An image forming apparatus has an image acquisition portion that acquires image data on an image including a character. A character-periphery detector detects the peripheral part of the character in the image data acquired by the image acquisition portion. An outline emphasis portion sets the density of the image data acquired by the image acquisition portion, so that the density of the peripheral part of the character detected by the character-periphery detector becomes higher than the density indicated by this image data. A density changer sets the density of the image data so that this density gradually becomes lower from the peripheral part of the character detected by the character-periphery detector toward the inside thereof. An image former forms an image on a sheet of recording paper on the basis of the image data whose density is set by the outline emphasis portion and the density changer.

A signal processing apparatus comprising: an analog-digital converter that converts an analog signal output from a pixel section of an image sensor to a digital signal using a plurality of reference signals having different slopes from each other; and a determination unit that determines a signal level at which the plurality of reference signals are changed based on a distribution of the converted digital signal, wherein the analog-digital converter performs the conversion using a reference signal having a steeper slope when the analog signal is equal to or greater than the signal level than when the analog signal is smaller than the signal level.

In a head-mounted display for presenting a video by shielding an outside world from a field of view of a user when mounted on the user, an information presentation block presents information including audio and a moving image to the field of view of the user; a video reproduction block reproduces a video of content; a camera takes a video of the outside world; a switching block selectively switches between the video of the content and the video of the outside world and causes the selected video to be presented onto the information presentation block; and a gain control block, when the switching block switches from the video of the content to the video of the outside world, gradually increases a brightness of the video of the outside world.

A digital camera includes an imaging section, an overlapping area identifying section, a feature point judging section, a luminance adjusting section, and an image combining section. The overlapping area identifying section identifies overlapping areas of images consecutively captured by the imaging section. The feature point judging section judges whether amount of texture within areas of a predetermined range in the identified overlapping areas is larger or smaller than a predetermined reference value. The luminance adjusting section adjusts the pixel values of the images so that the pixel values of the overlapping areas come within a predetermined range, based on a judgment result of the texture. The image combining section combines the adjusted images such that their overlapping areas coincide with each other.

The object is to provide a uniform impression of noise for an entire image signal by performing grayscale conversion and noise reduction in a balanced manner. The signal processing unit performs first signal conversion on an image signal from an image-acquisition device and transfers the processed image signal to a correction-coefficient calculation unit. The correction-coefficient calculation unit calculates, on the basis of the image signal from the signal processing unit, an area correction coefficient for each area used for grayscale conversion of each area. A noise reducing unit uses the area correction coefficients calculated by the correction-coefficient calculation unit to perform noise reduction on the image signal from the image-acquisition device and transfers the processed signal to the signal processing unit. The signal processing unit performs grayscale conversion on the areas of the noise-reduced image signal and transfers the signal to the compressing unit using the area correction coefficients.

A parameter of a consumption item (fuel, life) consumed as a game progresses is calculated. When a setting of a game termination condition changes, a rate of change of the parameter of the consumption item is changed according to the change of the setting. The game termination condition is a condition relating to the number of laps on a course, a time limit of a game or a game quota. The rate of change of the parameter of the consumption item is increased as the number of laps on a course is reduced, as the time limit of a game is shortened, or as the game quota is reduced. When a value of the parameter of the consumption item becomes equal to zero as a game progresses, the movement or motion of an object is disabled. The parameter of the consumption item is changed from an initial value set by a player with the rate of change which has been specified based on the game termination condition set by the player.

The invention discloses a high-naturalness real-time beautifying method and device, and the method comprises the steps: employing a single-channel high-contrast image buffing method which employs the channel with the smallest number of interference noise points in three channels r, g and b, and effectively reduces the noise interference from other channels while reducing the calculation amount; obtaining the roughness information of skin through calculating a single-channel high-contrast image buffing image, thereby avoiding the skin distortion caused by the direct filtering of the image, and improving the naturalness of skin; and employing a layer mixing and overlapping method: employing a method of filtering, light softening and brightening mixing and overlapping to achieve an effect of skin buffing and whitening and to maintain the naturalness of the image after a buffing layer is calculated and obtained.
