A thermal medium and a laser recording device are provided in which medium parameters can be acquired efficiently. According to one embodiment, the thermal medium includes a photothermal conversion layer, a color development layer, a storage mechanism. The photothermal conversion layer converts an applied laser beam into heat. The color development layer develops a color by the heat converted by the photothermal conversion layer. The storage mechanism stores information related to a medium parameter including a photothermal conversion efficiency of the photothermal conversion layer.

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.

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.

According to one embodiment, a solid-state imaging device includes a luminance integrating unit, a luminance observation value calculating unit, and an illuminance value conversion unit. The luminance integrating unit integrates a luminance value detected for every pixel. The luminance observation value calculating unit calculates a luminance observation value based on an integration result in the luminance integrating unit. The luminance observation value is an observation result of the luminance for an entire imaging screen. The illuminance value conversion unit converts the luminance observation value to an illuminance value. The luminance integrating unit integrates the luminance value discriminated in accordance with a condition set with respect to a luminance level.
