Image capture method and systems to preserve apparent contrast of an image
Methods and systems are described for processing an image captured with an image sensor, such as a camera. In one embodiment, an estimated ambient light level of the captured image is determined and used to compute an optical-optical transfer function (OOTF) that is used to correct the image to preserve an apparent contrast of the image under the estimated ambient light level in a viewing environment. The estimated ambient light level is determined by scaling pixel values from the image sensor using a function that includes exposure parameters and a camera specific parameter derived from a camera calibration.
Controlling exposure based on inverse gamma characteristic
An image capturing control apparatus includes a detection unit configured to detect a specific object area in an image captured by an image capturing apparatus, an acquisition unit configured to acquire a first input/output characteristic of the image capturing apparatus, a conversion unit configured to convert the image by acquiring a second input/output characteristic that is an inverse input/output characteristic to the first input/output characteristic, and by applying the second input/output characteristic to the image, and a control unit configured to control exposure of the image capturing apparatus based on a luminance value of the specific object area in the converted image.
IMAGE CAPTURE DEVICE WITH INTERCHANGEABLE INTEGRATED SENSOR-OPTICAL COMPONENT ASSEMBLIES
An image capture device includes an image capture module and a base module. The image capture module is releasably connectable to the base module. The image capture module includes an integrated image sensor and optical component for capturing image data. The base module includes a processor. The processor is configured and the base module is calibrated based on identification data provided by the image capture module when releasably connected to the base module. The image information and identification data may be wirelessly transferred from the image capture module to the base module.
IMAGING APPARATUS
Provided is an imaging apparatus capable of continuously imaging a natural video even though brightness is changed. In an imaging apparatus in which an exposure condition is set based on a characteristic of a transmittance control element, a first exposure condition range is calculated based on photometry of the imaging apparatus. Determination is made whether or not the calculated first exposure condition range is included in a second exposure condition range where a control range acquired by the transmittance control element is applicable. In a case where the calculated first exposure condition range is not included in the second exposure condition range, the exposure condition of the imaging apparatus is changed such that the first exposure condition range is included in the second exposure condition range.
