Provided is an image acquisition apparatus including an image sensor configured to obtain an image, and a processor configured to obtain a basis based on a surrounding environment of the image acquisition apparatus, estimate illumination information based on the obtained basis, and perform color conversion on the image based on the estimated illumination information.

The present disclosure relates to image capture systems and methods. The image capture method may include obtaining first color image data including color information with an infrared light source off. The image capture method may also include obtaining first luminance image data including luminance information with the infrared light source on. The image capture method may also include generating a first enhanced image based on the first color image data and the first luminance image data.

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.

A projecting system includes an image projector that includes an optical source and that projects an image on a projected surface; and a processor. The processor obtains brightness information regarding brightness around the projected surface. The processor selects at least one item among a total luminous flux of the optical source, a color gamut of the image, and a size of the image. The processor adjusts the item that is selected based on the brightness information.

An image processing method includes: converting a red yellow blue RYB image into a grid image based on a red green blue RGB format; generating a first brightness layer of the grid image, and determining a reference gain compensation array used to adjust the first brightness layer; obtaining, based on a preset compensation array correspondence, a target gain compensation array that is associated with the reference gain compensation array and based on an RYB format; and adjusting a second brightness layer of the RYB image by using the target gain compensation array, to generate a corrected image.

A tangible, non-transitory machine-readable medium includes machine-readable instructions that, when executed, cause processing circuitry to receive a signal indicative of high dynamic range content. The signal includes 1) a first portion that forms a first percentage of the signal and is associated with a first brightness range and 2) a second portion that forms a second percentage of the signal associated with a second brightness range. The instructions, when executed, are also configured to cause the processing circuitry to produce an adjusted signal to represent the signal such that a graphical representation of the adjusted signal includes an area corresponding to the first portion of the signal that is expanded relative to a graphical representation of the first portion of the signal. Furthermore, the instructions, when executed, are configured to cause the processing circuitry to cause display of a graphical representation of the adjusted signal.
