An image processing device and method, a program, and a recording medium whereby the detection precision of a motion vector by the gradient method is further improved. A counter value computing unit acquires the number of valid pixels, the number of pixels having no gradient in the horizontal direction, and the number of pixels having no gradient in the vertical direction from a valid pixel number counter, a no-horizontal-gradient counter, and a no-vertical-gradient counter, computes the ratio between valid pixels within a computation block and one-sided gradient pixels among the valid pixels, and controls the value of a flag which a flag setting unit sets in accordance with the computation results. The flag setting unit sets the value of a gradient flag, and outputs the gradient flag to the subsequent stage. At the subsequent stage, gradient method computation and vector evaluation processing are executed based on the gradient flag. The above can be applied to a signal processing device for performing frame frequency conversion processing from a 24P signal to a 60P signal.

The present invention relates to data structures, image processing apparatuses, image processing methods, and programs for enabling appropriate processing of video data of 3D content.Obtained content data of 3D content contains video data of 3D images, and information about a reference image size, which is a predetermined image size serving as the reference for the 3D images, and the maximum and minimum parallaxes for the reference image size. An image size detecting unit (71) detects the image size of the video data of the 3D images. If the detected image size of the 3D video data is not the same as the “reference image size,” a maximum/minimum parallax calculating unit (72) calculates the maximum and minimum parallaxes corresponding to the image size of the 3D video data. A caption adjusting unit (73) performs predetermined image processing based on the calculated maximum and minimum parallaxes, such as processing to adjust the depth positions of captions. The present invention can be applied to an image processing apparatus that processes obtained image data of 3D images, for example.

An image processing apparatus includes a first acquiring unit, a second acquiring unit, and a correction processor. The first acquiring unit acquires an intended viewing environment parameter, which is a parameter of an intended viewing environment, together with image data of a three-dimensional picture. The second acquiring unit acquires an actual viewing environment parameter, which is a parameter of an actual viewing environment for a user viewing the three-dimensional picture. The correction processor corrects the three-dimensional picture in accordance with a difference between the acquired intended viewing environment parameter and the acquired actual viewing environment parameter.

An image data processing apparatus is provided and includes a variable length decoding section to decode and extract quantized DCT coefficients from an encoded signal input thereto and extract encoded information from side information added to the encoded signal. Classification adaptation processing sections use the input signal supplied from a decoding section and a creation signal supplied from a signal storage section to determine the reliability of each of motion compensating vectors of the encoded signal supplied from a coded information storage section, selects that one of the motion compensating vectors which has the highest reliability as a selected vector, and produces a creation signal based on the selection vector.

JPEG encoded data are entropy-decoded to quantized DCT coefficients which are sent to a prediction tap extraction circuit (41) and to a class tap extraction circuit (42). The prediction tap extraction circuit (41) and the class tap extraction circuit (42) extract what is needed from the quantized DCT coefficients to form prediction taps and class taps. A classification circuit (43) effects classification based on the class taps. A coefficient table storage unit (44) sends tap coefficients corresponding to the classes resulting from the classification to a sum of products circuit (45), which sum of products circuit (45) then effects linear predictive calculations, using the tap coefficients and the class taps, to generate decoded picture data.

To reduce burden of a viewer at the time of performing stereoscopic display by a stereoscopic display device and to show a stereoscopic image in a natural and comfortable manner.A disparity estimating unit 210 estimates disparity from the left and right images of an input image to generate a disparity map. A disparity analyzing unit 230 analyzes the disparity map to generate a disparity control parameter for performing suitable disparity control. A disparity control unit 240 controls the content of processing at an image conversion unit 250 in accordance with the disparity control parameter. The image conversion unit 250 performs image conversion on the input image based on the control by the disparity control unit 240 to output an output image. The image conversion unit 250 performs image conversion of two steps. The image conversion unit 250 performs shift processing for shifting the relative positions of the left and right images of the input image in the horizontal direction as first step image conversion, for example. The image conversion unit 250 performs scaling processing for performing enlargement/reduction of the entire screen with each center of the left and right images as a reference, as second step image conversion, for example.
