An imaging apparatus includes an optical element configured to separate incident light into light components in at least two types of wavelength bands. The incident light includes light emitted from a narrow-band light source. At least one light component of the light components in the at least two types of wavelength bands separated by the optical element is light in a narrow band separated by a bandwidth corresponding to a width of a wavelength of the light emitted from the narrow-band light source.

Imaging apparatus

An imaging apparatus according to an embodiment includes a first light source which emits first light, a second light source which emits second light, an imaging sensor, and control circuitry. The image sensor includes a plurality of pixels to receive light from an object, reads an electric signal generated by the pixel with a rolling shutter method, and outputs the electric signal for each frame. The control circuitry causes the first light source to be turned on M (M is an integer equal to or less than N) times in N frames in synchronization with a first period based on a blanking period of the frame, and causes the second light source to be turned on by selectively using multiple lighting patterns in which lighting timing is set in synchronization with the first period and a total lighting period in the N frames is different.

Imaging apparatus and control method having a plurality of synchronized light source devices

According to one embodiment, an imaging apparatus includes an image sensor, image generation circuitry, calculation circuitry and superimposition circuitry. The image generation circuitry successively generates a first image and a second image. The calculation circuitry calculates a first parameter to allow brightness of the first image to be equal to or close to a predetermined value, and calculates a second parameter relating to brightness of the second image based on the first parameter and a predetermined ratio. The superimposition circuitry generates a composite image by superimposing the second image in which the brightness is adjusted using the second parameter onto the first image in which the brightness is adjusted using the first parameter.

Imaging apparatus and imaging method

An imaging device according to an embodiment includes an image sensor, and processing circuitry. The image sensor is a rolling-shutter type image sensor that includes a plurality of pixels that are arranged in a matrix and generate an electric signal due to light received and, on a frame-to-frame basis, repeatedly performs a process to sequentially start to conduct exposure on at least every line, starting from the first line of the pixels to the last line, and output the electric signal sequentially from the line for which exposure has been completed. The processing circuitry causes the pixels to receive light during only a period based on the blanking period that corresponds to the period from when the output of the electric signal from the last line is finished until the output of the electric signal from the first line is started. The processing circuitry generates images in accordance with the electric signal.
