A solid-state imaging device is provided and has: three photoelectric conversion layers stacked above a semiconductor substrate, each detecting a different color; three signal charge accumulators in a semiconductor substrate for accumulating signal charges generated in each of the three photoelectric conversion layers: and a signal readout circuit in the semiconductor substrate for reading out signals corresponding to the signal charges accumulated in the signal charge accumulators. The three signal charge accumulators are arranged in a direction in the surface of the semiconductor substrate as a pixel and a plurality of the pixels are arranged in a square lattice pattern both in the direction and a direction perpendicular thereto. The three signal charge accumulators arranged in each pixel in an odd row are arranged such that an array of the signal charge accumulators in the first sub-row of each pixel has all of the three signal charge accumulators.

A mounting board of a camera module of a mobile phone is screwed to an outer cover through cushions formed of rubber, sponge or the like. A solid state imaging device and an optical unit of the camera module are contained in an opening formed in the outer cover and do not contact the outer cover. The mounting board is connected to a main substrate through a flexible board. Accordingly, even if the mobile phone is dropped down, the camera module is prevented from breakage by the vibration or the shock applied to the mobile phone, because the vibration and the shock are not transmitted to the camera module directly.

A mounting board has a thickness Lbeing thicker than a thickness Lof a solid state imaging device. In the mounting board, an attachment opening for containing the solid state imaging device is formed. In addition, a side surface of the solid state imaging device is a tapered surface having an inclination angle &#x3b8;, and an internal surface of the attachment opening is a tapered surface having an inclination angle &#x3b8;larger than the inclination angle &#x3b8;. On the side surface of the solid state imaging device and the internal surface of the attachment opening respectively, contact terminals are provided for electrically connecting the solid state imaging device and the mounting board, when the contact terminals contact each other according to insertion of the solid state imaging device into the attachment opening.

A zener diode is formed in a spacer, which adhered on the semiconductor substrate so as to surround an image sensor, by semiconductor process. A first contact terminal is connected to a CCD output terminal of the image sensor, and a second contact terminal is connected to a ZD ground terminal on the semiconductor substrate. When the ZD ground terminal is connected to ground, the zener diode is actuated. Capacitance components of the zener diode smoothes a waveform of the CCD output so as to prevent an unnecessary radiation noise from generating.

A solid state imaging device is constituted of an image sensor chip, a circuit board, and an electromagnetic-wave absorber formed of copper. The image sensor chip is constituted of a bare chip, a spacer, and a cover glass. First contact terminals are formed on the bare chip, and second contact terminals and GND wires are formed on the circuit board. When manufacturing, the image sensor chip is mounted at a predetermined position on the circuit board, and the first contact terminals and the second contact terminals are connected with bonding wires. The electromagnetic-wave absorber is formed to cover the bonding wires, while its end contacts to the GND wires.

The level of smear charge stored in a CCD is calculated. If the smear level is equal to or greater than a predetermined threshold value, exposure is performed using a mechanical shutter in order to suppress smear. If the smear level is less than the threshold value, exposure is controlled utilizing an electronic shutter. Power consumption owing to drive of the mechanical shutter can be reduced while occurrence of smear is suppressed.

In a solid-state image pickup apparatus, an image pickup section includes a color separating section having color filters assigned to three primary colors for separating colors of light incident from a desired scene. The color filters assigned to the color G are arranged in stripes. A system controller controls an output of a drive signal generating section for each of an all pixel read mode and a photometry control mode in response to the stroke of a shutter release operation. In the photometry control mode, the image pickup device is supplied with drive signals in response to a horizontal timing signal fed from a timing signal generator and a control signal fed from the system controller. The image pickup device thus reads out only the signal charges representative of the color G in this mode, thereby especially implementing the signal charge reading at a doubled speed.
