A correction value for luminance correction is determined by: measuring a luminance value of each of display elements by displaying a first image including luminance unevenness caused by characteristic differences among the display elements and characteristic differences among modulation circuits, and calculating a first luminance value serving as a representative luminance value of the display elements for each of the modulation circuits; measuring the luminance value of each of the display elements by displaying a second image in which the luminance unevenness caused by characteristic differences among the modulation circuits is smaller than that of the first image, and calculating a second luminance value serving as a representative luminance value of the display elements for each of the modulation circuits; and calculating a correction value corresponding to each modulation circuit using a value obtained by dividing the first luminance value by the second luminance value.

A first step drives a plurality of electron-emitting devices with a drive signal corresponding to a first gradation level and measures the luminance dispersion. A second step selects one or more electron-emitting devices as target devices, drives them with a drive signal corresponding to each gradation level, and measures their luminance for each gradation level. A third step drives the target devices with a drive signal having a voltage amplitude of a drive signal corresponding to each gradation level multiplied by a constant, and measures their luminance for each gradation level. Then, a correction value for each gradation level of each electron-emitting device is calculated using a luminance ratio of the luminance measured in the second step to the luminance measured in the third step, and the luminance dispersion measured in the first step.

An optical coherence tomography apparatus includes a light source for generating a low-coherent light beam, which is split into a probe light beam toward the object and a reference light beam toward a reference optical path. The probe light beam is swept one-dimensionally at a predetermined frequency. An interference light beam is produced by interference between the probe light beam from the object and the reference light beam that has traveled along the reference optical path. The interference light beam is re-swept in the same direction and at the same frequency as the probe light beam. A two-dimensional image-capturing device detects the re-swept interference light beam at a frame rate corresponding to the light beam sweeping frequency and produces a video signal, which is processed to provide reflection intensity information of an interior of an object to be measured. Since the two-dimensional image-capturing means is employed and interference information is obtained using low-speed beam sweeping and re-sweeping means, a scanning optical system can be straightforwardly constructed.

When a source program written in Java or the like and using methods of BigDecimal class, a priority conforming to a predetermined arithmetic rule is identified for an arithmetic operational method included in an arithmetic operation statement, and the arithmetic operational method and the identified priority are registered into a storage device. Then, in a case where it is judged based on data stored in the storage device that a plurality of arithmetic operational methods are included in an arithmetic operational statement, and an arithmetic operational method with low priority is defined as an instance of an arithmetic operational method with high priority, following processing is carried out to generate specification data, that is, the arithmetic operational method with low priority and an instance and argument of the arithmetic operational method with low priority are converted into a first subexpression using an arithmetic operational sign in accordance with a predetermined rule. Then, parentheses representing that the arithmetic operation are carried out with priority is added to the first subexpression. In addition, the arithmetic operational method with high priority and an argument of the arithmetic operational method with high priority are converted into a second subexpression using an arithmetic operational sign in accordance with the predetermined rule. Finally, the second subexpression is linked with the first subexpression.

A digital still camera records image data by picking up an image of an object. One mode is set among plural photographing modes including a standard photographing mode and a portrait mode adapted to an image containing an abrupt change in gradation. An optimized exposure amount is acquired according to brightness derived from the image data. When the portrait mode is set, portrait mode image data is acquired by setting exposure lower than the optimized exposure amount. The image data is processed in gradation conversion by use of first or second gamma conversion table. The first gamma conversion table is used for the standard photographing mode. The second gamma conversion table is used for the portrait mode, predetermined to extend a dynamic range of the image data after the gradation conversion in comparison with the first gamma conversion table, to process the portrait mode image data in gradation conversion.

A plurality of images (I, J) of an object (M) when viewed from different viewpoints are taken in. One of the images is set as a standard image (I), and the other image is set as a reference image (J). One-dimensional pixel data strings with a predetermined width (W) are cut out from the standard image (I) and the reference image (J) along epipolar lines (EP1, EP2) calculated from a camera parameter (CPR) and the reference point (p). Calculating a phase-only correlation function from the cut one-dimensional pixel data strings will obtain a correlation peak position (Pa1). A positional shift amount (d) from the correlation peak position (Pa1) is obtained. A search is made for a corresponding point (q) corresponding to the reference point (p) based on this position shift amount (d).

An edge amount detector detects an edge amount from RGB signals, and a filter processor synthesizes an output for edge enhancement with an output for smoothing at a proportion based on the detected edge amount. Another edge amount detector detects an edge amount of a black component from CMY signals, and an ink generator/undercolor remover changes an ink generation rate according to the detected edge amount.

The user instructs a server apparatus to display thumbnails in a list. When an instruction for displaying the list is received at the server apparatus, a display screen control processing unit generates a thumbnail list display screen and transmits it to a client apparatus. The user browses the display screen and issues an instruction for changing a display magnification. The instruction is transmitted to the server apparatus as screen control data. The server apparatus changes a thumbnail list view screen in accordance with the screen control data and displays it on the display screen.
