摘要： A device, method, computer useable medium, and processor programmed to automatically generate tone mapping curves in a digital camera based on image metadata are described. By examining image metadata from a digital camera's sensor, such as the light-product, one can detect sun-lit, high-light, and low-light scenes. Once the light-product value has been calculated for a given image, a tone mapping curve can automatically be generated within the sensor and adjusted appropriately for the scene based on predetermined parameters. Further, it has been determined that independently varying the slopes of the tone mapping curve at the low end (S0) and high end (S1) of the curve results in more visually appealing images. By dynamically and independently selecting S0 and S1 values based on image metadata, more visually pleasing images can be generated.

摘要： An imaging processing device and method where, when areas having a luminance difference set by a user, for example, 45 dB or more, are preset in an image captured by a camera, an area, the luminance level of which exceeds a predetermined threshold level, may be displayed as a gray level or a black level, with the luminance thereof decreased by a certain luminance level, or may be displayed while a mask, having a gray or black level, and the area, the luminance level of which exceeds the predetermined threshold level, overlap each other. Therefore, glare caused by a high luminance subject can be decreased, or other subjects present in a backlit image can be easily recognized.

摘要： A final-correction-value acquisition unit performs, for each frame, reduction processing for reducing a difference in gamma correction value between frames and thereby acquires a final correction value of the frame. The final-correction-value acquisition unit determines into which type an observed frame is classified among a first-, a second- and a third-type frames, and controls a level of the reduction processing on the observed frame according to a determined type of the observed frame, the first-type frame being a frame having a change amount obtained from a change-amount calculator equal to or smaller than a predetermined threshold, the second-type frame being a frame having a change amount larger than the threshold and at least one frame having a change amount larger than the threshold exists within a preceding predetermined period immediately before the observed frame, the third-type frame being a frame other than the first- and second-type frames.
