and color balance, and subsequently compresses the image before sending it to the storage 50. The storage device, in a preferred embodiment, includes RAM chips, but in another embodiment, may comprise any appropriate storage medium such as, magnetic disks or memory cards. In another embodiment, the image capture device 10 can be a complementary metal-oxide semiconductor (CMOS). Because of the nature of CMOS, it is possible to task the CMOS with other responsibilities, such as the Analog to Digital Conversion (ADC) and some signal processing tasks.
In addition to the above, the digital camera configuration 5 of the preferred embodiment also includes means for generating environmental information 40 associated with a digital image. Environmental information includes information relating to the environment in which a digital camera image is captured. For example, environmental information includes location, the lighting conditions, altitude, odor, camera orientation, and various atmospheric conditions, of which temperature, humidity, wind speed and direction are examples. In one embodiment, an Analog to Digital Converter (ADC) is used to convert analog signals which describe the environmental information into a digital form prior to storing the information in storage 50. In another embodiment, the means for generating environmental information generates digital information directly. In a preferred embodiment, the digital environmental information is sent to
DSP 30, which combines the environmental information with the captured image and sends both digital data sets to storage 50.
In one embodiment, the environmental information is stored by storage 50 in files ancillary to the captured digital image. In another embodiment, the environmental information is embedded within the digital image file stored in storage 50 by using fields reserved in that file for user information. In another embodiment, the environmental information is imbedded in the image itself by an encoding technique that modifies the information in the image in such a way that the image visually appears unaltered but the environmental information is recoverable using special techniques. This is sometimes known as watermarking. In this case as well, the digital information is ultimately stored in storage 50.
In a preferred embodiment the means for generating environmental information includes a location-sensing device so that the camera's location at the time of digital image capture can be determined. Location information can include longitude and latitude (as well as altitude) as determined by a Global Positioning Satellite system (GPS), or the latitude and longitude could be converted into an address using maps, such as Sony's Etak system.
In another embodiment, the means for generating environmental information includes a light spectrum analyzer for generating information regarding the lighting conditions at the instant of image capture.
In another embodiment, the means for generating environmental information includes a humidity sensing device, such as solid-state sensor which compares air moisture to a sealed air sample as a reference. Humidity sensors provide digital signals which represent the relative humidity at their sensing location. In another embodiment, the means for generating environmental information includes a digital thermometer for generating information regarding the temperature when a digital image is captured.
In another embodiment, the means for generating environmental information includes an altimeter to provide information on elevation relative to sea level. Other forms of altimeters could also be used for providing information regarding how high the camera was above the ground when a digital image was captured. Ultra-sonic sensors, which are used to determine distance from the sensor to a reflecting surface, could be mounted on the bottom side of the digital camera to determine the distance from the camera to a support surface. Multiple time samples of this information could be used in this invention to determine if the camera is held by a human being, with the attendant motion of the camera prior to image capture, or by a tripod or similar device which would have a very constant distance from the camera to the support surface.
In another embodiment, the means for generating environmental information includes a rangefinder for generating information regarding the distance between the digital camera and the object being photographed. The rangefinder can be optical (using edge sharpening techniques) or sonic to provide accurate digital distances from the camera sensor to the object located in the center of the camera viewfinder. In another embodiment, the means for generating environmental information includes an inclinometer for generating information regarding the orientation of the camera on three axes at the time a digital image is captured.
In another embodiment, the means for generating environmental information includes a gas chromatograph for providing information regarding odors where the digital image is captured. This information can include odors such as bromine and methane, or gas concentrations such as the relative amounts of oxygen or nitrogen or nitrogen-oxides that might be present in the location when the image is captured.
In another embodiment, the means for generating environmental information includes an accelerometer for generating information regarding movement of the camera at the time a digital image is captured. In another embodiment, the means for generating environmental information includes an anemometer for generating information regarding wind speed and direction at the time a digital image is captured.
In another embodiment, the means for generating environmental information includes a barometer for generating information regarding atmospheric pressure at the time a digital image is captured.
In another embodiment, the means for generating environmental information includes a compass for generating information regarding the direction or orientation of the camera at the time a digital image is captured. In another embodiment, the means for generating environmental information includes a depth meter for generating information regarding how far underwater the digital camera is at the time a digital image is captured.
As shown in Figure 2, in another embodiment the digital camera configuration 5 includes a flash 110, and means for generating information regarding the flash 140. In this embodiment, the digital camera configuration 5 generates and stores information regarding characteristics of the flash used by the digital camera configuration 5 when a digital image is captured. For example, flash intensity, flash duration, flash orientation relative to the optical axis of the camera, and flash feedback from its sensing element measuring the reflected light coming back from the photographed scene.
As shown in Figure 3, in another embodiment, the digital camera configuration 5 stores a camera identification code 210. In this embodiment, the digital camera configuration 5 stores information regarding the camera identification code for the camera associated with a capture digital image. For example, this code is often a serial number of the camera that is unique to that model of camera. Another example of the camera identification code is the a digital model number or serial number of the lens being used during the photograph, or of the specific type of filter used with the camera, of the specific type of flash unit attached to the camera. In another embodiment, the digital camera configuration 5 stores information regarding a film identification code associated with film used by the digital camera configuration 5 when a digital image is captured. The film used here might be the type of conventional film used in a dual exposure camera where a digital image and a conventional film image are captured at the same instant. This film type could be specialized optical film to capture different spectra from the scene other than the conventional optical spectra. Examples of these other spectra are Ultraviolet (UV) and Infrared (IR). Sampling of radio wave emissions could be taken at the same time as the digital optical information and that radio wave signal could be digitized and included as part of the environmental identification. As shown in Figure 4, in another embodiment, the digital camera configuration 5 includes an input/output interface 310. In one embodiment, the digital camera configuration 5 is capable of receiving user information input associated with a captured digital image through a keyboard or digital writing pad via input/output interface 310.
In another embodiment, the digital camera configuration 5 is capable of receiving user information input associated with a captured digital image through a microphone via input/output interface 310.
In another embodiment, the digital camera configuration 5 is capable of receiving user information associated with a captured digital image input through a Personal Digital Assistant (PDA) via user interface 310.
As shown in Figure 5, in another embodiment, the digital camera configuration 5 includes means for generating information regarding an eye of a photographer for a captured digital image 410. This information can include, e.g., information regarding an iris or other part of the eye of the photographer. This information could indicate the retinal pattern of the photographer's eye as a means of uniquely identifying the photographer, or as a means of determining where the photographer was looking into the scene in the viewfinder to help identify the dominant object in the scene. In another embodiment, the digital camera configuration 5 includes means for generating information regarding a fingerprint of the photographer for a captured digital image. Using an optical window on the side of the digital camera, the photographer's fingerprint could be captured during the scene capture using either the same image capture element as used for the primary scene (typically CCD or CMOS device) or the fingerprint device could be an entirely different sensor. New fingerprint sensors are becoming available which image a fingerprint by non-optical means. This invention covers all types of fingerprint sensor mechanisms. As shown in Figure 6, in another embodiment, the digital camera configuration 5 includes a computer interface 510 for connecting the digital camera configuration 5 to a computer. Through this interface the digital camera 5 can receive information associated with a captured digital image from the computer. The digital camera configuration 5 then stores the information received from the computer in a manner that the received information is associated with the digital image. As previously noted, there are two preferred methods for storing this information: in ancillary files, or by embedding the information in the stored image. While it has been illustrated and described what is at present considered to be the preferred embodiment and methods of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made, and equivalents may be substituted for elements thereof without departing from the true scope of the invention.
In addition, many modifications may be made to adapt a particular element, technique or, implementation to the teachings of the present invention without departing from the central scope of the invention. Therefore, it is intended that this invention not be limited to the particular embodiment and methods disclosed herein, but that the invention includes all embodiments falling within the scope of the appended claims.
