An engagement estimation device includes an engagement estimation unit which calculates an estimated value of an index for assessing engagement of a viewer of a video at a certain elapsed time from a start of playback of the video distributed via a network, and the engagement estimation unit calculates the estimated value such that, in the case where the playback of the video is stopped at the certain elapsed time, the stop of the playback influences the estimated value more significantly than in the case where the playback of the video is not stopped at the certain elapsed time.

Devices, methods, and non-transitory program storage devices (NPSDs) are disclosed to compensate for the predicted color changes experienced by camera modules after certain amounts of time of real world use. Such color changes may be caused by prolonged exposure of optical components of the camera module to one or more of: solar radiation, high temperature conditions, or high humidity conditions, each of which may, over time, induce deviation in the color response of optical components of the camera module. The techniques disclosed herein may first characterize such predicted optical change to components over time based on particular environmental conditions, and then implement one or more time-varying color models to compensate for predicted changes to the camera module's color calibration values due to the characterized optical change. In some embodiments, optical changes in other types of components, e.g., display devices, caused by prolonged environmental stresses may also be modeled and compensated.

An information display apparatus 400 obtains information about a plurality of apparatuses for obtaining a plurality of images captured from a plurality of directions for use in generating a virtual viewpoint image corresponding to a specified viewpoint. Furthermore, the information display apparatus 400 identifies an apparatus in an abnormal state among the plurality of apparatuses based on the obtained information. The information display apparatus 400 then causes the display unit 404 to display information indicating one or a plurality of apparatuses, among the plurality of apparatuses, that are in a predetermined relationship with the apparatus in the abnormal state.

An image signal processor and an image sensor including the same are disclosed. An image sensor includes a pixel array configured to convert received optical signals into electrical signals, a readout circuit configured to convert the electrical signals into image data and output the image data, and an image signal processor configured to perform deep learning-based image processing on the image data based on training data selected from among first training data and second training data based on a noise level of the image data.

A calibration operation support device is applied to a system including an industrial camera and a display device displaying a predetermined image that is an image of a predetermined area being captured by the industrial camera, and includes a processing device configured to perform a calibration of the industrial camera based on captured images that are obtained by capturing a calibration pattern by the industrial camera. The processing device is further configured to instruct the display device to display positions of the calibration patterns in the captured images acquired as images to be used for the calibration in a manner superimposed on the predetermined image.

A method operable by circuitry including an image processor, an image sensor, and another clock-dependent device, including measuring a flicker using the image sensor, adjusting a clock rate of the circuitry according to the measured flicker, and operating the clock-dependent device using the adjusted clock rate.

A test device which is convenient for fast testing of cameras being mass-produced and providing a test environment without contamination by reflected light, comprises a housing, a mounting member, a test card, and a light source assembly. The housing is a testing cavity and, at opposite ends, defines a testing hole and a light through hole lined up on center axis of the housing. A distance between an inner wall of the housing and the central axis gradually increases from the testing hole to the light through hole. The test card is arranged in the testing cavity. The light source assembly is connected to the mounting member and covers the light through hole. Sides of the housing illuminated by the light source assembly absorb all light emitted by the light source assembly.

The present application discloses an image processing method, apparatus, device and storage media. A specific implementation solution is: obtaining an original image and a noise-added image, where the noise-added image is an image of the original image after a noise is added, and a number of pixels with a noise in the original image is less than a preset number; encoding and decoding the original image and the noise-added image respectively, to obtain a first decoded image corresponding to the original image and a second decoded image corresponding to the noise-added image; obtaining a first PSNR between the first decoded image and the original image according to the original image and the first decoded image; obtaining a second PSNR between the second decoded image and the noise-added image according to the noise-added image and the second decoded image; and outputting the first PSNR and the second PSNR.

A WiFi camera includes an accelerometer and detects mechanical shock events. An electronic processor is communicatively coupled to the accelerometer and produces a record of the shock events detected by the accelerometer. The electronic processor performs shock monitoring while the camera is in low power and sleep modes. A system-on-chip performs shock monitoring while the camera is in full operation, standby and idle modes.

A throughput division means (11) divides a throughput of a communication between a video delivery server configured to deliver, in a plurality of delivery modes, video data to a user terminal device used by a user and the user terminal device in a delivery period of the video data, according to a period of each delivery mode. A playback bit rate estimation means (12) estimates a playback bit rate of the video data, based on a throughput divided according to a period of the delivery mode. Thus, estimation precision of a video playback bit rate can be improved even when a video delivery server delivers video data in a plurality of delivery modes.
