Abstract: Provided is a device adapted for detecting chemical and physical phenomena and suitable for high integration, and a method for controlling the detection device. When a plurality of pH-detecting devices are used, a variation in sensitivity occurs in each of the sensing units. The variation in sensitivity can be calibrated using a simple method. The amount of charge (output signal) delivered by each of the sensing units to a standard solution is determined, and the difference between the delivered charge amount and a standard charge amount (standard output signal) delivered by a standard sensing unit is determined. The capacity of the potential well of the sensing unit is changed, or the potential of a TG unit when a charge is delivered is changed, so as to cancel out the difference.

Abstract: A combined detector capable of simultaneously detecting both a value indicating a physical/chemical phenomenon such as a pH value and the intensity of an energy beam such as light. The combined detector comprises a physical/chemical phenomenon detecting system (10) and an energy beam detecting system. The physical/chemical phenomenon detecting system (10) has a sensing section (21) whose potential varies with a physical/chemical phenomenon, a charge supply section (22) for supplying first charge to the sensing section, a charge supply control section (23) provided between the sensing section (21) and the charge supply section (22), a first charge storage section (26) for storing the first charge transferred from the sensing section (21), and a charge transfer control section (27) provided between the sensing section (21) and the first charge storage section (26).

Abstract: A spectroscopic device with high sensitivity is provided. A spectroscopic device has a charge generating section 3 for generating a charge by using an incident light, a charge generation controlling section for controlling the charge generating section 3 between a first state for capturing a charge generated in a range from a surface to a first depth of the charge generating section 3 and a second state for capturing a charge generated in a range from the surface to a second depth of the charge generating section 3, and a floating diffusion section 2 for outputting a signal corresponding to a charge quantity captured by the charge generating section 3. In the spectroscopic device, the charge capturing depth W in the charge generating section 3 is controlled by controlling the lowest potential Vc of the charge C filled in a charge well 105 of the charge generating section 3.

Abstract: When composition of a first captured image having a tilted subject image is corrected, the first image is rotated such that the subject image stands in an erect position, according to the attitude of the camera achieved during capture of the first image. Images corresponding to missing portions, which arise in the image area for recording due to rotation, are extracted from a second captured image as compensation images. The second image is obtained by capturing an image of the same subject as that captured by the first image, at the different angle of view and attitude of the camera. An image obtained by enlarging the compensation images extracted from the second image according to the angle of view employed for capturing the first image is synthesized with the rotated first image, to thus make the subject image stand in an erect position and to obtain a corrected image without involving a decreased number of pixels.
