An imaging apparatus includes an image sensor, a controller, and a user interface. The image sensor captures a subject image to generate imaging data. The controller performs repair processing to generate a moving image file from a corrupted file, the moving image file being capable of reproducing a moving image indicated by the imaging data, the corrupted file having a defect as the moving image file. The user interface inputs a user operation related to the repair processing. The controller receives a user operation selecting a specific corrupted file from one or more of corrupted files via the user interface, and performs the repair processing on the selected corrupted file in response to the user operation.

Imaging apparatus

An imaging apparatus includes: an image sensor that captures a subject image by receiving light of a plurality of colors, to generate image data; a controller that controls the image sensor; and an adjuster that adjusts a light reception rate, in each position on an incident surface, the light reception rate allowing the image sensor to receive the light color by color, the incident surface being entered by the light corresponding to an image represented by the image data. The controller controls the adjuster to render the light reception rate of a specific first color in a position corresponding to part of the image on the incident surface different from the light reception rate of a first color in other positions, and causes the image sensor to capture the image with the light reception rate of the first color rendered different by the adjuster, generating image data representing the image.

An imaging apparatus includes: an image sensor that captures a subject image to generate image data; an output interface that outputs information to a user; and a controller that controls the output interface, based on recording data and the image data generated by the image sensor, the recording data recording information on a first moving image, wherein the controller causes the output interface to output shooting assist information during shooting of a second moving image with the image sensor, the shooting assist information assisting the user to match the second moving image with the first moving image.

Imaging apparatus and information presentation system

An imaging apparatus includes: an image sensor that captures a subject image by receiving incident light, to generate image data; a controller that controls an image shooting operation using the image sensor; a recorder that records the image data as a result of the image shooting operation; and an adjuster that adjusts a light reception rate in each position on an incident surface, the light reception rate allowing the image sensor to receive the light, the incident surface being entered by the light corresponding to an image represented by the image data. The controller controls the adjuster to render the light reception rate in a position corresponding to part of the image on the incident surface different from the light reception rate in another position thereon, and causes the image sensor to capture the image with the light reception rate rendered different by the adjuster in the image shooting operation.

A signal processing device includes an input interface, an image processor, an audio processor, and a controller. The input interface receives signals of a video and an audio acquired concurrently in a space where subjects exist. The image processor recognizes subject images in the video, to determine a first type of area where each subject exists. The audio processor recognizes sound sources in the audio, to determine a second type of area where each sound source exists in the space, independently of the first type of area. The controller uses the first and second types of areas to judge coincidence or non-coincidence between a position of the each subject and a position of the each sound source, to determine a combination of a subject and a sound source whose positions coincide with each other. The controller selectively determines the subject image to be output that corresponds to the combination.

Signal processing device and signal processing system

An imaging apparatus includes: an image sensor configured to capture a subject to generate image data; an audio input device configured to input audio to generate an audio signal indicating audio to be collected during image capturing with the image sensor; a setting interface configured to set the imaging apparatus to an auto mode being an operation mode operable to automatically change a directivity of the audio input device in response to an instruction of a user; and a controller configured to control a sound collection area for collecting sound from the subject in the audio signal, wherein with the auto mode being set by the setting interface, the controller is configured to control the sound collection area to cover the subject by changing the directivity of the audio input device in linkage with an image shooting state of the imaging apparatus.

[Problem] In a conventional multilayer optical disc, management information needs to be retrieved from the control area of its reference layer to find how many information layers there are in the optical disc. [Means for Solving the Problem] A multilayer optical disc according to the present invention has multiple information layers that are stacked one upon the other. The information layers include at least one layer on which layer number information, indicating its own place in the multiple information layers, and information about the total number of information layers included are both stored.

Multi-layer optical disc and optical disc apparatus

The present invention provides a method for determining what group a given multilayer optical disc belongs to. The disc is one of a number of multilayer optical discs, which are designed so that information stored is retrievable from any of the discs by irradiating the disc with a light beam having the same wavelength and which have been classified into multiple groups. According to this method, performed first is Step (A) of measuring either a distance from a first one of multiple information layers of the given multilayer optical disc to a second one thereof, which is located adjacent to the first information layer, or a distance from the first information layer to the surface of the optical disc. Next, Step (B) of determining, by the distance measured, what group the given multilayer optical disc belongs to is performed.
