摘要： An image reading apparatus compensates inter-deviations of and a change in a color temperature of a light source while compensating a difference in the sensitivities between linear image sensors and a change in the sensitivity difference. Three linear image sensors for R, G and B of a multi-line linear image sensor read white reference image data, and a line memory stores the image data. A CPU controls an output state of each second timing signal within a timing generator line by line and independently of a first timing signal, in such a manner that peak values of the white reference image data for three lines stored in the line memory each belong to a predetermined appropriate range. This optimizes a charge accumulating time within each linear image sensor, whereby an RGB balance becomes even at an output side of each linear image sensor.

摘要： Color film scanning apparatus employs a novel trilinear array image sensor with photosites spaced apart in the linear direction of array by a pitch which is a multiple of the photosite dimension in the linear direction. The resultant scanning apparatus allows positioning of the image sensor in close proximity to the film without the need for interposition of optics for beam splitting or image focusing on the sensor arrays.

摘要： There is disclosed an image pickup device comprising plural picture elements, each including plural pixels arranged in the longitudinal direction of the image sensor, wherein the picture elements are so arranged that the separating area between the picture elements has a width larger than the distance between the centers of the pixels mutually adjacent within the picture element. Such arrangement enables high-quality image taking without generation of colored moiree fringes or false colors.

摘要： A sensor assembly (104) and an optical image color scanner using the sensor assembly. The sensor assembly is of the type having three separate rows (112, 114, 116) of optical sensors (200, 202, 204). Two (112, 116) of the three sensor rows have color filters and one (114) is unfiltered (receptive to white light). For gray scale scanning, only the unfiltered (white) (114) 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 (302, 304, 306) 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（104）和使用传感器组件的光学图像彩色扫描仪。传感器组件具有光学传感器（200,202,204）的三个独立行（112,114,116）的类型。三个传感器行中的两个（112,116）具有滤色器，一个（114）未过滤（接受白光）。对于灰度扫描，仅使用未过滤（白色）（114）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缓冲器（302,304,306）。为了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光器（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 motion picture film scanner generates a high definition television signal from the combination of a high definition detail component and a plurality of lower definition color components. The detail component is obtained from a luminance signal generated by a linear array sensor (44) having a line resolution suitable for high definition scanning. The lower definition color components are obtained from three low resolution linear array sensors (36r, 36g, 36b) producing unsharp red, green and blue signals. The luminance array is divided into like-sized segments (44a, 44b, 44c, 44d); multiple registers (48a, 48b, 48c, 48d) are then used to reach the data rate required for high definition scanning. The color photosites are larger than the luminance photosites for improved signal-to-noise performance. By further selecting the number of photosites in each luminance segment to be a submultiple of the number of photosites in a color array, a common clock signal (42) is used to read out all the linear arrays. Plural lines of luminance are thus output for each line of color, thus yielding lower resolution in the vertical as well as the horizontal scanning direction.

摘要： A color scan array (10) for linear imaging employing a matrix of photo-sensor (28) and thin-film transistor (TFT) (29) elements aligned in parallel rows, with each row representing the same color and sub-pixels of a linear array of pixels. The rows of sub-pixels are sub-divided into groups, with the TFT of each color group commonly connected (50) to a data line (D), and with plural gate lines (57) provided each connected to the corresponding TFTs of the sub-pixels of each group pixel. The result is a short, compact sensor with a relatively small number of crossings, and thus with reduced capacitance and increased responsivity.
