Patent number: 9185310Abstract: According to one embodiment, a solid-state imaging device includes an illuminance value calculating unit and an illuminance value output unit. The illuminance value calculating unit calculates an illuminance value based on an integration result of luminance values. The illuminance value output unit outputs the illuminance value calculated by the illuminance value calculating unit by setting, as a target, a subject image obtained through application of one of two or more illuminance measurement conditions. The two or more illuminance measurement conditions are set in advance by varying at least one of an electronic shutter time and an analog gain.Type: GrantFiled: January 30, 2013Date of Patent: November 10, 2015Assignee: Kabushiki Kaisha ToshibaInventors: Teppei Nakano, Keizo Tashiro, Junichi Hosokawa, Naoto Mihara

Patent number: 9007487Abstract: According to one embodiment, a camera module has an exposure control unit. When an exposure error has reached within a coring range by first exposure control, the exposure control unit switches exposure control from the first exposure control to second exposure control. The exposure error shows a deviation of an exposure evaluation value to an exposure target value. In the second exposure control, an exposure change amount is reduced than at the time of the first exposure control. When the exposure error has reached a zero level by the second exposure control, the exposure control unit stops the exposure control.Type: GrantFiled: February 6, 2013Date of Patent: April 14, 2015Assignee: Kabushiki Kaisha ToshibaInventors: You Yoshioka, Naoto Mihara, Junichi Hosokawa
