An apparatus includes an acquisition unit configured to acquire a pair of first data and second data, the first data being obtained by imaging an object under a first environment, the second data being obtained by imaging the object under a second environment, and a processing unit configured to generate a three-dimensional lookup table by using the pair of the first data and the second data, the three-dimensional lookup table holding a condition for image processing to convert the first data into the second data.

An imaging unit 23 generates an image signal of a captured image. An optical sensor unit 25 generates a sensor signal that has a wider view angle than that of the imaging unit 23 and is according to a spectral characteristic upon obtaining the captured image. A controller 50 determines reliability of a light-source estimation result based on the image signal generated by the imaging unit 23, using a light-source estimation result based on the sensor signal generated by the optical sensor unit 25. For example, the controller 50 classifies the light-source estimation result based on the image signal into categories of light sources capable of being estimated based on the sensor signal, and compares the category into which the light-source estimation result is classified with the light source estimated based on the sensor signal. In a case where the light source estimated based on the sensor signal is not changed when the category into which the light-source estimation result is classified is changed, it is determined that the light-source estimation result based on the image signal is not reliable, and an adjustment value of white balance adjustment is not updated. Then, the white balance adjustment can accurately and stably be performed.

Multi-color flash with image post-processing that uses a camera device with a multi-color flash and implements post-processing to generate images is described. In one aspect, the multi-color flash with image post-processing may be implemented by a controller configured to control a camera and flashes of at least two different colors. The controller may be configured to cause the camera to acquire a first image of a scene while the scene is being illuminated with the first flash but not the second flash, then cause the camera to acquire a second image of the scene while the scene is being illuminated with the second flash but not the first flash, and generate a final image of the scene in post-processing based on a combination of the first image and the second image.

A medical control device includes circuitry configured to: control an autofocus operation on a captured image from an observation target illuminated with excitation light of a first wavelength band and a pattern image of a second wavelength band, the observation target fluorescing in response to the excitation light to output light in a third wavelength band. The captured image includes light components in the first to third wavelengths bands, of which the second and third wavelength bands are different. The autofocus operation is controlled by calculating, based on the pattern image of the second wavelength band in the captured image, an evaluation value used in an autofocus process that controls a focus position of an imaging device configured to generate the captured image.
