摘要： Method and apparatus for preparing and displaying images uses image characteristics of an area of interest of images to optimize or otherwise determine image characteristics of the entire image to be displayed. The area of interest information may be used in computing a System Synchronized Backlight Control (“SSBC”) profile for the area of interest, and the SSBC profile may be used to adjust the image signal to provide an image in which the image characteristics, e.g., are optimized for the image at the area of interest. The image characteristics and/or SSBC profile information may be provided as metadata included in a video signal data stream. The area of interest may be selected where the image is obtained, where the image is shown or elsewhere, e.g., in an image storage device, image player, etc.

摘要： Provided is a method of calculating a compensation factor to compensate for lens shading due to the characteristics of an image capturing device, which requires a small amount of memory. A reference image is captured, and a compensation factor is calculated using the characteristics of a lens shading pattern of the captured reference image. A distribution of pixel values is approximated using an exponential spline function, and a compensation factor is calculated using the approximated distribution. In addition, a method and an apparatus for compensating for lens shading by using a calculated compensation factor are provided.

摘要： An analog signal chain for a CMOS active pixel sensor imaging system utilizes, for each amplification stage, a plurality of fixed gain amplifiers instead of a single multi-gain amplifier. The fixed gain amplifier corresponding to the desired gain level is selected and powered on and coupled to the input/output signal paths, while the non-selected fixed gain amplifier(s) are powered off and isolated from the input/output signal paths. Each fixed gain amplifier is operated at a gain bandwidth corresponding to the timing requirements of the imaging system and the gain of the amplifier. Thus, each fixed gain amplifier (other than the one corresponding to the maximum gain of a comparable multi-gain amplifier) operates at a lower level of power consumption than the comparable multi-gain amplifier.

摘要： An A/D converter 11 performs multiple-times sampling on a first signal S1 in a first period T1 while performing multiple-times sampling on a second signal S2 in a second period T2. An A/D converter circuit 17 provides a digital signal in response to a signal from an output 15b of a gain stage 15 in the second period T2. The digital signal may have a value “1” or a value “0”. The A/D converter circuit 17 includes a circuit 18 providing a signal SA/DM corresponding to the number of times the value “1” appears. A switch 24 operates in response to a clock signal φs and is used to sample a signal from a pixel 2a. In a first capacitor circuit 27, a switch 29 and a capacitor 31 are connected to an inverting input 23a and a non-inverting output 23b, respectively. The switch 29 operates in response to a clock signal φ3 and is used for integration in the capacitor 31.

摘要： An image processing method, applicable to a digital image device, includes the following steps. At least one original image of different brightness ranges is captured, and more images of different brightness ranges are generated from the original image by using an image post-processing technique. Based on characteristics of the image of each brightness range, the weights of the image of each brightness range are defined. Then, hierarchical fusion is performed on the images of the different brightness ranges according to weight relations, so as to form a high-dynamic-range image capable of presenting features of each brightness range.

摘要： An imaging apparatus includes an image sensor configured to capture an object image, a selection unit configured to automatically select a sensitivity of the image sensor from a predetermined selectable range, and an image processing unit configured to execute correction processing in which a signal of an image captured by the image sensor which has the sensitivity selected by the selection unit is amplified. When the image processing unit is set to execute the correction processing, the selection unit sets an upper limit of the selectable range lower, compared with the upper limit thereof when the image processing unit is not set to execute the correction processing.
