摘要： A solid state image pickup apparatus can obtain a constant photoelectric transfer output even if an incident light intensity is very high, so that a signal processing circuit to be connected to an output of the apparatus can be simplified in configuration and only low voltage and low power are required. In the apparatus, an incident light intensity on a photoelectric transfer surface is detected, and a charge stored time is decreased in accordance with an increase in the incident light intensity. When the incident light intensity falls within a normal range, the transfer gate clock pulse is controlled to have a predetermined pulse width so as to allow transfer of the photoelectric transfer charge to the CCD shift register. Thus, a substantially constant photoelectric transfer output can be obtained. When the incident light intensity is high, the pulse width of the transfer gate clock is decreased. When the transfer gate clock pulse is controlled to have a short pulse width in this manner, a substantially constant photoelectric transfer output can be obtained irrespective of the incident light intensity.
摘要翻译：固态图像拾取装置即使入射光强度非常高，也可以获得恒定的光电转移输出，从而能够简化与装置的输出连接的信号处理电路，并且仅能够实现低电压和低功率是必要的。在该装置中，检测光电转移表面上的入射光强度，并且根据入射光强度的增加减少电荷存储时间。当入射光强度落在正常范围内时，传输栅极时钟脉冲被控制为具有预定的脉冲宽度，以便允许将光电转移电荷转移到CCD移位寄存器。因此，可以获得基本上恒定的光电转移输出。当入射光强度高时，传输门时钟的脉冲宽度减小。当以这种方式将传输门脉冲脉冲控制为具有短的脉冲宽度时，可以获得基本恒定的光电转移输出，而与入射光强度无关。

摘要： In an apparatus for detecting the in-focus state of a photo-taking lens of a camera, a defocus signal is produced responsive to a light intensity distribution signal and is indicative of deviation between an image of an object to be photographed and a predetermined surface. An information signal is produced indicative of the effectiveness of the defocus signal. A vignetting detection signal is produced indicative of the state of vegnetting by the photo-taking lens. The information signal is compared with a threshold value to determine the effectiveness of the defocus indicated by the defocus signal, and the threshold value is changed in response to the vignetting detection signal. A photo-taking lens may include a memory that stores data indicating an inverse of a value indicative of a distance from a predetermined plane to an exit pupil of the photo-taking lens, and the data stored in the memory may be used for calculating vignetting.
