    摘要: A delay control apparatus includes first and second delay elements each configured to receive and delay a strobe signal and clock by a prescribed delay value. A prescribed number of flip-flops is provided to input data upon receiving the strobe signal output from the second delay element. The second delay element delays and outputs the strobe signal by the prescribed delay value to the flip-flops when the selection device selects the strobe signal. A phase comparator compares clocks output from the first and second delay elements. A delay control device changes the prescribed delay value of the second delay element in accordance with the comparison result of the phase comparator when the selection device selects the clock.

    摘要: A character table unit stores as attribute data of each character of an image a character name, a horizontal direction character size, a vertical direction character size, a horizontal display coordinate value and, a vertical display coordinate. A counter outputs count values indicating a horizontal position and a vertical position in a display screen image. A first writing control unit reads from the character table unit the attribute data of an appropriate character based on the count values of the counter and the attribute data, produces basic size attribute data of basic size characters which constitute at least part of the character. The basic size character is determined to be currently displayed based on the count values. The basic size character attribute data is written in a hit buffer. A image data memory stores character image data. A second writing control unit reads basic size attribute data from the hit buffer, producing addresses based on the basic size attribute data to read character image data from the image data memory, and writing the character image data into a line buffer. Image data is read from the line buffer, in synchronization with the count value indicating a current horizontal position.

    摘要: First to fourth lenses are aligned in an optical axis direction by a lens-barrel of a camera, an O-ring is disposed between the first lens and the lens-barrel, an O-ring is disposed between the fourth lens and the lens-barrel, a space is formed between the first and second lenses, a space is formed between the second and fourth lenses, a space is formed between the third and fourth lenses, and flow of air between the spaces is precluded. The camera thus configured is free of dewing on the lens or a protective plate exposed to the exterior, even when the inside temperature is raised due to heat generation in a CCD or a mounting substrate on which the CCD is mounted.
