Image forming apparatus and method for driving light source

An image forming apparatus includes: an image processor configured to perform first image processing on image data having a first resolution and to add tag data to a target pixel where second image processing is to be performed; a resolution converter configured to convert the image data into image data having a second resolution higher than the first resolution, and to perform the second image processing based on arrangement of the image data having the first resolution and the tag data; a pulse generator configured to generate an on-off modulation signal and an application-current switching signal in accordance with the image data having undergone the second image processing; and a light source driver configured to drive the light source in accordance with a current setting value output from an application current setter depending on the application-current switching signal and the on-off modulation signal.

PROVIDING CAMERA SETTINGS FROM AT LEAST ONE IMAGE/VIDEO HOSTING SERVICE

Camera settings are provided by retrieving, based on current metadata defining a current position of a camera (5) and from a storage, metadata defining respective positions of other cameras and camera settings used by the other cameras when taking photos or videos that are uploaded on an image/video hosting service. Information representative of camera settings used when taking a photo/video selected among the photos/videos available on the image/video hosting service is provided for transmission to the camera (5).

PRINTING SERVICE SYSTEM AND PRINT TERMINAL
20180285037 · 2018-10-04 · ·

The invention includes a print terminal that prints input image data and outputs the input image data as a print image, and an image storage server that is connected to the print terminal via a public network, and that stores the image data sent from the print terminal and user identification information. The print terminal creates, out of the print image, user identification information based on photographing location information and photographing date/time information included as data in a user identification information image specified by the user. In a case where the print terminal receives a re-input of image data of the user identification information image, the print terminal resends user identification information to the image storage server. In a case where an image directory including the resent user identification information internally exists, the image storage server sends the image data in the image directory to the print terminal.

Dynamically implementing an image protection policy

Technologies for dynamically implementing an image protection policy include a camera device with a camera to capture an image of at least one person. The camera device determines a location in the image of at least one person in the image, determines a location of at least one personal computing device, and maps the personal computing devices to the persons captured in the image based on the determined device and image locations. The camera device may broadcast an announcement of the creation of the image to the personal computing devices, negotiate an image protection policy with each of the personal computing devices, and implement the negotiated image protection policy.

Metadata-driven method and apparatus for constraining solution space in image processing techniques

Methods and apparatus for constraining solution space in image processing techniques may use the metadata for a set of images to constrain an image processing solution to a smaller solution space. In one embodiment, a process may require N parameters for processing an image. A determination may be made from metadata that multiple images were captured with the same camera/lens and with the same settings. A set of values may be estimated for the N parameters from data in one or more of the images. The process may then be applied to each of images using the set of values. In one embodiment, a value for a parameter of a process may be estimated for an image. If the estimated value deviates substantially from a value for the parameter in the metadata, the metadata value is used in the process instead of the estimated value.

IMAGE SHOOTING APPARATUS FOR ADDING INFORMATION TO IMAGE
20180213093 · 2018-07-26 ·

According to an embodiment of the present invention, an image shooting apparatus includes an imaging unit, a transmission unit, and a processor that is configured to acquire an image captured by the imaging unit to generate a shot image and control the transmission unit to transmit, to an information acquiring apparatus, (i) the shot image, and (ii) instruction information for instructing the information acquiring apparatus to acquire supplementary information, with a shooting instruction. The supplementary information is information which is acquired by a sensor of the information acquiring apparatus and which is to be added to the transmitted shot image.

STORAGE OF METADATA AND IMAGES
20180211355 · 2018-07-26 ·

Media capture apparatus and methods for obtaining metadata. Metadata may be collected and stored in a container independent of audio and/or image (media) content. Some container implementations may be configured to store metadata for a given interval, and media content for a portion of the interval. In action camera implementations, metadata may provide a context related to time, physical conditions of a person, location, surroundings of the video capture. In event recording applications, the metadata container may provide information related to a timeline of the event, environmental conditions, proximity of other capture devices. Metadata may be utilized for processing, viewing, and/or sharing of media content. Individual capture devices may communicate and/or combine metadata to one another in order to expand metadata content. Metadata, video and/or images may be shared between users and/or devices using a container.

DETERMINING IMAGE FORENSICS USING AN ESTIMATED CAMERA RESPONSE FUNCTION
20180197004 · 2018-07-12 ·

An image forensics system estimates a camera response function (CRF) associated with a digital image, and compares the estimated CRF to a set of rules and compares the estimated CRF to a known CRF. The known CRF is associated with a make and a model of an image sensing device. The system applies a fusion analysis to results obtained from comparing the estimated CRF to a set of rules and from comparing the estimated CRF to the known CRF, and assesses the integrity of the digital image as a function of the fusion analysis.

Authentication and validation of smartphone imagery

A method, system, and processor-executable software for processing images or video captured by a smartphone or other digital image capture device for subsequent validation and authentication captures not only the image, but also metadata relevant to the authenticity of validity of the image, such as position, time, camera movement and orientation, image parameters, and so forth. The image is watermarked and both the watermarked image and the metadata, as well as a symmetric key used in the watermarking, are digitally signed and transmitted or uploaded to a web server or authentication centric entity for authentication and storage. When a third party submits an image to the web server or authentication centric entity, the submitted image is compared with the stored watermarked image for authentication and validation of the submitted image, and the metadata is then retrieved to enable analysis of the contents of authenticated and validated image.
