    • An electronic camera includes an imaging device. The imaging device includes an imaging surface capturing an object scene through a focus lens, and produces an object scene image in a designated cycle. When a shutter button is half-depressed, an adjuster adjusts a position of the focus lens based on the object scene image produced by the imaging device. Also, a determiner determines whether or not both an illuminance and a contrast of the object scene captured by the imaging surface fall below a reference in association with a position adjusting process of the focus lens, and a controller sets a length of the designated cycle when a determination result is affirmative to be longer than that of the designated cycle when the determination result is negative.
    • 电子照相机包括成像装置。 成像装置包括通过聚焦透镜捕获对象场景的成像表面,并且以指定的周期产生对象场景图像。 当半按下快门按钮时,调节器基于由成像装置产生的对象场景图像调节对焦透镜的位置。 此外,确定器确定与成像表面拍摄的对象场景的照度和对比度是否与聚焦透镜的位置调整处理相关联地落在基准之下,并且控制器设定指定周期的长度, 当确定结果为否定时,确定结果肯定比指定循环的确定结果更长。

    • Disclosed is a memory controller which comprises an output-side circuit that includes: a normal-mode phase shift amount control circuit; a test-mode phase shift amount control circuit; a selector for selecting an output from either of the two normal-mode phase shift amount control circuits; and a variable delay circuit for receiving the output of the selector, varying the amount of data of a clock signal and supplying the resultant signal to a data output circuit as a sampling clock; a signal obtained by phase-shifting the clock signal a fixed amount being output as the data strobe signal. The memory controller comprises an input-side circuit that includes: a normal-mode phase shift amount control circuit; a test-mode phase shift amount control circuit; a selector for selecting an output from either of the two normal-mode phase shift amount control circuits; and a variable delay circuit for receiving the output of the selector, varying the amount of data of a clock signal and supplying the resultant signal to a read-data capture circuit as a sampling clock. The memory controller is provided with a first comparator circuit for performing an expected-value comparison between read data looped back and then latched by the read-data capture circuit and write data, and a second comparator for performing an expected-value comparison in a case where sampling timing of input data has been delayed by an amount equivalent to one edge.

    • An electronic camera includes an imager which outputs an object scene image in a designated cycle. The first changer changes a distance from a focus lens to the imaging surface. The first adjustor adjusts the designated cycle to a length corresponding to an illuminance of the object scene in association with a process of the first changer. The first specifier specifies a distance range including a focal point in parallel with the process of the first changer. The second changer changes the distance from the focus lens to the imaging surface in the distance range specified by the first specifier. The second adjustor adjusts the designated cycle to a length corresponding to a contrast of the object scene in association with a process of the second changer. The second specifier specifies the distance corresponding to the focal point in parallel with the process of the second changer.
