| Techniques to adaptively select bracket settings during auto-exposure bracket (AEB) operations are described. In general, AEB settings for a current image may be based on the evaluation of prior bracketed images. For example, the current exposure setting established by an auto-exposure mechanism (EV0) may be compared with a prior EV0 image. If the two are consistent, the prior image's lower and upper f-stop setting images (EV− and EV+) may be used to adaptively change the bracket settings for the current image's EV− and EV+ images. In another implementation, the most recently obtained EV− and EV+ images may be used to adaptively change the bracket settings for the current image—no prior capture being necessary. | ||||||

| A bracketing exposure control camera having a total exposure shift range calculated based on the number of frames and the exposure shift amount.

| A camera capable of restarting the bracketing exposure mode even after all the frames of a film have been exposed during the bracketing exposure mode. An output derived from detector for detecting the trailing end of a film is delivered to controller which controls the arithmetic operation for obtaining an optimum exposure value as well as the bracketing exposure so that in response to the above-stated output, the controller inhibits the shutter release after the end of the film, but maintains the bracketing exposure mode. Furthermore, the remaining exposures of a predetermined number of exposures in the bracketing exposure mode are cancelled at the end of the film. | ||||||

| A bracketing exposure control camera is structured in such a manner that a preset number of frames for bracketing photography is compared with the actual number of frames exposed so far in bracketing photography and exposure control operation is forcibly stopped upon detecting that the preset number of frames has been exposed. The bracketing exposure control camera can perform bracketing photography of a plurality of frames with a motor drive device, and will not waste film when the operator continues to depress the shutter release button after bracketing photography has been completed. | ||||||

| Systems and methods are presented for generating a new digital output image by blending a plurality of digital input images capturing the same scene at different levels of exposure. Each new pixel for the new digital output image is derived from a group of corresponding aligned pixels from the digital input images. For each group of corresponding pixels from the digital input images, an average color value in a first color space is derived by taking a separate average across each color channel of the first color space. The resulting average color value in the first color space is modified in order to raise its corresponding color saturation value in a second color space. The new pixel's color value in the first color space is set to the modified average color value. | ||||||

In particular, a display is provided for each exposure value for all frames to be used in the automatic exposure bracketing and the exposure compensation value set by an exposure compensation value setting circuit using the same indicator. When performing the above-described display, the set compensation value is displayed as the exposure value of one frame for automatic exposure bracketing, and the exposure values of the other frames are displayed in correlation as the amounts of deviation from that compensation value. | ||||||
| 20 | Blending of Exposure-Bracketed Images Using Weight Distribution Functions | US12713258 | 2010-02-26 | US20130114894A1 | 2013-05-09 | Vikas Yadav; Alok Kumar Singh |
| Systems and methods are presented for generating a new digital output image by blending a plurality of digital input images capturing the same scene at different levels of exposure. Each new pixel for the new digital output image is derived from a group of corresponding aligned pixels from the digital input images. In order to determine a weight for each pixel in each group of mutually-aligned source-image pixels, a weight distribution function is applied to values of an image characteristic for the pixels in the group of corresponding aligned pixels, and a net weight is subsequently assigned to each of the pixels in the group. Pixel values of pixels in each group of mutually-aligned source-image pixels are modified based on the net weights assigned to the pixels in order to obtain a new pixel value for a corresponding new pixel in the new digital output image. | ||||||
