An image capture device assembly includes a light source that emits a reference light pattern, an image capture device, and a control device that controls the light source and the image capture device. The light source emits the reference light pattern to a subject with high brightness and low brightness, respectively, under the control of the control device. The image capture device captures an image of the reference light pattern and the subject in a high brightness irradiation state and outputs a first image signal to the control device. The image capture device captures an image of at least the subject in a low brightness irradiation state and outputs a second image signal to the control device. The control device generates a reference light pattern image signal from a difference between the first image signal and the second image signal.

Capture device assembly, three-dimensional shape measurement device, and motion detection device

An imaging apparatus is disclosed. The apparatus includes: a solid-state imaging device provided with a plurality of arranged light-sensitive devices each having sensitivity to light in a range from a visible region to an infrared region; a first filter for transmitting light in the visible region to a first part light-sensitive device out of the plurality of light-sensitive devices; a second filter for transmitting light in the infrared region to a second part light-sensitive device out of the plurality of light-sensitive devices; and a signal processing section for changing a ratio between an electrical signal converted by the first part light-sensitive device and an electrical signal converted by the second part light-sensitive device used as an electrical signal used for deciding exposure in accordance with intensity of the electrical signal converted by the first part light-sensitive device.

Method of controlling imaging apparatus

A video input processor is disclosed. The processor includes: an imaging signal-generating portion configured to image a subject and producing first imaging signals containing visible light components and a second imaging signal containing near-infrared light components; a gain adjustment portion configured to adjustably set a maximum gain value according to a relative magnitude between the visible light components and the near-infrared light components and adjust a gain for the first imaging signals at the set maximum gain value; and a noise reduction portion configured to reduce noises in the first imaging signals after the gain has been adjusted.

Imaging apparatus and method of controlling imaging apparatus for determining exposure based on intenisty signals from color filter pixels or infrared pixels

An image input processing apparatus includes: an optical band separating filter; a color filter of a four-color arrangement having an equivalence in which the sum of two colors is equivalent to one other color in the visible light region or the sum of three colors is equivalent to once or twice one other color in the visible light region; an optical sensor section that generates an imaging signal; a data separating section that separates the pixel data of the imaging signal into pieces of pixel data of four colors; an infrared separating section that performs infrared separation by a subtraction using the equivalence among the pieces of pixel data of the four colors after the separation; a first and second integration sections; a camera control processing section that determines which of the integration values from the first and second integrating sections is used.

Image input processing apparatus and method

An electronic camera comprises a flash unit. When the electric camera takes a picture using the flash unit, the electronic camera determines a first optimum flash exposure for a central area of the object to be taken and a second optimum flash exposure for a background area of the object to be taken. Further, the camera produces first image data corresponding to a picture taken under the first optimum flash exposure and second image data corresponding to a picture taken under the second optimum flash exposure. The central area of the first image data is cut out from the first image data and written over the second image data.
