摘要： A digital camera simulates the use of fill flash. The camera takes a series of photographs of a scene at various focus distances. The photographs are stored, along with their corresponding focus distances. The photographs are analyzed to determine the distance to objects at various locations of the scene. Regions of a final photograph are selectively adjusted in brightness based on the distance information to simulate the effect that would have resulted had fill flash been used.

摘要： A system and method for color correcting electronically captured input images utilizes a correlation between the input images and a set of reference images of different media types to determine the media type of the input images. In an exemplary embodiment, the correlation is performed using a media correlation matrix, which includes media characteristic data from the different media types. The media type information of the input images is used to customize the color correction procedure being performed on the input images. The customization of the color correction procedure ensures that the final images are accurate reproduction of the input images with respect calorimetric or perceptual match.

摘要： An imaging appliance family is a cooperative system of two or more imaging appliances that are linked together to share images, command and control. Imaging appliances may be linked to each other by introducing the appliances to each other, establishing a communications link, and exchanging appliance information. After communications are established, appliance information is exchanged and the appliances are dynamically configured into a cooperative system. As part of the appliance information exchanged, an address and an associated image are exchanged. The image may be of the imaging appliance, the user or the location of the user or imaging appliance. When selecting another imaging appliance to communicate with, instead of identifying the imaging appliance by descriptive text, the user identifies the imaging appliance according to its identifying image. Thus, each imaging appliance includes a thumbnail associated with it that identifies it to other appliances.

摘要： A digital camera includes a lens and a plurality of color filters adjacent the lens. An array of detectors such as CCDs each receive, through the lens and a corresponding one of the color filters, light reflected from a scene. Each detector outputs a signal representative of an amount of light it receives. Circuitry is connected to the array for processing the signals from the detectors and generating a set of digital image data including a chromaticity value and a luminance value of a plurality of pixels representing an uncorrected image of the scene. A control circuit maps a two-dimensional representation of the digital image data into a two-dimensional representation of a set of reference image data and adjusts selected ones of the values of the set of digital image data in accordance with a predetermined transform to white balance the uncorrected image of the scene and produce a modified set of digital image data representing a corrected image of the scene.

摘要： A sensor assembly and an optical image color scanner using the sensor assembly. The sensor assembly is of the type having three separate rows of optical sensors. Two of the three sensor rows have color filters and one is unfiltered (receptive to white light). For gray scale scanning, only the unfiltered (white) sensor row is used, thereby maximizing the speed of gray scale scanning. For color scanning, three color values are computed as a linear transformation of values from the two filtered and one unfiltered values. The linear transformation may be as simple as subtracting signals from the two filtered sensor rows from the signal from the unfiltered (white) sensor row. For color scanning, memory buffers are required for two of the three sensor output signals. For highest accuracy in color scanning, the exposure time for the white sensor row is reduced relative to the exposure time for the two filtered sensor rows. An optional white channel bandpass filter (passing all wavelengths within the human visual range and rejecting wavelengths outside the human visual range) provides improved accuracy if the light source has significant wavelengths outside the human visual range.
摘要翻译： 传感器组件和使用传感器组件的光学图像彩色扫描仪。 传感器组件是具有三个独立行的光学传感器的类型。 三个传感器行中的两个具有滤色器，一个未过滤（接受白光）。 对于灰度扫描，仅使用未滤波（白色）传感器行，从而最大化灰度扫描的速度。 对于彩色扫描，三个颜色值被计算为来自两个滤波值和一个未滤波值的值的线性变换。 线性变换可以像从未滤波（白色）传感器行的信号中减去来自两个滤波的传感器行的信号一样简单。 对于彩色扫描，三个传感器输出信号中的两个需要存储器缓冲器。 为了获得最高的彩色扫描精度，白色传感器行的曝光时间相对于两个经滤波的传感器行的曝光时间减少。 如果光源在人类视觉范围之外具有显着的波长，则可选的白色通道带通滤波器（通过人类视觉范围内的所有波长并排除人类视觉范围之外的波长）提供了更高的精度。

摘要： A broadband line source that is directional, rugged, compact, spatially and temporally uniform, stable, without the need for warmup, and relatively easy to implement. The source can be in single-color or multi-color, and it can be used, for example, in a scanner. In one embodiment, the line source includes a first thin-film electroluminescent stack with at least a bottom electrode, a top electrode, and a first active film between the two electrodes. The active film generates radiation in an area that has a width and a length, with the length being larger than the width. The length of the area sets the length of the line radiation, which is substantially homogenous along the line. In another embodiment, three of such stacks are encapsulated through thin-film processes by a cap, which sits on a substrate. The cap has one side surface that is more transmissive to radiation. The generated radiation is directed by the cap to be emitted at the more transmissive side surface to produce a single-color or a multi-color line source.

摘要： Systems and methods for testing and calibrating camera modules based on a benchmark standard are provided. The systems can include a receptacle for receiving a camera module under test and a spectrometer. The test station can capture a test measurement using the camera module under test while contemporaneously capturing a true measurement using the spectrometer. Using the true measurement, the test station can predict how the benchmark standard would have performed in those conditions and compare that expected performance to the test measurement. Any differences can be stored in memory within the camera module under test for later retrieval to optimize image processing.
