A system, method, and computer program product are provided for high-dynamic range images. In use, a first pixel attribute of a first pixel is received and a second pixel attribute of a second pixel is received. Next, a scalar based on the first pixel attribute and the second pixel attribute is identified. Finally, the first pixel and the second pixel are blended, based on the scalar, wherein the first pixel is brighter than the second pixel. Additional systems, methods, and computer program products are also presented.

A system, method, and computer program product are provided for obtaining multiple exposures with zero interframe time. In use, an analog signal associated with an image associated with an image of an image sensor is received. Amplified analog signals associated with the image are generated by amplifying the analog signal utilizing gains. The amplified analog signals are transmitted to analog-to-digital converter circuits. The amplified analog signals are converted to digital signals utilizing the analog-to-digital converter circuits. The digital signals are combined to create a high dynamic range (HDR) image.

A system, method and computer program product for generating an image set for a photographic scene. The method comprises sampling evaluation images comprising an ambient evaluation image and a strobe evaluation image, enumerating exposure requirements for each image comprising the image set, selecting exposure coordinates for each image comprising the image set based on a corresponding exposure requirement and a corresponding evaluation image, generating camera subsystem exposure parameters for each image comprising the image set based on corresponding selected exposure coordinates, storing camera subsystem exposure parameters for each image comprising the image set, sampling each image comprising the image set based on corresponding camera subsystem exposure parameters, and storing each sampled image comprising the image set. Techniques disclosed herein advantageously reduce inter-frame time for images sampled sequentially, and in particular image sets that include both ambient and strobe images.

A technique for generating a digital photograph comprises blending two related images, each sampled according to a different illumination environment. The two related images are blended according to a blend surface function that includes a height discontinuity separating two different blend weight regions. Color consistency between the two related images is achieved by spatial color correction prior to blending. The technique enables a digital camera to generate a strobe image having an appearance of consistent color despite discordant strobe and ambient scene illumination.

A system, method, and computer program product for generating a digital image is disclosed. In use, a first image and a second image are received from a first image sensor, where the first image sensor detects wavelengths of a visible spectrum. A third image and a fourth image are received from a second image sensor, where the second image sensor detects wavelengths of a non-visible spectrum. Using an image processing module, a resulting image is generated by combining one of the first image or the second image, with one of the third image or the fourth image.

A system, method, and computer program product for generating a resulting image from a set of images is disclosed. The method comprises receiving an image set that includes a first image of a photographic scene based on a first set of sampling parameters and a second image of the photographic scene based on a second set of sampling parameters, and generating a resulting image based on the first image and the second image according to depth values in a selection depth map. Each distinct depth value in the selection depth map corresponds to a different image in the image set.
