Abstract: PURPOSE: A photographing device photographing by suing a rolling shutter is provided to use a contrast AF(Auto Focusing) process even when a subject is not stable, thereby adjusting the focus to the subject. CONSTITUTION: An image sensor(124) outputs an image signal having an electric charge accumulated in a pixel of 1 line. A focusing sensor(131) uses a contrast value of frame image data of a first image frame formed by the image signal and senses a focus fit condition state in the photographing sensor of a subject image. The photographing sensor changes the electric accumulation period. The photographing sensor extends the electric accumulation period in a photographing condition which can predict the movement of a subject.

Abstract: PROBLEM TO BE SOLVED: To obtain an imaging apparatus capable of displaying an image reduced in distortion on a display device even if imaging a subject having a large change.SOLUTION: A CMOS imager 124 outputs an analog image signal by a rolling shutter function for alternately performing scanning from above to below and from below to above on an imaging surface. When imaging a subject in which a state changes at a lapse of time, the state of the subject may change until photodiodes in all rows and columns complete outputting charges. For preventing the changes, when the movement of a subject is larger than a threshold, an analog image signal outputted by scanning from above to below using the CMOS imager 124 is averaged with an analog image signal outputted by scanning from below to above to obtain images reduced in distortion.

Abstract: PROBLEM TO BE SOLVED: To provide an image pickup device capable of properly performing contrast AF even in imaging of a greatly varying object.SOLUTION: When the contrast AF is performed while using a period for reading pixels in two rows as a charge storage period, a period during which the pixels store charge is prolonged as compared with when a period for reading pixels for one row is used as a charge storage period, and an object image is obtained from pixels in the m-1-th row and n-th column, m-1-th row and n+1-th column, m-th row and n-th column, and m-th row and n+1-th column. When the object moves further, the object image is obtained from pixels in the m-th row and n+1-th column, m-th row and n+2-th column, m+1-th row and n+1-th column, and m+1-th row and n+2-th column. Thus, in comparison with scanning carried out immediately before, overlapping of the object image occurs in the n+1-th column. Therefore, correlation of the object image between the read rows is increased. Consequently, deterioration in contrast reliability of the object image in the vertical direction can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To obtain an imager capable of quickly and simply recording a character string desired by a user in an image.
SOLUTION: A sampling part samples a voice of "pretty" through a microphone. The sampling part converts the voice into a digital sound signal and transmits the digital sound signal to a recognition part. The recognition part converts the digital sound signal of "pretty" into text data of "pretty" while referring to sound recognition dictionary data stored in a sound recognition memory and transmits the text data to a text processing part. In the voice recognition dictionary data, a state that the frequency of using a word of "pretty" is high in the photography of pets is stored. Thereby even when voice input from the microphone can not be easily recognized, the voice of "pretty" can be easily recognized. The text processing part converts the text data of "pretty" into an image. A composition part composes the text shape data into a photographic image to prepare a composite photographic image.

Abstract: PROBLEM TO BE SOLVED: To provide an imager capable of determining a subject having high possibility of user's intention as a main subject even when a plurality of subjects exist.
SOLUTION: When a plurality of faces detected by face detection processing exist, it is necessary to determine which face is to be applied to the operation of an exposure value. Generally, a photographer takes a picture of a person to be a subject while talking with the subject. Thereby main subject determination processing determines a face whose mouth is moving when human voice is detected as a main subject. The main subject determination processing is performed by DSP during the display of a through image on an LCD 114.

Abstract: PROBLEM TO BE SOLVED: To obtain an imaging apparatus which is stably focused on a subject even if vibration is applied to the imaging apparatus. SOLUTION: An AF sensor is attached to a top surface of an AF stage. The AF stage has an X-direction stage motor and a Z-axis direction stage motor for driving the AF stage in an X-axis direction and a Z-axis direction. When a digital camera moves, a DSP arithmetically calculates moving positions in an X direction and a Z direction of the AF stage by using an X-direction angular velocity and a Y-direction angular velocity received from an X-direction angular velocity sensor and a Y-direction angular velocity sensor, and transmits the calculated moving positions in the X direction and the Z direction to an AF stage drive circuit. The AF stage drive circuit calculates voltage to be applied to the X-direction stage motor and the Z-direction stage motor according to the respective moving positions and applies the calculated voltage thereto. Thus, the AF stage moves in the X-axis direction and the Z-axis direction relative to a fixed part so as to negate movement of the digital camera. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To obtain an imager capable of achieving focusing by using contrast AF, even in an environment where flickers are produced.
SOLUTION: In the step S701, a DSP detects flickers contained in a digital image signal. In the step S702, whether the influence due to the flickers to a digital image signal is large is determined. When the influence of the flicker is large, processing progresses to the step S703. In the step S703, light-emitting timing of an AF auxiliary light source is calculated by using the cycle and phase of the flicker. The cycle and phase of the flicker are detected by the DSP by using a digital image signal. The same cycle and reverse phase relative to the cycle and phase of the flicker are used for the light-emitting timing of the AF auxiliary light source. In the step S704, the DSP transmits a signal to an LED drive circuit, and the AF auxiliary light source is made to flicker in light-emitting timing calculated, in the step S703.

Abstract: PROBLEM TO BE SOLVED: To reduce unnaturalness of a dynamic image before and after switching from a mechanical vibration-proof function to an electronic vibration-proof function.
SOLUTION: The digital camera 10 includes an imaging element 12, a remaining quantity detection circuit 22, and a battery 23. The digital camera 10 also has the mechanical vibration-proof function and the electronic vibration-proof function. When the camera 10 is switched to a dynamic image mode, the remaining quantity detection circuit 22 detects the remaining quantity of the battery 23. If the voltage of the battery 23 is above a second threshold value, an area to be imaged as a dynamic image is set to the effective imaging area of the imaging element 12. If the voltage of the battery 23 is below the second threshold value, the area to be imaged as a dynamic image is set to an area as large as the dynamic image area. When the voltage of the battery 23 in the start of photographing a dynamic image is above a first threshold Vth1, the mechanical vibration function is performed. If the voltage of the battery 23 in the start of photographing the dynamic image is below the first threshold Vth1, the electronic vibration-proof is performed.

Abstract: PROBLEM TO BE SOLVED: To switch execution/stop of a predetermined function with a simple operation. SOLUTION: A digital camera 10 includes: an imaging element 12; a DSP 15; a gyro sensor 19; a vibration prevention mechanism 20; a backlight 23; and a backlight driving circuit 24. The digital camera 10 has a vibration prevention function and an energy saving function. The optical axis deviation of the imaging element 12 is corrected by the vibration prevention mechanism 20 on the basis of a speed detected by the gyro sensor 19 in the ON state of the vibration prevention function. In the ON state of the energy saving function, the emitted light amount of the backlight is reduced by the backlight driving circuit 24. The DSP 15 discriminates whether the moving speed of the digital camera 10 in the vertical/horizontal direction exceeds a threshold V1. When the moving speed in the vertical direction exceeds the threshold V1, the ON/OFF of the vibration prevention function is switched. When the moving speed in the horizontal direction exceeds the threshold V1, the ON/OFF of the energy saving function is switched. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a mode switching system which switches a power consuming unit to an energy-saving mode at an appropriate timing.
SOLUTION: When the power source of a digital camera is turned on, the system drives the digital camera in a regular mode (S100). A switching threshold value Ts is set to 20 sec (S101). Time measurement is started (S102). When an elapsed time T exceeds the switching threshold value Ts, the digital camera is switched to the energy-saving mode (S105). If an input operation is performed before the elapsed time T exceeds the switching threshold value Ts, the regular mode is performed. After the input operation, the switching threshold value Ts is set to 5 sec. The elapsed time T is reset to 0 second and time measurement is started again (S102).
