Read controller for image pick-up device, and image pick-up apparatus
View Patent ↗A digital camera that captures object light by a CCD to create an image signal includes a read controller that controls reading of light signals from at least two fields of the CCD, in which a field, from which a light signal received by an R-sensor sensitive to red light is read, is separated from a field from which a light signal received by a B-sensor sensitive to blue light is read. The read controller includes: a color temperature discriminating section that discriminates a color temperature based on the light signals received from the CCD; and a read sequence controller that causes a light signal to be read first from the R-sensor when a color temperature is low and causes a light signal to be read first from the B-sensor when the color temperature is high according to a result of discrimination of the color temperature discriminating section.
1. A read controller for an image pick-up device that controls reading of light signals from at least two fields in which a field, from which a light signal received by an R-sensor sensitive to red light is read, is separated from a field from which a light signal received by a B-sensor sensitive to blue light is read, the read controller comprising:
a color temperature discriminating section that discriminates a color temperature based on the light signals received by the image pick-up device; and
a read sequence controller that changes a read sequence of the fields according to a result of discrimination executed by the color temperature discriminating section.
2. A read controller for an image pick-up device according to claim 1 , wherein the read sequence controller causes a light signal to be read first from the R-sensor when the color temperature is low and causes a light signal to be read first from the B-sensor when the color temperature is high according to a result of discrimination executed by the color temperature discriminating section.
3. An image pick-up apparatus that captures object light by an image pick-up device and creates an image signal, the image pick-up device being an interlace reading type image pick-up device that reads light signals from at least two fields in which a field, from which a light signal received by an R-sensor sensitive to red light is read, is separated from a field from which a light signal received by a B-sensor sensitive to blue light is read, the image pick-up apparatus comprises:
a color temperature discriminating section that discriminates a color temperature based on the light signal received by the image pick-up device; and
a read sequence controller that changes a read sequence of the fields according to a result of discrimination executed by the color temperature discriminating section.
4. An image pick-up apparatus according to claim 3 , wherein the read sequence controller causes a light signal to be read first from the R-sensor when the color temperature is low and causes a light signal to be read first from the B-sensor when the color temperature is high according to a result of discrimination executed by the color temperature discriminating section.
