An image processing device that realizes local dimming control and push-up control of a display device using an artificial intelligence function is provided. The image processing device includes a trained neural network model that estimates a local dimming pattern representing light emitting states of light source units corresponding to a plurality of areas divided from a display area of an image display unit for a target display image, and a control unit that controls the light emitting states of the light source units on the basis of the local dimming pattern estimated by the trained neural network model for the target display image displayed on the image display unit.

A display processing system including: a state display unit which displays, for a plurality of parameters each having an upper limit value, a state value of each parameter for a predetermined period of time with respect to the upper limit value; a determination unit which determines, for each of the parameters, whether the state value is close to the upper limit value or not; a warning display unit which displays a warning to a user with regard to a parameter of which the state value is determined by the determination unit to be close to the upper limit value; and a countermeasure display unit which displays, for each of the parameters, a countermeasure for improving the state when the state value is close to the upper limit value.

Display processing system, display processing method, and program

A display control apparatus may include a necessary light emission level calculation unit that calculates a necessary attention block light emission level of a back light in an attention block which satisfies a necessary luminance based on an image signal. A first neighborhood block light emission level calculation unit may calculate a light emission level of first neighborhood blocks which satisfies a deficient luminance by a light emission contribution amount to the attention block through light emission in first neighborhood blocks of the attention block which satisfies the deficient luminance by the back light in the attention block. The back light in the attention block emits the light at the largest light emission level at which the light can be emitted and back lights in the first neighborhood blocks emit the light at the first neighborhood block light emission level.

Display control apparatus and method, and program

The present invention relates to a display control apparatus and method, and a program that are capable of appropriately controlling the luminance of light to be emitted by backlights with simple processing. On the basis of an input image signal, a peripheral-representative-value computation unit () computes, as a peripheral representative value, luminance that is output by backlights of a block of interest and blocks in the periphery thereof among the backlights formed from a plurality of blocks. A peripheral-contribution-amount computation unit () divides the peripheral representative value by light-emission efficiency based on a light-emission profile that is an output luminance distribution when the block of interest emits light so as to compute the amount of peripheral contribution by peripheral blocks to the block of interest. A light-emission level computation unit () computes the backlight luminance as a light-emission level by dividing a necessary amount of light emission of the block of interest by the amount of peripheral contribution. The present invention can be applied to a display device, such as a liquid-crystal display.

The present invention relates to a display control apparatus and method, and a program which make it possible to prevent deterioration in image quality due to insufficient luminance of light from a backlight. A backlight luminance calculating section () finds the backlight luminance of light to be radiated by a backlight, on the basis of the image signal of a display image. A moving image determining section () determines whether or not the display image is a moving image on the basis of the image signal. A correction value calculating section () increases the last correction value by a predetermined value to obtain a new correction value when the display image is a moving image, and decreases the last correction value by a predetermined value to obtain a new correction value when the display image is a still image. An addition section () adds the correction value to the backlight luminance to correct the backlight luminance. The present invention can be applied to a liquid crystal display apparatus.

The present invention relates to a display control apparatus and method, and a program which make it possible to suppress deterioration in the image quality of an image. A backlight luminance calculating section () finds the backlight luminance of light to be radiated by a backlight, on the basis of the image signal of an image. A subtraction section () finds the difference between the backlight luminance from the backlight luminance calculating section (), and a backlight luminance from an addition section (). A multiplication section () multiplies the found difference by a cyclic coefficient indicating the degree of contribution of the difference to correction of the backlight luminance, obtaining a correction value. The addition section () adds the correction value to the backlight luminance to correct the backlight luminance. Also, from the image signal and the backlight luminance, a division section () calculates the transmittance of light in a liquid crystal panel that displays an image by transmitting light from the backlight. The present invention can be applied to a liquid crystal display apparatus.

In an image processing apparatus that performs image processing on an image supplied from an imaging apparatus that captured an original image and that performed gamma processing on the original image to generate the image to be supplied to the image processing apparatus, inverse gamma processing means performs inverse gamma processing on the image supplied from the imaging apparatus so that the image has characteristics the same as characteristics of the original image, which corresponds to the image before the image was subjected to the gamma processing in the imaging apparatus, and correction processing means performs correction processing on the image subjected to the inverse gamma processing using the inverse gamma processing means so that blur in the image is corrected.
