Abstract

A capturing device includes an image sensor that generates an image signal by performing photoelectric conversion for light from a subject, a control unit that generates a setting value for setting a range where an image resulting from the image signal is cut, based on a first instruction input from a user, a setting value storage unit that stores the setting value generated by the control unit, an image conversion unit that reads the setting value from the setting value storage unit, and cuts a specific region specified by the setting value from the image and enlarges the cut region, when there is a second instruction input from the user, and an output unit that converts a signal of the image cut and enlarged by the image conversion unit into an image signal of a predetermined format and outputs the converted image signal.

Claims

1. An automotive camera system for use in a vehicle, comprising:

a memory configured to store a setting value for enlarging an image generated by an image sensor when the automotive camera system is in a powered on state; and

circuitry operable when the automotive camera system is in the powered on state and configured to

control generation of an enlarged image of a specific region of the image generated by the image sensor in response to an input instruction, the amount of enlargement determined by the stored setting value;

control display of information corresponding to the enlarged specific region, the information representing a state that a displayed image is enlarged;

control output of the enlarged image of the specific region;

and

control output of the image generated by the image sensor when the automotive camera system is changed to the powered on state.

2. The automotive camera system of claim 1, wherein the image generated by the image sensor includes the enlarged specific region and a portion of the vehicle.

3. The automotive camera system of claim 2, wherein the enlarged specific region includes the portion of the vehicle.

4. The automotive camera system of claim 1, wherein the stored setting value is configured to be set in a factory.

5. The automotive camera system of claim 1, wherein the setting value is configured to be set by a user operation, and

wherein the memory stores the setting value set by the user operation.

6. The automotive camera system of claim 1, wherein the circuitry is configured to control generation of plural kinds of enlarged specific regions, and

wherein the circuitry is configured to control the output of a selected one of the plural kinds of enlarged specific regions.

7. The automotive camera system of claim 1, wherein the image sensor comprises a CMOS image sensor.

8. The automotive camera system of claim 1, wherein the information represents zoom magnification for the enlarged specific region.

9. The automotive camera system of claim 1, wherein the circuitry is configured to control the output of the image generated by the image sensor following a predetermined time after the image signal corresponding to the enlarged specific region is output.

10. The automotive camera system of claim 1, wherein the input instruction is an instruction for displaying the enlarged specific region on the display unit.

11. The automotive camera system of claim 1, wherein the memory, the image sensor and the circuitry are disposed in a capturing device.

12. The automotive camera system of claim 11, wherein the capturing device is installed in a rear portion of the vehicle, and

wherein a display unit separate from the capturing device is installed inside the vehicle.

13. The automotive camera system of claim 1, wherein the circuitry utilizes NTSC standard for outputting at least one of the image signal corresponding to the image generated by the image sensor and the image signal corresponding to the enlarged specific region.

14. An automotive camera system for use in a vehicle, comprising:

memory configured to store a setting value for enlarging an image generated by an image sensor when the automotive camera system is in a powered on state; and

circuitry operable when the automotive camera system is in the powered on state and configured to

control generation of an enlarged image of a specific region of the image generated by the image sensor in response to an input instruction, the amount of enlargement determined by the stored setting value;

control display of information corresponding to the enlarged specific region, the information representing a state that a displayed image is enlarged;

control output of the enlarged image of the specific region;

and

control to not output the enlarged image of the specific region when the automotive camera system is changed to the powered on state.

15. A method for processing an image signal from an image sensor in an automotive camera system, comprising:

generating an enlarged image of a specific region of an image generated by the image sensor in response to an input instruction, the amount of enlargement determined by a stored setting value;

controlling display of information corresponding to the enlarged specific region, the information representing a state that a displayed image is enlarged;

controlling output of the enlarged image of the specific region; and

outputting the image generated by the image sensor when the automotive camera system is changed to a powered on state.

16. The method of claim 15, further comprising storing the setting value for enlarging the image generated by the image sensor when the automotive camera system is in the powered on state.
