A personal information separation unit separates a document image containing personal information into a personal information image containing the personal information and a general information image that does not contain the personal information on the basis of the document image, and transmits the general information image to a cloud server. A recognition result integration unit receives a general recognition result that is the recognition result of the character recognition processing for the general information image from the cloud server, and acquires a target recognition result that is the recognition result of the character recognition processing for the document image in accordance with the general recognition result and the information based on the personal information image.

Terminal apparatus, character recognition system, and character recognition method

It is possible to generate a range image with higher accuracy. A range image generation apparatus includes: a light emitting unit that emits light toward an object at different light emission intensities; a light receiving unit that captures an image of the object by receiving light including reflected light from the object and calculates a light exposure amount for each pixel; and a range calculating unit that calculates a range to the object by replacing a light exposure amount at a first light emission intensity by a light exposure amount at a second light emission intensity in a predetermined case and generates a range image.

Range image generation apparatus and range image generation method

Provided is a technology for preventing a frame-out of a person from an image acquired through a camera in a behavior analysis technology using the acquired image. A behavior analysis apparatus includes: an image acquisition unit; a person image extraction unit; a person skeleton detection unit; a person behavior analysis unit; a frame-out determination unit configured to determine a frame-out of the person toward an outside of the predetermined field angle as to one of whether or not the frame-out has occurred and whether or not the frame-out is predictable through use of any one of the person image area and the person skeleton; and a frame-out notification unit configured to notify the person of the determination in one of a case where the frame-out has occurred and a case where the frame-out is predictable.

Behavior analysis apparatus and behavior analysis method

In an image pickup apparatus having an image pickup unit, a color difference signal, which is generated from signals obtained from the visible light pixels and including the near-infrared light region, and a color difference signal, which is generated by removing the signals of the near-infrared light region, are combined, at a combination ratio that is in accordance with a saturation degree of the signal components of the visible light region, and then outputted. In this way, the hue can be reproduced with colors close to colors viewed by a person. A similar processing may be performed for the brightness signals. If the color difference signal generated by removing the signals of the near-infrared light region exhibits, for example, a negative value, then the signals of the near-infrared light region may be added again.

Image pickup apparatus

Provided is an image-capturing device including: a visible light signal generating unit that extracts a visible light signal from a pixel signal from an image-capturing element; a light source color estimating unit that estimates a color temperature of a light source from the visible light signal; a white-balance adjusting unit that performs white balance correction on the visible light signal according to an estimation result; a non-visible light signal generating unit that extracts a non-visible light signal from the signals from the image-capturing element; and an image composing unit that combines and outputs the visible light signal on which the white balance correction was performed and the non-visible light signal.

Image-capturing method and image-capturing device

The imaging device is characterized by comprising an image sensor comprising pixels with sensitivity to the visible range and near infrared range and pixels with sensitivity to the near infrared range, a color reproduction processing unit that performs color reproduction processing using signals from the pixels with sensitivity to the visible range and near infrared range and signals from the pixels with sensitivity to the near infrared range among the output signals of the image sensor, a visible light amount calculating unit that calculates the signal quantity in the visible range using the output signal of the image sensor, and a control unit that controls the color reproduction processing unit so that the color reproduction processing is performed on the basis of the signal quantity in the visible range calculated by the visible light amount calculating unit.
