Abstract: An imaging apparatus includes an imaging device, a readout unit, and a correction unit. The readout unit performs a first reading operation of reading out a first signal corresponding to accumulated electric charge on a pixel included in a first area of the imaging device, and performs a second reading operation of reading out a second signal corresponding to accumulated electric charge on a pixel included in a second area different from the first area. The correction unit corrects image signals based on signals obtained from the first and second areas by use of neighboring image signals obtained from neighboring pixels located near a pixel targeted for the correction process, and coefficients corresponding respectively to the neighboring pixels. The correction unit sets a coefficient corresponding to each of the neighboring pixels in accordance with the first or second reading operation executed on a neighboring pixel of the neighboring pixels.

Abstract: An image capture apparatus includes an imaging element, first and second setting units, and a reading unit. The imaging element includes a plurality of pixels configured to have a plurality of photoelectric conversion units for one micro lens. The first setting unit sets a first region and a second region. The second setting unit sets a distance measurement region. The reading unit performs different readout operations in the first region and the second region. At the time of capturing images in a plurality of frames, when the second setting unit sets the same distance measurement region in the images in the plurality of frames, the first setting unit changes the position of the first region in the distance measurement region between the images in the plurality of frames at random or periodically.

Abstract: Upper end edges (7a, 7b, 7c) of positioning reference portions (5a, 5b, 5c) to be formed on outer walls of a funnel (1) for cathode ray tube are formed at distances (downwardly) toward a narrow open end (3) of the funnel from a maximum profile line (4) formed in the vicinity of a wide open end (2) by mold matching of forming mold at the time of press molding, thereby suppressing molding defects such as deficiency and wrinkle resulting from that glass is not completely filled, which are likely to occur in reference surfaces (6a, 6b, 6c) of the positioning reference portions, and eliminating occurrences of small cracks caused by concentration of heat stress, which are likely to occur in the upper end edges (7a, 7b, 7c) of the reference portions, to improve the productivity of the funnel.

Abstract: Upper end edges (7a, 7b, 7c) of positioning reference portions (5a, 5b, 5c) are formed on the outer walls of a funnel (1) for cathode ray tube at distances (downwardly) toward a narrow open end (3) of the funnel from a maximum profile line (4), which is formed in the vicinity of or on a wide open end (2). Thus, molding defects such as deficiency and wrinkle resulting from insufficient filling of glass can be avoided, which are likely to occur in reference surfaces (6a, 6b, 6c) of the positioning reference portions. The present invention eliminates occurrences of small cracks caused by concentration of heat stress, to improve the productivity of the funnel.

Abstract: A funnel for a color cathode ray tube comprises a seal end surface to which a panel is sealed through a frit glass. An area occupying at least 50% of the seal end surface in a width direction is a rough surface. The rough surface satisfies conditions of 10?Rz?25 ?m and 2.5<Sm/Rz?6.0, where Rz is the ten point height of roughness profile in the width direction and Sm is the mean interval of profile peaks and profile valleys in the width direction. The rough surface comprises a plurality of dimple-like micro cavities formed by the profile peaks and the profile valleys.
