摘要： Areas of a video signal that represent light emission are detected, the luminance levels at which said light emission areas are displayed are enhanced, emphasizing the areas, and the luminance stretching is controlled in accordance with the brightness of the surrounding environment, thereby increasing the resulting sense of brightness and improving the appearance of the video. A light emission detector counts pixels to generate a histogram of a prescribed feature quantity and identifies areas that fall within a prescribed range at the upper end of said histogram as being light emission areas. An area-active-control/luminance-stretching portion performs luminance stretching, increasing the luminance of a backlight portion and reducing the luminance of non-light emission areas of the video signal. The area-active-control/luminance-stretching portion switches between control curves, defining the relationship between the brightness-related index and the amount of stretching, in accordance with the brightness of the surroundings of the device.

摘要： A method for displaying arrays of digital image data on a display monitor as a continuous image includes determining nonlinear corrections for each of the arrays of digital image data. Each nonlinear correction may be based in part on a location of the imaging device used to capture the array of digital image data relative to a location of the perspective center from which the array of digital image data will be displayed on the display monitor. The method also includes transforming each array of digital image data using the corresponding nonlinear correction. The method also includes displaying the arrays of corrected image data on the display monitor to produce a continuous display of the scene captured by the imaging device, where relative sizes and positions of objects in the scene are substantially reproduced in the display of the scene.

摘要： An AD converting unit compares an output signal from an amplifier circuit after reset of a pixel with a reference signal of time-variable, outputs a first digital value, when the output signal from the amplifier circuit in a non-reset state of the pixel is larger than a threshold, sets a gain of the amplifier circuit to a first gain, when the output signal is smaller than the threshold, sets the gain of the amplifier circuit to a second gain larger than the first gain, further after the gain of the amplifier circuit was set to the first or second gain, compares the output signal from the amplifier circuit in the non-reset state of the pixel with the reference signal of time-variable, and outputs a second digital value. When resolutions of the first and second digital values differ, a correcting unit corrects a difference between the resolutions.
