Patent number: 6510520Abstract: A secure storage device with the external dimensions of a PCMCIA card, for securing digital camera data at the acquisition stage. Original digital camera data is saved in the memory of the secure storage device which has the capability of performing one or more security functions, including encryption, creation of an authentication file, adding data to the image data such as fingerprinting, and adding secure annotations such as separate data included in an image header. The device prepares original authentication data from original digital camera data, and encrypts and stores both the original authentication data and the original image data. The use of the device includes downloading the original image data to a first computer, and encrypted original authentication data to a second computer. The second computer can be programmed with software whereby the encrypted original authentication data can be decrypted by a user having a key.Type: GrantFiled: June 26, 1998Date of Patent: January 21, 2003Assignee: Fotonation, Inc.Inventor: Eran Steinberg

Patent number: 6433818Abstract: A programmable digital camera requiring a programming password to be entered to access the camera's programmability. The camera further includes programming so as to allow the camera to be operated only for a specified time interval, after which the camera becomes inoperable until the programming password is again entered and the camera is programmed to operate for another interval of time. An alternate embodiment of the invention includes a programmable digital camera as above described wherein the camera is programmed to only capture a set number of images, at which point the programming password must again be entered and the camera reset for another quantity of images. A further alternate embodiment includes a camera system with a separate transmitter for radiating a signal designed to cover a designated area, the signal being modulated with a camera operational code. The camera is equipped with a corresponding receiver and demodulator to receive the operational code.Type: GrantFiled: July 15, 1999Date of Patent: August 13, 2002Assignee: FotoNation, Inc.Inventors: Eran Steinberg, Yuri Prilutsky

Patent number: 6151073Abstract: An intelligent flash system for a digital camera having components including an image optical pickup, an interface circuit, a flash unit and a processor. Upon activation of the camera, ambient lighting conditions are evaluated and if flash energy is required, a first low energy pre-flash is radiated, the reflected light received by the optical pickup having a multiplicity of pixels, and the output of the pixels converted to image intensity data by the interface circuit. The processor samples the image intensity data, weighing the center image area more heavily, and creates a histogram plot of quantity of pixels v.s. intensity, and separates the plot into a bar graph from which a determination of exposure is obtained. The histogram is then used to calculate a multiplicative scaling factor used to multiply the first flash energy to an estimate of a flash energy for correct exposure. Conditions of extreme over and under exposure result in the activation of a second flash at an adjusted energy level.Type: GrantFiled: March 28, 1996Date of Patent: November 21, 2000Assignee: FotoNation, Inc.Inventors: Eran Steinberg, Hari Vasudev, Sumat Mehra

Patent number: 5862218Abstract: A camera with a built in microprocessor system programmed to receive an input password and indicium from a host computer. The camera is configured to use the indicium in combination with a conversion formula to mark an original acquired image in a non-destructive manner to form modified image data and add the indicium to an image header. The camera also creates image authentication data for comparison with corresponding data of a questionable second image to determine if the second image is the same as or different from the original image. This process of marking and creating authentication data all occur during acquisition and prior to any image data storage in a medium from which a person could subsequently access data. The camera takes the authentication data and stores it along with the marked image data in memory for subsequent transmission to the host computer.Type: GrantFiled: April 4, 1996Date of Patent: January 19, 1999Assignee: FotoNation, Inc.Inventor: Eran Steinberg

Patent number: 5862217Abstract: A digital camera method and apparatus providing encryption of an image during the acquisition process, and therefore avoiding any stage wherein unencrypted image data exists. An encrypted password is generated. This is done either by a user and downloaded to the camera, or it is generated in the camera and displayed to the user. Inside the camera, an encryption generator is initialized upon reception and successful decryption of the password, whereupon light is admitted from an object to be photographed and converted to digital image data. The camera then performs a first encrypting operation on the digital image data to create temporarily encrypted image data. This encrypted data is saved temporarily, whereupon it is decrypted in increments and each increment processed to form processed image data. Each increment then undergoes a second and final encryption operation to create final encrypted image data which is stored in the camera for transmission to a computer.Type: GrantFiled: March 28, 1996Date of Patent: January 19, 1999Assignee: FotoNation, Inc.Inventors: Eran Steinberg, Vasily Yeremenko
