Image processing device, image processing method, and storage medium for correcting brightness
The image processing unit selects multiple subject areas from strobe-ON image data to be corrected, and, from the selected multiple subject areas, the image processing unit acquires a feature amount such as gloss information corresponding to each subject. Subsequently, from each subject area, the image processing unit selects a part of the subject area, based on the acquired feature amount. Then, regarding the partial area of each subject area, which is selected based on the feature amount, the image processing unit estimates the auxiliary light arrival rate corresponding to each subject, based on a pixel value of the strobe-ON image data and a pixel value of strobe-OFF image data. Thereafter, based on the estimated auxiliary light arrival rate, the image processing unit corrects the brightness of each subject area of the strobe-ON image data, in order to generate corrected image data.
IMAGING DEVICE
An imaging device may include an image sensing device including a plurality of pixels to detect incident light from a scene to generate a pixel signal corresponding to the incident light and generate image data, wherein the image sensing device operates to perform imaging operation in response to a control signal, a luminance acquisition unit to acquire the image data corresponding to first pixels among the plurality of pixels associated with a target region of an image of the scene captured by the image sensing device, a controllable item acquisition unit to acquire one or more sensitivity items indicative of sensitivity of each pixel to light, as a controllable item, and a set value calculation unit to generate the control signal to the imagine sensing device by calculating a set value for the controllable item based on the image data of the target region and the controllable item.
Edge detection signal processing
To satisfactorily detect an edge detection signal of a high frequency band from a captured image signal at all times. A filtering unit extracts an edge detection signal of a high frequency band from an image signal obtained from imaging, and a band control unit controls the high frequency band on the basis of lens information. For example, the filtering unit includes a first high-pass filter with a first cutoff frequency, a second high-pass filter with a second cutoff frequency that is lower than the first cutoff frequency, and an α blending unit that performs α blending on output of the first high-pass filter and output of the second high-pass filter. Even if the frequency of the edge detection signal included in the captured image signal varies due to a change in a zoom position, a lens model number, an F value or the like, the edge detection signal can be satisfactorily detected at all times.
